Title: Method of forming ohmic electrode
Inventor: ITOU SHIYUUZOU
IPC: H01L21/285
Filed: 1978-07-31
Abstract: PURPOSE: To make easy and certain fixing of an element to an attachement body without generating an oxidized film with a solder layer of a uniform thickness by forming an ohmic electrode by evaporating a solder to a semiconductor wafer.  
     CONSTITUTION: One of Cr, Au, and Al soluble in Si is evaporated on the rough surface 10a of an Si wafer 10 to form a first metallic layer 111, Ni wettable with solder is thereon to form a second metallic layer 112 used for a base metallic layer 11. Successively, a solder layer 12 of Pb-Sn, or Pb-Ag-Sn and others is evaporated. In this case, because of generation of various vapor pressure, an Sn(-Ag) layer 122 is formed on a Pb layer 121. An oxidization preventing layer 13 of Au or AG is formed thereon. According to such a process, the wafer is divided into various elements thereafter, it can be mounted easily and certainly on the element attachment body without causing any inclination.

Inventor: MUROTA TETSUYA
IPC: B41J2/265
Filed: 1983-05-26
Abstract: PURPOSE:To prepare a wire guide in high yield, by such a simple method that dummy wires are set at predetermined intervals in a mold frame which is, in turn, filled with a large number of anti-wear substances and, after said substances are secured by a securing agent, the dummy wires are removed. CONSTITUTION:The inner surfaces of mold frames 11, 15 are coated with a mold release agent and dummy wires (each pref. slightly thicker than a wire) 12 are set at predetermined intervals in said mold frames 11, 15. In the next step, the mold frames 11, 15 are filled with a large number of anti-wear substances each having a curved surface on at least a part of its surface, for example, steel spheres so as to contact said curved surface with each dummy wire 12 and, thereafter, a securing agent is flowed into said mold frames 11, 15.

Title: Mos dynamic memory
Inventor: FUJISHIMA KAZUYASU
IPC: G11C11/404
Filed: 1983-05-25
Abstract: PURPOSE:To increase the signal charge amount of a memory greatly without altering the structure of a cell nor using a high voltage higher than VDD as a word line signal by discharging a cell plate voltage with the word line signal, and recharging the cell plate within the time when a word line is driven selectively. CONSTITUTION:A cell plate voltage control circuit 13 includes an enhancement type p channel TR14a and an n channel TR14b of the same type. When the word line 5 selected by an X decoder 17 is driven by a word line driver 18, the rising of the terminal end 5b of the word line is delayed behind the rising of the driving terminal 5a of the word line 5, and the word line signal rises to discharge a cell plate 8 which is charged previously to the source voltage VDD. Then, the discharge of the cell plate corresponding to the waveform which delays the rising of the word line signal most is quickened. Further, the word line signal corresponding to a cell plate whose discharge is delayed rises fast and the transfer of a signal charge from the memory cell to a bit line 4 is performed at a high speed to compensate the delay of the word line signal.

Title: Agc circuit
Inventor: NAKAO KENJI
IPC: H03G3/30
Filed: 1989-04-13
Abstract: PURPOSE:To shorten an attack time when an AGC action is resumed by installing a clamping circuit and clamping a control voltage for an AGC amplifier being held by a capacitor so as not to drop less than a prescribed level from a reference voltage. CONSTITUTION:The clamping circuit 7 is connected to the capacitor 6 and the clamping voltage of the clamping circuit 7 is set to a level lower than the AGC reference voltage Vref by several +mV as the AGC function action threshold of the automatic gain control(AGC) amplifier 1. When a changeover switch 5 is turned off, namely, when a gain is held, that is when the control voltage Vc is held by the capacitor 6, the control voltage Vc does not drop less than the clamping voltage. Thus, the attack time till the automatic gain control function substantially starts operating from when the change over switch 5 is turned on is shortened.

Title: Positron ct apparatus
IPC: G01T1/161
Filed: 1992-03-19
Abstract: PURPOSE:To improve sensitivity without dropping resolution by providing a slice collimator at a border of rings with a radiation detector placed at a border for each defined number of 1 or larger. CONSTITUTION:Four rings 1R to 4R are placed cylindrically along a body axis direction of a subject (long axis Z direction of a cylinder). A plurality of radiation (for example gamma-ray) detectors 1 are provided on each ring along the ring direction. A slice collimator 2B is provided only at a border for each defined number of 1 or more, that is only between rings 1R and 2R. gamma-rays incident to the rings 1R, 2R are identified as to which ring they have been incident. The same occurs with respect to gamma-ray incident to the rings 3R, 4R. Thus a slice collimator 2B provided only between the rings 2R, 3R suppresses an increase in scattered rays, while sensitivity increases between the rings 1R, 2R and the rings 3R, 4R as there is no slice collimator. On the other hand, resolution along a Z-direction may not drop.

When a set differential pressure between the reference differential pressure and an excessive differential pressure is detected by a differential pressure detecting means, the rotary tooth 10B of the solid foreign matter crushing means 10 is rotated by the output from a control means.  The solid foreign matters collected by the fixed tooth 10A are finely crushed by the cooperation of the rotary tooth 10B and fixed tooth 10A to flow into a pump well 2, and sewage is drained by the pump 3 in the mixed state of the solid foreign matters.

Filed: 1990-04-11
Abstract: PURPOSE:To cut down a size of template model simulating working zone, without functions of a device, by reducing the number of detectors provided to a switchbox to only one. CONSTITUTION:Straight and sideward moving strokes of a fuel grab 6 attached to a refuelling machine carriage of nuclear reactor are transferred by a mechanical speed reducing mechanism and a switchbox 14 moving simulatively with the grab 6 moves on a template model 39 which scales down and simulates an actual working zone of the grab 6. Detectors 13 for halting the refuelling machine carriage are arranged to the box 14 and when the box 14 moves to outside the model, the carriage is made to half. In this case, when the number of the detectors 13 reduces to only one, the size of the box 14 can be cut down, detecting zone reduces, detection can be well done even if a whole structure is rather complicated and therewith a size of the model 39 can be cut down. Also, accompanying this, by making a controlling device store moving directions of the carriage for each function of the detector 13, moving to a direction that is the direction at just before halting when the carriage restarts, is avoided and collision against a wall and the like is also avoided.

Abstract: PURPOSE:To obtain a phase shift circuit operated by a low circuit voltage power supply by connecting three differential amplifier transistor(TR) circuits in parallel to reduce the number of TRs connected in series between a DC power supply and ground. CONSTITUTION:An output signal V6 whose amplitude is adjustable and whose phase differs from an input signal V5 by 180 deg. is obtained by 1st differential TR Q11, Q12 circuits. An output signal V7 whose phase differs from the phase of the signal V5 by 45 deg. when the frequency of the input signal V5 is an intermediate frequency is obtained by 2nd differential TR Q13, Q14 circuits. The two output signals V6, V7 are combined as vectors at 3rd differential TR Q15, Q16 to obtain an output signal V8 whose phase differs from that of the input signals V6, V7 by 90 deg.. When the input signal V5 frequency-shifts from the intermediate frequency, an output signal with a phase corresponding to it is obtained. As a result, a component located on a signal path between a power supply Vcc and ground is operated by a base-emitter voltage of a TR and a power supply Vcc (e.g. one battery of 0.9V) and then a low voltage power supply is enough for the circuit.
