Title: Mos type transistor
Inventor: KABASAWA MASAYA
IPC: H01L29/78
Filed: 1990-10-05
Abstract: PURPOSE:To enable MOS type transistors different in gate length and gate width to be integrated so as to improve the circuit integration per area by digging a trench with a specified depth and a circumference in a silicon substrate, and forming a gate electrode through a gate oxide film, at the part corresponding to the valuable wall of the trench. CONSTITUTION:By photolithography technology, a patterned resist pattern 21 is formed, and using dry etching method, with the resist pattern 21 as a mask, a trench with a required depth dimension and a required circumference dimension is dug. Subsequently, an oxide film to become a gate oxide film 14, is so formed that it covers the whole surface of the silicon substrate 11 inclusive of the inside of the trench 3, and a polysilicon film to become a gate electrode 15 is formed in order. Hereby, the depth dimension of the trench 13 dug in the main face of the silicon substrate 11 becomes the gate length L of a transistor, and the sum of each dimension of the circumference of the trench 13 becomes the gate width W, thus a MOS type transistor with various kinds of different gate lengths and gate widths can be integrated within the same area range on the silicon substrate.

IPC: G02B13/00
Filed: 1986-11-11
Abstract: PURPOSE:To remove the influence of moisture absorption upon lens performance by prolonging the curved surface of the effective diameter part of a condenser lens outward as it is or at a constant angle to a tangent to the curved surface, or to a range between two surfaces, and specifying the radial length of the prolonged part. CONSTITUTION:A condenser lens has a fitting part on one surface about the optical axis as the center and includes an aspherical surface formed by plastic molding, the effective radius on a lens surface 12 passing a point 12b on the optical path is a(12), and the curved surface of the prolonged part of a lens surface from its outermost part 12a is 16. Further, when a curved surface formed at a 30 deg. angle to the tangent 17 to the lens surface at the outermost part 12a is 18, the influence of variation in humidity is reduced in a hatched range surrounded with the curved surfaces 16 and 18 in a range of 0.3Xa(12) radially outside the outermost part 12a with the effective radius. Consequently, the influence of humidity is reducible and this objective lens has high accuracy and is hardly affected by environmental variation.

Title: Absolute position display for rotary encoder
Inventor: TAKAMATSU SHIGEHARU
IPC: G01D5/36
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To solve such problems in the prior art that it was difficult to indicate the absolute position by marking indexes on an endlessly rotating rotary encoder, and that the upper limit value was unclear or not precisely indicated even if the absolute position was indicated on a liquid crystal panel or indicators attached to the outside of the control.

Title: Optical encoder
Inventor: RACHI MASAHIRO
IPC: H03M1/22
Filed: 1985-11-29
Abstract: PURPOSE:To improve the dimensional accuracy of parts and to reduce the cost reduction by obtaining the light for feedback of light quantity from the total reflected light transmitted through a transparent acrylic material. CONSTITUTION:The light delivered from a light emitting element 1 is made incident on a rotary disk 3 made of a transparent material like acrylic substance, etc. and reflected by a total reflecting surface 3b to reach a light receiving element 7 for feedback. Here, an incident angle theta1 is defined for the light given onto the surface 3b from the element 1, and the surface 3b is set so as to obtain an incident angle securency the total reflection. Thus no need is required to apply a mirror surface finishing to a part of the disk 3 unlike a conventional case by setting the surface 3b so that an incident angle securing the total reflection is obtained. In addition, both the quantity and the intensity of the light of the element can be detected. If an acrylic material, for example, is used to the surface 3b, the incident angle theta1 is set so as to satisfy theta0<theta1 because the critical angle theta0 that produces the total reflection is equal to about 42 deg.. Thus the totally reflected light is obtained.

Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of quality such as discoloration without carrying out additional heating and thermal insulation of phenol and enable inexpensive transportation and storage as a liquid phase by adding a specific amount of acetone to phenol. SOLUTION: (B) Acetone in an amount of <=70wt.% is added to (A) phenol. The A/B system has no space in the mixture and the coagulating point is about 20 deg.C when the content of the component B is 15% and about 0 deg.C when the content of the component B is 50% and about -40 deg.C when the content thereof is 70%, and environmental temperature for transportation and storage of the component A is normally -20 to +35 deg.C. Therefore, <=70% content of the component B is enough in order to always retain A/B mixture as liquid. Storage in a tank, transportation, etc., by tank lorry is made ready, and further, long- distant pipeline transportation is made economically advantageously possible without requiring thermally insulated pipe. The component B is, as necessary, simply removed by distillation.
