Title: File retrieval system in magnetic tape volume
Inventor: TANAKA ISAO
IPC: G06F12/00
Filed: 1989-03-17
Abstract: PURPOSE:To position a head at high speed by providing a file control information block in front of the BOT (tape top position) of magnetic tape volume, writing a file name and position information on it, and positioning the head by referencing them at the time of accessing. CONSTITUTION:A file control information block 1 is the block which stores the file name and position information (a physical block 1D and a logical block 1D) existing in the magnetic tape volume in front of the BOT. Since the position information executes rough high-speed searching, it consists of the physical block 1D having a value, which is counted up whenever the magnetic tape progresses by a prescribed distance, and the logical block 1D to be serial numbers applied to a data block and a data mark block with the BOT as a reference point. Thus by using the physical block 1D and the logical block 1D and using the high-speed searching function, the head can be positioned at the top of the corresponding file at high speed.

Title: Color cathode-ray tube
Inventor: SUGAWARA SHIGERU
IPC: H01J29/48
Filed: 1990-03-20
Abstract: PURPOSE:To prevent degrading the spot diameter at prescribed positions of a fluorescent plane and improve the resolution of images by dividing electron lens of in-line-type electron guns into two and providing a function to compensate excess or less focusing degree of the first lens to the second lens. CONSTITUTION:A second electron lens L20 having low lens function in Y- direction and long and moderate lens function in X-direction is formed between a third grid 5 and a fourth grid 6. When the voltage of the grid 6 becomes higher than a planed value Vf of a convergence voltage, the lens L20 works as lens having focusing function to the horizontal (X-axis) direction and electron beams 9B, 9R in both sides deflected toward the central electron beam 9G since voltage of the grid 5 is set to be voltage Vf. Since the focusing degree of the first lens L10 is lower than the set value, as a whole the focusing degree becomes the same as the planed value. In the reverse case, the lens L20 works as lens having scattering function and the planed value is compensated.

Title: Pachinko ball discharge device
Inventor: SUZUKI ISAO
IPC: A63F7/02
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To deliver a correct number of pachinko balls from a sprocket and prevent the sprocket from chipping. SOLUTION: When a sprocket 11 rotates, a tooth portion 11b delivers a pachinko ball 2 in a ball receiving recess 11a from the ball receiving recess 11a. In this case, as the tooth portion 11b is provided with a gullet portion 11c, the portion prevents stress from concentrating at the tip of the tooth portion 11b, and prevents the tooth section 11b from chipping. As the tooth portion 11b holds two balls in a non-contact state, the distance between the two balls is decreased. In addition, as the clearance between the circumferential wall of a ball supply route 9b and the gullet portion 11c is smaller than the diameter of the pachinko ball 2, the pachinko ball 2 is prevented from falling from the clearance between the two balls, and generally speaking, when the sprocket rotates, a correct number of pachinko balls 2 are delivered from the sprocket 11.

Abstract: PURPOSE:To realize a vehicle sensor reduced in restriction of installing places and able to be easily installed by transforming the polarizing direction of projected light, reflecting the light and receiving only the light of a prescribed polarization direction out of the reflected light. CONSTITUTION:Light with a fixed polarization direction is projected from a projecting means 101 and a reflecting means 102 transforms the light into a light having a polarization direction parallel to the road surface and reflects the light. A polarizing means 103 passes only the light with the horizontal polarization direction out of the reflected light and other light. Thereby, the reflected light from the means 102 is made incident but light reflected by a vehicle has a polarization direction vertical to the road face and is not made incident. A receiving means 104 receives light from the means 103 and changes an output in accordance with received light quantity. When there is no passing vehicle, much light quantity is received, and when a vehicle passes, the received light quantity is reduced. A sequence means 105 judges the passage of a vehicle based upon an output from the means 104 and counts the number of passed vehicles.

Filed: 1993-03-05
Abstract: PURPOSE:To prevent the unjust use regardless of the use of a contactless card by requiring a prescribed time before a user passes a gate again with the same card after passing the gate once. CONSTITUTION:The user having a card 1 passes near a detector 2 and, is detected by a decoder 3; and when one of plural timers 5 is operated by this passage, the timer 5 is operated for a prescribed time, for example, until the user gets-off from the lift. Therefore, the detector 2 detects the card 1 again if the user transfers his card 1 to his playmate by an unjust method and this playmate will pass a gate 7. Since connection between the decoder 3 and the timer 5 is kept while the timer 5 is operated, the other timers 5 cannot be driven, and he cannot pass the gate 7. When another regular user will pass the gate, another decoder 3 detects his card, and a selector 4 drives another waiting timer 5, and a monostable multivibrator 6 is operated again, and he can pass the gate 7.

Abstract: PURPOSE:To obtain a rated output voltage in a no load state by connecting a voltage detecting part to the secondary side of a transformer rectified and smoothed and also connecting a current detecting part to the low voltage side between the detecting part and a load on the post stage to control a switching TR connected to the primary side of the transformer. CONSTITUTION:A power supply connected to terminals A, B is turned on by connecting the base of a TRQ3, i.e. a trigger terminal B, to the terminal C and its electric power is supplied to a power supply pin 12 of a pulse width control switching regulator IC through a resistor 15. Consequently, the IC is driven, controlled at a prescribed output and boosted, rectified and smoothed by a transformer TR. Current I flowing into an output load L is detected as voltage drop (a) by resistors 21, 22 and compared with a divided voltage C of a reference power supply (f) in the IC to control the pulse width. An output voltage (v) is dropped by resistance division and a difference between the dropped voltage and the reference power supply (f) is found out as a detected voltage (d) and connected to a short protecting circuit by a diode D1. Thus, the power supply is controlled so that the rated output voltage is obtained in the state of no load.
