IPC: H04N21/647
Filed: 1995-01-26
Abstract: PURPOSE: To greatly reduce the power consumption by sending only a specific signal out to a transmission line on a transmission side through a means which converts the signal into a signal for transmission and obtaining the received signal for transmission on a reception side through a means which reconverts the signal into the original signal. CONSTITUTION: In operation mode like stand-by mode wherein an analog video signal 1 is not sent and only an analog audio signal 2 is transmitted, a power circuit 39-1 supplies electric power to an A/D converting circuit 3-2 and a P/S circuit 41 and stops supplying electric power to an A/D converting circuit 3-1, a multiplexing circuit 6, etc. At this time, a power circuit 40-1 supplies electric power to an S/P circuit 43 and a D/A converting circuit 23-2 on the reception side with a control signal 37 from a control signal generating circuit 33-2 and stops supplying electric power to an S/P circuit 18, a demultiplexing circuit 20, and a D/A converting circuit 23-1.

Title: Toothed belt
Inventor: KIMURA KAZUO
IPC: F16G1/28
Filed: 1979-02-02
Abstract: PURPOSE: To prevent exposed portions from falling off a toothed belt which is composed of tensile member wound round a toothed pulley forming mold and rubbery  elastic base material for burying the member, by pasting the exposed portions on  both sides of the belt.  
     CONSTITUTION: A tensile member 2 made of twisted rope is spirally wound round a cylindrical mold 1 for forming a toothed pulley and buried in rubbery base material 3, then the form is cut into round slices with a preset width to get toothed belts. The tensile member 2a exposed through cutting on both sides of the belt is pasted with an adhesive 4 or the exposed sides are entirely pasted with the adhesive 4. Since this simple treatment binds fibers of the tensile member 2a exposed on the cutting sides and makes the member 2a pasted to the rubbery body of the belt, the tensile member 2a does not fall of the belt.

Filed: 1984-01-24
Abstract: PURPOSE:To decrease the loss of a switch circuit by providing a circuit superimposing a prescribed voltage to a voltage applied to a load circuit connected to a switching element to decrease the drop of an output voltage. CONSTITUTION:A control signal (a) is supplied to a low voltage switching circuit 8 of the switching circuit, the circuit 8 is turned off at a zero period when the signal (a) is zero and a capacitor 11 is charged by a diode 9 and a resistor 12. When the signal (a) goes to ''1'', the circuit 8 is turned on and a voltage at a point (d) is changed so as to change the voltage at a point (e) to E+VL. Then the ''1'' level of the signal (a) is inverted (7) and fed to a gate ''0'' of the switching element 1 to increase the voltage at the point (b) to the voltage E+VL at the point (e). Then a voltage subtracting a base-emitter voltage of transistors TRs 3, 4 from the voltage E+VL is outputted to an output terminal (c). Then a collector voltage of the TRs 3, 4 is assumed as E volt to decrease the output voltage, thereby operating the circuit 8 at a desired low voltage.

Title: Time-piece
Inventor: YOSHIZAWA KEIICHI
IPC: G04B33/00
Filed: 1986-01-21
Abstract: PURPOSE:To obtain a time-piece with a two main plate structure and a low power consumption by pivotally supporting one end of a second hand shaft by an upper main plate and holding a pointer pipe coaxially fitted to the second hand shaft by a lower main plate. CONSTITUTION:The bottom end of the second hand shaft 5a of a second hand wheel 5 is pivotally supported by an upper main plate 1. The minute hand pipe 6A of a minute hand wheel 6 is rotatably fitted to the second hand shaft 5a and the hour hand pipe 7A of an hour hand wheel 7 is rotatably fitted to the minute hand pipe 6A. The engaging projection 7b of the hour hand pipe 7A engages the upper end surface of the engaging portion 2A of a lower main plate 2 and regulates the displacement of the hour wheel 7 in an axial direction together with the engagement between the upper surface of the hour wheel 7 and the lower end surface of the engaging portion 2A. Similarly, the engaging projection 6a of the minute hand pipe 6A, engaging the engaging portion 7c of the hour hand pipe 7A, regulates the displacement of the minute hand wheel 6 in an axial direction. Therefore, since the load of the minute hand wheel 6 and the hour hand wheel 7 is wholly applied to the lower main plate 2 and is not applied to the second hand wheel 5, the output of a driving motor 3 can be small even for a two main plate structure.

In this manner, an insoluble pyrophosphoric melamine pyroposphate is produced in the tissue of the wood material. After that, a soluble substance remaining in the wood material is removed, and the wood material is dried.

IPC: B65G39/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To reduce thermal stress and realize cost reduction by forming a tire disk in a ring cut by a slit which extends from an inner peripheral surface of the tire disk to an outer peripheral surface thereof and which opens slantwise with respect to the axis of a core bar in the outer periphery of the tire disk. SOLUTION: A slit type tire roller is used in an atmosphere of high temperature such as a soaking pit and is made by mounting a plurality of tire disks 13 on a core bar of internal water cooling type and by covering the outer periphery of the core bar by thermal insulator. Since the tire disk 13 has a slit 17, it is freely expanded in a peripheral direction in a usage state of high temperature atmosphere to absorb the thermal expansion by the slit 17, which can almost prevent the generation of thermal stress. The outer peripheral surface 13a of the tire disk 13 always abuts on a carried body at a part existing in the direction of thickness via the slit 17 and can ensure the continuity of the outer peripheral surface 13a of the tire disk 13 to smoothly carry the carried body.
