Title: Magnetic video recording and reproducing device
Inventor: TANIGUCHI YASUHIRO
IPC: G11B33/10
Filed: 1984-06-11
Abstract: PURPOSE:To reduce both power consumption and heating values by controlling an illumination device which illuminates a cassette tape inserted according to a selected action mode and therefore turning off or reducing the lighting power of the illumination device in an action mode that lasts for a long period of time. CONSTITUTION:When a cassette tape is loaded to a magnetic video recording/ reproducing device, the 1st switch SW1 is closed to turn on lamps 2 and 3. If an action mode like a rapid traverse or rewind mode, etc. is selected under such conditions, the 2nd switch SW2 is kept closed with lamps 2 and 3 kept on respectively. When a record mode is selected, the SW2 is opened electronically by the record signal to turn off both lamps. These lamps 2 and 3 are kept on for a short period during which a stable tape drive state is secured after the record mode is selected. Thus a driving tape can be observed. In a reproduction mode, the SW2 is opened electronically with the reproduction signal to turn off both lamps 2 and 3. These lamps are kept on for a short period during which a stable tape drive state is secured after the reproduction mode is selected. Thus it is possible to observe the driving tape.

Title: In place of game parking lot management apparatus
Inventor: TOKUDA KATSUNORI
IPC: G06Q50/10
Filed: 1991-04-23
Abstract: PURPOSE:To enable unmanned management of a parking lot for a game house. CONSTITUTION:A card issuance machine 7 at the entrance issues a prepaid card, an entrance gate 3 is opened to allow a car to come in, and the current time is written to the prepaid card as a gate opening time. When the prepaid card is used to get balls from a ball vending machine 9 in a game house 8, the system thinks that a game is being played and the ball vending machine 9 causes a 'used' code to be written to the prepaid card. When the car is going to leave the parking lot, the system determines whether or not the parking lot has been used for the purpose of playing games by checking whether or not a 'used' code is written to the prepaid card. If it is for playing games, an adjustment machine 6 causes an exit gate 4 to be unconditionally opened while if it is for other reason, the parking charge is calculated based on the relationship between gate opening time and current time stored in the prepaid card and the exit gate 4 is opened after the system detects the calculated amount of money being put into the adjustment machine 6.

Filed: 1986-05-23
Abstract: PURPOSE:To increase the noise margin with respect to a noise signal by inserting a collector and an emitter of a transistor (TR) in a series path regulator to an earth side power line and providing a voltage level adjusting means to an input terminal of the hot line side. CONSTITUTION:The collector/emitter of a TR 12 are inserted to a power line 16 of the earth side. Further, an input terminal 192 of the earth line side is connected to a current flowing side 20 of the TR 12. Then a resistor 21 as a voltage level adjusting means is provided between the input terminal 191 of the hot line side and the signal input section 173 of an electronic circuit 17. Thus, a voltage difference by the collectoremitter voltage of the TR 12 is generated between the earth line side input terminal 192 and the earth side power line 16. The potential of the earth line side input terminal 192 is made lower than that of the earth side power line 16 by the voltage difference. Thus, the noise margin with respect to a noise signal is increased for the share.
