Title: Controller for motor of reproducer
Inventor: HIOKI TOSHIAKI
IPC: H02P29/00
Filed: 1982-12-16
Abstract: PURPOSE:To stably and accurately control the speed of a motor by FM-demodulating a reproduction signal to detect a synchronous signal, and forming a motor control signal on the basis of the synchronous signal. CONSTITUTION:A signal recorded on a disc 1 is reproduced by a pickup 2, and is inputted to an FM demodulator 3. An FM demodulation signal is inputted to a clamp circuit 4, a synchronizing signal is produced, and is applied to a motor control signal generator 5. The generator 5 generates a motor control signal on the basis of the synchronizing signal, and the motor control signal is applied through switching means 7 to a phase comparator 8. The output of the comparator 8 is applied through a low pass filter 11 to a motor 12, thereby controlling the speed of the motor 12.
Patent JP-H01205219-A (JP)
Title: Semiconductor integrated circuit
Inventor: TETSUKA AKITOSHI
IPC: G05F3/24
Filed: 1988-09-05
Abstract: PURPOSE:To minimize the change of a current to flow even when the voltage impressed to a constant current source circuit is changed by using that the current to flow is in proportion to the square of the voltage between gate sources and buffering the change of the voltage impressed to a constant current source circuit to the change of the voltage between small gate sources. CONSTITUTION:Since the threshold voltage of a second FETQ4 is set deeper than the threshold voltage of a first FETQ3 and the K value of the second FETQ4 is set larger than the K value of the first FETQ3, the second FETQ4 has a current driving capacity larger than the first FETQ3. The current to flow at a constant current source circuit is determined by the first FETQ3 and the first FETQ3 functions as an inherent current source. Further, the second FETQ4, by using that the current to flow is in proportion to the square of the voltage between gate sources, buffers the change of the voltage impressed to the constant current source circuit and is operated so as to minimize the change of the drain voltage of the first FETQ3. Thus, even when the voltage impressed to the constant current power source circuit is changed, the change of the current to flow is minimized.

Title: Manufacture of thin film el element and device for forming el emission layer
Inventor: KATO HISATO
IPC: H05B33/10
Filed: 1992-08-21
Abstract: PURPOSE:To form an emission layer of good reproducibility and of good crystallinity by preventing sulfur component from adhering to the surface of a target when the emission layer of an EL thin film element chiefly consisting of sulfides is formed by using a sputtering gas containing hydrogen sulfide. CONSTITUTION:Deposition of sulfur is prevented by sputtering the space between a film formation (glass) substrate 1 to be fitted in a positive electrode 4 and a target 2 fitted in a negative electrode 3, by forming the distribution of hydrogen sulfide concentration that is reduced in the vicinity of the surface of the target 2, into a sputtering gas. The same process applies to a case of reactive sputtering where a metal target is used as the target 2. The distribution of hydrogen sulfide concentration is formed by providing a pure Ar guiding port 7 near the negative electrode 3 of a reactive tank wall 10 in the side of the space between the positive electrode 4 and the negative electrode 3, and by providing a guiding port 8 of mixed gas of Ar and H2S near the negative electrode 4, and by evacuating them from the wall in the opposed side.

Filed: 1989-08-31
Abstract: PURPOSE:To make it possible to ensure the reading of a silver paste pattern by obliquely projecting light on a die stage for a lead frame to which a semiconductor chip is bonded by using conductive paste in the direction along one side of the semiconductor chip so that a high contrast ratio is imparted between the die stage and the silver paste. CONSTITUTION:Downward lighting is applied on a chip 2 which is mounted and bonded on a mat die stage 1 in the direction orthogonal to the die stage 1. A second light source 7 is provided so as to project light on the surface of the die stage 1 in the oblique direction. The light is projected in the direction orthogonal to the two facing sides of the chip 2. The illuminance of the surface of the die stage 1 becomes high because of the oblique lighting source 7. In the mean time, the illuminance of the surface of a silver paste 3 at the two sides which are in parallel with the oblique lighting source 7 does not become high with respect to the surface of the silver paste 3. High contrast is obtained between the silver paste and the die stage 1. In this way, the direction of the slant projecting light is alternately switched, and the pattern of the silver paste 5 which is swelling out the peripheral part of the chip can be read out.

The integrated electrolysis time is nearly in a proportional relationship with the quantity of water flowing on the alkaline side and with the quantity of accumulated scale. In this way, scale can be removed corresponding to the quantity of accumulated scale, thus preventing the accumulation effectively.

Abstract: PURPOSE:To continuously supply a new polishing material so as to maintain both cutting and polishing functions for a long period, by interposing an abrasive material of diamond or the like in the gap part of a material in which iron dust particles are combined in a ventilative porous state through an iron carbide part. CONSTITUTION:When an acoustic record needle of diamond is polished by using a polishing machine A, diamond powder, being successively supplied to a surface from a ventilative hole of the polishing machine A during the work, bites mainly a mild steel part 5 rather than a cast iron part 6, and the biting powders mutually perform cutting and thermal etching with the part of a surface in the mild steel part not bitten by the powder, further existence of the cast iron part 6 causes the machining pressure to be hardly applied to the mild steel part 5 at polishing, preventing cleavage of a work and generating more effectiveness of the cutting and the thermal etching. Then the powder, being interposed in a ventilative hole of the polishing machine and successively supplied, can continuously perform work for a long time.
