Title: Recording device
Inventor: TARUMI NORIYOSHI
IPC: G03G15/16
Filed: 1982-11-24
Abstract: PURPOSE:To reduce the power consumption of recording operation by providing both a rotating body for transfer and a rotating body for press contact with a heat source and a temperature detecting part, and inhibiting both heat sources from being turned on at the same time during recording operation. CONSTITUTION:The surface temperatures of the rotating body 7 for transfer and rotating body 9 for press contact are detected by detection parts 14 and 13, whose outputs are inputted to a control part 15 to control the heater 7A of the rotating body 7 for transfer and heater 9A of the rotating body 9 for press contact on the basis of the detection signals; and the heaters 7A and 9A of both rotating bodies are powered on except during transfer operation to control the surface temperature until fixation becomes possible. When, however, recording such as transfer is carried out, the heaters 7A and 9A are inhibited from being turned on at the same time, a large current resulting from concurrent power consumption for turning on an exposure lamp, etc., in a copying process does not flow.

IPC: H01L23/31
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To significantly reduce a passivation crack, by applying buffer coat material varnishes on a silicon wafer in two stages and using on the first stage a varnish having a lower viscosity than that used on the second stage. SOLUTION: On a silicon wafer having line patterns on which various recessed grooves having a width of 0.5 to 2 μm and a depth of 1 μm are formed, buffer coat material varnishes containing soluble polyimide, a polyimide resin such as a polyimide precursor, polybenzo-oxazol, a precursor thereof, and a resin such as polyquinoline are applied in two stages. In this case, on the first stage, a varnish having a lower viscosity than that used on the second stage is used. Thus, recesses and protrusions on a passivation layer can be filled with the buffer coat material, and the passivation crack can be significantly reduced.

Title: Screen printing machine
Inventor: AMAO KENJI
IPC: B41F15/08
Filed: 1986-09-02
Abstract: PURPOSE:To reduce the space between the side face of a printed matter and a printed matter support means, by a method wherein a pair of printed matter support means hold the printed matter so as to shift to be parallel to the printed matter while following the inclination of the printed matter from a printed matter feed direction by a plurality of drive means capable of shifting in a direction at right angles to the printed matter feed direction. CONSTITUTION:A sticking base 8 moves up in a direction of an arrow, and substrate support means 9 move outwards so that a substrate 7 on the sticking base 8 can move up to a screen printing position. As soon as the substrate 7 reaches to the printing position, cylinders 10 are driven so that the substrate support means 9 follow the shift of the positionally regulated substrate 7 and thereby the substrate 7 is held parallel to the substrate support means 9 with a small gap therefrom, then a screen printing is started. In this manner, the regulated printed matter and the printed matter support means can be held parallel with a small gap from each other, which enables a screen to be prevented from damaging and deteriorating.

Filed: 1994-08-31
Abstract: PURPOSE: To enable continuous reproduction without interruption with an MCPU which registers a sector outputting error detection signals as a defect sector when an error detecting means detects the error detection signal >=2 times at the same sector and executes error protection processing immediately at the time of reproducing the defect sector. CONSTITUTION: The MCPU 10 continues the continuous reproduction operation without interruption by executing reproduction retry processing and the error protection processing when the error detection signal is outputted from the error detecting means 9. The sector is registered as the defect sector in a defect register section 20 when the error detection signal 109 is detected in the same sector at least >=1 times during the reproduction retry processing, i.e., when the error detection signal 109 is outputted in the same sector >=2 times including at time of ordinary reproducing. Next, the reproduction retry processing is not executed again and the error protective processing is immediately executed to continue the reproduction operation in the case of the sector from which the error detection signal 109 is outputted and which is already registered in the defect register section 20 at the time of reproducing the defect sector again by a retry function. The sector is registered as the defect sector in the register section 20 and thereafter, the reproduction operation is continued in the case of non-registration of the sector from which the error detection signal 109 is outputted into the register section 20.

Title: Control device for automatic ventilation fan
Inventor: SAKAHARA TAKASHI
IPC: F24F7/007
Filed: 1985-09-19
Abstract: PURPOSE:To make the operation control of high accuracy simply and all the time for a ventilation fan which utilizes a detection element which senses a reducing gas and changes its resistance accordingly by absorbing the variation in the resistance value due to the variation in temperature and humidity in the environment and the variation in resistance value due to the temporal variation. CONSTITUTION:The variation in the resistance value of a detection element 1 is changed into an off-time of square wave by means of a non-stable multi-vibrator circuit 2 to become detection signal and inputted to a microcomputer 4 through a waveform shaping circuit 3. Then it receives the signal from a reference time generation circuit 5 and measures the time to take in the detection output as a reference value by the stable resistance value of the detection element 1 by means of a microcomputer 4, and after a prescribed time has passed, the detection output is once taken in as a reference value. After this, when the resistance value becomes positive with respect to the reference value with changes in temperature and humidity of the environment, changes with time, etc., reference value is renewed by taking it as a new reference value. When the reference value does not change after a certain time has passed, the reference value is forcibly reduced a little to a lower resistance value. With this arrangement changes in resistance value due to the changes in temperature and humidity of the environment and the temporal change in long term are absorbed.

Filed: 1984-10-04
Abstract: PURPOSE:To arrange a pellet fixing bed part below a lead part by a method wherein the mold setting plane of top force engaging with a lead part integrated with a pellet fixing bed part is formed protruding inward a cavity beyond the mold setting plane of bottom force. CONSTITUTION:When a part of lead frame held on the mold setting plane of bottom force 9 is pressed by the top force 8 against the bottom force for molding, a lead part 5c is pushed downward by a part 8a of top force 8 resultantly depressing a pellet fixing bed part 5a integrated with the lead part 5c below another lead part 5b. If a cavity Ca is filled with resin to be hardened in such a state, the lead parts 5c and 5b are fixed as they are resultantly forming the pellet fixing bed part 5a arranged below the lead 5b. Through these procedures, the pellet fixing bed part 5a may be arranged below the lead 5b immediately before resin sealing and forming process even if the lead frame is extremely thin film preventing any defective short-circuit between the bed part 5a and bonding wires from occurring.
