Title: Method for treating surface of thin ingot
Inventor: MINAGAWA MASANORI
IPC: B22D11/06
Filed: 1988-09-07
Abstract: PURPOSE:To prevent defect of flaw, etc., caused by oxide scale, etc., by applying surface treating agent on surface of solidified shell after leaving from pouring basin part to form surface layer. CONSTITUTION:A chamber 13 is set as contacting with the tail part 12 of the pouring basin part 5, and the surface treating agent 11 is blown on the surface of the solidified shell 9 from a spray nozzle 14 arranged in the chamber 13. The blown surface treating agent 11 is melted with holding heat of the solidified shell 9 and the surface layer 15 is formed on a ingot 10 after leaving from the chamber 13. By this method, as the solidified shell 9 is left from the pouring basin part 5 without any contacting with the air, the development of the scale, etc., caused by oxidizing the surface, is prevented.

Title: Brake system for rolling stock
Inventor: SASAKI SHIN
IPC: B60L7/24
Filed: 1990-08-29
Abstract: PURPOSE:To reduce the time and cost required for maintenance and inspection considerably by converting a brake command for a pneumatic brake system into an electrical amount and generating an electrical brake force corresponding to thus converted electrical amount. CONSTITUTION:When the handle of its valve 4 is operated to a normal brake band, a command operating section 5 provides a command C for switching from normal brake to electric brake to an electric brake controller 2 whereas a brake force operating section 6 provides a brake force command A representing the magnitude of brake force to the controller 2. The electric brake controller 2 then makes a judgment whether the vehicle speed is within an effective range of electric brake and if the vehicle speed is within the normal operating range of electric brake, an electric brake generating system 3 is operated effectively thus braking the vehicle. Since the electric brake controller 2 transmits an effective command B of electric brake to the brake force operating section 6, the operating section 6 interrupts provision of brake generating command to the pneumatic brake generating system 7 for its vehicle.

Title: Pattern formation
Inventor: SAKAI ITSUKO
IPC: H01L21/027
Filed: 1993-09-10
Abstract: PURPOSE:To efficiently form a fine pattern on a substrate by feeding the substrate with molecules having a functional group containing a polymer catalyst and a functional group reacting on the substrate to cause reactive adsorption and irradiating the adsorption layer selectively with a focused electron beam thereby causing selective polymerization of monomer in the adsorption layer within an unirradiated region. CONSTITUTION:A substrate 21 is fed with molecules having a functional group X containing a polymer catalyst and a functional group Y reacting on the substrate 21. Consequently, the functional group Y reacts on the substrate 21 and the molecules are chemically adsobed by the substrate 21. An adsorption layer 23 on the substrate 21 is then irradiated selectively with a focused electron beam 24 so that the functional group X is removed selectively from the irradiated region or the region is inactivated selectively. The substrate 21 is then fed with a monomer and since molecules having the functional group X containing a polymer catalyst are present in the adsorption layer 23 within an unirradiated region, the monomer in the adsorption layer 23 is polymerized gradually and selectively through catalytic function of the functional group X thus forming a desired polymer film 25.

Abstract: PURPOSE: To stabilize lubricating performance in the initial stage of operation by forming lubricating coating films of PTFE on a surface causing rolling or sliding abrasion of inner and outer rings, a surface of rolling body and a surface causing sliding abrasion of a holder of a PTFE type high polymer material. CONSTITUTION: A holder 4 is formed of a high molecular material using PTFE as a base material, and lubricating coating films 1a, 2a, 3a and 4a composed of crystalline PTFE are formed on an outside surface of inner and outer rings 1 and 2, a surface of a ball 3 and an outside surface of the cage 4. The coating films can be formed, for example, by spraying dispersing liquid of PTFE having average molecular weight not more than 5000 to a coating film forming surface or by soaking a bearing part or a finished product in the dispersing liquid of PTFE. A lubricating coating film 4a of PTFE of the cage 4 is shaven off by contact with a rolling body, and becomes lubricating powder, and this forms a rolling coating film on a raceway surface of the inner and outer rings, a surface of the rolling body or the like, and causes a lubricating action.  Since contact between the holder and the rolling body or the like is sliding contact, the rolling coating film is formed in a short time from an operation start, so that stable lubricating performance is obtained.

Title: Optical parts
Inventor: TAKEBAYASHI KAZUO
IPC: G02B1/10
Filed: 1983-11-30
Abstract: PURPOSE:To prevent the joint of optical parts from being delaminated owing to a change in temp. by forming a coating film on the joint surfaces of the optical parts except the outside edge parts thereof and adhering and fixing directly the outside edge parts of the joint surfaces to each other. CONSTITUTION:A semitransparent film 17 formed as a coating film is deposited by evaporation on the joint surface 15 of a semitransparent prism 2 except the outside edge part 16 of the surface 15. The parts 16 are therefore directly adhered and fixed without intervening the film 17 therebetween. Triangular prisms 13, 14 are thus directly adhered and securely fixed to each other. Then even if the elongation and contraction of the glass, the film 17 and the adhesive agent vary owing to a temp. change, etc., the joint strength of the edge parts 16 is strong to obviate the delamination thereof. The delamination of the internal film 17 is obviated as well. The joint of the optical parts is thus prevented from being delaminated owing to a temp. change.

Title: Drive circuit
Inventor: WATANABE HIROSHI
IPC: H03F3/20
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of a power element driven even in a case when a driver IC does not function by providing a charge controlling element between the gate and drain of a switching element MOSFET for turning OFF a power element. SOLUTION: The drain terminal and the gate terminal of N-ch MOSFET 13 constituting a driver IC 14 with P-ch MOSFET 11 are connected through a resistor R17 as a charge controlling element. When a power element IGBT 15 is in an OFF state, and the voltage of an IGBT collector terminal 16, quickly increases, a dV/dT current flows but if a driver IC 14 functions, dV/dT is allowed to escape through MOSFET 13 to maintain the gate of IGBT 15 in an OFF state without being charged. Even if a dV/dT current is generated when IC 14 does not function, MOSFET keeps an ON state by the resistor 17 to prevent the gate of IGBT 15 from being charged to keep IGBT 15 in an OFF state.
