Filed: 1987-05-15
Abstract: PURPOSE:To obtain an optical head having a long bearing life by providing a moving part including an objective lens, a same slide bearing, a bias coil to float the moving part and a magnetism generating member. CONSTITUTION:The dead weight of a moving part 20 including an objective lens 22 to record and reproduce information to a disk and a reaction force of a plate spring 36 by the focus off-setting of the moving part 20a are operated as a bearing pressure between a slide bearing 32 and a guide shaft 44. The pressure is cancelled by an electromagnetic force to occur at a bias coil 40, a bearing loss is decreased and a bearing can be made into the long life. The magnetism generating member to generate an electromagnetic force at the bias coil 40 is commonly used with a magnet 45 to generate a driving force at a focus coil 24 and a tracking coil 26, the magnetic flux to leak from a main magnetic circuit for coils 24 and 26 is focused by a sub-magnetic circuit, supplied to the bias coil 40 and the use efficiency of the magnet 45 can be increased.

Abstract: PURPOSE:To extend remarkably a synchronism pull-in range, by providing an orthogonal phase detector, a multiplying circuit, a delay circuit, a multiplier, a voltage controlled oscillator and the like for operating the AFC function. CONSTITUTION:An input signal is inputted to the orthogonal phase detector 1. Two outputs P, Q of the detector 1 are inputted to the multiplying circuit 2 and the output P is inputted to the multiplier 4 via the delay circuit 3 and multiplied 4 with the signal Q. The output of the circuits 2, 4 is inputted respectively to the voltage controlled oscillator 7 via LPFs 5, 6, and the output is led to the detector 1. Since an error signal of number of waves of (1/2) sinomegatau is obtained at the output of the LPF6, when the output is taken as the control signal of the oscillator 7, the loop is operated so as to zero (1/2)sinomegat and the AFC loop is formed. When the frequency difference omega comes to the vicinity of zero, the phase locked circuit is operated for bringing the system into the synchronism state.

Filed: 1984-06-13
Abstract: PURPOSE:To prevent erroeous operation due to a side-lobe, by detecting a part of the receiving signal of ultrasonic transmitter-receivers on the circumference of a circle. CONSTITUTION:Reflected ultrasonic receiving signals from an object by transmitter-receivers 4-1-4-n arranged on the circumference of a circle are selected by a selective amplifier 5 and detected by a rectifier circuit 6 while detection output equal to or more than a threshold value through a level discriminator 8 and a delay circuit 9 is supplied to an AND circuit 10 and the counting stoppage of a counter 18 starting counting in a delay circuit 9' after a predetermined time was elapsed from the transmission point of time is controlled to measure a distance. Pulses having widths corresponding to the time difference between receiving outputs equal to or more than the threshold value from transmitter-receivers 4-p, 4-r, 4-s, 4-q, left, right, above and below to the center of a circle are outputted from wave form shaping circuits 15-1, 15-2 and, when the time difference is smaller than the delay time of the circuit 9', a gate 10 is opened by a pulse width discrimination circuit 17. By this mechanism, the generation of erroneous operation due to a side-lobe is prevented and the enhancement in the resolving power to a measuring object can be achieved.

Title: Communication system
Inventor: KATO NORIYASU
IPC: H04L12/46
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a communication system which saves addresses, effectively uses them, reduces server's burdens and communicate in the middle of connector moving even when a portable terminal goes out of a base station to which an address is allocated. SOLUTION: This communication network consists of a DSA server 1 that has a subnet address management table 21 and an MSR 3 (client) that has a table 31 which manages an address and a net mask. With this, when the client needs a subnet address, the DSA server 2 gives the subnet address and a net mask, and when it does not need it any more, it releases the subnet address and the net mask. Therefore, an address is saved and effectively used, and on the other hand, server's burdens are reduced. At the same time, even when a portable radio terminal goes out of a base station to which the address is allocated, it is possible to continue communication in the middle of moving.

Title: Developing device for electrostatic latent image
Inventor: YAMAMOTO HAJIME
IPC: G03G15/08
Filed: 1985-06-03
Abstract: PURPOSE:To perform contactless development and to obtain high resolution by arranging a toner carrier body opposite while leaving a gap so that a photosensitive body does not contact toner on the toner carrier body, and applying a voltage between a linear electrode and a conductive base body and causing gas discharge. CONSTITUTION:When thetoner carrying roller is put closer to an electrostatic latent image carrier body 9 which has the conductive base 8 on the back surface, the electric field established between the linear electrode applied with a high AC voltage and the grounded conductive base increases in internsity gradually and exceeds the dielectric strength of air, specially, at the edge part of the linear electrode to cause gas discharge. When the gas discharge is caused from the linear electrode, the toner nearby the discharge part is scattered in the gap between the toner carrier roller and electrostatic latent image carrier to stick onto an electrostatic latent image. In general, when the image is developed while the electrostatic latent image carrier and the toner layer on the toner carrier roller are not in contact with each other, the image density decreases and image lines narrow down, but the toner is scattered forcibly by the gas discharge to come much closer to the electrostatic latent image, so an image having sufficient image density and image line width is obtained. Consequently, the toner image with superior resolution is obtained.

Abstract: PURPOSE:To operate an oil injection device without fail in a place where only a heat source exists by attaching a flexible pipe to the tip opening part of a heat pipe provided with a refrigerant fluid therein and allowing the tip of this flexible pipe to make close contact with a metering piston. CONSTITUTION:Bellows-shaped flexible pipe 304 is attached to the tip opening part of a heat pipe 302 provided with a refrigerant fluid 302a therein, and the tip of this flexible pipe 304 is allowed to make close contact with a metering piston 307 positioned by means of a return spring 305. When heating a part 301 of the heat pipe 302 to be heated, the refrigerant fluid 302a is evaporated to permit the flexible pipe 302 to be elongated, allowing the metering piston 307 to be forced in. When cooling a part of the heat pipe 302 to be cooled, pressure within the heat pipe 302 is reduced to permit the metering piston 307 to return to its original position. Accordingly, it is possible to operate an oil injection device without fail in a place where only a heat source exists.
