Title: Method and device of drawing of shape
Inventor: KANETOU OSAMI
IPC: B21C1/00
Filed: 1979-12-14
Abstract: PURPOSE: To make possible production of shapes inexpensively in mass production by inserting the end part of the material to be worked into the die of segmental dies, moving the die toward the central direction of the material to be worked while drawing to point said material then drawing the material continuously at the drawing of shapes.  
     CONSTITUTION: A horizontal press 3 set a cylinder 5 incorporated into a head 4 in the left end position and supplies the worked material to be 1 by means of quide rollers 2. The material 1 is passed in the die 10 built into segmental dies 9 from the left side, is drawn out to the right outer side and is clamped with a chuck 7. While the chuck 7 is being pulled at a low speed the segmental dies 9 are moved to the pulling side and the die 10 fixed to the segmental dies 9 move in the central direction of the material 1 thereby deforming and pointing the work. Next, the cylinder 5 of the horizontal press 3 is fixed in that position and the chuck 7 is pulled in the drawing direction at a predetermined speed, whereby the material 1 is drawn to the shape of a desired size and shape.

Title: Diode driving device
Inventor: HISHINUMA SUSUMU
IPC: H01Q3/26
Filed: 1982-09-17
Abstract: PURPOSE:To provide additionally a failure detecting function possible for checking the deteriorating state of a diode driving device, by checking an output of an AND gate so as to be at an H level at all times to the switching of an input level of a control input terminal. CONSTITUTION:A transistor (TR)8 is conductive with a control input terminal 3 applied with the H level ( +V1), and when a PIN diode 5 is normal, a reverse bias of -V2 is applied and almost no current flows to a light emitting element 23 of a photoelectric coupling element 22. Thus, a photo detector 24 is excited and an output of the element 22 goes to the H level. Thus, an AND gate 25 between an output of the element 22 and an output of an exclusive OR B21 goes to the H level. When the leak current exceeds the permissible value at the reverse bias due to the deterioration in the diode 5, the output of the AND 25 goes to an L level by setting the output of the element 22 to the L level. Thus, even if the H level is applied to a terminal 3, whether the circuit is in the normal operation or in distortion is discriminated by the H level of the output of the AND25.

Title: Controller for air conditioner
Inventor: MACHII YOSHIHIRO
IPC: F24F11/02
Filed: 1993-06-30
Abstract: PURPOSE:To prevent excess pressure of a refrigerating cycle by operating an indoor blower and an outdoor blower when a failure due to welding of a relay contact of a compressor occurs and displaying the abnormality by a display unit of an operation board, etc. CONSTITUTION:When a temperature change per predetermined time of an indoor heat exchanger 8 exceeds a predetermined value, whether the temperature change per unit time of an outdoor heat exchanger 5 is whthin a predetermined value or not is judged. When it exceeds the predetermined value, it is judged that the contact of a relay for a compressor is welded for some reaions although the air conditioner is stopped. Since it is energized through the welded contact, the compressor 2 is subsequently operated. Thus, in addition to that the pressure of a refrirgerating cycle is raised, sticking of a motor of the compressor 2 occurs to increase its damage. In this case, an outdoor blower 4 is forcedly operated, the exchanger 5 is blown by the blower 4 to be cooled thereby to suppress the pressure and temperature rise of the exchanger 5, thereby preventing excess pressure of the cycle.

Title: Synchronizing detection type amplitude detection circuit
Inventor: HASHIMOTO MASARU
IPC: H04H40/54
Filed: 1985-07-23
Abstract: PURPOSE:To decrease the variation of the detection sensitivity to an input signal to be detected by operating a transistor (TR) for amplifying the detected input signal at the class B (or class AB) operation. CONSTITUTION:The 7th and 8th TRs Q7, Q8 driven inversely in response to the detected input signal are operated respectively at class B (or class AB) operation, the current of the 7th TR Q7 changes mainly at the positive half cycle of the input signal and the current of the 8th TR Q8 changes mainly at the negative half cycle of the input signal. Since the TRs Q7, Q8 for amplifying the input signal are in the class B (or class AB) operation, the current of a current mirror type load circuit 9 is less and the offset of the synchronizing detection output terminal current due to the variation of the current mirror ratio is very small. Thus, the variation of the pilot sensitivity is very small.
