Title: Optical recording/reproducing device
Inventor: YANAGIDATE MASAHARU
IPC: G11B7/09
Filed: 1988-10-29
Abstract: PURPOSE:To always ensure the seeking and tracking control actions with high stability and high accuracy by securing the superposition at all times between the tilt correction signal of the feed mechanism of an optical pickup and the drive signal of a linear motor and controlling the drive of the linear motor. CONSTITUTION:An optical pickup 11 which radiates the recording or reproducing light beam to an optical card 1 is moved by a linear motor 12 in the direction orthogonal to the track of the card 1. This moved position of the pickup 11 is detected by a head linear scale 13, and the scale signal 14 is supplied to a tilt detecting circuit 15 and a head drive control circuit 16 respectively. In this case, the tilt correction signal which corrects the tilt of the pickup 11 in the feeding direction of its feed mechanism is always superposed on the drive signal of the motor 12 which moves the pickup 11. As a result, the force which affects the feed mechanism by the tilt of an optical recording/reproducing device is eliminated. Then the pickup 11 can be moved in an apparently horizontal state. Thus it is possible to always move the pickup 11 with high stability and high accuracy.

Abstract: PURPOSE: To prevent the falling of ballast scraped up by a rotary sweeper brush. CONSTITUTION: Ballast on the insides of rails R is scraped up by a rotary sweeper brush 5, and the ballast is guided to a conveyor 7 by a sweeping-up chute. Ballast is slid before and behind while changing the angle of the sweeping-up chute by a sliding cylinder and a tilting cylinder at that time, ballast is collected in the clearance of the rotary sweeper brush 5 and the sweeping-up chute, the sweeping-up chute is brought near to the rotary sweeper brush 5, and collected ballast is swept out onto the conveyor 7. Unnecessary ballast is discharged to the outsides of the rails R by the conveyor 7. Accordingly, the falling of ballast scraped up by the rotary sweeper brush 5 can be inhibited by the sweeping-up chute interposed between the rotary sweeper brush 5 and the conveyor 7.

Title: Automatic mixing valve
Inventor: IWAI SHIGERU
IPC: F16K35/00
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent flowing out of high-temperature water or cold water even if a temperature setting dial is suddenly rotated at a high speed by incorporating a damper for slowing down the motion of the main body part of a temperature sensor in a body. SOLUTION: A damper 7 includes a main body part 70 formed to be a ring- like disk and is integrally attached to the main body part 4a of a temperature sensor 4. A water-tight room w is formed by slide-contacting the outer peripheral part of the main body part 70 with the inner wall surface of a body 1. By reciprocating the damper 7 along the room w, water in the room w is sucked and discharged via a small diameter flow passage 72 and the motion of the damper 7 is slowed down by the flow resistance of this water. Simultaneously, the room w is contracted/expanded by the action of the damper 7 to further slow down the motion of the same. That is, the damper 7 slows down the motion of the main body 4a of the temperature sensor 4 and thereby discharging of hot water or cold water is prevented.

IPC: G06K13/063
Filed: 1989-10-20
Abstract: PURPOSE:To prevent the variation of the traveling speed of a belt due to encroachment and write and read errors to/from a magnetic card due to this variation by constituting a tooth form so as to incline in relation to the axial direction of a roller and preventing the encroachment of a guide roller to the inside of the groove of the tooth form of the roller. CONSTITUTION:The rollers 12 to 14 are provided with teeth 34, 34,.... to engage with a large number of tooth grooves 33, 33,.... formed on the inner surface of a driving belt 15 on their outer circumferential surfaces, and simultaneously, these teeth are formed so as to incline in relation to the axes of the guide rollers 28, 28,.... Namely, the tooth grooves 33, 33,.... are formed, for instance, nearly V-shaped. Accordingly, the guide rollers 28, 28,.... never encroach between the teeth of the rollers 12, 13, 14. Thus, the belt 15 is driven at nearly constant speed, and an error at the time of the read or the write of the data of the magnetic card 3 due to the unevenness of speed can be prevented.

Title: Mixture force feeding device
Inventor: KUIOKA KIYOSHI
IPC: B65G53/42
Filed: 1988-11-01
Abstract: PURPOSE:To aim at making long-distance transportation possible by providing a force feed pipe, a compressed air feeding device and an ejector connected to the mutual discharge opening of transport devices and making the diameter of the force feed pipe gradually larger toward the downstream side, thereby making piping resistance in long-distance transportation small. CONSTITUTION:The stored object of a mud feeding hopper 1 is energized from a discharge opening 3 by means of a pressure pump 4 operated by the driving of a screw conveyor 2 and is blown into a force feed pipe 5 from an air blow pipe 6a toward an ejector 6. This object is transported in the plug flow state of the lumps of the transported object and the lumps of air being alternately disposed in the force feed pipe 5. In the case of long distance, the part of the force feed pipe in the vicinity of the ejector 6 is made relatively small in its bore, and after a plug is once made, the bore is made gradually large in piping such that the bore of a force feed pipe 5a around the ejector 6 is made 150A and that of a downstream side force feed pipe 5c is made 300A. Stable long- distance transportation can be thus made possible.

Title: Fire sensor of low current consumption
Inventor: MORITA SHUNICHI
IPC: G08B17/00
Filed: 1989-10-24
Abstract: PURPOSE:To reduce an average current consumption by repeatedly stopping and restaring the supply of a synchronizing signal from an oscillating part to a signal processing part based on the signal having a prescribed period outputted from a timer. CONSTITUTION:A timer TM periodically outputs a signal in the high or low level. When the signal in the high level is outputted, a switch SW is closed and power is supplied to an oscillating part OS, and the synchronizing signal is supplied to a signal processing part PR from the oscillating part OS. The processing part PR reads in the peripheral circumstance state from a circumstance detecting part FS; and if a temperature, a smoke density, and the quantity of gas exceeding prescribed values are detected, a fire signal is sent to a receiver RE through a signal output part TX. When the fire state is not detected and the output of the timer TM goes to the low level, the switch SW is opened and the operation of the oscillating part OS is stopped. Thus, the operation of the signal processing part is repeatedly stopped and restarted by the signal of the timer to reduce the average power consumption.

Title: Operation method for ion beam device
Inventor: HARADA YASUTAKA
IPC: H01J37/08
Filed: 1987-10-30
Abstract: PURPOSE:To extend the cycles of maintenance and inspection, and reduce the capacity of a power supply by reducing plasma density when ion takeout voltage is at such a low level as incapable of focusing ion beams and increasing the plasma density when the ion takeout voltage reaches such a level as capable of focusing the ion beams. CONSTITUTION:When ion takeout voltage applied between a hot cathode 2 in a semi-enclosed vessel 1 and an external takeout electrode 4 is within such a low voltage region as not focusing ion beams 8, 9 and 10 as taken out, plasma density in the vessel 1 is reduced. And when the takeout voltage reaches such a level as focusing the ion beams 8, 9 and 10, the plasma density is increased. Almost all amounts of current flowing from the hot cathode 2 can be thereby employed as ion current. Consequently, the fouling of the electrode 4 and the inside of the vessel 1 due to sputtering upon collision of ions with the electrode 4 in a low voltage region can be lessened and the cycle of maintenance and inspection can be made longer. And the current capacity of a power supply can also be reduced.
