Abstract: PURPOSE:To simply obtain a composite soundproof material in a gap secured state by inserting a spacer thinner than the difference of altitude between recessed and protruding parts and having a releasable surface in the recessed part at the time of adhesion to perform press bonding and subsequently removing the spacer. CONSTITUTION:At the time of compression molding, by inserting a spacer 3 thinner than the difference of altitude between recessed and protruding parts and having a releasable surface and narrower than the interval of each protruding part in each recessed part, materials are integrally laminated without collapsing the protruding part 2 at the time of compression and, further, after the finish of compression molding, the spacer 3 can be removed. Since the difference of altitude between the recessed and protruding parts of a foamed body is about 1mm, the thickness of the spacer 3 is 1mm or less, desirably, 0.5mm or less. The material is not specified: a metallic material such as stainless steel is desirable.

Filed: 1987-09-21
Abstract: PURPOSE:To prevent a deviation of an optical axis without necessitating this device to remove the rest of a gate, by forming a recessed area including the rest of the gate in a resin mold body and inserting the above body into the prescribed position of a case. CONSTITUTION:A recessed area 13 with its depth which is deeper than a height of the rest 12 of a gate is formed at the point face of a resin mold body 11 which is inserted into a case 102 and then the recessed area is molded with resin.

Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To enable a filter to be improved in assembling and manufactured at low cost while keeping effects of preventing air biting and a foreign matter from entering a pump by equipping a guide passage for preventing the air biting phenomenon of a pump onto a filter equipped for preventing a foreign matter from entering. SOLUTION: End parts of side ribs 34 are constituted so as to be brought into tightly contact with side parts of a washing tub water storage part when a pump suction filter 5 is equipped on the washing tub water storage part. Thus, a guide passage is constituted of a front rib 33, an indoor passage under part 35 and the bottom face and side faces of the washing tub water storage part and made a guide passage opening part 32 formed of the front rib 33 and the bottom face of the washing tub water storage part to make the suction force at the pump suction port concentrate only on the guide passage opening part 32.  Since the guide passage opening part 32 is equipped so as to be positioned on the bottom face of the washing water storage part in the washing tub, air is not sucked with washing water even if the level of the washing water is slightly lowered and a stable capacity of the pump and a water jet pressure from a washing nozzle can be secured.

Title: Optical signal receiver
Inventor: AKACHI SHINOBU
IPC: H04B10/67
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical signal receiver with simple configuration in which an optical signal is attenuated to have a a proper light intensity and the resulting signal is received. SOLUTION: An attenuation amt. obtained based on a transmission loss characteristics of an optical fiber and a transmission distance or the like is set to an attenuation amount setting section 12. An optical signal power variable attenuation section 13 to change freely the attenuation of the light intensity attenuates the light intensity of the optical signal received by the set attenuation amt. from the attenuation setting section 12. A photoelectric conversion section 14 receives the optical signal after attenuation and outputs the electric signal in response to the light intensity. The average power of the received optical signal is obtained and the attenuation amt. is set.  Since the attenuation amt. is set based on a transmission distance or the like, the configuration of the optical signal receiver is simplified more in comparison with the case that the average power of the received power is detected to control the attenuation amt.

Filed: 1987-09-18
Abstract: PURPOSE:To shorten the access time of a timer counter with a simple constitution by securing such a constitution where the timer counter works synchronously with a data processor by the counter clock received from a synchronizing circuit. CONSTITUTION:A synchronizing circuit 7 synchronized a basic clock CLK2 for a timer counter from an oscillator 4 by a machine clock CLK1, and supplies this synchronizing output to the counter 3 as a counter clock. Thus the counter 3 counts the counter clocks in the timing of the CLK1 and therefore works synchronously with a data processor 1. As a result, no synchronizing time is required when the processor 1 reads and writes the counter 3. Then the access time of the counter 3 is shortened.
