Title: Semiconductor device and manufacture thereof
Inventor: NISHIYAMA AKIRA
IPC: H01L27/10
Filed: 1989-02-13
Abstract: PURPOSE:To enable a dynamic type memory device, which is integrated to a high degree and has high reliability, by using a metallic silicide film or the combination of the metallic silicide film and an impurity diffusion layer as a storage node. CONSTITUTION:A metallic silicide film 14 disposed brought into contact with the inwall of a trench 12 formed to a semiconductor substrate 11 is employed as a storage node (a charge storage region), and a capacitor electrode 17 oppositely faced to the storage node through a capacitor insulating film 16 is buried into a trench, thus constituting a semiconductor device. When a charge storage layer is composed of the metallic silicide film 14, a metallic film is shaped and the rounding effect of the corner sections of the trench is acquired through a heat treatment process in the film 14. The reaction is enabled at a comparatively low temperature of approximately 900 deg.C, and the warpage of the substrate 11, the rediffusion of an impurity, etc., are inhibited. When the metallic silicide film 14 is used as the charge storage layer in place of an impurity diffusion layer, the uniform charge storage layer can be shaped easily around the trench. Accordingly, the semiconductor device, which is integrated to a high degree and has high reliability, is acquired.

Filed: 1994-03-01
Abstract: PURPOSE:To provide a method for producing a sulfuric ester salt actualizing a high production efficiency at a low cost, having excellent uniformity and reaction ratio. CONSTITUTION:In producing a sulfuric ester salt by reacting sulfamic acid with a substance to be sulfated, sulfamic acid and the substance to be sulfated are thrown in a premixer 1 and premixed. The mixture is fed to a wet grinder 2 and ground in a wet state. The maximum particle diameter of sulfamic acid is <=600mum, especially 100-300mum. The ground material is thrown in a reactor 3 and sulfamic acid is reacted with the substance to be sulfated at 70-150 deg.C, especially 100-120 deg.C. The blending ratio of sulfamic acid to the substance to be sulfated is in the range of 1/99-75/25, especially 40/60-65/35. Since the grinding is carried out in a wet state, sulfamic acid particles do not coagulate and are uniformly dispersed even after grinding. Consequently, the reaction is uniformly advanced and a high reaction ratio is obtained in a short time. Dust will not occur and the production can be carried out in a favorable operation condition.

Filed: 1985-02-21
Abstract: PURPOSE:To prevent mechanical flare on an image forming plane by forming an installation surface at the side of the optical axis of a lens guide hole and providing a nonreflecting means on the installation surface CONSTITUTION:When the nonreflecting means 20 is set on the installation surface 19, incident light, for example, from above a lens barrel 1 is not reflected because of the nonreflecting means 20. Consequently, no excessive light reaches the image forming plane 24 formed by adjusting focal lengths of lenses 15 and 16 and no mechanical flare is generated. Then, when the nonreflecting means 20 is installed at a lubricating oil stopping means 21, lubricating oil applied over the outer peripheral surface of a lower lens guide ball 18 does not enter the nonreflecting means 20 because of the lubricating oil stopping means 21. The incident light is reflected because of the nonreflecting means 20 and no lubricating oil which reflects the incident light intensely does not enter the nonreflecting means 20, so that prevention against the mechanical flare is further secured. Then, there is lubricating oil present between contacting places between the lower lens guide ball 18 and insertion grooves 13 and 14, so the smoothness of the movement of lens moving frames 3 and 4 is maintained.

Title: Solid-state image pick-up camera
Inventor: NOGA TAKEHIRO
IPC: H04N5/335
Filed: 1985-02-20
Abstract: PURPOSE:To solve problems, which arise when an object moving at a high speed is photographed, without using a mechanical shutter, a stroboscope device, etc., and to obtain a clear picture all the time by providing a control circuit which controls electrically the time for accumulating, in a solid-state image pick-up element, signal charge generated by incident light. CONSTITUTION:The control circuit 6 generates a pulse shaped CCD base impressing voltage Vsub. By driving a CCD 3 with the aid of this Vsub, the signal charge accumulating time of the CCD 3 is controlled. In a conventional CCD camera, the Vsub is fixed constantly at a certain level V0, and the entire signal charge generated by the incident light is accumulated during the period of 1/60sec. Whereas in the CCD camera materialized by this invention, the Vsub level equals V0 only during the period of tsec (0<=t<=1/60) as shown in Fig. (a), and during the other period (1/60-tsec), the level is raised to V1. Accordingly, the signal charge to be accumulated in the photodiode of the CCD 3 all flows into a base during the period of 1/60-tsec. Thus, the signal charge is accumulated in the photodiode of the CCD 3 only for tsec as shown in Fig. (b).

IPC: B29C45/26
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To collapse the balance of the penetration quantity of a resin by non-uniformly planning the wall thickness between a gate position and a weld part without requiring a large correction of a mold or a precise molding machine and to move the weld part from a thin-walled part low in strength to other part. SOLUTION: The position of a weld part generated by the superposition of the flows of a resin injected from the gate position 1b of a buzzer case 1 being one embodiment of a thin-walled box-shaped plastic part is set to one place widest in area corresponding to the bottom surface 1d of the buzzer case 1 to provide a wall thickness non-uniform part 1e. The flow of the resin is accelerated by increasing the wall thickness of the wall thickness non-uniform part 1e to move the weld position generated in a conventional weak strength portion to a place where the influence of strength is reduced. Mechanical strength is increased by the alteration of the weld part and a crack measure is taken. Product yield is also enhanced and the large correction of a mold or an expensive presise molding machine is dispensed with and an inexpensive and highly reliable product can be supplied.

Title: Air-fuel ratio sensor
Inventor: ISHITANI MASAO
IPC: G01N27/419
Filed: 1992-01-23
Abstract: PURPOSE:To detect an air-fuel ratio correctly even in combustion condition close to a logical air-fuel ratio with a low oxygen partial pressure. CONSTITUTION:A second ion transmitting body 8 is baked to be porous forming pores as outflow passages communicating between a measuring electrode 9 and a reference electrode 10. Oxygen in a diffusion chamber 13 in contact with the measuring electrode 9 is ionized by electrons given by the measuring electrode 9 to be transported in order to the reference electrode 10 through oxygen defects in the second ion transmitting body 8, so the electrons are taken by the reference electrode 10 to be oxygen molecules, and they are returned into the diffusion chamber 13 through the pores in the second oxygen ion transmitting body 8. A higher oxygen partial pressure can thus be kept on the side of the reference electrode 10 than that inside the diffusion chamber 13, and the oxygen partial pressure in the diffusion chamber 13 is almost similar to the oxygen partial pressure of actual exhaust gas G.
