Abstract: PURPOSE:To obtain a copper plated laminar board which is excellent in moisture resistance, soldering heat resistance, and productivity by a method wherein a steel belt coated with ultraviolet setting resin is preheated, semi-cured ultraviolet setting resin on the steel belt and semi-cured ultraviolet setting resin on a copper belt are bonded together by pressure to form a laminated board of three-layered structure, which is heated to cure the semi-cured resin. CONSTITUTION:A ultraviolet setting resin 3' is applied onto a steel belt 2 with a roll coater 3, and the insulating resin is made semi-cured through an ultraviolet irradiation device. The steel belt 2 is preheated in a far-infrared ray oven 5 and bonded by thermocompression to a copper foil belt 7 provided with semi-cured insulating resin which is delivered from a copper foil 6 coil through a hot roll 8 to constitute a three-layered structure 9 composed of a copper belt, a insulating resin, and a copper foil belt. In succession, the laminated board 9 is cut into laminated boards 11 optional in length by a cutter 10 as it is bonded together by thermocompression, the laminated boards 11 are stacked up in a heating oven 13 and heated without being pressed as they are kept in a free state to form the thermally cured resin layers by fully curing insulating resin.

Title: Branch repeater
Inventor: SHIDARA TSUNEO
IPC: H04B3/38
Filed: 1979-07-24
Abstract: PURPOSE:To avoid the useless power consumption by securing the power supply only in case the signal transmitter/receiver is connected to the branching direction. CONSTITUTION:Branch repeater 1 is inserted into every place of installation of signal transmitter/receiver 7, and at the same time main communication channel 5 is provided by the route connecting all transmitters/receivers in the shorteset distance with use of repeating connector 8. Then the repeating output of branch repeater 1 inserted to the furthest end is connected to terminator 1 incorporated into repeater 1 to give the termination to channel 5 via signal short circuit line 10. In case transmitter/receiver 7 is connected in the branching direction of repeater 1, distributing connector 12 is used to secure the connection between channel 5 and branch inserting amplifier 2 incorporated into repeater 1 via line 10. At the same time, the connection is given between branch communication line 6 between repeater 1 and transmitter/receiver 7 and power supply line 4 from transmitter/receiver 7 to repeater 2. In such constitution, amplifier 2 is independent from channel 5 as long as transmitter/receiver 7 is not connected to the branching direction of repeater 1. And accordingly, no effect is given to channel 5, and furthermore no power supply 4 is given to avoid the useless power consumption.

Title: Cargo handling vehicle provided with receiving block lifting gear
Inventor: SAEKI HIROAKI
IPC: B60P1/44
Filed: 1986-04-23
Abstract: PURPOSE:To prevent a door or the like from being damaged by a tail gate by approximating a rear edge of the tail gate to an edge of a load box with the same level, dispensing with a gangplank, while stopping the upward motion of a receiving block lifting gear at a time when a door of a rear body is closed. CONSTITUTION:At the time of lifting a tail gate 17 upward by a driving source, when a door 3 is closed, a contact 21 of a limit switch 20 installed in a tension link 14 comes into contact with the contact member 30 installed in the door 3. In consequence, this limit switch 20 comes off, so that the driving source is stopped and lifting motion of the tail gate 17 is also stopped. On the other hand, in the state that the door 3 is opened, even if the tail gate 17 goes up, the limit switch 20 is left turned on intact without contacting with the contact member 30. Therefore, the tail gate 17 continues to go up and then it stops at a spot where a top surface of the tail gate 17 is flush with a floor surface of the load box 1 and a rear edge 18 of the tail gate 17 is approximated to an edge 10a of the floor surface 10.

Title: Liquid crystal display device
Inventor: SOMEYA RYUICHI
IPC: G09G3/36
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To suppress an apparent tone change and to enable the execution of a low power consumption operating mode and the expansion of contrast and bright control ranges or the like by correcting the disturbance of tone caused by light source emission spectrum fluctuation by a liquid crystal panel part by changing liquid crystal impression voltage characteristics corresponding to light source luminance output switching. SOLUTION: The data of high luminance state are written in look-up tables(LUT) 28, 30 and 32 and the data of low luminance state are written in LUT 29, 31, and 33. When the luminance of a light source 20 is switched through a light source control means 19 by a microcomputer 118, at the same time, switching means 22-27 are changed over while being interlocked. Namely, in the high luminance state of the light source 20, the LUT 28, 30 and 32 are selected by the switching means 22-27 but in the low luminance state of the light source 20, the LUT 29, 31 and 33 are selected. As a result, the tone change caused by the change of RGB chromaticity points with the luminance switch of the light source 20 is corrected by switching the LUT 28, 30 and 32 and the LUT 29, 31 and 33 and the apparent tone change can be suppressed.

Title: Power transmitting method for front wheel of vehicle
Inventor: TAKAHASHI SEIICHI
IPC: B60K17/348
Filed: 1989-04-14
Abstract: PURPOSE:To easily change to fit either specification and dispense with a drastic change of design by selectively running on either front wheel power cut off to cut off power transmission to front wheels or speed increasing drive to drive front wheel at a larger peripheral speed than that of rear wheels, at turning. CONSTITUTION:In a vehicle of specification to drive front wheels 7 at a twice speed at turning, a gear case 62 provided with a speed increasing mechanism 68 is mounted on the bottom wall 46 of a mission case 4. When a handle 5 is operated to the left at turning, the front wheel 7 is moved around a king pin. When the front wheels reach the steering angle, by action of a sensor 25 a control means 75 gives a command to a solenoid 72 to supply working oil to hydraulic clutch 36 with a solenoid valve 71 and the clutch 36 is in. Consequently, a tractor can quickly turn with a small radius, by driving the front wheels 7 at almost twice speed of the rear wheels 8. For cutting off power transmission to the front wheel 7 and driving the vehicle by independent action of the rear wheel 8 at turning, a cover 61 is mounted instead of the gear case 62. Then, even if the sensor 25 is on at turning, power transmission to the front wheel is cut off because of no speed increasing mechanism 68.
