Patent JP-S5755610-A (JP)
Title: Synthesizer receiver
Inventor: NEZU SHIYUNICHI
IPC: H04B1/16
Filed: 1980-09-19
Abstract: PURPOSE:To automate accurate band width setting measuring the signal level ratio of a desired wave and a disturbing wave. CONSTITUTION:When a desired reception frequency is f0 and a nearby frequency is f0+ or -DELTAf, a code generation part 5 first outputs a frequency code corresponding to f0-DELTAf and a level detector 6 detects a current reception level. The code generation part 5 outputs a code corresponding to f0+DELTAf and the detector 6 detects its reception level similarly. Lastly, the code generation part 5 returns the reception frequency to the original reception frequency f0 and the level detector 6 detects the reception level again. A selection control part 7 compares the reception levels of the f0-DELTAf and f0+DELTAf with that of the f0 and selects the predetermined corresponding band width on the basis of the ratio.

Title: Electric discharging method and device
Inventor: KANEDA KIYOSHI
IPC: B23H7/28
Filed: 1990-05-23
Abstract: PURPOSE:To improve the machining efficiency by relatively retracting the machining electrode currently used from the machining stop position when machining abnormality occurs and restarting electric discharge machining with the machining electrode returned from the retraction position to the position where machining stops when the machine returns abnormal state to normal state. CONSTITUTION:Along with the occurrence of abnormal discharging state, i.e., short circuits caused by the entrance of electric discharge machining chips into the gap between the machining electrode and workpiece, the swinging movement of a machining electrode between the machining electrode 12 and the workpiece 14 is made to stop, and the chips causing abnormality are removed with the gap widened. After that, in the process of forming a gap for electric discharge with the machining electrode 12 and workpiece 14 approaching each other again the machining electrode 12 is returned to and positioned at the position C1 where swinging motion is stopped. Therefore, since the electric discharge machining after the returning to the normal state is restarted in the position C1 where electric discharge machining is stopped, the production of residual margin for electric discharge machining due to the occurrence of abnormality. Owing to this constitution machining efficiency in swinging machining process is improved.

Title: Phase difference detecting circuit
Inventor: SAKUMA SHUICHI
IPC: H04B7/08
Filed: 1992-05-25
Abstract: PURPOSE:To correct an error of a phase difference detection voltage due to the variance of parts with a simple circuit by providing a phase difference voltage correcting circuit which discriminates whether a correction voltage can be outputted or not. CONSTITUTION:A phase difference voltage A must be 0V if either of the main signal of an input terminal 1 and the SD signal of an input terminal 2 is not inputted. Consequently, it is discriminated whether signals are inputted or not by detection voltages of gain controllers 16 and 17, which detect the output levels of automatic gain controlled amplifiers 14 and 15, instead of detection of input signals of terminals 1 and 2. That is, a detection voltage B of the main signal and a detection voltage C of the SD signal are inputted to a phase voltage correcting circuit 20, and it is discriminated whether signals are inputted or not by detection voltages B and C, and a phase difference correction voltage D is outputted from the circuit 20 only when signals exist in both routes, but 0V is outputted when either of them does not exist. This voltage D and the phase difference voltage A are inputted to an amplifier 19 to obtain the phase difference voltage, where the delay time between the main signal route and the SD signal route is corrected, in an output terminal 4.

Patent JP-S6018873-A (JP)
Title: Tape cassette
Inventor: YOSHII TETSUJI
IPC: G11B23/087
Filed: 1984-06-26
Abstract: PURPOSE:To secure the stable tape drive and to reduce the accuracy required to each parts by decreasing the diameter of the center part of a hole formed at the center of a tape guide compared with upper and lower end parts of the hole and tilting the tape guide in accordance with the tape driving surface. CONSTITUTION:When a tape 15 is driven with an inclination to the circumferential surfaces of tape guides 4 and 5, these guides 4 and 5 are tilted on a fulcrum set at a small diameter part at the center between holes 4a and 5a of the guides 4 and 5 and in accordance with the tape inclination. This eliminates the partial sag of the tape 15 to ensure the smooth drive of the tape. For the displacement of the guides 4 and 5 produced along the tape driving surface, the guides 4 and 5 are slightly held upward with their circumferential surfaces set along the tape driving surface owing to the bias tension caused by the driving of the tape 15 although the lower surface sides of the guide 4 and 5 are held by a plane since the weight of these guides are very small. As the revolution of the guides 4 and 5 are inhibited, the unstable tape drive due to the outer circumferential vibration can be avoided.

When a predetermined amount of a photoresist 6 is dripped from a dripping nozzle 5 in this state, said photoresist 6 is dispersed to the entire surface of a wafer 4 by centrifugal force to be uniformly applied thereto. Because the excessive photoresist 6 scattered from the peripheral part of the wafer 4 is caught between a large number of needle like projections 8 comprising glass fibers implanted in the inner peripheral wall surface of the coating cup 1, it is prevented that said photoresist is impinged to the wall surface and splashed to be adhered to the film formed on the wafer 4.

Abstract: PROBLEM TO BE SOLVED: To prevent an etchant used for the removal of an adjacent sacrifice area from flowing into an active matrix by setting an iso-cutting area so as to be situated on the adjacent sacrifice area. SOLUTION: When a second thin film layer is iso-cut into M×N arrays of a second thin film electrode 265 by dry etching, the iso-cutting area 295 of the second thin film layer is set so as to be situated on a sacrifice area 340. Thus, since the cutting area 295 is situated on the adjacent sacrifice area 340 in the formation of an incomplete mirror structure 350, an etchant inflow preventing layer 230 is never damaged when a patterning is performed in the cutting area 295, and the etchant is carried only into the sacrifice area 340 when the adjacent sacrifice area 340 is removed, so that it never acts on a passivation layer 220 and an active matrix 210 situated under it.
