Title: Manufacture of piezoelectric vibrator
Inventor: TANAKA HIROYOSHI
IPC: H03H3/02
Filed: 1994-09-22
Abstract: PURPOSE: To prevent an insulation resin from being cracked or a defective external appearance from being caused by applying a heat melting substance comprising plural constituents whose melting points differ from each other to a vibration part of the vibrating element, covering the entire element with a thermosetting insulation resin and removing the heat melting substance to form an air gap around the vibration part. CONSTITUTION: A piezoelectric vibrator 1 is fixed by connecting an electrode provided to both sides of the vibrator 1 with a connection conductor 3 made of a solder or a conductive adhesives or the like respectively. A heat melting substance 4 such as a wax or a paraffin is applied around the vibration part of the vibrator 1 and the vibrator 1 is immersed in a solution in which a thermosetting insulation resin such as a durene is solved by a solvent thereby coating a main body other than the lower part from a terminal 2 with an insulation resin 5. After the resin 5 is dried, the vibrator 1 is heated up to around 150 deg.C to form an air gap around the vibrator 1 by curing the resin 5 and also allowing the heat melting substance 4 to be absorbed by the resin 5.  The heat melting substance 4 is made up of plural constituents whose melting point differs from each other to prevent production of cracks.

Abstract: PURPOSE:To rapidly detect foreign materials, by discriminating the presence of foreign materials bitten by a power window when more differential value than an ordinary one of current is detected in the differential detection circuit during the closing motion of the power window or the like. CONSTITUTION:A manual up-actuation treatment is carried out and when it is discriminated that an up-switch UPSW has been turned on, line X is made active to output the up-signal to the relay drive circuit 5 and excite relay coil Lx. Next, switch Sx is changed over and current is conducted in a motor 6 to drive the motor 6 and the power window is moved to the closing direction. CPU 1 discriminates whether the differential signal (a) output from the differential detection circuit 7 is detected. When it is YES, it is discriminated that foreign materials are bitted during the closing motion of power window and the motor is driven reversely to the opening side. When it is NO, it is discriminated whether lock current is detected or a detection signal is output from an absolute value detection circuit 8. Then the procedure is returned.

Title: Memory control system in facsimile equipment
Inventor: KOSHIISHI TAKAYASU
IPC: H04N1/21
Filed: 1984-12-05
Abstract: PURPOSE:To reduce the number of times for stopping an original with the reading speed of a scanner constant by increasing and decreasing the capacity of a read line memory by interlocking it with an original mode selection in terms of facsimile equipment. CONSTITUTION:The line memory is interlocked with a buffer memory, and addresses up to XH-X+l1H and those up to X+l1H-X+l2H are assumed to employed the line memory and the bubbler memory in a normal mode, respectively. Here, when an original mode is switched from STD to DTL, original feed attains a density twice with the reading speed unchanged. Therefore said original obtains the line number twice at the time of the STD to double approximately the number of times for stopping the original. If the address in the line memory is increased from X+l1H-X+2l1H in the DTL mode, the line number read once is doubled, and the number of times for stopping the original becomes same as in the STD mode, whereby a noise and feed irregularity can be reduced.

Title: Constant-current circuit and oscillation circuit
Inventor: SUWADA MAKOTO
IPC: H03K4/502
Filed: 1990-09-26
Abstract: PURPOSE:To curtail the hardware quantity and the power consumption and to reduce the cost by varying smoothly a current value and an oscillation frequency allowing them to follow a power supply voltage, in a miniature/low power consumption device such as a note personal computer. CONSTITUTION:When a value of a power supply voltage Vcc is V4, voltage dividing resistances R2, R3 of a differential amplification input part 4 are adjusted so that an input voltage V2 of a differential amplifying part 3 becomes equal to a constant-voltage V1 of an output of a reference voltage part 1. In this case, a current I3 flowing through R4 is '0'. Subsequently, when the power supply voltage rises and comes to V2>V1, I3 flows to the VA side from the VB side. On the other hand, when the power supply voltage drops and comes to V2<V1, I3 flows to the VB side from the VA side. That is, when Vcc increases by setting Vcc=V4 as a boundary, I2 increases, and when Vcc decreases, I2 also decreases. Inclination of this characteristic is varied by a value of R4.
