Title: Zooming operation device for television camera
Inventor: KATO HIROSHI
IPC: G02B7/08
Filed: 1995-02-17
Abstract: PURPOSE: To vary frictional resistance force generated between a friction plate and a fixing plate in accordance with the load fluctuation of a cam barrel, to apply a load of the frictional resistance force to the cam barrel with a resistance transmitting member and to remove the load fluctuation of the cam barrel by varying energizing force by an energizing member with a cam member, linked with the rotational extent of the cam barrel. CONSTITUTION: When a zooming operation is executed, the rotational force of a zooming cam barrel 36 is transmitted to the rotary shaft 86 of a load fluctuation removing device 80, to rotate the rotary shaft 86 and a moving member 96 starts to move along the cam surface 104 of the cam member 94 by the energizing force of a spring 98. Therefore, the elasticity of the spring 98 is varied and the energizing force corresponding to the elasticity is imparted to a pressing plate 100 and the friction plate 102. Thus, the frictional resistance force generated between the pressing plate 100 and the friction plate 102 is varied in accordance with the elasticity of the spring 98 and the zoom cam barrel 36 is loaded with the frictional resistance force generated at this time with the rotary shaft 86. The resistance characteristic of the frictional resistance force is gradually made small from a wide end to a prescribed zoom ratio at the time of the zooming operation and when the resistance characteristic exceeds the zoom ratio, the resistance characteristic suddenly becomes great, so that the load fluctuation of the zooming cam barrel 36 is removed.

Title: Expandable antenna reflection mirror
Inventor: NODA TAKAHIKO
IPC: H01Q15/20
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To perform expansion with high reliability without entangling a cable with a movable hook by providing an entanglement prevention mechanism for covering the movable hook after a separation part is separated. SOLUTION: This expandable antenna reflection mirror is mounted to a launcher in a housed state and is expanded to a larger diameter by expanding an arm 1 in the direction of an arrow with an expansion hinge 2 as a supporting point after being launched onto a track. In expansion, by releasing a holding structure 3 holding a metal mesh for constituting a mirror surface and the cable at the time of launching by a holding release mechanism 5 as a first stage and expanding the holding structure 3, the metal mesh and the cable can be freely moved around. The movable hook 10 is exposed by separating the separation part 6 from the holding release mechanism 5 and the entanglement prevention mechanism 11 covers the movable hook 10. As a result, the freely movable cable is expanded to a final tension state without being entangled with the movable hook 10.

Title: Memory unit
Inventor: WATANABE TOSHIKATSU
IPC: G06F12/16
Filed: 1979-03-14
Abstract: PURPOSE: To make it possible to omit complicated operations even for change of  memory contents in the data side, by using a memory element for error signal consisting of a RAM and by writing an error code to perform check.  
     CONSTITUTION: When power is supplied, data processing part 25 reads out only data of data storing memory elements 23-1W23-n, and sends it to the memory unit 21 side. At this time, check circuit 26 generates a parity bit according to this data and sends it to the unit 21 side. The unit 21 side writes only the parity bit out of transmitted data and the parity bit onto memory elements 24-1W24-n for error signal consisting of RAMs. After generation and write of the parity bit for all memory addresses, the control is transferred to the actual program to detect a parity error in circuit 26. As a result, even for change of memory contents in the data side, it is sufficient if data is read and the error code corresponding to this data is written.

Abstract: PURPOSE:To control correctly a light emitting light quantity by controlling selectively a charging loop of plural capacitors connected in parallel to the spare discharging tube in response to a light emitting irradiating angle variable action by a light emitting irradiating angle variable constitution by means of the control means. CONSTITUTION:At the time of a wide angle, the first and second change-over switches 12 and 9 of a control means 11 and a discharging means 5 are both changed over and connected to contacts 12a and 9a. Consequently, the supply through the first change-over switch 12 of a low voltage supplied to a terminal Z is not executed, and a discharging resistance 10 is directly connected through the second change-over switch to the second capacitor 3 and in parallel connected through the third diode to the third capacitor 4. Consequently, transistors 13 and 14 are not in the conducting condition. For this reason, The capacitor, which is supplied to a terminal X and charged by a high voltage, is the first capacitor 2 only, and the energy, which a spare discharging tube 1 consumes by the action of a trigger circuit B, goes to be the charging charge of the first capacitor 2 only.

Title: Detection method for record eccentricity
Inventor: MEGURO HIROSHI
IPC: G11B33/10
Filed: 1984-02-22
Abstract: PURPOSE:To attain more accurately the detection of the eccentricity of a record despite a large oval deformation is present by developing the eccentric degree related to the revolving angle of the record to a Fourier series to detect the peak value of a term having a period equivalent to the revolution of the record and also detecting the record eccentric position from a phase constant. CONSTITUTION:Each level of the electric signals V outputted from photoelectric devices 6a and 7a is set in response to each oscillating angle of an arm 5. The signal V is considered as the one added with a sine wave signal shown by a dotted line. Then the signal V is sampled by a control circuit 9 at a proper time interval and synchronously with detection for rotary angle position of a turntable and undergoes the A/D conversion. The A/D converted digital data are collected in a period equivalent to a revolution of the turntable and used for calculation. Thus a component equivalent to a curve shown by a dotted line is extracted by the development of a Fourier series. Thus it is possible to detect accurately both the degree and position of the record eccentricity in any case.
