Abstract: PURPOSE:To simplify the positioning work of a reference line by detecting the laser light, which is transmitted from a vertical laser transmitter installed in a place having a level difference, with a laser light detection part provided to a measuring instrument having the reference line which is mated with reference markings. CONSTITUTION:A positioning device is so constituted that a base 13 for mounting a reference line transmitter is moved longitudinally and laterally until a reference line 7 transmitted from a reference line transmitter 6 installed in an optional position is sensed at the center of photodetectors 9-1, 9-2 mounted to a gate 8 mated with reference markings 10, 11 for building a standard floor and that the coincidence of said line and markings is announced by sounding a buzzer 12 when photodetectors 9-1, 9-2 are both positioned at the center. The operation for positioning the reference line for an elevator mounting device is completed by fixing the transmitter 6 after the above-mentioned announcement. The positioning operation for the reference line in place of a piano wire is thus made simple and precise.

Title: Production of liquid crystal display element
Inventor: TORIGOE TSUNEMITSU
IPC: G02F1/13
Filed: 1989-03-14
Abstract: PURPOSE:To assure and stabilize the conduction between an electrode terminal and a connector and to improve reliability by applying solder by dipping on an Ag layer formed on the electrode terminal and further slightly polishing the solder layer to flatten the surface. CONSTITUTION:Ag paste is printed on the electrode terminal 4 prior to the assembly of a cell and is calcined, for example, for 10 minutes at 500 deg.C to form the Ag layer 5 at the time of producing an LCD 1. One side end of a lower glass substrate 3 is dipped into a solder tank after the assembly of the cell and is pulled up at a prescribed speed to form the solder layer 6 on the Ag layer 5. The solder layer obt. in such a manner is built up by surface tension and, therefor, the surface is polished by 1 to 2mum and is thereby flattened after the dipping. The contact stability of the solder layer 6 and a contact point part 11a of the connector 10 is improved in this way and the insertion of the connector 10 to the LCD 1 is facilitated. The damage of the glass substrate at the time of insertion of the connector is thus averted.

Filed: 1988-03-16
Abstract: PURPOSE:To make it possible to change continuously output energy by placing a coil for giving a magnetic field within a timing adjustment cavity and giving rotation to particles within the timing adjustment cavity, thereby bringing changes in timing of particles entering a next cavity. CONSTITUTION:A timing adjustment cavity 5 and a coil 7 for giving a magnetic field in the timing adjustment cavity 5 are installed to accelerating cavities 1a and 1b. In the accelerating cavity 1a preceding the timing adjustment cavity 5, the beam track becomes straight unless current is guided to flow through a coil 7, and in the succeeding cavity 1b, the incident phase of particles is the same as in 1a and the energy gain per one cavity is also the same. Next, provided that current passed through the coil 7 is given as a pulse and its width tau is so adjusted that make particles make one turn by the magnetic field, the incident phase of particles after passage of the accelerating cavity 1b can be changed at will by choosing arbitrarily integer times that pulse width tau. With this procedure it is possible to change continuously output energy from an accelerating tube.
