IPC: H05H7/14
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To bring down and insulate the heat from a vacuum cavity part effectively by installing cooling water pipes and long heat-insulating holes around the vacuum cavity part in a cylinder part, making cooling water flow in the cooling water pipes, and either filling a medium having thermal conductivity smaller than that of the cylinder in the long heat-insulating holes or maintaining the insides of the long heat-insulating holes in a vacuum condition. SOLUTION: A cylinder 1 of a vacuum chamber A is composed of a thick wall and generally cylindrical body formed from an insulating non-magnetic material and is provided with a vacuum cavity part 2 to pass particles and a thin layer 4 formed from a conductive non-magnetic material in its inside. Cooling water pipes 3 and long heat-insulating holes 5 are alternately formed in the lengthwise direction of the cylinder 1. The long heat-insulating holes 5 act as shields against heat flow by either filling a medium having thermal conductivity smaller than that of the material of the cylinder 1 in the long heat-insulating holes 5 or maintaining the insides of them in a vacuum condition.  Thereby, heat generated in the vacuum cavity part 2 is collected in the vicinity of the cooling water pipes 3 by the action of the long heat-insulating holes 5 and thus, the cooling efficiency by the cooling water pipes 3 can be enhanced.

Abstract: PURPOSE:To shorten the time of ghost elimination and realize simplified, low- cost constitution by providing a memory stored with only data on gains and positions of plural selected taps for every channel. CONSTITUTION:A video signal of every reception channel inputted to a terminal 1 is inputted to a transversal filter 2 and a subtracter 3, and supplied to the differential device 4a of a ghost detecting circuit 4. The difference signal of the difference device 4a is A/D-converted (4b) and then a cyclic integrating circuit 4c reduces its noise to apply the resulting signal to a correlator 4d. The output of the subtracter 3, on the other hand, is inputted to a comparator 4e, which compares it with a reference signal of ghost detection to output a ghost information signal to the correlator 4d. The correlator 4d operates the correlative function between said two signals to detect the time position and amplitude of a ghost component, determining the gain of each tap of the transversal filter 2.

Title: Back tension device
Inventor: KOTABE HIROSHI
IPC: B65H23/06
Filed: 1984-04-27
Abstract: PURPOSE:To secure the stable drive of a tape by using a part of a back tension controller which controls a supply reel drive disk in a normal record/reproduction mode and applying the back tension of a prescribed level different from that of the record/reproduction mode also in a tape quick traversing mode. CONSTITUTION:A hook pin 17 of an L-shaped arm 5 is pressed by a counterclockwise turn of a normal feed lever 16, and the arm 5 is turned in the direction where a band brake 3 is pulled to perform a normal tape feed action. While a quick traversing plunger 25 attracts a quick traversing lever 20 to slide it to the right, and a quick traversing lever 19b is turned counterclockwise. Then a comparatively small revolving power of counterclockwise is applied to a quick traversing lever 19a of the other side via a compartively weak spring 30. This revolving power gives a comparatively small tension power to the brake 3 through the pin 17. Thus a supply reel drive disk 2 is damped with a comparatively small power, and therefore a supply tape 21 obtains the back tension suited to the quick traversing.

Title: Frequency-voltage converter
Inventor: SAKAI HIDEYUKI
IPC: G01R23/10
Filed: 1982-05-21
Abstract: PURPOSE:To enable the conversion of an input frequency signal to an analog voltage signal at a high accuracy by setting a clock pulse frequency at a higher level than an input frequency while a counter memory is provided with a sufficiently large memory capacity. CONSTITUTION:An input frequency signal applied to an input signal terminal 1 is converted into a square wave at each positive half-cycle with an FF 2. With the output of the FF 2 as control signal, an input gate is opened and a clock pulse from a terminal 8 is fed to a counter memory 4 to count while memorized. On the other hand, the output of the FF 2 is converted into a square wave pulse synchronous to an input signal at each negative half-cycle with a phase inverting section 7 and an FF 10. With the output of the output FF 10, an output gate 5 is opened and the clock pulse memorized in the memory 4 is fed to an A/D conversion section 6 to obtain an output voltage corresponding to the input frequency. This enables the extraction of the frequency variation in the input frequency signal as that of the output voltage.

Filed: 1988-04-11
Abstract: PURPOSE:To exactly detect the shift quantity of a light beam by using a track shifting pulse obtained by holding a track cross pulse during a period the light beam passes through an ID area by a latching means. CONSTITUTION:The title device is provided with an ID area detecting means 12, a timing generating means 13 to generate an ID timing pulse, a tracking position error detecting means 7, a track cross pulse generating means 8, a latching means 9 and a counting means 10. Then, the track shifting pulse is generated by holding the track cross pulse during the period the light beam passes through the ID area by the latching means 9, and the shift quantity of the light beam is detected by counting this track shifting pulse. An extra pulse due to the disturbance of a tracking position error signal is outputted to the track cross pulse during the period the light beam passes through the ID area, but since the track cross pulse in this period is held, its excessive influence does not appear in the track shifting pulse. Thus, the shift quantity of the light beam can be correctly detected.
