Title: Burglarproof device for automobile
Inventor: GOTANDA MOTOHIRO
IPC: B60R25/04
Filed: 1989-04-06
Abstract: PURPOSE:To make a starting circuit inoperative to prevent burglary even when an automobile is robbed and a door is opened by providing an engine start detector, a door opening detecting switch, a code number input device, a coincidence output holding circuit, a selection circuit, an off control circuit of an engine circuit, and a delay reset circuit. CONSTITUTION:When a door is opened in an engine stopped state, a door opening and closing detecting switch 1 turns on, and a signal of the switch 1 operates a door opening and closing detecting circuit 2 for inputting the signal to a delay reset circuit 12. Accordingly, since the circuit 12 starts to turn off a coincidence output holding circuit 10, for example, after 10-30 seconds, when the engine is started a contact 18 turns off to immediately stop an engine. But, when the engine is restarted within 10-30 seconds even if the door is opened, the engine starts because a coincidence output is outputted from the circuit 10. When the switch 1 detects the opening of the door in the engine stopped state, a code number checking circuit 9 is reset to have the holding output of the circuit 10 cleared. Therefore, the engine is started but it cannot start after 10-30 seconds unless the code number is inputted again.

Title: Magnetron
Inventor: SAITOU HISAO
IPC: H01J23/20
Filed: 1981-06-04
Abstract: PURPOSE:To plan to make the size compact and to improve the load stability by a method wherein, in connection with imprivements in the construction of the anode, panes are so fixed that they are placed at a preset angle to an axis of an anode cylinder. CONSTITUTION:A plurality of panes 6 are fixed radially to the inside wall of an anode cylinder 5 and each of every two panes 6 is linked together with two kinds of large and small strap rings 7, 8. Each pane 6 of a magnetron is fixed to the inside wall of the anode cylinder 5 in such a manner that it is placed at a preset angle theta to an axis B. Consequently, even if the height H of the pane 6 is assumed, for instance, 10x, its hight H in the axial direction can be 8x, so that the configuration of a magnetic circuit may be made compact. In addition, because an electronic spoke is formed so that it tilts at an angle of theta, the length of the anode becomes h and as a result the load stability becomes equivalent to what has had the pane with the conventional height h.

When reading out the information, an optical beam which has a wavelength being almost near an energy band gap of the thin film 7 and causes no damage is irradiated to the disk 1 from the light source means 9. The irradiating optical beam reaches the thin film 7 through the transparent electrode 8, and an optical electromotive force corresponding to the recorded information is generated, and led to a detecting part 10 through the transparent electrode 8 and a rear side electrode 6. In this way, a reproducing optical system is simplified, and also an inexpensive material can be used for the recording thin film.
