Title: Optical displacement detector
Inventor: YOSHIIKE KATSUSHI
IPC: G01D5/36
Filed: 1986-10-20
Abstract: PURPOSE:To eliminate a deformation error by simple structure and to improve measurement accuracy by fitting one scale member where a scale for displacement detection is formed and the other light-transmissive scale member integrally across the scale for detection. CONSTITUTION:The scale member 20 is made of rectangularly sectioned thin plate type glass and provided with the scale 12 for displacement detection which consists of many slits lengthwise on the surface. The other scale member 30 is made of the same material with the member 20 and has the same shape and the same size and is joined with the member 20 across the scale 12 to constitute a reference scale member 10. Then even if the member 10 curves and deforms in the direction of the thickness (t), the overall length of the scale 12 is unchanged as well as the longitudinal neutral axis Y-Y of the whole member 10. Therefore, an INDEX scale member 40 is supported slidably along the member 10, so a detecting circuit 57 performs detection with specific accuracy without containing an error due to thickness-directional deformation. Further, even if the member 10 curves and deforms in the direction of the width W, no error is generated as well. Thus, a detector which is increased in the clearance (c) between the scale 12 and the scale 42 of the member 40 is realized.

IPC: H01L21/8222
Filed: 1986-10-20
Abstract: PURPOSE:To prevent the deterioration of breakdown strength by performing an ion-implantation into polysilicon having a thin film at an interface between silicon and polysilicon, thereby forming an emitter of a high-gain transistor. CONSTITUTION:An oxide film 5 is formed at the surface of an N-type impurity layer 3 that is formed at the surface of a P-type semiconductor to make a nitride silicon film 8 grow on the oxide film 5. And the above films 8 and 5 are etched by using a resist and a thin oxide film 9 is formed by removing the above resist. After growing polysilicon 10 on the film 8, 9, it is left only at a desired emitter part and others of polysilicon at other parts are removed. Then ion-implantation of an N-type impurity is carried out into an emitter- collector contact formation part as well as polysilicon 10 by using the resist as the mask. As a result, even if a high speed transistor renders its emitter more shallow, a high-speed and high-gain transistor can be simultaneously formed without deteriorating the breakdown strength.

Abstract: PURPOSE:To prevent the occurrence of cracks in a ceramic chip part or solder by forming a soldering lead by bending part of an electrode outwardly thereby giving spring characteristics to the electrode and absorbing mechanical stresses applied to jointed solder by the electrode having the spring characteristics. CONSTITUTION:In a ceramic chip part comprising a construction having a ceramic 1 and metal electrodes 6 covering both the ends of the ceramic 1, part of the electrode 6 is bent outwardly thereby forming a soldering lead 2. Then, if the temperature of an aluminum substrate 5 rises, the aluminum substrate 5 is deformed more than the ceramic chip part because the coefficient of linear expansion of the aluminum substrate 5 is higher than that of the ceramic chip part, so that mechanical stresses are applied to a solder part 3 which joints the ceramic chip part to the aluminum substrate 5 but the mechanical stresses can be absorbed by the deformation of the soldering lead 2, thereby preventing the occurrence of cracks in solder connecting the ceramic chip part to the aluminum substrate.
