Filed: 1985-11-22
Abstract: PURPOSE:To prevent the production of ununiform stress in a formed body and to inhibit the cracking of the formed body by adopting a two-step pressure reducing method consisting of rapid reduction from the maximum pressure to a prescribed set pressure and slow reduction from the set pressure to atmospheric pressure.

The pressure is then reduced in two steps. The pressure is rapidly reduced from the maximum pressure to >=100kg/cm<2> set pressure at >=1,000kg/ cm<2>/min reduction rate and the pressure is slowly reduced from the set pressure to atmospheric pressure at <=100kg/cm<2>/min reduction rate.

Title: Rds receiver
Inventor: NISHIYAMA YOSHINORI
IPC: H03J7/18
Filed: 1991-09-13
Abstract: PURPOSE:To realize the RDS receiver with high economy in which RDS operation is surely executed without sudden sound interrupt or a long loss of sound. CONSTITUTION:The diversity is executed in which reception electric field strength of two tuners are compared in the normal reception state and a main/ sub changeover circuit 12 selects a signal from a tuner whose electric field strength is higher. When the reception electric field strength of the main tuner is smaller than a prescribed threshold level, a broadcast station received by the main tuner is kept as it is and a signal from the main tuner is sounded. Simultaneously, the system allows the sub tuner to execute seeking in a same band and to seek the same broadcast as that received by the main tuner and the reception electric field strength is compared with that of the broadcast received by the main tuner at present. When the sought reception electric field strength is higher than the current reception electric field strength, the main tuner is tuned to the broadcast station sought by the sub tuner.

Title: Logarithmic transformer
Inventor: SUGIHARA KIYOYUKI
IPC: G06G7/24
Filed: 1989-10-11
Abstract: PURPOSE:To obtain a logarithmic transformer which is broad in its dynamic range and high in its precison by amplifying and detecting the AC component of a voltage drop at both the ends of a diode by an AC current, and taking out the DC component of the voltage drop at both ends of the diode at the time when detected voltage is kept constant as the logarithmic transformed output of an input signal. CONSTITUTION:A control current I1 is adjusted by a DC amplifier 5 so that detected output coincides with reference voltage Vr. Namely, the feedback DC current I1 is increased or decreased according to the value of input Ac voltage v1, and AC voltage v2 impressed on a diode pair D1,D2 anti-parallel-connected in the viewpoint of AC is adjusted so as to be a fixed value. Accordingly, a DC voltage drop in the diode pair D1,D2 series-connected in the viewpoint of DC is proportional to the logarithm of an AC current i2, and is proportional to the logarithm of the input AC voltage v1. Here, by using two pieces of the diodes D1,D2 anti-parallel-connected in the view point of AC, interference between an AC circuit and a DC circuit is prevented, and waveform distortion is removed, and large conversion gain is obtained. Thus, a loga rithm conversion characteristic which is broad in its dynamic range and is correct can be obtained.

Filed: 1985-11-27
Abstract: PURPOSE:To improve the output of a magnetic head by decreasing the diameter of the winding of the magnetic head and providing a tape slide guide member on the sliding surface of a magnetic tape. CONSTITUTION:The core widths of both sides of a winding window 12 of a magnetic core 11 are decreased down to a magnetic tape slide surface 11c.
