Title: Semiconductor device
Inventor: YAMAMOTO MUNEKORE
IPC: H01L21/331
Filed: 1992-12-17
Abstract: PURPOSE:To provide a current drive type semiconductor device which improves the current amplification factor without lowering breakdown strength properties. CONSTITUTION:A P-type base region 365 is made to has such a gradient that the depth of periphery becomes shallower as it goes from an N<+>-type emitter region 37 to a P-type base electrode region 35 adjacent to the N<+>-type emitter region 37 and that the concentration becomes thinner. At this time, the thickness Wba of the base right below the N<+>-type emitter region 37 is the same as a conventional example. Since the P<->-type base region 36 becomes shallow at the corner C where a current flows most, the injection efficiency of electrons and the transport efficiency improve, and the current amplification factor improves. The thickness of the section right below it remains unchanged, so the breakdown strength is not decreased.

Title: Three-way branch connecting part of high voltage cable
Inventor: NUMAJIRI FUMIYA
IPC: H01R4/00
Filed: 1989-12-28
Abstract: PURPOSE:To reduce the size of the offset of high voltage cables by specifying the angle at which two cables whose conductors are larger in size than those of any other cables branch off from each other, including branching of planar and three-dimensional type. CONSTITUTION:When the maximum outside diameters of cable connection terminals and the lengths of the terminals from their branching point to connection terminal outside diameter portions are D1, D2 and L1, L2, respectively, the angle at which the terminals branch off from each other is more than the expression: {tan<-1>(D1/2L1)+tan<-1>(D2/2L2)}. Therefore a branching connection unit itself has an angle and so the offset of cables connected to the unit is reduced and the distance that each cable is moved during insertion of the terminal of the cable is shortened and when cable arrangement is predetermined designing of a small manhole is possible.

Title: Efm signal multiplex high-vision video disk
Inventor: KOIZUMI TOSHIO
IPC: G11B7/24082
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the generation of moires on a screen and to suppress the deterioration in image quality by constituting the above disk in such a manner that a recording beam for exposing is oscillated laterally in a progressing direction by beam deflector and executing FM modulation with an EFM signal with this wobble frequency as the frequency to be modulated. CONSTITUTION:The FM signal subjected to the FM modulation with the EFM signal is used as a wobble signal in order to obtain the EFM signal of a specified amplitude by absorbing level fluctuations by a limiter. For example, a MUSE system high-vision signal is selected as a video signal and 13MHz is selected as a video carrier x0(t). The frequency shift of the FM is set at 3MHz. Since the band width of the MUSE signal is 8.1MHz, the lower carrier of the video FM signal x0(t) exists at 34. The carrier of the EFM signal x1(t) is set at 2.278MHz of 67.5 times the horizontal scanning frequency. The max. frequency of the EFM frequency is about 720kHz if the frequency shift of this time is selected at + or -150kHz and, therefore, the FM wave by the EFM occupies 1.41 to 3.15MHz. Then, the servo function of the high-vision video disk is not affected.

Title: Sensor
Inventor: OSADA SHINICHI
IPC: G01D3/028
Filed: 1989-12-27
Abstract: PURPOSE:To achieve stable operation even at a low voltage by connecting an active resistance between a bridge circuit and a non-inverting input terminal of an operational amplifier. CONSTITUTION:A heater temperature sensor 12, a temperature compensation temperature sensor 14, a variable resistance 22 and resistances 16, 18 form a bridge circuit 20. The circuit 20 is connected to an input side of an operational amplifier 24. A feedback transistor 28 is connected to an output side of the operational amplifier 24. Moreover, an active resistance 26 is connected between the sensor 14 and a non-inverting input terminal of the operational amplifier 24. A current is let to flow in the sensor 12 to heat the sensor. When the flow of the air comes in touch with the sensor 12 thereby to take the heat, the resistance of the sensor 12 is changed. Accordingly, the wind velocity is detected. Even if the transistor 28 is turned OFF, a voltage decrease is brought about by input bias currents IB1, IB2, and a large voltage is impressed more to the non-inverting input terminal of the operational amplifier 24 by the resistance 26 as compared with an inverting input terminal. Therefore, the operational amplifier 24 is kept active, thereby securing stable operation.

Title: Retrieving device for nesting type token train
Inventor: TAKAHASHI TSUNESUKE
IPC: H04L29/06
Filed: 1989-12-27
Abstract: PURPOSE:To improve the retrieving speed of a token train by decoding the attributes of a nest level NL, an ID code, etc., of the token train stored in a main storage for each token and retrieving the token train with use of those attributes. CONSTITUTION:The collation of attributes is carried out via a retrieving condi tion memory 106 including a request ID register and a request NL register, a header holding means 120, and an attribute comparator 115 connected to an NL output register 175. At the same time, the mismatched tokens can be skipped. When a mismatched state is detected, a length code B and 1 are added to a length code reading position A and a header address of the next token is decided by an internal address generating circuit 135. Meanwhile the code B is set at 0 when no mismatched state is detected. As a result, the body parts of mismatched tokens can be skipped at a header part. Thus the main storage access frequency for reading out the tokens matched to the retrieving conditions can be reduced down to just one to several access frequencies for reading out all token trains. Then the retrieving time of a token train is shortened.

Title: Semiconductor memory
Inventor: UCHIDA SHOZO
IPC: G11C11/417
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To hold a bus line at an intermediate potential, without allowing a through-current, which flows between a power source and the GND, to flow. SOLUTION: When a high pulse is outputted as an internal pulse signal RBEQ while a read bus line RB is in a low state, an N-type transistor(TR) N2 and a P-type TR, P2 are turned on. An N-type TR N5 also turns on. An N-type TR N3 turns off, and an N type TR N4 turns on, and P type transistors P3 and P4 also turn on. Consequently, the output of an inverter I2 goes down to a low level, a P type TR P1 turns on, and an N-type TR N1 turns off, so that the potential of the read bus line RB varies from the low level to the high level. When the signal RBEWQ is held at the low level, the P type TR P2 and N type TR N2 turn off and the read bus line RB is held at the intermediate potential level.

Title: Removing device for body hair
Inventor: IWASAKI SHIGEZAEMON
IPC: A45D26/00
Filed: 1991-12-24
Abstract: PURPOSE:To obtain the subject device reduced in irritation to the skin, can follow the irregularity of the skin and has a simple structure, by a method wherein a member to be applied to the skin, which is provided on at least one side of a body hair- removing means, is elastically supported on a main body or a frame, in order that the distance between the member and the body hair-removing means can be varied in the progressive direction of the main body. CONSTITUTION:A guide 39 is composed so that a pair of member 391 to be applied to the skin can be joined each other on both sides of a body hair-removing means. One of the members 391 acts as a skin-depressing part 392 and the other as a skin- extending part 393. In this way, irritation is lightened, and long hairs and laid hairs are raised, and thus the efficiency introducing these hairs to the clearance between a fixed catch 31B and a movable catch 32 is hightened. A pair of the member 391 each are joined to the guide 39 with a pair of elastic legs 392, and their elastic supports each are formed almost at the center between a pair of the members 391. Therefore, the members 391 can come in and out in depressed direction against the skin and can be moved in the progressive direction of a main body. As the result of it, even if the skin is accidentally pinched between the fixed catch 31B and the member 391, its shock is lightened.
