Title: Steering damper
Inventor: TAKAHASHI HIROTOSHI
IPC: F16F9/12
Filed: 1985-07-10
Abstract: PURPOSE:To decrease a damping force in low and high-speed areas and increase it in a medium-speed area, cope with disturbances in the low-speed area, and decrease the damper torque at a large steering angle in the high-speed area by providing a control means changing the opening of oil paths between oil chambers in response to a car speed. CONSTITUTION:A rotor 9 and a valve 11 are inserted in a housing 7, the valve 11 is rotated in response to a car speed, and a handle is rotated to rotate the rotor 9. First in a low-speed area, the handle is located not to block oil paths, and chambers S1 and S2 are communicated and chambers S3 and S4 are communicated. Furthermore, when a handle is rotated to rotate the rotor 9, gaps d1, d2 are expanded, and the damper torque at a large steering angle can be decreased. Next,when a car speed is increased, the valve 11 is rotated by a step motor, oil paths 10a, 10c are blocked, and S1, S2 and S3, S4 are cut off except for the gaps D1, d2 to increase a damping force, thus allowing to effectively cope with disturbances. When the car speed is further increased, the handle again opens the oil paths to decrease the damping force.

Title: Semiconductor device having field shield structure and its manufacture
Inventor: GOTO HIROSHI
IPC: H01L21/76
Filed: 1988-06-20
Abstract: PURPOSE:To prevent generation of short-circuit of an electrode and enable improvement of pressure resistance and reduction of capacity by inclining the side face of a conductive layer which constitutes a field shield, and controlling the thickness of an insulation layer provided on the conductive layer independently. CONSTITUTION:The sidewall of a conductive layer 12 in an opening 13 is made into a slant 15 that inclines gradually to the outside of an element formation area 14 toward the upside of an opening 13. A gate electrode 17 has a part that extends above the slant 15 of the conductive layer 12. This extension part is insulated from the conductive layer 12 by an insulation layer 16 which is formed by oxidizing the surface of the conductive layer 12. On the conductive layer 12 and the gate electrode 17 is formed an interlayer insulation layer 20. That is, even if the gate electrode 17 is patterned by anisotropic etching, a conductive substance does not remain at the slant 15, and these is no fear of the gate electrode 17 and the silicon substrate 10 being short-circuited. Also, since the insulation layer 16 and the gate insulation layer 18 are formed in separate processes, the insulation layer 16 can have enough thickness, and the desired pressure resistance is given to between the conductive layer 12 and the gate electrode 17, and also the capacity between these is reduced.

Title: Infrared optical parts
Inventor: TOMITA YOSHIHIRO
IPC: G01J1/04
Filed: 1990-06-11
Abstract: PURPOSE:To allow easy working to arbitrary shapes and to eliminate the need for an antireflection film by constituting the above parts of a material formed by uniformly dispersing a specific powder which allows the transmission of IR rays into a medium consisting of a material which allows the transmission of the IR rays. CONSTITUTION:A Fresnel lens is constituted by using the material formed by uniformly dispersing the powder 2 consisting of, for example, germanium, into the medium 1. The material having the refractive index different from the refractive index of the material of the medium 1 is used as the material of the powder 2. The grain size of the powder 2 is reduced to the size sufficiently smaller than the wavelength of the prescribed IR rays and to the size approximate to the wavelength of visible rays by a grinding method. After this powder is dispersed into the medium 1 having thermoplasticity, the dispersion is press formed by molds. Then, the grain size of the powder 2 is approximate to the wavelength of the visible rays and, therefore, the visible rays are reflected and refracted by the boundary between the particles 2 and the medium 1 and are finally irregularly reflected. The rectilinear advance of the rays is thus substantially prevented. The antireflection effect is obtd. in this way by properly selecting the refractive index of the medium 1. Easy working to arbitrary shapes is thus executed.

Title: Ttl focusing detector
Inventor: EGAWA TAKESHI
IPC: G02B7/36
Filed: 1983-08-20
Abstract: PURPOSE:To detect the real extent of shifting by detecting the light for a subject to be photographed passed through a photographic lens, detecting the extent of shifting of an image formed through the photographic lens from an expected focal plane, and excluding the influence of on-axis chromatic aberration from the detected extent of shifting. CONSTITUTION:Focus detecting operation is repeated through a focusing optical system to discriminate a focusing state. When the lens is not in focus, a digital code signal regarding the on-axis chromatic aberration is read again out of the ROM in an output circuit 51 on the basis of the relation between a brush BR1 and a code plate CD1 according to newly adjusted photographic distance corresponding to the position of a focusing ring FR, so that the address specification of the ROM varies with the code signal. The chromatic aberration to the newly adjusted photographic distance (magnification) is updated, so distance measuring operation is repeated in this state to use optimum on-axis chromatic aberration as the base of the arithmetic of a defocusing extent, attaining more accurate focusing detection.

Filed: 1977-12-17
Abstract: PURPOSE: To provide a pause detector, which is so stable as is not influenced by the fluctuations in the main voltage, by connecting two sets of charge and discharge circuit in opposite directions between the base and emitter of a switching transistor.  
     CONSTITUTION: In response to the reproduction of records in a tape 1 running at a high speed, the capacitors C 1  and C 2  of charge and discharge circuits, which are connected in opposite directions between the base and emitter of a switching transistor Q 1 ' and which have larger and smaller time constants, are charged at the same rate through a limitter amplifier 4. As a result, even if the main voltage is varied to fluctuate the output of the amplifier 4, the transistor Q 1 , receives no influence therefrom. Thus, upon detection of the band of no signal of a pause between  musics, the transistor Q 1 ' is rendered conductive a preset time after the start of the  detection of the no signal band in accordance with the difference in the discharge  constances between the capacitors C 1  and C 2  so that the tape 1 restores its play  speed by the action of the plunger which is energized through transistors Q 2 ' and  Q 3 '. Thus, it is possible to stably detect the pause without any influence from the  fluctuation in the main voltage.

Filed: 1993-06-23
Abstract: PURPOSE:To provide a projection exposure device with a pattern position detec tion device which can detect an alignment mark accurately by preventing an asymmetry in a detected waveform caused by the irregularity in the thickness of a resist film. CONSTITUTION:In the title device with a TTLL-system alignment mark detection optical system. an incoherent light source 203 with a wide wavelength is used as the illumination light of the detection optical system, thus preventing the asymmetry of a detection waveform caused by the irregularity in the thickness of resist.

Title: Method for forming electroconductive two-tone tubular film
Inventor: NAKAZAWA TOSHIYUKI
IPC: B29C48/335
Filed: 1982-09-02
Abstract: PURPOSE:To form readily an electroconductive tubular film having transparent part, by selecting the viscosities of two raw resins, making the resin passages of an extruder appropriate, and using an air-cooling ring capable of adjusting partial cooling. CONSTITUTION:A thermoplastic resin (e.g. vinyl chloride resins) containing 30wt% or more carbon and a transparent thermoplastic resin free of carbon are selected such that the viscosity ratio of the former to the latter is 30:1 or less, and the thus selected resins are fed into an extruder. The cross-sectional areas of the passages of the extruder for said resins are constructed such that said area for the carbon-containing resin with a higher viscosity is large and said area for the transparent resin with a lower viscosity is small. The air-cooling ring can adjust partial cooling, and when an adjusting bolt 10 is fastened to lower a screening plate 9, the air amount of the side of the carbon-containing resin where the cooling rate is higher can be lowered to weaken the cooling, so that the intended electroconductive two-tone tubular film stock for producing an electroconductive bag can be readily produced.
