Title: Glow discharge heat treatment apparatus
Inventor: KANEKO TOMOAKI
IPC: C21D1/09
Filed: 1980-08-16
Abstract: PURPOSE:To carry out stable nitriding or carburizing treatment over a long period of time, in applying treatment such as ion nitriding, ion carburizing or the like to an object to be treated by glow discharge, by adjusting the object to be treated to earth potential and, if necessary, heating the same. CONSTITUTION:Objects 4a-4d to be treated are placed on plural steps of shelves 3a-3d provided to an electroconductive cylinder 2 in a steel vacuum container 1. An interior of the container 1 is evacuated to 0.2-20 torr by a vacuum pump 9 and a nitriding or carburizing atmospheric gas is introduced from a bomb 11. Subsequently, from a D.C. high voltage power source 7, voltage of several hundreds- several thousands volt is applied between an anode 5 and the container held at earth potential, that is, the objects 4a-4d to be treated and the atmospheric gas is ionized by glow discharge to subject said objects to be treated to ion nitriding or ion carburizing treatment. In this time, the temp. of the objects to be treated detected by a  thermocouple 14 is applied to a control circuit 16 to control voltage of the power  source 7 and a heater power source 13. Stable treatment can be carried out at high  heat efficiency.

Title: Electric carpet
Inventor: EBIHARA HIROSHI
IPC: H05B3/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce a non-slip resin amount and to prevent the occurrence of a back material by a method wherein a back material having a cord heater arranged in a zigzagging state between a surface material and the back material is formed on the opposite surface to the cord heater by using a fiber felt coated with nonslip resin of acrylic ester copolymer latex. SOLUTION: An electric carpet incorporates a cord heater 3 and a cord sensor 4 between a surface material 1 being woven cloth made of polyester and a back material 5 being woven cloth made of polyester. The surface opposite to the cord heater side of the back material 5 is impregnated with acrylic ester copolymer latex 2, being nonslip resin diluted by a moisture content, by a thickness of approximate 1/3 of the thickness of the back material. Impregnated acrylic ester copolymer latex enters between single fibers of which non- woven cloth is formed to form a latex elementary surface. This constitution, when a load is exerted on the electric carpet, prevents unnatural movement of the electric carpet by means of the latex elementary surface of the back material 5.

Title: Semiconductor device and manufacture thereof
Inventor: ITOU KAZUO
IPC: H01L27/092
Filed: 1984-06-04
Abstract: PURPOSE:To produce a semiconductor device at low cost making operation easier by a method wherein a latch up phenomenon by a parasitic transistor is prevented from generating without fail. CONSTITUTION:The concentration of P type impurity in P<+> buried layer 12 is made higher since the phosphorus ion implanting concentration of P<+> buried layer 12 may be preliminarily adjusted freely. The resistance Rw' between base and emitter of parasitic TRQ2' (current is easy to flow through the intermediary of a P<+> buried layer 12 while the resistance in P<-> rising up layer 14 may be neglected in comparison with the resistance Rw of P<+> buried layer 12 since the distance in the longitudinal direction is extremely shorter than that in the lateral direction) may be reduced lower than normal Rw so that the parasitic TRQ2' may hardly enter an active region to prevent the parasitic TRQ2' from starting operation. Through these procedures, a parasitic thyristor may be prevented from turning ON to avoid a latch up phenomenon without fail.

Title: Absorbing device of unnecessary radio wave
Inventor: HISADA OSAMU
IPC: H01Q15/24
Filed: 1982-06-30
Abstract: PURPOSE:To reduce the loss of a main polarized wave, to increase the return loss of an unnecessary cross polarized wave, and to obtain sufficient absorption effect by devising the shape of a resistor constituting a resistance plate as a radio wave absorber provided in a cylindrical waveguide. CONSTITUTION:The resistance plate 7 consisting of a resistor 6 with plural, e.g. two tapered parts 6a and 6b which projects in an input direction in a propagation direction is arranged in the cylindrical waveguide 5 in parallel to an electric field component E. This resistance plate 7 is formed by vapor-depositing the resistor 6 consisting of nichrome on a flat plate of, for example, mica 8 and grinding the resistor 6 in a shape shown in a figure. The resistor 6 is ground easily, so it is formed in any shape. Then, the two tapered parts 6a and 6b are equalized in acuteness and almost no resistor 6 is left at the center position of the cylindrical waveguide 5. Thus, plural tapered parts are provided and almost no resistor is left where the intensity of the electric field in the cylindrical waveguide is maximum, reducing the loss of the main polarized wave. Then the tapered parts increase in acuteness without making the resistor longer in the propagation direction, so the return loss of the unnecessary cross polarized wave is increased.

Title: Direction adjustment use display device for satellite signal reception antenna
Inventor: MATSUBARA HIROSHI
IPC: H01Q3/02
Filed: 1993-04-16
Abstract: PURPOSE:To provide a display device by which a correct and good reception direction is clearly identified even in either of a high level area and a low level area by providing a detection circuit, a peak hold circuit, a comparator circuit and an indication device to the display device. CONSTITUTION:A satellite signal is detected by a detection circuit 20 and a peak hold circuit 21 receiving part of the signal always provides the output of a peak hold level up to now. Since two input levels given to a comparator circuit 22 differ from each other when the level of the satellite signal rises at first and then decreases and the level exceeds its maximum level by changing the direction of an antenna unidirectionally, a display state of an indication device 23 changes. When the level of the satellite signal rises at first and then decreases again by reversing the direction of the antenna, the display state of the indication device 23 restores only at a maximized level and the display state changes again after the maximum level point. Thus, a good reception direction is clearly grasped by matching the direction of the antenna with a direction at which the display state is restored.

Title: Parallel synchronous operation controller
Inventor: TAKI KENICHI
IPC: G06F1/04
Filed: 1982-06-30
Abstract: PURPOSE:To hold synchronism securely, by dividing the frequency of an input clock signal through plural microcomputers and putting one computer in frequency dividing operation synchronously with the timing of the frequency-divided signal generation of the other specific computer. CONSTITUTION:The clock signal CK of an oscillator 4 is inputted to terminals ia and -ia of the processor 2a of a specific computer 1a to output a frequency- divided signal Cm. When the frequency-divided signals Cm and Cs of processors 2a and 2b are both at ''0'', an ENR6 generates an output with a level ''1''. An FF7 is triggered by a leading edge of the CK and its output goes up to ''1''; and the CK is inputted to the terminals ia and -ia of the processor 2b through an AND8 to start outputting a frequency-divided signal Cs. Inputs to the ENR6 go up and down to ''1'' and ''0'' and its output goes down to ''0'' to cut off the signals to the processor 2b. When the CK goes down to ''0'', the ENR6 generates the output again and the gate 7 also generates the output. Thus, the timing of frequency-divided signal formation is made coincident and the synchronism is held securely.

Also, the set signal 24 is inputted to a subtractor 8, calculates a difference between said signal and a detection signal 29 from the engine 1, detected by a rotary detector 7, and is inputted to a proportional element 10 of a control part 30. The control part 30 adds an output 27 of the proportional element 10, and a signal outputted from a differentiator 12 through said proportional element 10 by an adder 23, and sends an operation signal 31 corresponding to a rotary deviation 32, to a fuel injection pump 3. When the switches 22, 23 are changed over as a broken line in the figure after the engine 1 has attained to about 90% of the rating rotary speed, an output signal 25a of the integrator 11, which has attained to a set rotary speed level is applied to an adder 13.
