Title: Semiconductor device and photoelectric transfer apparatus using it
Inventor: MORISHITA MASAKAZU
IPC: H01L29/737
Filed: 1989-03-29
Abstract: PURPOSE:To obtain a semiconductor device having large current amplification and little variation in characteristics by a method wherein an emitter region is formed after oxide on a base region has been removed while the emitter region is formed of a single crystal. CONSTITUTION:This is a semiconductor device of a bipolar transistor structure wherein an emitter region is deposited on a base region to be formed and wherein the emitter region 5 is formed after oxide on the base region 4 has been removed. In other words, since an oxide film has not been formed between the emitter region 5 and the base region 4, variation in characteristics among BPT can be eliminated. In addition since the emitter region 5 is formed of monocrystalline silicon, current amplification can be increased though no oxide film has been formed between the emitter region 5 and the base region 4.

IPC: G11B5/187
Filed: 1990-03-27
Abstract: PURPOSE:To obtain a large overwriting characteristic even with a low exciting current by efficiently admitting the magnetic flux from a ferite core to a magnetic flux from a ferrite core to a magnetic thin film having a high saturation magnetic flux density. CONSTITUTION:A magnetic gap-facing surface and a surface A which is the surface continuous with this surface are formed of the thin magnetic film formed on the ferrite. The surface A regulates the extension range thereof by the surface B intersecting diagonally therewith. The length from the medium-facing surface to the intersected point of the surface A and the surface B is designated as l and a writing current is designated as 20mAo-p, then the dependency of the overwriting characteristic to the medium having 1200 Oe coercive force on the length l is as shown by a curve shown in Fig. Namely, the value of overwriting evidently increases successively if the l is <=100mum. The remarkable effect of improving the overwriting characteristic is, therefore, obtd. by limiting the value of the l to <=100mum.

Title: Rectifier circuit
Inventor: OKUBO BUNICHI
IPC: H03G3/30
Filed: 1985-04-12
Abstract: PURPOSE:To decrease the attach time when a signal change quantity is large by connecting the 2nd detection transistor (TR) having a different detection level from the 1st detection TR in parallel therewith. CONSTITUTION:The 2nd detector TR 10 is activated when the collector potential of a TR 6 reaches a voltage conducting TRs 15, 10 or over, and since the collectors of the 1st detection TR 9 and the 2nd detection TR 10 are connected, an output current appearing an output terminal 13 is a current sum of both the detection TRs 9, 10. Thus, when the input signal change quantity is large, the 2nd detection TR 10 is activated and the sum of charging currents to smoothing circuits 11, 12 flows from the TRs 9, 10, then the circuit time constant is small and then the attach time being the response time when the input signal level is changed largely suddenly is made small.

Title: Production of liquid crystal cell
Inventor: HISATAKE YUZO
IPC: G02F1/133
Filed: 1988-03-30
Abstract: PURPOSE:To prevent the generation of static electricity at the time of taking out a liquid crystal cell and to obviate the generation of a short circuiting between transparent electrodes by the breaking of the insulating layer between the transparent electrodes by providing an antistatic film on the inside surface of a film for vacuum packing. CONSTITUTION:The antistatic film 13 is formed on the inside surface of the film 10 for vacuum packing. Namely, the film for vacuum packing which executes heating and curing of the adhesive agent of the liquid crystal cell has the antistatic film on the inside surface thereof and, therefore, this film for vacuum packing hardly adheres to the substrate surface of the liquid crystal at the time of pressure reduction and heating; in addition, the generation of static electricity at the time of stripping the film for vacuum packing from the substrate is obviated when the liquid crystal cell is taken out after sealing of the film for vacuum packing. The breakage of the insulating layer by static electricity is thereby obviated even with the liquid crystal display element such as active matrix liquid crystal display element in which the transparent electrodes provided on the substrates are superposed on each other via the insulating layer. The generation of the short circuiting between the transparent electrodes is thus obviated and the normal display without having defects is effected.

Filed: 1989-03-31
Abstract: PURPOSE:To extremely reduce feeding loss inexpensively with simple circuit constitution by connecting a speaker in a master set between a power output and a speech line and supplying power to a slave set via the speaker. CONSTITUTION:A power output of a master set 31 is fed to a speech line 33 via a reception speaker 41 and to a slave set 35. The DC resistance of the speaker 41 is normally comparatively low and the AC resistance is high. Thus, no voltage loss almost takes place in the feeding circuit. Because of high AC impedance, even when the speaker 41 connects to the speech line 33, adverse effect such as attenuation of a speech signal is not caused. Thus, it is not required to use an exclusive circuit device such as a choke coil or a pseudo inductance circuit for a feeding circuit, the circuit constitution is simplified, number of components is reduced and the device cost is decreased and the voltage loss by the feeding circuit is almost eliminated.
