Title: Surface treating method for external terminal of ceramic heater
Inventor: MIYATA FUMISHIGE
IPC: H05B3/02
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To surely protect an external terminal of a ceramic heater by applying nonelectrolytic plating of Ni-B to a surface of the external terminal of the ceramic heater, and then by conducting heat treatment under N2 atmosphere. SOLUTION: In a ceramic heater, a resistance heating element 3 is burried between a core material 1 and an insulating sheet 2 covering the core material 1. After a lead wire 6 comprising Ni, Co and the like is connected to an external terminal 4 comprising W and Mo, nonelectrolytic plating of Ni-B is applied to the whole of the external terminal 4 including the lead wire 6 to form a plated layer 8. A BN film 9 is formed thereafter on the surface of the layer 8 by conducting heat treatment under N2 atmosphere. Since the outermost layer of this external terminal 4 including the lead wire 6 is formed into the chemically very stable BN film 9 to coat a pin hole and a grain boundary with the BN layer 9, generation of oxidation initiated in the pin hole and the grain boundary is prevented, and especially high temperature durability is remakably improved.

IPC: H04N19/87
Filed: 1991-10-24
Abstract: PURPOSE:To encode a dynamic image by preventing the deviation of encoding errors from being generated due to the local feature between screens in real time. CONSTITUTION:When detecting a motion vector (c) for motion compensation by a motion vector detecting device 2, an inter-frame difference value (d) (vi and vj) of a block to be simultaneously obtained is supplied to an encoding amount allocation circuit 4.

Title: Automatic gain controlling method and automatic gain control circuit
Inventor: KATO HISAYA
IPC: H04L27/38
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To realize an automatic gain control, regardless of the response characteristic of an amplifier for gain control and to enable a high speed convergence. SOLUTION: A reception signal is added to an A/D converter 2A through an amplifier 1A for gain control. In an amplitude detector 3A, the size of the amplitude of the output signal of the A/D converter 2A is detected and whether the size of the amplitude is within a set range or not is detected by a comparator 4A. In the detection result of the comparator 4A, a count up is performed by a counter 5A till the size of the amplitude becomes within the set range. When the size of the amplitude becomes within the set range, the output value of the counter 5A is held in a hold circuit 6A. When the size of the amplitude becomes within the set range, a reference value is subtracted from the size of the detected amplitude by the amplitude detector 3 by a subtracter 7, the subtraction result is multiplied by a constant in a multiplier 8 A and the result is smoothened by an integrator 9A.  In an adder 10 A, the output signals of the hold circuit 6 A and the integrator 9A are added and the signals are feedbacked as control signals to the amplifier 1A for gain control through a D/A converter 11A.

CONSTITUTION:An oil chamber 7 having a pressure receiving surface 31c is formed between a vane pump 3 and the stepped part 6c of a rotating shaft 6. When the transmission torque by the vane pump 3 is increased, a multiple clutch 4 is pressed in the connecting direction by the pressing force by the pressure acting on the pressure receiving surface 31c of the vane pump 3, in addition to the multiple disk clutch 4 being pressed in the connecting direction by the pressing force by a cam mechanism 5. Thus, a high transmission torque can be provided with a small size and a light weight. Since a high torque transmission, when required, is performed through the multiple disk clutch 4, the generation of a high pressure in the vane pump 3 is not required, a small-sized one can be used as the vane pump 3, and the driving force transmitting device can be further miniaturized.

Title: Reversible refrigerant drying device
Inventor: AIYAMA MASAYUKI
IPC: F25B43/00
Filed: 1991-11-21
Abstract: PURPOSE:To simplify a freezing cycle by a method wherein two chambers are provided in a longitudinal direction of a refrigerant drying device, one chamber is provided with a spring, a drying agent and a check valve and the other chamber is provided with a drying agent and a spring, respectively. CONSTITUTION:A structure of refrigerant drying device is constructed such that a body 1 is divided into two chambers in a longitudinal direction and a cartridge type drying agent 2 is pushed by a spring 3 in an opposite direction in each of the chambers. A check valve 4 is arranged at an opposite side of the spring 3 so as to restrict a flowing direction. Due to this fact, when the refrigerant flows from the left side toward the right side, the refrigerant can flow through the lower drying agent 2 and in turn when the refrigerant flow from the right side toward the left side, the refrigerant can pass through the upper drying agent 2. That is, the refrigerant can be flowed on the same piping system from both its normal side and its reverse side and thus the refrigerant drying device can be used without using any check valve or a branch pipe even in the case that the reversible freezing cycle is being carried out.
