Title: Subminiature zoom lens
Inventor: TANAKA KAZUO
IPC: G02B15/14
Filed: 1980-03-14
Abstract: PURPOSE: To miniaturize the whole system by providing the 1st lens group of at least ≥2 positive lens and ≥1 negative lens, and the 2nd lens group of at least positive lens and negative lens successively from the object side so that their air interval is variable.  
     CONSTITUTION: From the object side, the 1st positive lens group has at least ≥2 positive lenses and at least ≥1, negative lens, and the 2nd negative lens group has at least one positive lens and at least one negative lens; and air interval D10 between the 1st and 2nd lens group is variable for zooming. Since the 1st lens group and 2nd group are arranged successively, the main plane position at the rear side of the whole system is closer to the object side than the 1st lens group, so the back focus is made much shorter than the focal length of the whole system and the final lens of the 2nd lens group becomes closer to film surface 3, so that whole system is miniaturized. Further, various aberrations are eliminated excellently.

Filed: 1987-02-16
Abstract: PURPOSE:To secure the even chances for transfer of data among devices by controlling the data transfer request signal so that the allocation of the data transfer time is flexibly changed among devices. CONSTITUTION:The control lines 11a and 11b are controlled by an exclusive control circuit 7 so that one of both lines 11a and 11b is validated. A valid period is decided by a valid period timer 9. A valid order applying counter 8 validates both lines 11a and 11b in turn by selecting the valid one of two transfer request signals 4a and 4b for direct memory access controller DMAC. The transfer of data is started when the DMAC transfer request signals 4a and 4b are validated. The DMAC 1a and 1b are selected on the basis of the output of both signals 4a and 4b and then actuated in turn by validating and invalidating these signals 4a and 4b. Thus the time allocation is controlled for transfer of data among devices.

IPC: A62C2/04
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a fire by stopping supply from a fuel feeding device when there is fire near the feeding device. SOLUTION: An fill-up stopping arrangement of the embodiement has a sensor 11 being a flame sensor arranged in a feeding nozzle 5, a solenoid valve 15 to cut off a fuel transportation pipe 7 of a fuel feeding device 1 when a power source is supplied and a control circuit 13 incorporated in a feeding device body 3 to supply the power source to the solenoid valve 15 on the basis of a detecting result obtained from the sensor 11. According to this fill-up stopping arrangement, when a driver brings the feeding nozzle 5 to a fuel filler port of a car with a cigarette in his mouth, the control circuit 13 makes the solenoid valve 15 cut off the fuel transportation pipe 7 by supplying the power source to the solenoid valve 15 on the basis of the detecting result when the sensor 11 detects a flame of the cigarette.  Therefore, the occurrence of a fire of the feeding device can be prevented since filling can not be performed after fuel is forcedly stopped even if the driver tries to fill up the car from the feeding nozzle 5.

Title: Nickel composite conductor for forming electrode and laminated ceramic capacitor
Inventor: SASAKI AKIRA
IPC: H01G4/12
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of ply separation between dielectric layers and internal electrodes and structural defects caused by the oxidation of nickel by integrating specific wt.% nickel with a titanate in a granular state. SOLUTION: A laminated ceramic capacitor using a baked capacitor element as a main parts body is obtained by alternately laminating dielectric layers composed mainly of barium titanate and internal electrodes composed mainly of a composite conductor consisting of nickel and a titanate upon another and pressurizing and baking the laminated body. The internal electrodes are made of internal electrode paste prepared by mixing a composite nickel conductor prepared by integrating 99.5-80 wt.% nickel with 0.5-20 wt.% barium titanate in a granular state in a resin binder. This nickel composite conductor can prevent the occurrence of ply separation between the dielectric layers and internal electrodes and structural defects caused by the oxidation of nickel by reducing the difference in contraction between the layers and electrodes caused by sintering. In addition, the conductor can prevent the occurrence of intermittently disconnecting phenomena in the internal electrodes by nickel. Therefore, the conductor can cope with the thickness reduction of the internal electrodes.

Filed: 1979-03-23
Abstract: PURPOSE: To simplify hoist preparation work on a wire rope and make hoist and divided hanging work simple and safe, by attaching a wire support to the head of a bushing.  
     CONSTITUTION: A wire support 21 comprises an upper ring 22, a lower ring 23, a plurality of struts 24 which couples these rings to each other, etc. The upper ring 22 is provided with a stop plate 25 and a hanging lug 27. A guide member 29 is secured on the lower ring 23. A hold-down plate 31 is secured on the top of the guide member 29 by screws. The support 21 is hung up first. The support is then fitted on the head of a bushing 1. One end of a wire rope 28 is clamped on the hanging lug 27 and the other end is passed through the guide member 29. The latter end of the wire rope 28 is prevented by the hold-down member 17 from dropping off. The support 21 is suspended from a balance 11 coupled to a main hook 9. At that time, an auxiliary rope 7 is fitted on an auxiliary hook 13. The hooks 9, 13 are lifted by winding so that the bushing 1 is hung up to a prescribed height. The hook 13 is then slowly lowered so that the bushing 1 extends vertically and is secured on a mount. Opposite procedures are used to disengage the busing and turn it over to extend horizontally. This results in eliminating high-place work.

Abstract: PURPOSE:To prevent an ion current detecting electrode from staining by connecting a terminal opposite to a terminal, connected to a spark plug, of the secondary output terminals of an ignition coil electrically to the ion current detecting electrode in the predetermined case. CONSTITUTION:When a switch 6 is turned on at normal ignition time, negative high voltage is obtained in the other end of a secondary coil 1b of an ignition coil 1 to generate a discharge between an ignition electrode 3a and an earth electrode 3c by turning off a reverse current preventing diode 7 and turning on a diode 8. When ignition is generated, an ion current is detected in an ion current detecting circuit 4 through an ion current detecting electrode 3b. Next, at the time of cleaning the ion current detecting electrode 3b, a discharge is generated between the electrodes 3a, 3b and the earth electrode 3c by turning off the switch 6, turning on the diode 7 and turning off the diode 8. In this way, the ion current detecting electrode 3b, when it is stained by soot and the other oxide, is cleaned.
