Title: Schottky gate field-effect transistor and its manufacture
Inventor: KIKUCHI KENICHI
IPC: H01L29/812
Filed: 1982-01-19
Abstract: PURPOSE:To reduce source resistance, and to obtain excellent high frequency characteristics by forming an operating layer in structure in which the surface is flat and the thickness of the operating layer between source-drain is made larger than that of the operating layer just under a gate. CONSTITUTION:Ions are implanted while using a pattern 27 formed onto the surface of a semi-insulating substrate 21 as a mask, and implanted layers 22'' are formed. The pattern 27 and a film 26 inverted are obtained by forming a metallic film 26 onto the whole surface of a sample and selectively removing the pattern 27, ions are implanted twice while using the film 26 as a mask, and the operating layer 22' is formed.

Title: X-y table
Inventor: SAITOU MIKITO
IPC: H01L21/66
Filed: 1983-01-21
Abstract: PURPOSE:To obtain an X-Y base which can move at a low speed and has small speed deviation by supporting the base via a pneumatic bearing along extended strip rails and interposing the rails between drive rollers provided at the base. CONSTITUTION:When a motor 7 is intermittently driven, a Y base 2 and an X base 3 on the base 2 integrally move through a threaded rod 6. As a result, a wafer 15 is moved in a direction Y to an optical inspection unit. When a motor 13 is continuously rotated to rotate a roller 10a coaxial with a disc 12 at a low speed, it moves along a strip rail 11 together with a roller 10b while rotating, a base 9 integrally moves, and the base 3 moves in a direction X at a low speed. The rail 11 is interposed between rollers 10c and 10d to hold the attitude of the base 3. Since the base 9 is supported on a pneumatic bearing on the base 2, it can move lightly. Consequently, the wafer 15 can be continuously moved in the direction X to the optical inspection unit. According to this structure, no problems as the accuracy and frictions of feed threads occur, the bases can be moved at a low speed with small speed deviation, thereby inspecting in high reliability.

Title: Method for prevention of fatigue of photoreceptor in electrophotographic copier
Inventor: SUZUKI KATSUMI
IPC: G03G15/00
Filed: 1980-01-24
Abstract: PURPOSE:To neutralize the carriers which are held captured in the traps in a photoreceptor and obtain stable images even after the 2nd sheet by simultaneously irradiating the light having the spectral absorption wavelength of the photoreceptor and DC corona to the photoreceptor just before charging process. CONSTITUTION:A fatigue control device 10 is provided just before a charging changer 2. This device 10 consists of a filter 12 which allows the transmission of only the light of the spectral wavelength of a photoreceptor 1 out of the light of a lamp 11, and a charger 13 which irradiates + corona of DC. The photoreceptor 1 is an insulator in the dark and can maintain + charge on the surface but when it is irradiated with the light of the spectral wavelength of the photoreceptor 1, it is a conductor and when corona charge of + is applied thereto simultaneously, it positively neutralizes the carriers fb... which had been captured in the traps (b)... after the 2nd and subsequent sheets, thereby emptying the straps (b).... Hence, even after the 2nd and subsequent sheets, + charge rides on the photoreceptor 1 in the state that the same traps (b) as those at the copying of the 1st sheet are empty, and therefore, the same surface potential as that of the 1st sheet is maintained every time.

Abstract: PURPOSE:To prevent generation of dust and to prevent seizure of a gear by sliding by mounting a disk having magnetic pole teeth coaxially to a substrate holder, disposing the magnetic pole teeth and magnets oppositely to each other and rotating the disk by the magnetic force thereof. CONSTITUTION:The disk 32 having the plural magnetic pole teeth 32a at the top end edge is mounted on the top end of a revolving shaft 27a of a substrate holder 27 pivotally supported by a bearing 26 at the front end of a rotating arm 25. Plural permanent magnets 34 are disposed along the circumferential end edge so as to face said magnetic pole teeth 32a. The disk 32 receives the rotating force so as to roll on the outside circumference of the permanent magnets 34 by the magnetic force between the magnetic pole teeth 32a and the permanent magnets 34. The substrate holder 27, therefore, makes smooth rotating and revolving motion in a non-contact state when the rotating arm 25 is rotated. The material to be evaporated evaporating from an evaporation source 23 is thus uniformly deposited by evaporation on the substrate 28.

Title: Lead-out port construction for exhaust gas in return- flow system of exhaust gas
Inventor: TANIGUCHI KOUJI
IPC: F02M25/07
Filed: 1978-01-30
Abstract: PURPOSE: To prevent a carbon from sticking, with a free carbon in the exhaust gas made not flowing into the lead-out port, by providing an orientation of the exhaust gas lead-out port in a direction against an inertia flow of the free carbon.  
     CONSTITUTION: A lead-out port 2 is constructed in a passage wall 1 so that a center axis line 2a of the lead-out port 2 and a center a center axis line la of confluent passage of the exhaust manifold may be at an acute angle of β. In this way, a turning angle, for a free carbon C included in the exhaust gas to flow into the return-flow pipe through the lead-out port 2, not only becomes bigger as compared with that as usually made but in a direction approximately in a reverse way. Consequently, the kinetic energy of inertia of the free carbon in the exhaust gas makes an action against the turning of direction to flow into the return-flow pipe through the lead-out port 2, with the in-flow motion suppressed. In such construction, a sticking of the carbon is prevented with a required effect of the return-flow maintained.
