Abstract: PURPOSE:To detect surely collision and in a very short time by arranging random data in the preamble outputted before sending out of an effective signal from an information processing device, and thereby making it collision of different bits if signals collide on a transmission line. CONSTITUTION:An information processing device DTE is connected to a carrier band transmission line 11 through an MAU19. Beat signal level detecting system is used as collision detecting system. That is, the fact that when collision of frequency modulated data takes place on the transmission line, beat appears due to difference of data bits is utilized. The MAU19 alters format in CSM/CD system in ordinary base band, and sends out on the transmission line 11. In this format, a seed is provided in the middle of the preamble. The seed is random data made up of 32 bits. The random data are set every time data are sent out in the MAU19, and accordingly, when data collide on the transmission line 11, difference of bits occurs always, and detected as collision by detection of a bit signal. It is detected similarly by bit collating system.

IPC: H04R19/01
Filed: 1988-07-23
Abstract: PURPOSE:To take out a signal having less strain and the like by forming a capacitor between a metal vibrating body and a metallic fixed electrode, and taking out the change in metal vibrating body as the electric signal with a FET. CONSTITUTION:When a metal vibrating body 7 is vibrated, a capacitance change DELTAC occurs in a capacitor C0 formed between the metal vibrating body and a metallic fixed electrode 2. Therefore, the capacitance of the capacitor becomes C0'=C0+ or -DELTAC. Thus, a voltage change DELTAV + or -E0.DELTAC/C is obtained based on V=Q/C (Q is the electric charge in an electret). The change in capacitance becomes the change in voltage. The voltage change undergoes impedance conversion with a FET 4. The voltage change is taken out of an output terminal 4b as an electric signal. The sensitivity K0 of a sensor becomes K0 kS/g.E0 [(k) is proportional coefficient; S is an equivalent effective area formed by the metallic fixed electrode 2 and the metal vibrating body 7; (g) is an equivalent gap; and E0 is the surface potential of the electret].

Title: Automatic opening and closing device for sliding door
Inventor: KATO KENJI
IPC: B60J5/06
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent durability of an endless toothed belt from deteriorating by means of a simple constitution with a drive pulley and driven pulleys. SOLUTION: When an electric motor 31 is driven for rotation, an endless toothed belt 30 travels around driven pulleys 23, 24. By towing a sliding door 1 with a tow bracket 36 connected to the endless toothed belt 30, an opening of a vehicle body is opened or closed. The towing bracket 36, after being connected and secured to a roller support member 8, rotates together with the roller support member 8 along a curved lower rail 5. As a result, an excessive force is not exerted to the portion of the endless toothed belt 30 where the tow bracket 36 is attached. Another advantage is that, since the lower rail 5, pulleys 23-26, toothed pulleys 28, 29, the endless toothed belts 30, 34, and the electric motor 31 are made as a module and installed on the underside of a flat step panel, ease of stepping on and off is not adversely affected since the step height does not increase.

Abstract: PURPOSE:To prevent the leak of water from a vacuum destructing valve and the delay of the starting time of feeding air for destructing vacuum, by pushing- down the water in an air feeding valve for destructing vacuum which is opened into a runner upper chamber and operating the water wheel by controlling the water level always under a certain level. CONSTITUTION:When a propeller water-wheel stops the generation operation, if the opening-degree of a guide vane 2 becomes the min. or a small opening degree in the vicinity of the rated value of revolution speed of the water wheel, the water in a runner upper chamber 5 is drawn-out to a suction pipe 7 side by the pumping action of a runner 8, and the pressure in the runner upper chamber 5 lowers. Therefore, a compressed-air valve 13 connected to an air feeding pipe 9a equipped with a vacuum destructing valve 4 is opened to feed the compressed air in a tank 11 into the air feeding pipe 9a, and the water in the air feeding pipe 9a is pushed down. Then, the water level in the air feeding pipe 9a is kept lower than a certain water-level 14 in the air feeding pipe 9a by automatically controlling the opening and closing of the compressed-air valve 13 by a water- level detecting apparatus 12.

Title: Water level adjusting device in immersion hardening device for steel pipe
Inventor: OOSHIMAYA TOSHIO
IPC: C21D9/08
Filed: 1982-10-21
Abstract: PURPOSE:To make the water level in a water tank for hardening easily changeable in a short time in the stage of immersing the heated steel pipe in the cooling water in the water tank for hardening while rotating said pipe by changing the water level in the water tank according to the vertical movement of a water storage tank communicating with said tank. CONSTITUTION:A steel pipe 1 heated to a prescribed temp. is carried on revolving rolls 9 in a water tank 1 for hardening by a suitable conveyor; at the same time, the pipe 1 is rotated by the revolution of the rolls 9. The water level of the cooling water in the tank 11 is low in this stage and the cooling water is not in contact with the pipe 1. When a water storage tank 2 is moved upward by the operation of a cylinder device 12 in this stage up to the position of a broken line, the water level in the tank 11 rises up to a broken line level 20 so that the pipe 1 is thoroughly immersed in the water. High pressure cooling water is ejected from an internal cooling nozzle at the same instant when the water level rises, thereby hardening the inside and outside surfaces of the pipe. The tank 2 is lowered upon completion of the hardening to lower the water level in the tank 11, thus exposing the pipe 1 from the water surface. The hardened pipe 1 is then ejected to the outside of the tank 11.
