IPC: B32B5/06
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a fibrous activated carbon filter which is free from the deterioration of the functional properties of fibrous activated carbon and decreases the pressure loss, and also can be used to its best advantage almost without suffering any adverse effects due to the shrinkage deformation of a filtering medium, even at a place where the regenerating process of the carbon takes place under a steam atmosphere.

IPC: H01R33/76
Filed: 1982-08-05
Abstract: PURPOSE:To entirely eliminate improper contacts in an IC socket by opening only upper portion of a container and closing the lower portion, thereby eliminating works of coating adhesive or the like and drying it. CONSTITUTION:A container which is opened only at the upper portion and closed at the lower portion is provided on the upper surface of a housing 1, a passage 3 is partitioned by a partition wall 4 in parallel with the container 2, and a through hole which elevationally passes is opened. The container 2 contains the contact 5a of a terminal 5. The passage 3 passes the riser 5b of the terminal 5 and leads the leg 5c to the lower surface of the housing 1. In this manner, it prevents flux in case of soldering from flowing into the container 2, and the leg 5c is projected from the lower surface of the housing 1. The leg 5c is inserted into the hole Pa opened at the substrate P and both are soldered at the lower surface of the substrate P so as to connect the substrate P.

Abstract: PROBLEM TO BE SOLVED: To form a flow passage unit fixation face relatively requiring a flatness by injection molding only without using a polish process by forming a head frame by injection molding of a polymer material so that a thickness near a window becomes nearly constant. SOLUTION: A fixation part 14a for a piezoelectric element 7 of a head frame 10 is formed to have a thickness t1 nearly equal to thicknesses t2, t3 of a wall 10a forming a face 14.

Title: Optical information reproducing device
Inventor: TSUTSUI KEIICHI
IPC: G11B7/09
Filed: 1989-05-30
Abstract: PURPOSE:To accomplish the stable actuation of a semiconductor laser by outputting the last output of a driving control signal which is held in a hold output circuit part when a detected reflection returning light quantity is continuously less than a set value because there is dust or stain on the recording surface of an optical medium. CONSTITUTION:When there is dust or stain on an optical card, the reflection returning light quantity from the optical card which is detected by a photodetector 9 for an auxiliary monitor is continuously decreased, so that output voltage from a 2nd current/voltage circuit 16 is less than a hold set voltage and a hold command signal is outputted from a comparator 18. A sample-hold circuit 19 holds and outputs a voltage signal given from an amplification circuit 15 just before with the hold command signal. Such output is continued until the dust or the stain is eliminated, the reflection returning light quantity is increased and the output of the hold command signal from the comparator 18 is stopped. Therefore, a driving current for the semiconductor laser is kept constant and the output is maintained to be low even when the output of the detection signal of a photodetector 2 for monitor is lowered based on the dust or the stain. Thus, the semiconductor laser is stably actuated.

IPC: G03B3/00
Filed: 1978-11-07
Abstract: PURPOSE: To make possible stable operation of the automatic focusing device by temporarily stopping the charging operation of a strobe device during automatic focusing operation.  
     CONSTITUTION: When a release button 21 is pushed at the time when charging of a main capacitor 14 is completed, a control signal circuit 20 operates to supply a transmission stop signal to a boosting oscillation circuit 12 and at the same time, supply a distance measurement command signal to a distance measurement circuit 13. As a result, the power supply from a power source 11 to a strobe device is stopped and a distance measurement driving circuit 16 operates in response to the output signal of the distance measurement circuit 13, whereby focus is matched automatically. At the time when the focus is matched, a shutter circuit 17 is operated and a trigger circuit 18 supplies a trigger signal to a flash discharge tube circuit 15, thereby causing a flash discharge tube to emit light. When photographing is completed, a control signal circuit 20 is reset and power is supplied to the boosting oscillation circuit 12 which then resumes oscillation. In this way, stable and sure automatic focusing may be accomplished.

Filed: 1987-05-29
Abstract: PURPOSE:To reduce the size of the chip of a semiconductor IC device at the time of forming an integrated circuit, by connecting a switching element for switching to the section between the output side of an amplifier for sound recording and the input side of an amplifier for reproduction. CONSTITUTION:Since a sound signal which is amplified and outputted from a sound recording amplifier 1 is synthesized with the oscillation output for bias of an oscillator 5 for bias after they are passed through a band removing filter 4 which removes the oscillating frequency fo of the oscillator 5 only and supplied to a magnetic head 3, the frequency fo is never supplied to one end of a switching element 6 for switching at the time of recording sounds. At the time of reproduction, since the turning-on and turning-off of the switching element 6 are inverted, the oscillation output for bias outputted from the oscillator 5 is not outputted, because the switch inside the switching element 6 is turned off.
