Title: Semiconductor device
Inventor: TSUTSUMI HIROYUKI
IPC: H01L21/60
Filed: 1992-03-02
Abstract: PURPOSE:To realize a reliable junction with a flat surface of a bump, by forming an interlayer film smaller than an interlayer opening and located at each opening part of interconnecting patterns in a semiconductor device. CONSTITUTION:A contact region, through which first-layer Al wiring pad 2a, a second-layer Al wiring pad 2b, and a third-layer Al wiring pad 2c are electrically connected, is formed around a bonding pad while first and second interlayer films 3a and 3b are formed at a central part of the bonding pad. Since these two interlayer films 3a and 3b raise the height of a central surface of a bump 4 by their thicknesses, unevenness in the surface of the bump 4 is reduced. Consequently, the bump 4 is adequately put in contact with an inner lead 7a, and thereby thermal energy of a laser beam is effectively transmitted from the inner lead part 7a to the bump 4.

Title: Electromagnetic driving device and optical disc device utilizing same
Inventor: YAMAZAKI HIDEO
IPC: H02K33/18
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a stabilized driving force and control the positioning of an objective lens surely by a method wherein two sheets of plate-type permanent magnets, having the same configuration, are pinched by two sheets of plate-type yokes, having the same configuration, from the direction of magnetization while aligning the direction of the magnetization thereof. CONSTITUTION:Permanent magnets 4, 5 are pinched by yokes 2, 3. There are two routes of flux and one is a route R1 passing through a magnetic gap while the other is another route R2 passing through ambient air. When magnetic saturation is generated in the yoke 3, flux will never flow through a section inside of imaginary sections, shown by slant lines, while the flux passes through the route R2x, the route R2y or the like to avoid to pass through a section inside of the imaginary sections. The flux, passing through the magnetic gap, is not changed even under the condition of magnetic saturation whereby the distribution of flux density is kept in constant even when a magnetic circuit 1 is miniaturized. A stabilized driving force is obtained from an electromagnetic driving device 10 in which a coil 6 is inserted in the magnetic gap.

Abstract: PURPOSE:To prevent displacement of the end face of the strand of an optical fiber for a long period, by inserting the optical fiber into the hole of a ferrule after removing the sheath and forming a spherical expanded section at the front end of the strand, and then, installing a holder which supports the spherical section to the ferrule. CONSTITUTION:After removing the jacket 4 and outer sheath 5 of an optical fiber 1 in steps, the optical fiber 1 is inserted into the hole 11 of a ferrule 10. Then the front end of the strand 2 of the optical fiber 1 is heat-molded and a spherical expanded section 6, whose rear surface is engaged with the ferrule 10, is formed, and then, the front side outer peripheral section is held by a holder 13 against the ferrule 10. The holder 13 holds the spherical section 6 with the inner surface of its tapered hole 13a and is screwed in the front end part of the ferrule 10. Therefore, displacement of the strand during the period of using can be prevented and the optical coupling efficiency of this connector can be improved because of the lens effect of the spherical section.

IPC: H04M3/26
Filed: 1981-03-26
Abstract: PURPOSE:To always monitor a bus circuit of a device to be controlled and a control bus for normality, by transmitting the order for confirmation of control bus normality from a controller to the device to be controlled, independently of an operation timing of program control. CONSTITUTION:An order transmission circuit SD of a controller generates an instruction of bus test on a control bus independently of a CPU. The transmitted data are received to a bus receiver of the controller via a bus circuit in a device to be controlled, a bus receiver CR, a register REG, an order decoder DEC, a selector SEL, a bus driver DC and a control bus. At the operation, a coincidence circuit M is operated, transmission data is compared with reception data, and if they are dissident, the number of devices to be controlled which is regarded as failure is registered in a cue memory Q-MEM. In the CPU, the number of a failed devices to be controlled is discriminated or discrimination is performed as to whether if the bus itself is in failure or not by reading the Q-MEM in the speed not effected with the processing ability.

SOLUTION: This fertilizer is produced by the following process: 50 wt.% of fowl dropping as feedstock adjusted to 60 wt.% in water content is incorporated with 35 wt.% of peat with the water content of 26 wt.% to product a mixture about 35 wt.% in water content, which, in turn, is further incorporated with about 13 wt.% of pulverized coal <=1 mm in particle size and about 2 wt.% of coral calcium powder. Furthermore, the resulting mixture is incorporated with 2 wt.%, based on the total amount, of a strongly acidic germicidal solution with pH 2.8 followed by agitation for about 20 min. Subsequently, the resulting disinfected mixture is frozed, and then-dried for 10-14 days. Finally, the resultant mixture is crushed with a roller to obtain the aimed lumpy fertilizer with a size of 3-5 mm.

Abstract: PURPOSE: To prevent inadvertent release of parking brake by constituting the engaging pin projected on the plunger of a parking brake so as to be linked with the linkage groove of the linkage band slidably inserted in a plunger guide and permitting double operation of control release.  
     CONSTITUTION: In braking with parking brake, a plunger 9 is pulled by a handle 11, and after braking, the handle 11 is released, then the engaging tooth part 12 of the plunger 9 is linked with the edge 14b of a ratchet 14, and the advance of the plunger 9 is obstructed. As the linkage pin 13 is restricted in the lateral grove 18a of the linkage groove 18 which is formed on the side part of the linkage band 16, the linkage pin 13 is linked with the longitudinal groove 18c even if inadvertent force is applied to the handle 11, and the release of brake is obstructed. In order to release parking brake, the handle 11 is turned clockwise and pulled and further turned clockwise, then the linkage pin 13 is allowed to reach the outer end part B of the lateral groove 18b.

Abstract: PURPOSE:To obtain an economical toner superior in fluidity and triboelectrification characteristics by mixing thermoplastic resin core particles having an average particle diameter of 1-15mum, with a colorant alone, or together with other necessary fine additives, and applying mechanical stress in such conditions as forming an average particle diameter of 1-20mum. CONSTITUTION:The thermoplastic resin core particles having an average particle diameter of 1-15mum are mixed with the colorant alone, or together with other necessary fine additives, and subjected to mechanical stress in such conditions as forming an average particle diameter of 1-20mum, while care is taken lest the resin core particles be melted and attached to each other to form coase agglomerates, or be too finely pulverized by too strong stress, but it is necessary that the colorant powder is attached to the surface of each resin particle and buried into the surface in a state of primary fine particles. It is preferred to control the toner particle size to the range of average particle diameter of 1-20mum and to substantially eliminate the toner particles of <=0.5mum and >=25mum diameters.

IPC: G21C17/10
Filed: 1983-03-17
Abstract: PURPOSE:To enable decision of adequateness of reactor charge by leaving a hafnium and hafnium alloy sample for a specific time or longer in steam kept in a specific temp. and pressure range then observing the sample surface. CONSTITUTION:A sample, hoisted by means of a wire rope formed of a stainless steel or Ni contg. alloy, is supported in an autoclave 11. The temp. is increased in the initial period of temp. elevation which the inside of the autoclave is evacuated with a vacuum pump 25. Valves 12, 13 are opened to supply gradually steam from an autoclave 10 into the autoclave 11 at the point of the time when the temp. in the autoclave 11 exceeds 200 deg.C. The autoclave 11 is further heated up after releasing several times the steam and is maintained at, for example, 475-525 deg.C temp. and 90-120kg/cm<2> pressure, at which the sample is left for 5-25hr and thereafter the sample is observed and the sensitivity thereof to nodular corrosion is decided. The sensitivity of the hafnium and its alloy to nodular corrosion is thus investigated in a short time and the adequateness of the nuclear reactor charge as a hafnium neutron absorber is easily decided.
