Title: Liquid jet recorder
Inventor: TAKADA YOSHIHIRO
IPC: B41J2/15
Filed: 1988-05-12
Abstract: PURPOSE:To prevent the difference in recording images attributed to the difference in temperature increase between respective recording heads, by connecting two or more recording heads with each other through a connecting means having a high heat conductivity. CONSTITUTION:On a carriage 1 a recording head holder 15 shaped to be a hollow rectangle is loaded, and a plurality of recording heads 2a, 2b, 2c, 2d are connected with each other through a connecting means 16 provided within the holder 15 with a high heat conductivity and grooves 16a-16d for setting the recording heads. Therefore, if only one recording head 2a from among the two or more recording heads 2a-2d is used for recording, there is no possibility that only the recording head 2a used for recording is subjected to temperature rise due to the heat accompanied by the recording. The generated heat is transferred to the other recording heads 2b-2d unused for the recording through the high-heat conductive connecting means 16, whereby the temperatures of the respective recording heads 2a-2d can be constantly kept uniform. In this manner, the difference in recording density in the recording heads 2a-2d and the difference between recording images such as a change in recording color balance are eliminated.

Title: Formation of polyimide film for lead frame
Inventor: NOSE KOJI
IPC: H01L23/50
Filed: 1989-05-06
Abstract: PURPOSE:To obtain a film-forming method, by which a resin-sealed package having no possibility of the generation of failure due to moisture absorption can be obtained, for a lead frame by a method wherein a liquid polyimide resin flows into the cavity of a film-forming mold, the lead frame is set thereon and the polyimide resin is cured by heating. CONSTITUTION:A liquid polyimide resin 3 flows into a cavity 6 of a film- forming mold 4, a lead frame 1 is set thereon in such a way that the rear of a die pad 2 comes into contact to the upper part of the above resin 3 and the resin 3 is cured by heating to form a polyimide film. For example, a resin tetrafluoride having a water repellancy is formed as the material for the above mold 4 so as not to stop a mold release of the mold 4 from a polyimide resin 3. Thereby, a polyimide film of a uniform film thickness can be formed on the rear of a die pad and a residual stress in the film becomes small and at the same time, a sealing resin is closely adhered to the rear of the die pad through the polyimide film, the dispersion and relaxation of shearing, compression and a tension stress, which are generated between the die pad and the sealing resin, can be realized and the peeling of the lead frame is prevented.

Title: Thermoforming apparatus for thermoplastic resin sheet and thermoforming method therefor
Inventor: KUBO MASAHIRO
IPC: B29C51/10
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for forming a thermoplastic resin sheet that can solve drawdown, low shot cycles, raindrops, and lowering of transparency. SOLUTION: A resin sheet 1 being in press contact with a belt 40 is formed in accordance with the rotation of the belt 40, thereby preventing drawdown and improving shot cycles. Also, upon heat formation, the resin sheet 1 is placed in press contact with the belt 40, so that air never comes in between the belt 40 and the resin sheet 1 to thus prevent the occurrence of raindrops, and by making the surface of the belt 40 into a specular surface, fine transparency can be given to the resin sheet 1.

Title: Digital-analog converter
Inventor: KUSAKABE MIZUO
IPC: H03M1/80
Filed: 1982-06-29
Abstract: PURPOSE:To reduce the pattern area to about a half in comparison with that of a conventional similar D/A converter, by operating an output voltage level shift circuit using an insulation gate field effect transitor(TR) as a constant current source. CONSTITUTION:A voltage VO2 of an output terminal O2 of the D/A converter circuit is converted linearly into VI-VDD corresponding to digital inputs a10- a1. The resistance value of a resistor 60 is selected to a value biasing the voltage VO2 to (VDD+V1/2) when the digital input is a digital quantity 0. E-n-MOSTs 31-40 operate at the saturating region as the constant current sources. An output voltage level shift circuit 70 controls a gate voltage VGS when the E-n- MOSTs 31-40 being the constant current source are selected by the digital inputs a10-a1. Thus, the pattern area is reduced by the area of the depletion TRs in comparison with a conventional D/A converter, and even if the number of bits of digital inputs ai is increased, the pattern area is reduced to about a half.
