Abstract: PURPOSE:To enable miniaturization and cost reduction of an optical head actuator by a construction wherein a pair of rubber dampers so shaped as to get beyond a linear region when they stretch are fitted so that one of them stretches when the other shrinks. CONSTITUTION:Rubber dampers 9a and 9b for returning an objective lens 1 to a prescribed position are provided. The rubber dampers 9a and 9b are so shaped as to get beyond a linear region when they stretch, and joined by rubber damper retaining pins 7a, 7b, 8a and 8b to a movable element constructed of the objective lens 1, an objective lens holder 2, a bearing 3, a balancer 4, a coil 6 for focusing control and a coil 5 for tracking control and to a yoke base 10 so that one of them stretches when the other shrinks, when the objective lens holder 2 rotates in the direction vertical to the optical axis. By fitting the rubber dampers 9a and 9b so that one of them stretches when the other shrinks, in this way, the linear region can be expanded. According to this constitution, the rubber dampers 9a and 9b can be made small in size and miniaturization and cost reduction of an optical head actuator are enabled.

IPC: H01H50/10
Filed: 1989-12-28
Abstract: PURPOSE:To reduce the impedance of a reed relay of coaxial structure using a glass pipe by disposing a plurality of nonmagnetic pipes on the outside of the glass tube in a determined pattern. CONSTITUTION:Magnetic relays 2, 3 having opening and closing contact parts 4 are disposed in the axial direction of a glass pipe 1, and metal pipes 6, 8, 9 having different diameters are coaxially disposed on the outside thereof. Insulating bodies 10, 10 are interposed between the metal pipes 6 and 8 and between 8 and 9, respectively. The metal pipes 6, 9 are connected to each other through a cable 11 and grounded. The metal pipe 8 is bonded to one magnetic reed 3 through a cable 12. Hence, relatively large electrostatic capacitance is formed between the metal pipes 6 and 8 and between 8 and 9. Thus, the electrostatic capacitance between the signal line and the ground is increased, and the value of the impedance of the reed relay is reduced.

IPC: H04N5/44
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to provide an accessory program for promoting the program explanation or purchase of an original program by displaying a sub-stream having depending relation with a main stream while suppressing the normal observation of the main stream when the main stream included in inter-stream depending relation information is not purchased. SOLUTION: A separation part 23 separates a main stream from a broadcasting stream to send it to a video/sound reproducing part 25 and separates a sub-stream to send it to a data processing part 26. Since the reproducing part 25 can not reproduce the scrambled main stream, an output for the scrambled main stream from the reproducing part 25 is void and only video/sound signals for an accessory program are outputted from the reproducing part 25 at normal time and only the accessory program is provided to viewers. When a purchase stream is specified, a release instruction is outputted to a scramble releasing part 22, so that the program can be normally viewed.

Title: Depositing apparatus of liquid-drop
Inventor: ARAN JIYON MAIKERUZU
IPC: B41J2/04
Filed: 1989-12-28
Abstract: PURPOSE: To reduce a pressure crosstalk effect by disposing an array of grooves so that one of grooves of another group exists between two of the grooves selected when a liquid droplet is discharged from the selected groove of the one group. CONSTITUTION: A flow of N-bit data decides a selection of an operation of one groove of a group in one cycle of a waveform applied by a signal generator 14, and decides a selection of an operation of the other groove of a group in next cycle of the waveform. Thereafter, the flow of N-bit data selects a groove of a group to be operated before appearance of a next pulse line 128 to thereby operate the groove selected when the pulse appears, thereby discharging a liquid droplet. In this printing operation, the groove selected for printing has at least one nonoperating groove at its opposite side, and hence generation of a crosstalk of a certain density of the grooves is substantially reduced.  If the grooves are arranged in three groups, at least two non-operating grooves exist on surfaces of the grooves, and generation of the crosstalk of the groove of the specific density is further reduced.

IPC: B60T17/02
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To control the operation and the stop of a negative pressure pump always to the optimum regardless of the change of the atmospheric pressure. SOLUTION: When the atmospheric pressure Pa is equal to or more than a predetermined value Pa0 , a negative pressure pump is operated when the relative pressure ΔPb between the atmospheric pressure Pa and the absolute pressure Pb in a tank becomes less than a threshold value δPbON, and the negative pressure pump is stopped when the relative pressure ΔPb becomes equal to or more than a threshold value ΔPbOFF, thereby preventing the occurrence of energy loss resulting from the unnecessary increase of the relative pressure ΔPb.  When the atmospheric pressure Pa is less than the predetermined value Pa0 , the negative pressure pump is operated when the absolute pressure Pb in the tank becomes equal to or more than the threshold value PbOFF, and the negative pressure pump is stopped when the absolute pressure Pb in the tank becomes less than the threshold value PbOFF, thereby securing the relative pressure ΔPb as large as possible while preventing the negative pressure pump from becoming continuous running state.
