Title: Water-dust proofing method of noncontact rotary seal
Inventor: YUZUHARA HIDEO
IPC: B23Q11/08
Filed: 1991-07-12
Abstract: PURPOSE:To provide a water-dust proofing method of a noncontact rotary seal which has a good sealing effect even at low speed rotation or intermittent low speed rotation. CONSTITUTION:A high viscous fluid is fed out of an oil hole 1b of a tool rest body 1 and fed to a labyrinth clearance 18 (less than 0.5mm) by way of an axial pressure receiving surface with two oil grooves 1a, 16b. In addition, with low speed rotation of a turret 4 and capillarity, oil is filled up in this labyrinth clearance. Since a supply of this fluid is always carried out continuously or intermittently, dirt old oil is extruded outside with fresh oil. With this constitution, a seal surface is always made into a state of being sealed with the fresh oil and, what is more, cutting fluid and chips are prevented from entering from the outside.

Title: Thermal head
Inventor: SUGIYAMA TETSUYA
IPC: B41J2/335
Filed: 1989-07-31
Abstract: PURPOSE:To obtain a thermal head, which is brought into contact excellently with an external electrode, in which no short circuit and disconnection is generated and which hardly cause trouble, by composing a base material of a heating element, a curved surface section, to which a discrete electrode for connecting the heating element is formed, and a plane section to which a discrete electrode for connection to the outside is shaped. CONSTITUTION:Heating elements 12, a common electrode 13 connected to the heating elements 12 and discrete electrodes 14 bonded with the heating elements 12 are formed onto the surface of a base material 11. The discrete electrodes 14 consist of discrete electrodes 16 for connecting the heating elements and connecting sections 17, a plurality of the heating elements 12 are shaped in parallel in the longitudinal direction, the pitches of the discrete electrodes 16 for connection to the outside are formed in size wider than those of the discrete electrodes 15 for bonding the heating elements, and the pitches of the connecting sections 17 are reduced with approaching to the discrete electrodes 14 for connecting the heating elements. The connecting sections 17 are shaped on the plane section of the base material because the incidence of light in the oblique direction on a pattern is removed on exposure in a photolithographic process and a short circuit and disconnection are prevented. The shape of the base material having a curved surface section and the plane section may be used, and even a hollow body and even a tapered plane section may also be employed.

Abstract: PROBLEM TO BE SOLVED: To prevent adverse effect on transistor characteristics by etching an insulating film slightly remaining in an isolation region along with a semiconductor substrate using an unetched insulation film as a mask thereby eliminating deterioration of film quality due to residual organic components. SOLUTION: A thermal oxide film 102 and a silicon nitride film 103 are formed on a silicon substrate 101. An opening is then made in resist 104 in an isolation region where the silicon nitride film 103 and the thermal oxide film 102 are subjected to selective etching. Subsequently, the resist 104 is peeled and etching is performed using the silicon nitride film 103 as a mask and a deep trench 106 is made in the remaining the thermal oxide film 105 and the silicon substrate 101. Thereafter, a thermal oxide film 107 is formed on the surface of the silicon substrate. Since a photoresist film is not used as a mask at the time of etching the deep trench 106, a high quality uniform thermal oxide film 107 having reduced contaminant component is formed.

The hollow shaft 3 is turned by a motor 2 to turn the stirring vanes 5 in this way, by which sewage is stirred. Air is simultaneously sucked from the air suction port by utilizing the negative pressure generated in the water area in the front end parts of the stirring vanes and is forced to flow down in the hollow shaft so that the air is released into the sewage from air release ports 5h opened at the front ends of the stirring vanes. This air is made into fine bubbles by the stirring water flow. The bubbles are eventually mixed with the sewage. The quantity of the air released into the sewage can be adjusted by adjusting the opening area of the air suction port 5H provided in the hollow shaft 3.

Title: Error correction circuit
Inventor: NAKAMURA MAKOTO
IPC: H03M13/00
Filed: 1985-09-10
Abstract: PURPOSE:To confirm simply error position of 2-bit or over by comparing a syndrome outputted sequentially from a storage device with a syndrome detected by a syndrome detection means and using an address of the storage device when the both are coincident so as to correct the bit error. CONSTITUTION:The error correction circuit inputs a received data M'(X) to a syndrome detection circuit 11 to obtain a syndrome S(X). On the other hand, a data representing an error position outputted sequentially from a counter 12 is used as an address and a syndrome S'(X) corresponding to the address is generated from a syndrome generation ROM 13. Then the syndromes S'(X) and S(X) are compared by a comparison circuit 14. When the both are coincident, the error bit of the received data M'(X) is inverted by an error bit inverting circuit 15 based on the syndrome generation ROM 13. Thus, the error correction of 2-bit or over is executed without using a complicated algorithm to simplify the circuit constitution.
