IPC: H03G3/20
Filed: 1993-09-07
Abstract: PURPOSE:To make an output signal level constant even when a frequency of an input signal changes. CONSTITUTION:An input signal whose level depends on its frequency is fed to an amplifier section 26 via an amplifier section 22 and a variable attenuation section 24a. An output signal from the amplifier section 26 is fed to any of band pass filters 32, 34, 36, 38 selected by a switch circuit 112 and then given to an output terminal 48. The attenuation of the variable attenuation section 24a is changed through the adjustment of variable resistors 88, 90, 92, 94, and any of variable resistors 88, 90, 92, 94 connecting in series with any conductive transistor(TR) of switching TRs 96, 98, 100, 102 is operated.

Title: Mounting construction of electronic parts
Inventor: MORI FUMIO
IPC: H01L23/12
Filed: 1985-11-05
Abstract: PURPOSE:To increase heat dissipation effect by directly installing a TAB-IC on a heat sink. CONSTITUTION:A TAB-IC 1 is directly installed on a heat sink 2 for heat dissipation with adhesives 10. The lead wire 3 of the IC 1 is glued to the wiring pattern on a polyimide insulation layer 7, i.e., a lead connection terminal 4 and is connected to an I/O pad 5. A cap 6 for sealing is glued with a polyimide insulation layer 12 in the shape of protecting the IC 1 inside the pad 5. Heat generated from the IC 1 is dissipated by the heat sink 2. In this case, the heat generated from the IC 1 is prevented to be transferred to an external equipment through the lead terminal 4 and the pad 5 since the insulation layers 7, 12 are placed between the heat sink 2 and the lead connection terminal 4 and between the lead connection terminal 4 and the cap 6 for sealing.

Title: Data compression output system
Inventor: TODA NAOHITO
IPC: G01R31/28
Filed: 1983-12-29
Abstract: PURPOSE:To reduce the output amount of data by comparing a present state value and a pre-present state value in data outputted from a circuit and extracting only state value data showing a different value to perform printing output. CONSTITUTION:Test data TD is inputted to the input terminal I of LSI1 which, in turn, outputs output data Z at every cycle of the clock pulse P from a pulse generation part 3. The data Z0 outputted from LSI1 at certain time is set to a register 7 through the contact (a) of a change-over part 5 and output data Z1 outputted at separate time is set to a register 8 through the contact (b) of said change-over part 5. In this case, a discrimination part 9 compares two contents in the registers 7, 8 and , only at the time of non-coincidence, outputs a set pulse K and outputs the data Z1 in the register 8 different from the state value prior to one clock time to paper 11 from a printig register 10 through a printer 4. As a result, the amount of output data is reduced and the number of descrimination processes in the reliability of data can be reduced.

Title: Laminating refrigerant evaporator
Inventor: YAMAUCHI YOSHIYUKI
IPC: F28D1/03
Filed: 1990-09-17
Abstract: PURPOSE:To uniformize pressure loss in a flow passage part by constructing the flow passage part formed between plates such that it is increased in a flow passage cross sectional area from an inlet tank part to an outlet tank part. CONSTITUTION:Sprayed refrigerant flows from an expansion valve through an inlet piping 51 into an inlet side tank part 5 of a laminating refrigerant evaporator 1. The inflow sprayed refrigerant flows into from an inlet part 74 into a first flow passage part 71 of a flow passage part 7. The refrigerant exchanges heat with air passing through the outside of a flow passage pipe 5 upon passing through the first flow passage part 71. For this, the refrigerant is gradually increased in the amount of a gas component (refrigerant gas) as it goes from the inlet part 74 to a communication part 73. As the amount of the refrigerant gas is increased, the refrigerant is gradually increased in its specific volume from the communication part 73 toward an outlet part 75 as in the first flow passage part 71. A second flow passage part 72 is formed by a partition wall 22 such that its flow passage cross sectional area is continuously increased from the communication part 73 toward the outlet part 75, so that the flow rate of the refrigerant flowing from the communication passage 73 to the outlet part 75 is made substantially constant even though the specific volume of the refrigerant is increased.

Title: Manufacture of semiconductor device
Inventor: SEGAWA YASUO
IPC: G02F1/1368
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device in which an irregularity in the irradiation energy of a pulsed laser is prevented, by adjusting a relationship between the size of a channel region, the pitch of the pulsed laser, and an angle which is formed by the direction in the channel width of the channel region and by a long-axis direction to be irradiated with the pulsed laser. SOLUTION: The direction of a channel region, i.e., the direction in the width W of the channel region, and the direction, i.e., the long-axis direction, of a line beam, in this case the horizontal direction, are set so as to form an angle which is decided by a specific relationship. That is to say, a relationship among a channel width W, a pulse pitch P and the angle is set so as to be expressed by a expression. As a result, even when, e.g., a defective crystallization region R is generated so as to pass the channel region, a possibility that the movement route MN of the channel region is worsened in the defective crystallization region R is reduced, parts MG's of the movement route MN evade the defective crystallization region R, it is possible to prevent the region R from being worsened, and a good element characteristic is obtained.

CONSTITUTION:A fixed amount of an undeaerated insulating oil 11 is injected into an insulating oil treating container 12 made of glass through a three-way valve 13 and deaerated with an evacuator through the three-way valve 13. At the same time a dielectric characteristic measuring container 18 for an insulating oil communicating with the container 12 with a universal tube joint 22 is made to exhaust. During the exhaustion, a stirring element 17 is rotated with an electromagnetic stirrer 16 to stir up the insulating oil. After the end of deaerating, a fixed amount of an O2-containing gas which was previously sampled into a cylinder 15 through a valve 23 is fed into the container 12 with a valve 14 opened to make the oil absorb the O2 gas with the continuation of the stirring. Then, the joint 22 is separated on the upstream side of the three-way valve 13 and the container 12 and the cylinder 15 are tilted on the joint 22 to transfer the insulating oil 11 absorbing the O2 gas to the container 18. Then, the deterioration in the oil by oxidation is measured continuously with an electrode 19 heating it with a heater 20.

Filed: 1983-12-27
Abstract: PURPOSE:To attain the double color reading in a simple constitution of a photoelectric transducer which scans and reads in lines an image formed by an optical system, by forming a stripe color filter to a transparent plate holding an original. CONSTITUTION:An output signal A of a photoelectric conversion element 18 is converted into a binary coded signal B by A/D conversion via a binary coding circuit 22. At the same time, a control clock signal phi is applied to a T-type FF34 like the transducer 18. Then a signal C showing the color correspondence of each picture element is delivered from an FF34. The signal B is turned into a signal D shifted by a bit by a D-type FF24. This signal D is applied to the input terminal of either one of AND gates 26 and 28; while the signal B is applied to the input terminal of the other AND gate. The outputs of both gates 26 and 28 are supplied to latch circuits 30 and 32. Here the phase relation is set so that a transparent part undergo the photoelectric conversion when the signal C of the FF34 is set at ''1'' with the cyan color part of a stripe filter set at ''0'', respectively. Thus black and red signals FB and FR are obtained from circuits 30 and 32, respectively.

Filed: 1987-10-01
Abstract: PURPOSE: To make it possible to absorb the unnecessary ultrasonic waves in water by adhering magnetic fluid dispersed in a solvent insoluble in the water onto a horizontal magnet. CONSTITUTION: For example, the magnetic fluid 2 is adhered at a required thickness on the surface of the planar magnet 1 and this magnet is installed on the inside wall of a water tank 3.

The magnetic flux density of the planar magnet 1, the adhesion thickness of the magnetic fluid, the viscosity of the solvent and the packing rate of the particulates are so adjusted that the loss is maximized in the desired frequency region. The planar magnet 1 is a reflection surface of ultrasonic waves. As a result, the unnecessary ultrasonic waves in the water are absorbed.
