IPC: H01L29/861
Filed: 1987-02-09
Abstract: PURPOSE:To increase breakdown voltage by disposing a high resistance film onto a second conductivity type low-concentration diffusion layer and a high resistance substrate on the out side of the diffusion layer through an insulating film in a high breakdown-voltage planar type semiconductor element in which the second conductivity type low-concentration diffusion layer is formed, surrounding a second conductivity type high-concentration diffusion layer in the first conductivity type high resistance substrate. CONSTITUTION:A p<+> type layer 2 in high impurity concentration is shaped to the surface of a high-resistance n<-> type Si layer 1, and a p<-> type layer 6 in low impurity concentration is formed around the layer 2. The total amount of an impurity per unit area at the time of viewing from the surface of the p<-> type layer 6 is specified to 1-5.5X10<12>/cm<2>. An n<+> type layer 9 is shaped around an element separated at a fixed distance from the p<-> type layer 6, and a semi-insulating polycrystalline silicon film 8 is disposed extending over the n<+> type layer 9 from the p<+> type layer 2 through an insulating film 7. When breakdown voltage of 70% of more is permitted at that time, the length of the p<-> type layer 6 extends over 120mum or less when the total amount of the impurity in the p<-> type layer exceeds 4X10<12>/cm<2>. When the p<-> layer is formed at two stages, however, the length of the layer in concentration exceeding 4X10<12>/cm<2> may extend over 120mum or less.

IPC: G03F9/00
Filed: 1992-01-17
Abstract: PURPOSE:To reduce the number of reflection operations or transmission operations by one operation by a method wherein an alignment mark on a substrate is irradiated with a beam of light via a projection optical system which is composed of a reflection and refraction optical system and a beam of light from the alignment mark is detected in a first direction via a light-path splitting member only by one operation.

The beam of exposure light IL which has been transmitted through the mask 4 is incident on a concave reflecting mirror 9 via a first lens group 6, a half mirror 7 and a correction lens group 8. The beam of exposure light which has been reflected by the concave reflecting mirror 9 is directed again toward the half mirror 7 via the correction lens group 8; the beam of exposure light reflected by the semitransmissive mirror 7 is condensed finally on a wafer 11 by using a second lens group 10. Consequently, the image of a circuit pattern on the mask 4 is transferred onto the wafer 11 by using a projection object lens composed of a reflection and refraction optical system.

Title: Fixing method of drum in magnetic detecting encoder
Inventor: SEKIZAWA SADAO
IPC: F16D1/06
Filed: 1984-02-20
Abstract: PURPOSE:To enable a stable output to be obtained from a sensor, by interposing an eccentric boss between a shaft and a magnetic drum so as to adjust a peripheral deflection of the magnetic drum, fixed to the shaft, to be decreased. CONSTITUTION:A magnetic drum 3, in order to adjust its deflection by interposing an eccentric boss 9, intentionally formed in an eccentric shape by eccentrically dislocating its internal and external diameters by a distance delta, between a shaft 2 and the magnetic drum 3 and rotating the eccentric boss leaving the magnetic drum as relatively fixed to the shaft, is fixed to the shaft from its end by a stopper screw 10. Then the eccentric distance delta, if the internal and external diameters of the eccentric boss 9 are dislocated by a distance 50-100mum, is sufficient as an adjusting margin, and the eccentric boss 9, if it is turned as much as half a turn, enables the peripheral deflection of the magnetic drum to be decreased to zero.

Title: Catalyst device with electric heater
Inventor: SAKURAI KAZUHIRO
IPC: F01N13/02
Filed: 1994-02-25
Abstract: PURPOSE:To shorten time required for catalyst to come up to activating temperature after an engine has been started by forming a bar like electrode into a hollow pipe shape. CONSTITUTION:An energization control circuit is actuated when an engine is started, current flows within a catalyst with a heater 10 in the radial direction from an electrode 20 to a corn 9 with the electrode 20 connected to a battery, so that the catalyst with a heater 10 is thereby heated up by energization. Since the catalyst with a heater 10 is small in capacity, the catalyst is raised in temperature in a short time, so that the carried catalyst thereby reaches activating temperature. This situation causes the catalyst with a heater 10 to start catalytic action shortly after the engine has been started, so that exhaust after the engine has been started is thereby purified. Besides, the electrode 20 is bade out of a hollow heat'resistant metallic pipe, not out of a solid metallic bar. The employment of a hollow pipe shaped-electrode as mentioned above enables the thermal capacity of the electrode to be reduced to a great extent. By this constitution, the quantity of heat consumed by an increase in temperature in the electrode can thereby be reduced out of the quantity of heat generated at the conductive joint section of the catalyst with a heater 10 when the engine is started.
