Title: Receiver
Inventor: HORISAKI KOJI
IPC: H04B17/40
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a receiver that can surely eliminated transmission channel distortion by calculating a response of the transmission channel not susceptible to the effect of a noise of the receiver itself. SOLUTION: A transmission channel response calculation section 13 calculates 1st to n-th transmission channel responses to store them to a storage section 14. A correlation calculation section 15 obtains correlation values of the 2nd to the n-th transmission channel responses with respect to the 1st transmission channel response and provides an output of the results to a transmission channel response synthesis section 17. The transmission channel response synthesis section 17 synthesizes the 1st to n-th transmission channel responses by adding a weight corresponding to each correlation value to it to obtain a synthesized transmission channel response. The synthesized transmission channel response has less effect of noise. A distortion compensation section 18 uses the synthesized transmission channel response to eliminate the distortion in the received signal.

Title: Cooling device for optical mechanism
Inventor: MATSUMURA KAIZO
IPC: G01M99/00
Filed: 2000-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a cooling device for an optical mechanism provided with a means to high-efficiently heat a refrigerant in reference to a dew point of an atmosphere in a light source so as to prevent vapor condensation from occurring in an optical mechanism. SOLUTION: Before a lamp is lighted, a second refrigerant flows a route consisting of, in order, a tank 10, a valve 5c (a flow passage runs in a direction A1), a first heat-exchanger 6, a pump 8, and a valve 5a and a secondary refrigerant is heated at the first heat-exchanger 6 and increased in temperature. When the temperature of a secondary refrigerant is increased to a value higher than a dew point detected by a dew point detector 3, a valve 5b is opened and the valve 5a is closed. This operation causes a flow of a secondary refrigerant to the light source part 1 side and heats the optical mechanism of the light source part 1. When the lamp 1a is lighted, optical parts and a holding member are heated and the temperature of the secondary refrigerant is increased in temperature.  When the temperature of the secondary refrigerant exceeds an upper limit temperature, a control part 4 switches a flow passage A2 of the valve 5c to a direction A2 and the secondary refrigerant is caused to flow through a heat-exchanger 7. This constitution cools the secondary refrigerant, which is decreased in temperature.

Title: Airtight method between joint and airtight wall and airtight joint
Inventor: MENAGE FREDERIC
IPC: F04B53/00
Filed: 2000-04-10
Abstract: PROBLEM TO BE SOLVED: To solve a problem of contamination caused by a fluid and achieve good airtightness by sufficiently deforming a joint and a support airtight wall so that unavoidable gaps on the surface are choked or closed when two soft materials are fastened. SOLUTION: A joint 5 and an airtight wall 7 are made of PTFE. The joint 5 is a washer having a nearly square or rectangular cross section, it has a groove expanded in the INT direction when a small tongue piece is arranged on the support airtight wall 7 side in the joint 5 on the INT side, and the groove does not completely traverse the whole width of the washer 5. Airtightness is promoted by the groove. A fluid clearly has two possible passages, i.e., a passage between the joint face 30 of the joint 5 and the wall face 70 of the airtight wall 7 and a passage between the inside portion 50 of a pump body 2 and the protruded end of the joint 5. When the fluid enters between the inside portion of the pump body 2 and the joint 5, the fluid intrudes the groove and tends to expand the groove for generating further airtightness.

Title: Lead pipe adaptor unit and main push device for propulsion
Inventor: MIYAJI TOSHIO
IPC: E21D9/06
Filed: 2000-04-19
Abstract: PROBLEM TO BE SOLVED: To smoothly perform the execution by a jacking method and reduce costs by preventing the damage of a screw for a lead pipe and a lead pipe adaptor unit. SOLUTION: The velocity of backward movement of a reciprocating base 53 is higher than that of the release of the screw in the case where the reciprocating base 53 are moved back in order to release the screw for the lead pipe 2 and the lead pipe adaptor unit 1. However, a spline flange 7 is relatively moved back while rotating in the axial direction of a spline shaft 9 and in the (clockwise) direction of loosening the screw in such a manner that gaps δ, γare formed between a screw adaptor 3 and a stopper 10 in order to be able to reduce the load on the screw and prevent the damage of the screw for the screw adaptor 3 of the lead pipe 2 and the unit 1. More specifically, the spline shaft 9 is moved back only by the rotation in this case because both the spline flange 7 and the spline shaft 9 can be rotated and freely moved relatively in the axial direction. The next lead pipe 2 is connected to the already-buried lead pipe 2 after the reciprocating base 53 has been moved back to the limit.

IPC: G03B27/46
Filed: 2000-04-27
Abstract: PROBLEM TO BE SOLVED: To provide an image processor which can detect with high accuracy both standard and full panoramic frames which are mixed together and recorded on a photographic film. SOLUTION: The image data equivalent to a single piece of photographic film are fetched by a scanner, and the film base density is detected from these image data.
