Title: Demodulator
Inventor: TAWARA MASATO
IPC: H04L27/01
Filed: 1987-06-24
Abstract: PURPOSE: To surely and quickly set an automatic equalizer circuit to a collection operating state, by using a stepped-wave generator as the signal generator which generates signals to be supplied to a carrier reproducing device.  
     CONSTITUTION: Modulated waves 101 which are distorted in waveform are inputted to an automatic equalizer circuit 1 and outputted to a demodulator 2 after the waveform distortion is equalized by the circuit 1. The output signal 107 of an asynchronism detector 3 functions as the control signal of a stepped- wave generator 5. Namely, the generator 5 generates stepped-wave signals 106 at the time of asynchronism and outputs the signals 106 to a carrier reproducing device 4. Since a fixed time area having no amplitude fluctuation is secured with respect to the time base as at Points (a) and (b) of the figure when such stepped-wave signals 106 are used, highest-level error information with high accuracy is obtained during the period and reduction of speed becomes unnecessary. Therefore, the automatic equalizer can surely and quickly execute pulling-in operations.

Title: Automobile roof sheet using high damping steel sheet
Inventor: ONO MORIAKI
IPC: B23K26/21
Filed: 1992-06-16
Abstract: PURPOSE:To faciliate bending and joining with a body frame by using a high damping steel sheet for a ceiling part, butt-welding ordinary steel with the circumference of the ceiling by laser beam welding and comprising an automobile roof sheet. CONSTITUTION:The automobile roof sheet 10 being provided with the high damping steel plate 1 for the ceiling part only, the curved surfaces are gentle, and therefore a sufficient bending may be performed. Action eliminating sound such as raindrops is performed by this damping steel sheet 1 of the ceiling part. In addition, with the use of ordinary steel sheets 2, 3 for the circumference where an extreme bending is performed, the conventional press formability for an automobile roof and the weldability with a body frame are secured. Then, there is a possibility of causing blowholes in welded joints due to a resin evaporation gas generating from the resin layer of the high damping steel plate 1 when the high damping steel plate 1 is butt-welded with the ordinary steel plates 2, 3 by the laser beam welding. Such blowholes, however, are suppressed by controlling the welding speed so that the beat width of a welded joint may be about 1/2 of the total thickness of the high damping steel plate.

Title: Liquid fuel combustor
Inventor: NAKANO OKIHIKO

Filed: 1977-12-23
Abstract: PURPOSE: To prevent engenderment of yellowish flame or soot as well as to shorten extinguishing time by augmenting blast gain to a burner more than normal combustion time prior to it instantly with interruption of feeding liquid fuel into a porous material.  
     CONSTITUTION: Air for combustion to be sent air from an air blower 9 is fed through an air feeding passage 8 into an air chamber 5. Provision of a damper 11 rotated by a rotary axle 10 at the outlet port of the air feeding passage 8 is followed by fixing an operating knob 20 at one extremity of the rotary axle 10 and a cam 21 to operate a switch 22 at the other extremity so as to be able to adjust correlative positional relationship with the damper 11.

In the meantime, since the damper 11 is set into full open condition, blast gain to a burner 1 becomes its maximum, consumption of residual fuel is done quickly, to shorten the time to the perfect combustion.

Title: Accumulator for rotary compressor
Inventor: SUGIYAMA MAKOTO
IPC: F04C29/00
Filed: 1988-06-27
Abstract: PURPOSE:To keep off any flowback as well as to make improvements in reliability by installing a retainer which partitions an inner part in having it situated at the suction port side of a rotary compressor, in an accumulator body, and forming a refrigerant passage in an upper part of the retainer. CONSTITUTION:A gas-liquid multiphase refrigerant taken into an accumulator body 2 is stored in a refrigerant inlet side space part 11, and a lower part of the refrigerant inlet side space part 11 is separated to a liquid and the upper part to gas, respectively, while the liquid is stored in the lower part of the refrigerant inlet side space part 11, and a gas portion is subjected to gas-liquid separation, while it is stored in a refrigerant outlet side space part 12 by way of a screen 14 and a hole installed in a retainer 10. Thus, the gas-liquid multiphase refrigerant is subjected to the gas-liquid separation, and the gas portion alone is inhaled in a rotary compressor 1 via an intermediate pipe 9, thus any flowback is prevented from occurring. Consequently, since locking causes such as slippage in a bearing and galling or the like in a shaft are lessened, reliability in the rotary compressor is improvable.
