Title: Remote control relay
Inventor: FUJIHISA HIROAKI
IPC: H01H50/34
Filed: 1990-05-23
Abstract: PURPOSE:To obtain a relay having a small operation current and an operating electromagnet device with good balance by providing a repelling spring on a link which carries out the making and breaking of a movable contact in association with a plunger of the operating electromagnet device. CONSTITUTION:A repelling spring 30 supported by a supporting pin 13 of a link 12 serves to press the link 12 so as to pinch it. With this construction, in the 'on' state, the spring 30 does not give the link 12 a revolving force, while in the off state, one end 30c abuts on the internal surface of a base, and thereby the spring 30 is pushed downward. One end 30a energizes the link 12 to turn in the direction of arrow B. This force makes a plunger 5 move in the direction of arrow A and becomes a repelling force which reduces the attraction of the plunger 5. Accordingly, an electromagnet device having a good balance in its attraction at the time of ON and OFF operation is obtained and also a relay having a small operation current is obtained.

Title: Color photosensitive silver halide material
Inventor: NAKAMURA SHINICHI
IPC: G03C1/06
Filed: 1981-08-24
Abstract: PURPOSE:To improve the gradation of the highlighted part by adding specified phthalic esters to an emulsion layer contg. silver halide particles having a specified particle size distribution. CONSTITUTION:Phthalic esters represented by general formulaI(where each of R1 and R2 is 6-12 C alkyl, and they are identical with or different from each other) are added to an emulsion layer contg. silver halide particles having <=0.9mum average particle size or to a layer adjacent to the emulsion layer. In the emulsion layer >=95% of all the particles are distributed within + or -40% of the average particle size. The preferred average particle size is 0.2-0.9mum, and >0.9mum average particle size is not effective. When the C numbers of R1 and R2 are <=5, an effect of providing a soft tone to the highlighted part is not produced, and when the C numbers are >=13, the dispersion stability is reduced.

Title: Automatic changer for lubricating oil of submerged rootsigma blower
Inventor: OONISHI YOSHIHIRO
IPC: F04C18/18
Filed: 1977-11-05
Abstract: PURPOSE: To always automatically change oil without lifiting up a blower and pipes, by lubricating the blower by the projection of the clean oil filtered during operation and sequentially returning the oil from a gear chamber to an oil tank.  
     CONSTITUTION: When the blower is in operation, a part of the discharged air flows into a first and a second branch pipes 12, 13. The oil filtered by a filter net 22 in the oil tank 21 and staying in a chamber (a) is sucked up through a suction pipe 15 and an ejector 16 and is projected to gears 5 through a first pipe 17 while the oil is mixed with the air. Thereby, the gears 5 and bearings in the gear chamber 6 are lubrciated. Simultaneously, the oil in the gear chamber 6 is sucked up toward a chamber (b) of the oil tank 21 through a second pipe 18 by the ejecting action of a second ejector 20. Thus, the oil circulates through the oil tank 21 and the gear chamber 6.

Title: Method and device for read and/or erasure of information on magneto-optical recorder
Inventor: MATSUI TAKESHI
IPC: G11B5/02
Filed: 1987-05-30
Abstract: PURPOSE:To make a main and a sub scanning mechanisms unnecessary, to miniaturize a device, and to lower a price, by using a plate shaped magnetic material in addition to an on-going electromagnet. CONSTITUTION:The write of a information is performed by projecting a light spot on the surface of a card 3 via a polygonal mirror 5 and a lens array 4. At this time, since the direction of the magnetic field of a plate shaped magnetic medium 2 arranged in parallel with the projecting direction Y of the polygonal mirror 5 is set in a constant direction, the information is written on the part of a recording bit 31 on which the light spot is projected. When it is desired to erase a record at an adjacent recording bit 31' simultaneously, it is enough to set the plane shaped magnetic material 2 so that the direction of the magnetic field of the plane shaped magnetic material 2 can be set in a direction opposite to that at the time of recording. Thus, by using the plate shaped magnetic material 2 as a magnetic material to apply the magnetic field, it is possible to reduce the number of scanning mechanisms and to realize the miniaturization and the low price of the device.

Title: Radio equipment
Inventor: OHASHI TOSHIO
IPC: H04B1/40
Filed: 1987-05-30
Abstract: PURPOSE:To improve the safety of a system by providing a channel monitoring section, a timer, a transmission output detection circuit and a power switch to a radio equipment so as to prevent the disturbance to a control radio channel. CONSTITUTION:A channel monitoring section 5 stores in advance a control radio channel (C-CH) and sends a clock permission signal to a timer 6 when a channel setting signal set from a logic setting section 2 to a radio section 3 is coincident with the C-CH. On the other hand, a transmission output detection circuit 7 extracts a signal from the antenna terminal of the radio section 3 and detects it, and sends a clock permission signal to the timer 6 during the transmission. The timer 6 applies count when the permission signal is given from both the monitor section 5 and the circuit 7, and a power interruption signal is sent to a power switch 8 when the count exceeds a maximum time. The switch 8 interrupts all the power supplies of the radio equipment or the power supply of the transmission section to stop the transmission. Thus, the consecutive transmission to the C-CH is prevented at the malfunction of the radio equipment.
