Title: Brazing jig
Inventor: HAYASHI TADASHI
IPC: C04B37/02
Filed: 1986-03-26
Abstract: PURPOSE:To better the operability and the characteristic at brazing time by using the ceramic sintered body having the specified porosity to a brazing jig. CONSTITUTION:The brazing jig uses the ceramic sintered body having 10-50% porosity. For this ceramic body, either ceramic sintered body of a silicon nitride, silicon carbide or boron nitride is used. The heat becomes difficult to be absorbed to the brazing jig at brazing time by improving the heat insulation by letting a pore exist on the ceramic sintered body. More heats are therefore transmitted to the solder, which becomes easy to melt and a good brazing state is obtd. The cooling speed is reduced on the substance to be joined at the cooling stage and an abrupt thermal contraction can be avoided.

IPC: G08B17/00
Filed: 1989-03-20
Abstract: PURPOSE:To secure a stable operation not to be influenced with the change of environment by updating always a prescribed level for discriminating a fire so as to meet an environmental condition, and setting it at definite physical quantity. CONSTITUTION:The mean value SLVAV of a sensor level extending over long time, for instance, one hour is always calculated, and the prescribed level for starting storage is set to be SLVAV+L by adding a constant value L to the mean value SLVAV, and the count of storage time is arranged to be started when the prescribed level is exceeded. Accordingly, since the mean value SLVAV of the sensor level for long time follows the slow change of the sensor level due to the change of the environment such as temperature, etc., the prescribed level SLVAV+L of the sum of the mean value SLVAV and the constant value L represents always the definite physical quantity. Thus, the operation becomes stable and not to be influenced by the change of the environment.

Title: Image pickup device
Inventor: SASAKI YASUSHI
IPC: H04N5/372
Filed: 1995-03-02
Abstract: PURPOSE: To switch a power supply of the device automatically by using a flicker period detection signal of a lighting light source in the system where flicker in a picked-up image is prevented by synchronizing a shutter speed with the flicker period of the light source. CONSTITUTION: The image pickup device is used under a fluorescent light for the purpose of monitoring indoor. A light receiving means 115 being a reception section of an infrared ray remote controller uses a light receiving element 109 to convert an incident light into a signal, an amplifier 110 provided with an AGC 111 amplifies the signal, the amplified signal is detected and wave- shaped and a reception signal is outputted. Since a frequency component of the fluorescent light appears in the signal from the AGC 111, a flicker detection means 116 detects it and gives frequency information of the fluorescent light to a CPU 105 of the image pickup device. The CPU 105 sets the shutter speed so as to be synchronously with the luminous frequency of the fluorescent light through a timing generator 103.  While the flicker detection means 116 detects the frequency component, the detection means 116 discriminates it that the fluorescent light is lighted and turns on a power supply for the image pickup device via a witch 118.

It is suitable the porosity of 85-95% and pore diameter of 3mm. or less, and the strength is insufficient with the porosity of 95% or more and excessive output is required with the porosity of 85% or less. Further, the directivity is bad with the pore diameter of 3mm. or more. Since the foamed body of silicate and silic alkali has no water-resistance, water-proof treatment with vinyl chloride solution, etc. coated is required.
