Title: Focus error detector in optical recorder and reproducer
Inventor: SHIMOO SHIGERU
IPC: G11B7/09
Filed: 1981-08-12
Abstract: PURPOSE:To detect focus error, by providing a 1/2 wave length plate having a positive and a negative curvature toward a condenser lens in an optial path of a reflected light of linear polarization and detecting lights through the respective 1/2 wave length plates. CONSTITUTION:A 1/2 wave length plate 17a has a negative curvature toward a polairzed light beam plitte 12, while a 1/2 wave length plate 17b has a positive curvature. A photodetector 18 is so designed that a light of linear polarization can be transmitted at the maximum strength with a polarized angle by 90 deg. to the light with linear polarization incident to the 1/2 wave length plates 17a  and 17b, and a light incident orthogonally to a curved surface of the 1/2 wave length plate best transmits the photodetector 18. Thus, the amount of light received with the photodetectors 19a and 19b is changed when the returned light  from the splitter 12 is a diffused light and a condensed light, and from this difference, a focus error detection signal 101 can be obtained.

Title: Mount structure of holder for supporting water resistant board of rise-up part of flat roof
Inventor: SAWANISHI RYOZO
IPC: E04G9/10
Filed: 1993-05-27
Abstract: PURPOSE:To efficiently embedding and fixing a rise-up part, when it is formed by placing concrete, at a desired position in a jaw of the rise-up part. CONSTITUTION:An upper holder 10 has the construction such that a water dripping member 13 which extends horizontally and then downwards is provided on either side of a member 11 with a lower opening having a U-shaped cross section adapted to receive the upper end of a water-resistant board 6. In a fixing piece 40, there is provided on the opposite side edges of a horizontal member 41 a rise part 43 for engagement with the unner surface of a suspended piece 14 of the member 13 of the holder 10, and a cut groove 42 for driving nails is formed in the middle portion in width direction of the member 13. The groove 42 is raised upwards, whereby, when a nail is driven, a hammer hits against the raised portion and hence the piece 43 on the side is not damaged. A nail can be driven until it comes into contact with the raised portion so that the piece 40 is supported stably. Since the piece 43 is fitted into the member 13, when concrete is placed, the rising up of the member 13 due to its bending is surely prevented by that engagement.

Filed: 1982-07-19
Abstract: PURPOSE:To enable to form the part of gentle inclination of an aperture and the part of steep one at the same time by a method wherein the pattern only of a region wherein gentle inclination is provided is bored through the second resist film. CONSTITUTION:A Si oxide film 2 is formed on an N type Si substrate 1. Next, a negative type photo resist film 9 of high adhesion property is formed on the Si oxide film 2. Pre-bake treatment is performed to the Si substrate 1 whereon the photo resist film 9 is formed on the Si oxide film 2, through the above-mensioned treatments. After a mask 10 whereon a fixed pattern is drawn after this treatment is arranged on the Si substrate 1, the photo resist film 9 is exposed.

Title: Detection structure for abnormality of tensioning apparatus for overhead wire
Inventor: UEISHI SATOSHI
IPC: G01L5/04
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain a detection structure by which whether the tension of an overhead wire is proper or not is always monitored, by which an abnormality can be detected at an early stage so as to take measures and which prevents the disconnection of the overhead wire by a method wherein a gas for a spring or a pressure is monitored and a change in the tension of the overhead wire is monitored. SOLUTION: When a moving cylinder 2 is pulled to the right side by an overhead wire L via a moving rod 3, a fixed rod 4 is going to rush further into a liquid chamber 2b, a gas chamber 2a is pressurized via a liquid, and proper tension is generated by a springy action due to a gas pressure against it. At this time, the tension of the overhead wire L has a constant relationship with the pressure of a gas sealed in the gas chamber 2a and of a liquid sealed in the liquid chamber 2b. P.V/T=constant. That is to say, since a pressure P and/or a volume V are changed according to a change in a temperature, the tension of the overhead wire can act in a direction in which the change portion of the volume of the gas chamber due to the change in the temperature and an amount at which the overhead wire is expanded and contracted due to the change in the temperature are offset.

Title: Electromagnetic coupling device
Inventor: OKAMOTO KIYOHIDE
IPC: F16D48/06
Filed: 1981-08-13
Abstract: PURPOSE:To decrease a decoupling time of an electromagnetic coupling device, by inverting supply voltage to an excitation coil for a very short time immediately before decoupling and removing residual magnetism after decoupling. CONSTITUTION:At decoupling of an electromagnetic coupling device 10, command signals S2, S3 are led out from a control circuit 18 to actuate switching elements 12, 13. Here electromotive force, stored in a coil 15, is absorbed by a varister 16. If this electromotive force becomes lower than power of a DC power source, a reverse excitation current of the electromagnetic coupling device 10 flows from a side of the DC power source to a side of the earth through the switching element 13, coil 15 and switching element 12. That is, in a route for the reverse excitation current to flow, a resistance element is not connected except the coil 15, and power of the DC power source is fully applied to the coil 15, then electromotive force at coupling is absorbed by the varister 16. Accorddingly, the reverse directional excitation current rises earlier.
