Title: Recording and reproducing device
Inventor: SUENAGA HARUO
IPC: G11B27/34
Filed: 1985-03-19
Abstract: PURPOSE:To make a display very easy to see by recording to a rear track to normal direction of two tracks in which recording is made when a frame picture signal is selected. CONSTITUTION:Inputted picture signals 5 are converted to specified signals through a record processing circuit 6 and recorded by a recording and reproducing head (magnetic head) 7 in a magnetic sheet 4 which is drove rotatively by a sheet motor 3, and signals taken out by the magnetic head 7 are reproduced to reproduction picture signals 9 through a reproduction processing circuit 8. Accordingly, plural picture tracks are formed concentrically on the sheet 4, and become 1 track, 2 track,... from outer peripheral side. A microprocessor 12 outputs the track number of the sheet 4 with which the magnetic head 7 is abutted and displays in a display device 14 following the movement. Thus, as positional information of the magnetic head shown in the display device is the same and does not change, the display becomes very easy to see.

IPC: H01L21/3205
Filed: 1986-03-14
Abstract: PURPOSE:To remove completely adhering unnecessary films without reducing the thicknesses of deposited films by a method wherein a protective film against etching is deposited by an evaporation method with high orientation on the deposited films which are not to be etched before the unnecessary films on side walls are removed and then the unnecessary films are etched. CONSTITUTION:A stencil 32 which has overhangs at its shoulder parts is formed on a substrate 31 and then an Nb layer 33(1), an Al2O3 layer 33(2) and an Nb layer 33(3) are formed on the substrate 31. Unnecessary films 34 formed on both of the side walls of the stencil 32 are shown in the figure. Then, an Nb/Al2O3/Nb layer can be formed on the substrate 31 by removing the films deposited on the stencil and an Si protective film formed on the Nb layer 33. The Nb/Al2O3/Nb laminated films 33(1)-(3) are formed by magnetron sputtering and the Si protective film 36 is formed by electron beam evaporation. The unnecessary films 34 which adhere to the side walls are completely removed by etching the whole substrate by BGl3+CCl4 of 15 Pa for 2 minutes in a parallel plate type reactive ion etching apparatus. With this constitution, the unnecessary films adhering to the side walls can be removed completely without damaging deposited films so that the yield of multilayer interconnection can be improved.

Filed: 1992-03-13
Abstract: PURPOSE:To make a pitch between conductor patterns finer by forming a BPSG film as a first dielectric film on a substrate, forming a SiO2 film as a second dielectric film on the side surface of a first interconnection, and forming an interlayer dielectric film as a third dielectric film. CONSTITUTION:A SiO2 film 6 is deposited on a Si substrate 1 on which circuit elements, a dielectric film (BPSG film) 2, and first wirings 4A-4C made of a multilayer film are formed. Then, the SiO2 film 6 is subjected to anisotropic etching by dry etching, so that the surface of the first wiring 4 is exposed. SiO2 films 7A-7F are formed on the side surface of the first wiring 4. Then, an interlayer dielectric film is formed by depositing SiO2 film 10 owing to a thermal decomposition reaction of oxygen which contains TEOS and ozone. This causes the surface of the substrate 1 to become one type of metal film surface, that is the dielectric film 10. Hence, it is possible to prevent the occurrence of an overhang and to embed a finer spacing between wirings.

Abstract: PROBLEM TO BE SOLVED: To correct the posture of a workpiece easily into an appropriate posture by the rotation of rollers by forming stoppers and clamps of idling rollers standing upright to the transfer face of a conveyor at least at the time of being protruded. SOLUTION: Upon detecting the stop of a workpiece 5 by a contact switch or a contactless switch, clamps 6 are protruded onto the transfer face of a roller conveyor 2 by a driver so as to press the rear end part of the workpiece 5. At this time, in case of the workpiece 5 entering obliquely and being stopped in that state, couple of rotation is generated on the workpiece 5 due to asymmetry of stoppers 4 and the clamps 6, and sliding direction force acts upon the contact faces of the stoppers 4 and clamps 6 with the workpiece 5. The contact parts of the stoppers 4 and clamp 6 are made idling rollers 4A, 6A so as to be freely rotated. The workpiece 5 is therefore rotatory-displaced and corrected in its posture without getting stuck.

Title: Control method of constant speed running device for vehicle
Inventor: SUGANO TOMOAKI
IPC: B60K31/00
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain compensation coefficients which correspond to vehicle characteristics to be changed, by obtaining an integral term by multiplying and integrating a predetermined coefficient by a deviation between actual car speed and target car speed and obtaining each compensation coefficient by subtracting the integral term from a compensation coefficient for acceleration when acceleration control is done and adding the integral term to a compensation coefficient for deceleration when deceleration control is done, respectively. SOLUTION: In the detection of car speed, target car speed Vm is subtracted from actual car speed Vn to obtain a car speed deviation ε (ST1). Acceleration reference value α is multiplied by a constant D, the car speed deviation ε is multiplied by a constant P, and they are added to obtain a basic control amount S (ST32). The car speed deviation ε is multiplied by a constant I to integrate per cycle and obtain an integral term TI (ST4). When the basic control amount S is positive, a compensation coefficient for acceleration K is obtained by subtracting the integral term TI from a compensation coefficient for acceleration KA (ST7), and when the basic control amount S is negative, a compensation coefficient for deceleration control K is obtained by adding the integral term TI to a compensation coefficient for deceleration KD (ST6).  Upper and lower limit values of the compensation coefficient K are checked (ST8, ST10) and are processed according to the procedures, and the compensation coefficient K which is determined is multiplied by the basic control amount S to obtain control data DATA as a final control amount (ST12). As a result of running control, constant speed running control in which actual car speed agrees with target car speed in correspondence to fluctuations of vehicle characteristics becomes possible.

IPC: H03M1/74
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a D/A converter hardly causing overshoot in the analog output while suppressing the power consumption. SOLUTION: This converter is provided with a constant current source 1, switch circuits SW1 and SW2, a switch circuit SW3 connected between the constant current source 1 and the switch circuit SW1, an output resistance 2, a dummy resistor 3, and a control circuit 4, and each switch is switched and controlled by a control signal from the control circuit 4.
