IPC: H04R31/00
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To make a sound matching layer uniform in thickness, small in variance, and superior in economy and to improve transmission and reception characteristics of an ultrasonic wave by forming the sound matching layer by providing a couple of limiting materials of constant height on a piezoelectric plate and applying molten resin, and pressing the top surface. SOLUTION: On a backing material 1, the piezoelectric plate 3 having electrodes 2a and 2b on both its main surfaces is fixed and at both end parts on a 1st-layer (glass) 4a, limiting materials 5a and 5b, such as resin rods, which have a height of λ/4 are fixed. The 1st layer 4a is coated with molten resin made of the same materials with the limiting materials 5a and 5b. Then a press plate 6 having, for example, the top surface made flat is pressed against the molten resin. Consequently, an excess of the molten resin is extruded to form a 2nd layer 4b which has λ/4 thickness. After sound matching layers 4a and 4b are formed, a cut reaching the backing material 1 from the sound matching layers is formed to obtain divided piezoelectric elements, thus forming an array type probe.

Title: Output buffer circuit
Inventor: OZAWA YOICHI
IPC: H03K17/16
Filed: 1990-11-08
Abstract: PURPOSE:To reduce a through-current at an output stage by providing a depletion MOS transistor(TR) to a C-MOS inverter driving a MOS TR at the output stage. CONSTITUTION:Since depletion MOS TRs D1, D2 are always turned on because a gate level is not lower than the ground level and act like constant current elements. When a level of an input signal at an input terminal 4 changes from L to H, output signals of C-MOS inverters 1b, 2b go from H to L, a P-channel MOS TR P1 at the output stage transits from OFF to ON and an N-channel MOS TR N1 transits from ON to OFF. In this case, the TR D1 acts like a constant current element, the on-state of the TR P1 transits slowly and the TR N1 transits to the OFF state rapidly. Thus, the time when the TRs P1, N1 are simultaneously turned on is reduced and a through-current is reduced.

Title: System for observing program executing process
Inventor: YONEDA KIYOSHI
IPC: G06F11/28
Filed: 1987-11-30
Abstract: PURPOSE:To omit an external memory which stores the program observing results by reading freely reading the address and the data which are used by the instruction carried out immediately before a single step interruption within an interruption processing program. CONSTITUTION:A CPU1 contains register groups 3-6 which hold the address and data carried out right before a single step interruption. In this case, the addresses fetched by an input origin address latch register group 3 and an output destination address latch register group 5 include the memory address, the register number address, the input/output device address, and the information which discriminates these three types of addresses. Then an interruption processing program 12 of an internal memory 10 prepares the instructions which refer to those register groups 3-6 and carries out these instructions for observation of the executing process of a program to be debugged. Thus an external memory which stores the program observing results is eliminated.

Title: Method of driving gas discharge panel
Inventor: KONOUE AKIHIKO
IPC: G09G3/291
Filed: 1988-12-02
Abstract: PURPOSE:To prolong the life of the gas discharge panel by initiating neither auxiliary discharging nor switching discharging unless display discharging is performed. CONSTITUTION:Line sequential scanning pulses are applied to a 1st electrode and discharge control pulses synchronized with the scanning pulses are applied to the 2nd electrode of a discharge cell which does not cause 2nd discharging, so that 1st discharging is not initiated. Namely, a cathode pulse 100 and anode pulses 120 and 121 have the same respective electrode applied waveforms unless the display discharging is performed, but pulses applied to an auxiliary anode are the discharge control pulses 130 having almost the same pulse with the cathode pulse. In this case, the potential difference between a cathode and an auxiliary anode is small in a section I in a figure, so the 1st discharging is not caused. There is no charged particle at the periphery of the cathode and in a display discharge space and 2nd discharge is not caused either. Further, 3rd discharging is initiated even by the anode pulses applied to the anode in a section II. Consequently, the discharging time is shortened and the life of the panel is prolonged.

Title: Manufacture of pole plate for lead acid battery
Inventor: TAKAMA TETSUO
IPC: H01M4/22
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To shorten a maturing time of a pole plate by sticking alkali solution to a collector and specifying the maturing condition of the pole plate full of pasted therein. SOLUTION: The maturing temperature is set to 60 to 100 deg.C. Then, drying times required in a constant rate drying process or in a reducing rate drying process can be shortened. Also, in the processes of constant rate drying and the process of reaction, such reactions take place that lead in a collector becomes ions and dissolves from the collector in paste and lead makes reaction with oxide in the air to become a lead oxide (equations I, III) so that the collector and the active material make connection between themselves. Namely, for the purpose of advancing reactions supply of lead solution and oxygen must take place simultaneously. Meanwhile, since alkaline material is stuck to the collector, even if hydro-oxide ion is consumed in equation III, pH does not drop so much and the lead dissolution is in its state liable to progress.  Since the pole plates matures in this state in an atmosphere with the oxygen concentration from 30% to 100%, the oxygen is sufficiently supplied and the reaction shown in equation II may progress smoothly.

Filed: 1990-11-09
Abstract: PURPOSE:To reduce a wt. as a whole to reduce cost by constituting the metal net-like decorative panel body in a metal decorative panel of at least either one of a light metal and a light alloy. CONSTITUTION:Longitudinal rods 2a and lateral rods 2b are subjected to plain weave processing to form a metal net-like body which is, in turn, placed between the pressure plates 3 of a press machine to be subjected to plane press processing. By this method, a planar decorative surface 2c is formed to the surface part of the metal net-like body. Thereafter, golden color anodizing finish is applied to the surface part as anodic treatment and the whole is coated with an aluminum oxide layer. A brass powder 5 is sprayed to the entire surface using a thermal spraying nozzle 4 to form a brass powder layer 2d to the surface. Finally, hairline finish is applied to the surface using a flat file to form a decorative panel body 2. Since the decorative panel body is composed of aluminum in a metal decorative panel, the wt. of the whole is reduced to about 1/3 that of a conventional one and, as a result, cost is also reduced.

Filed: 1987-12-02
Abstract: PURPOSE:To ensure the similar actuation to a compiler type language processing system at the processing carried out by a program and to shorten the processing time by starting an interpreter part at the sequential processing carried out by a command and to start an object code generating part at the processing carried out by a program respectively. CONSTITUTION:An input source program undergoes the analysis of the syntax structure through an intermediate code generating part 1 and is converted into an intermediate code of a reverse polish notation, a tree structure, etc. A decid ing part 6 counts the units divided by the ODH (carriage return) contained in a character string of an input intermediate code. Then the part 6 decides the sequential processing carried out by a command when said counted value is equal to 1 and starts an interpreter part 3. Thus the part 3 interprets and carries out the intermediate code. While the part 6 decides the processing carried out by a program in case the character string of the input intermediate code contains plural units divided by the ODH. Thus the part 6 starts an object code generating part 4.

Title: Light measuring method and exposure control method
Inventor: TERASHITA TAKAAKI
IPC: G03B27/73
Filed: 1988-12-01
Abstract: PURPOSE:To accurately perform light measurement and exposure control after the variation of a light source by generating a color filter calibration curve which indicates the relation between the setting position of a color filter and a light measured value after the variation of the light source and finding the filter position where a predetermined light measured value is obtained. CONSTITUTION:The color filter position Pb corresponding to the predetermined light measured value Pa is found by using the color filter calibration curve B obtained by performing color filter calibration after the variation of the light source and each color filter is set at the found color filter position to measure light. Therefore, the light quality of the light source is adjusted to the light quantity before the light source variation by the color filter interposed in an optical axis at a specific position, so the light measured value of a color original image does not vary without reference to whether the light source varies. Consequently, when the quantity of exposure is determined, the quantity of variation in the light measured value need not be detected and the quantity of exposure is corrected by easy operation.

Title: Spray nozzle
Inventor: SAKAMOTO TOSHIO
IPC: B05B7/04
Filed: 1990-11-09
Abstract: PURPOSE:To decrease the bouncing back of the fine grains of liquid on the surface of an object to be sprayed and to improve coating material deposition efficiency by drilling an air supply valve in a needle valve to form an air discharge port to the front end of the needle valve. CONSTITUTION:The required liquid L is supplied under pressurization from a liquid tank to a liquid nozzle 22 and compressed air is supplied from a compressed air source to the air supply hole 25, an air passage 27 and a 2nd air passage 28. The liquid L is ejected from an ejection port 22a via the inside of the liquid nozzle 22 when the needle valve 24 opens the liquid nozzle 22. A small amt. of the compressed air is mixed with the liquid in the low-speed state from the air discharge port 26 at the front end of the needle valve 24 and, therefore, the relatively easy incorporation thereof is possible. Since the air ejection port 26 is formed like a collar, the rectilinearity of the air ejected from this air discharge port 26 is lost and the air is uniformly and successfully dispersed and supplied into the liquid. The pulverization by the air of the low pressure and the small flow rate is executed in this way.

IPC: H03F3/45
Filed: 1991-11-20
Abstract: PURPOSE:To reduce a parasitic capacitance fed to an output terminal by selecting substantially a parasitic capacitor between a collector and a base of a transistor(TR) fed to the output terminal to be that for one base ground TR pair. CONSTITUTION:Differential TR pairs 141-14m+n are divided into plural groups 211-21m and output terminals of all the differential TR pairs 141-14m+n in each of the groups 211-21m are connected in common to input terminals of base ground TR pairs 151-15m respectively. Then output terminals of the TR pairs 151-15m are connected to an input terminal of a base ground TR 16. Thus, the parasitic capacitance between the collector and the base of the TR fed to the output terminal 19 is selected substantially to be the parasitic capacitance between the collector and the base of one TR of the TR pair 16, and the parasitic capacitance between the collector and the base of the TR fed to the output terminal 20 is selected substantially to be the parasitic capacitance between the collector and the base of the other TR of the TR pair 16. As a result, the parasitic capacitance fed to the terminals 19, 20 is reduced.

Title: Ink jet printer head
Inventor: SATO TSUTOMU
IPC: B41J2/055
Filed: 1990-11-09
Abstract: PURPOSE:To improve a dot density and enhance a printing speed by a method wherein a partition wall of an ink flow path is composed of a deforming wall having elasticity all over the surface thereof, and ink is flown by applying a voltage to a piezoelectric actuator bonded thereto. CONSTITUTION:An upper opening of a flow path body 1 is covered with an elastic deforming wall 2. A plurality of piezoelectric actuators 3 which are vertically polarized are bonded thereon. A pair of electrodes 4, 5 are bonded on the both ends of the piezoelectric actuator 3 in the orthogonal direction to the polarization. By applying a positive voltage (+V) to the selected electrode 4, one end of the piezoelectric actuator 3 is shear deformed downward because the other end is fixed to a nozzle plate 6, a part of the corresponding deforming wall 2 is pressed, ink is compressed, and an ink drop is flown from a nozzle 9. Because ink flow paths 7 adjacent to each other are parted by a common partition wall 8, the ink flow paths 7 can be arranged at small intervals. Because the deformation of the deforming wall 2 on one ink flow path 7 does not affect the adjacent ink flow path 7, the piezoelectric actuators 3 can be simultaneously driven, and a printing speed can be improved.
