Title: Television receiver
Inventor: MUTO HARUO
IPC: H04N5/455
Filed: 1989-10-04
Abstract: PURPOSE:To prevent the complicated manufacture process by using a phase shift coil of an audio FM detector to adjust a filter built-in an integrated circuit. CONSTITUTION:A coil 10 connected to an IC pin leading to an audio FM detector 7 as an externally mounted coil is used to adjust the phase shift. When the phase shift is adjusted, since a mean level of a DC voltage resulting from smoothing a detected output is changed, when the DC voltage is applied to a band pass filter 6, the characteristic of the band pass filter 6 is adjusted. Thus, it is not required to provide any special adjustment means for a trap circuit 3 and the band pass filter 6 and the adjustment is implemented in common procedure as the coil 10 for phase shift adjustment. Thus, number of adjusting points in the manufacture process is decreased and the complicated manufacture process is avoided.

Abstract: PROBLEM TO BE SOLVED: To reduce current consumption, to simplify the constitution of a bias circuit and also to reduce distortion by using an FET as an amplifier and in place of a drain resistor and setting the same operating point for the FET of every stage. SOLUTION: The gates of both FET 1 of the preceding and next stages are used as the output terminals, and the LPF connected to the drain electrode of the FET 1 of the preceding stage is connected to the source electrode of the FET 1 of the next stage. Then the LPF connected to the FET 1 of the next stage is defined as a drain electrode terminal, and the drain electrode of the FET 1 of the preceding stage is connected to the source electrode of the FET 1 of the next stage via an RF choke circuit 5. Then the drain current flows to the drain electrode of the FET 1 of the next stage and then to the FET 1 of the preceding stage through the circuit 5. The drain current consumed at the drain electrode terminal is reduced down to about half of that consumed by an amplifier as long as the same distortion characteristic is secured between them.  When the number of stages of the amplifier is increased, the current consumption of the circuit 5 is reduced down to one divided by the stage number.

Title: Thermally curing device
Inventor: KIMOTO TAKESHI
IPC: B29C35/04
Filed: 1990-09-28
Abstract: PURPOSE:To prevent substrate from being oxidized and, at the same time, the substrate and chips on the substrate from being tainted by a structure wherein a controlling means of amount of exhaust gas equipped with a Venturi tube and a manometer, which control the pressure in a thermally curing chamber to be nearly equal to atmospheric pressure, in an inert gas discharging part. CONSTITUTION:Heated inert gas having the temperature and flow rate suitable for curing conditions is introduced from a gas supplying system 3. At the same time, the flow rate of exhaust gas is controlled so as to compensate the amount of the heated inert gas introduced by measuring the flow rate of tire exhaust gas flowing in a Venturi tube 7 with a manometer 10 and regulating the opening of a flow control valve 8. Thus, the heated inert gas, which is introduced through straightening vanes 3a in a thermally curing chamber 2, is lead out through exhaust passages 5b formed between the heating blocks 5a to exhaust pipes b, resulting in regulating the pressure in the thermally curing chamber to be nearly equal to atmospheric pressure. Accordingly, the oxidation of substrate P due to the intrusion of the air is prevented from occurring. Further, since no heated inert gas, which accompanies the evaporated component of adhesive, flows on the substrate P, the substrate and especially chips on the substrate can also be prevented from being tainted.

Title: Exposure method and photographic printer
Inventor: ISHIKAWA KAZUHIRO
IPC: G03B27/32
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To shorten the total processing time in exposure processing including a main exposure for each frame image of a negative film and a subexposure for an index print. SOLUTION: The order of an image exposure for the main exposure is from the frame image (40th frame image) on a cartridge side of the negative film. When the 40th frame image is arranged in the upper leftmost part, as an image arrangement for index print images, the order of them is reversed at the top and bottom and the index print images 132A are exposed line by line, so that the first exposure of the frame image (first frame image) exposed at the end at the main exposure time, at the subexposure time can be prevented. Therefore, unnecessary processing waiting is dispensed with and the exposure of the first line 134A for the subexposure can be started before the last first-frame-image exposure for the main exposure is completed.
