Abstract: PURPOSE:To reduce the dimension of a power source and reduce the electric- power consumption by installing spark plugs having auxiliary center electrodes into the combustion chamber of a direct-injection type engine and carrying-out fore electric-discharge when fuel pressure is low and carrying-out main electric- discharge, thus lowering the voltage necessary for main electric-discharge. CONSTITUTION:Spark plugs 15 and 16 having auxiliary center electrodes 15c and 16c together with center electrodes 15a and 16a and grounded electrodes 15b and 16b are installed into the combustion chamber of an internal-combustion engine for directly jetting-out fuel into combustion chambers 13 and 14 from fuel injection valves 11 and 12. Fuel pressure sensors 30 and 31 are installed into fuel passages 28 and 29, and the pressure signal is compared with the first set value in comparators 34 and 35, and the signal is compared with the second set value in comparators 36 and 37. When fuel pressure exceeds the first set value, the output of an OR circuit 25 is outputted, and a fore-electric discharge is generated between the auxiliary center electrode and the grounded electrode. When the fuel pressure reahces that on injection start, the output of an OR circuit 26 is outputted, and main electric discharge is generated between the center electrode and the grounded electrode.

Title: Camera using film provided with magnetic storage part
Inventor: SODEYAMA MASAKAZU
IPC: G03B17/28
Filed: 1995-06-29
Abstract: PURPOSE: To beforehand prevent the magnetic powder or the material powder of film from being stuck to the film sliding part of a magnetic head in a camera using film provided with a magnetic storage part. CONSTITUTION: The film 4 fed from a film cartridge 3 passes between a film guiding member 5 and a film pressing plate 8 and is taken up by a winding spool 7. At the time of taking up the film 4 after photographing, information is recorded in the magnetic storage part of the film 4 by the magnetic head 10 attached to the pressing plate 8. The pressing plate 8 is provided with a freely rotatable roller 20 coming in contact with the sliding surface of the film 4 on which the magnetic head 10 slides. When the film 4 is operated to travel, the roller 20 comes in contact with the sliding surface of the film 4 and rotates so as to clean the sliding surface of the film 4, whereby the magnetic head 10 slides on the sliding surface of the film 4 from which the magnetic powder or the material powder is removed.

Title: Optical head device
Inventor: KIMURA YASUO
IPC: G11B7/135
Filed: 1989-06-26
Abstract: PURPOSE:To obtain a compact, light and inexpensive optical head device by utilizing action obtained by composing respective functions of a grating element information signal detecting optical system and a focus error/track error detecting optical system. CONSTITUTION:Linear polarized light 20 projected from a semiconductor laser 19 is made incident upon a double refraction diffraction type element 1 consisting of lithium niobate crystal having the Z axis in the direction rectangu lar to the light 20, but no influence of the incident light is exerted because the incident light is converted into normal light. Since the reflected light reflected from an optical disk 25 and made incident upon the element 21 is converted into normal light by the lithium niobate crystal, the light is diffracted by receiving the action of the grating pattern. For instance, a focus error signal and a track error signal are detected from the output of the 1st photodetector 27 detecting +1st order diffracted light 26 and a reading signal is obtained from the sum of outputs from the 1st photo detector 27 and the 2nd photodetec tor 29 for detecting -1st diffracted light 28. Consequently, the compact, light and inexpensive optomagnetic head device can be obtained.

Title: Error control system for store-in cache directory
Inventor: TOYOSHIMA ATSUSHI
IPC: G06F12/08
Filed: 1990-06-22
Abstract: PURPOSE:To reduce the system stop by reading out data again from the other directory position and using it for retrieving a directory, when a parity error is detected in the data from one directory position. CONSTITUTION:In the case a value of an error retain register 15 is logic '1', a retrieval of a directory 2a is executed again. In this case, since a value of a directory address switching register 11 is inverted, an output of an exclusive OR circuit 12 is logic '1'. When a parity error is detected again in data read out of the directory 2a, an output of a parity checker 8 becomes logic '1', and since the value of the register 15 is logic '1', an output of an AND circuit 14 becomes logic '1' and logic '1' is set to an error register 9. Also, when an error report is executed, the system stops. However, unless the parity error is detected in the data read out again, the processing of a cache access is executed by setting logic '1' to one of a hit register 5 or a miss register 7.

Filed: 1987-06-30
Abstract: PURPOSE:To eliminate the need for a private controlling channel by using a signal line of a commercial channel as a signal line sending a signal from a control station to a controlled station. CONSTITUTION:An out-band signal outputted from a signal generator of a station A (control station) is sent to a station B (controlled station) via a voice detector 1. In detecting the said out-band signal by a signal detector 3, a switch 10 is thrown to the position of a signal generator 5. Then the output of the generator 5 is given to the station A via the voice detector 6. The signal is detected by the signal detector 4 and it is discriminated that the out-band signal from the station A is sent correctly to the station B to stop the output of the generator 2. The detector 3 of the station B detects the stop of the out-band signal from the station A to stop the output of the generator 5 thereby throwing the switch 11 to the position of a terminator 15. Thus, the input to the detector 6 is terminated to interrupt the communication carrier.

Abstract: PURPOSE:To improve the reliability of the operation of a load device by providing a main switch and a subordinate switch and preventing a power source from being turned off until a permit signal is outputted by the load device even if the main switch is turned off. CONSTITUTION:If the main switch 5 is turned off when a power unit 1 is in operation to supply electric power to the load device 6 continuously, a control circuit 2b sends out an inquiry signal to a control circuit 2b. When the load device 6 sends out the permit signal in response to the inquiry signal, the control circuit 2b turns off an internal switch 2a to cut off electric power supply to the load device 6. When the permit signal is not outputted by the load device 6, on the other hand, the control circuit 2b holds the switch 2a 'on' state and turns off the switch 2a the moment the permit signal is outputted to stop supplying electric power to the load device 6.
