Title: Objective lens system for imaging inclined object surface
Inventor: UETAKE TOSHIFUMI
IPC: G01P13/00
Filed: 1990-10-05
Abstract: PURPOSE:To precisely observe the cross section of a liquid column having a free surface in a very small gravitational environment by tilting the plane of a photoreceptor element along an inclined image surface and, at the same time, correcting the astigmatism as smaller as possible. CONSTITUTION:An objective lens system provided with a front-group lens arranged near a liquid column and rear-group lens arranged on a photoreceptor element and meeting formulae, 1.0<=¦F2/F1¦ (I), -6.0<=F<=-1.0 (II), and -5.0<=ENP/F1<=-0.7 (III) is used for taking the surface of an object inclined against an optical axis in the liquid column having a nearly cylindrical shape. The F1, F2, and F (F=F1/Rc) of the formulae respectively represent the air-side focal distance of a synthetic system of the refracting power of the liquid column in a vertical plane and the front-group lens, the focal distance of the rear-group lens in the vertical plane, and focal distance of a synthetic system of the front-group lens and the refracting power of the liquid column normalized with Rc. The Rc and ENP respectively represent the radius of curvature of a cross section perpendicular to a bus-bar at the central part of the liquid column and the position of the entrance pupil of the front-group lens measured from the point of the object. The formula I expresses the condition about the power distribution between the front- and rear-group lenses of the objective lens and II is a substantial condition under which most of astigmatism can be corrected by only using the front-group lens containing the refracting power the liquid column.

IPC: F16H61/04
Filed: 1991-09-24
Abstract: PURPOSE:To solve both problems of a step-up in gear-off resistance and an increase in shift time by holding the extent of engine speed larger than that of clutch disk rotational speed till a gear-off motion is finished by an up-shift at the time of low oil temperature and, after the gear-off operation is over, lowering the engine speed so as to accord it with the output rotational frequency of a transmission by degrees. CONSTITUTION:Engine speed NE is held to be larger than clutch disk rotational speed NC till a gear-off motion is finished by an up-shift at time of a low temperature of oil in a wet clutch 1. After the gear-off operation is over, the engine speed is controlled by a driving system controller and/or an engine controller so as to be gradually lowered in order to accord with power speed of a transmission through a smaller one than the clutch disk rotational speed NC. With this constitution, the extent of gear-off operating force is reduced and a synchromesh becomes smooth.

Title: Semiconductor device
Inventor: HIRASHIMA TOSHINORI
IPC: H01L23/48
Filed: 1984-12-24
Abstract: PURPOSE:To prevent unexpected accidents such as contact of terminals, by bending external connecting terminals so that the connecting terminals are overlapped, and improving the strength without shortening the distance between the terminals. CONSTITUTION:Leads 4 and 5 are bent in an overlapped state. Tip parts 4a and 5a of the leads are compressed to the base parts of the leads 4 and 5 by a package 6. As a result, the mechanical strengths of the leads 4 and 5 become approximately twice, but the area observed from the upper part is not changed. Therefore, the strengths of the leads can be improved without changing the intervals between the leads 4 and 5 and the neighboring other leads. Thus the integration degree of an IC chip 2 is improved. Even if the number of the leads is increased thereby, accidents such as contact between the leads can be decreased.

Title: Semiconductor device
Inventor: TAKIGAWA AKIRA
IPC: H01L21/761
Filed: 1984-12-24
Abstract: PURPOSE:To prevent a parasitic PNP transistor from being formed, to improve characteristics of a transistor, and to manufacture the IC operating stably, by forming an N<+>-type diffusion layer extended from an N<+>-type buried layer between an N<->-type semiconductor region and an isolation P-type layer. CONSTITUTION:An N<+>-type buried layer 2 is extended to below an isolation groove 4, and an N<+>-type diffusion layer 9 with a high concentration is formed between the periphery of an N<->-type mesa semiconductor region 3a and an N<+>-type buried layer extension. A portion of the N<+>-type diffusion layer 9 serves as a collector taking-out section 8 where a collector electrode C is provided in a groove. In an IC structure having an NPN transistor so constructed, its base would be coupled to the isolation P-type diffusion layer in the peripheral groove when being saturated to result in a parasitic PNP sub-transistor. However, by forming the N<+>-type diffusion layer 9 with a high concentration on the periphery acting as the base of the PNP sub-transistor, amplification factor alphaof the PNP sub-transistor is reduced and thus its operation is prevented. In this way, transistor characteristics can be improved and the transistor can be operated at a low consuming power.
