Title: Glass element for optical use
Inventor: FUKUTE KAORI
IPC: B82Y30/00
Filed: 1990-01-23
Abstract: PURPOSE:To shut off the contact between optical glass and the atm. and to prevent the generation of weathering as well as to stabilize the characteristics of the optical glass over a long period of time by coating the entire surface of the optical glass with a film of 30 to 350 nm thickness consisting of fine particles of MgF2 having <=30 nm diameter. CONSTITUTION:The entire surface of the optical glass is coated with the fine of 30 to 350 nm thickness consisting of the fine particles of the MgF2 having <=30 nm diameter. For example, the opposite angles of the optical glass 1 which constitutes a rectangular parallelopiped filter are pinched by suitable jigs 2 and the entire part of the optical glass 1 is dipped into a dipping liquid 4 packed in a suitable container 3 to stick the dipping liquid thereto. Even the glass which is inferior in chemical durability is thereby coated with the film of the fine particles of the MgF2 having the excellent chemical durability over the entire surface thereof. Since the contact of the glass and the atm... is shut off, the generation of the weathering is suppressed over a long period of time. Since the optical glass 1 is coated with the MgF2 having a low refractive index as a protective film 5, there is an antireflection effect and the transmittance of the glass element is stably maintained over a long period of time.

Title: Control device for angle of advance for ignition of engine
Inventor: INOUE TAKUMI
IPC: F02D35/00
Filed: 1982-01-28
Abstract: PURPOSE:To eliminate fluctuation in angle of advance and prevent the wear of a spindle, a weight pin and an elongated guide hole to improve the durable accuracy by an arrangement wherein a centrifugal advance mechanism is allowed to fulfil the same function as the centrifugal angle of advance by the negative pressure control of a negative pressure advance angle mechanism. CONSTITUTION:The arrangement is made such that a solenoid valve 31 is opened for a predetermined time after it receives an ignition signal transmitted by a control unit 38 so that a characteristic proportional to the number of revolutions of the engine can be obtained. The negative pressure in a negative pressure sensing port 3 is controlled by the solenoid valve 31 and orifices 35, 36 in proportion to the number of revolutions of the engine and is introduced through hoses 32 and 33 into a negative chamber 11 of a diaphragm 8. Therefore, a turning base plate 6 is turned reversely to the direction of rotation of a revolving shaft 4 by the force which is transmitted through a link 9 and the magnitude of which is determined by the balance between the force produced by a differential pressure between an atmospheric pressure chamber 10 and the negative pressure chamber 11 and the compressive force of a spring 12 thereby turning an ignition advance angle setting element 7. As a result, the characteristic of angle of advance  of the engine can be obtained which includes both functions for angle of advance by negative pressure and by rotation.

At this moment, the detection results of a voltage detector 25 is supplied to the circuit 31, and an indication displayed on a liquid crystal panel is caused to flash, whereby the user is informed that a printing operation is not possible. In addition, in a case where the circuit 31 and the printing circuit 32 are both in operation, when the voltage of the battery is equal to or less than V1 and V2, the transistors 26, 29 are both switched off, whereby the operations of the circuit 31 and the printing circuit 30 are made impossible.

Filed: 1988-01-27
Abstract: PURPOSE:To improve service for subscriber by accumulating voice/data during a time when a subscriber is absent or a telephone set is being used for other purpose and automatically taking out the accumulated information at a time when the subscriber accesses an electronic exchange. CONSTITUTION:Based on a voice accumulation service request from a subscriber, a service grade is preliminarily registered in a line exchange system 1. Upon the end of the voice/data accumulation, completion information from respective voice/data accumulation systems 11, 12 are received by a subscriber response system 13; when the line is currently busy, accumulation informing tone is transmitted to the subscriber-side for a determined time to inform the subscriber. When the subscriber recognizes the accumulation information tone and dials a special read dial, the system 1 transmits, to the subscriber, the voice/data from the respective accumulation systems 11, 12 via the subscriber response system 13 from the point of time when said dialing is performed. As a result, such an inconvenience that a subscriber can not confirm accumulated voice or data through automatic operation can be eliminated, hence the service is improved.
