Abstract: PURPOSE:To obtain the semiconductor crystal layer of superior quality on an amorphous insulator by a method wherein, when an annealing is performed by projecting a laser beam on the semiconductor layer such as polycrystalline Si and the like, the center point of beam intensity on a sample is pluralized using a lens system, and recrystallization is started from said center points. CONSTITUTION:The laser beam emitted from a continuous oscillation type Ar ion laser light source 11 is made irradiate on a reflecting mirror 13 through the intermediary of a shutter 12 to be used for ON-OFF operation, said laser beam is reflected by a relfecting mirror 14, and it is forcussed by a lens system 15 and projected on the sample 16 located on a sample stage 17. At this time, the reflecting mirrors 13 and 14 are installed on a galvanometer respectively, and the beam is scanned in X-Y direction in a swinging manner. According to this constitution, a lens system 15 wherein a plurality of convex lenses are plane-arranged is provided in the optical path of the beam which is made incident on the sample 16, thereby enabling to generate the point having the maximum beam intensity by the help of respective lense. Thus, the recrystallization which is ordinarily starting from the circumference of the sample 16 is started from the point having maximum beam intensity.

Title: Measuring length of black rubber object
Inventor: YONEZAWA TAKESHI
IPC: G01B11/02
Filed: 1979-02-28
Abstract: PURPOSE: To measure accurately and simply the length between a pair of edge lines portion of a black object by scanning it with a reflex type photoelectric-switch which uses the light-emitting diode of a light in the red light area as a light source to detect the edge lines portion, and counting the timing pulse based on the detection signal.  
     CONSTITUTION: To measure the dimension W between two edge lines portions 13a and 13b of a black rubber object 15a, a reflex type photoelectric-switch 10 is placed at the distance L' from where it detects the shoulder surface 14 of the rubber but not the tapered surface 15a and 15b, and attached to a holder 16. A ball screw 20 is rotated by a rotary encoder 24, and the amount of movement of a nut 19 meshed with the screw is measured by counting the timing pulse. Since using a red light or a light in the red light area permits an edge of a black object to be accurately detected, an accurate measurement can be obtained.

Filed: 1986-02-07
Abstract: PURPOSE:To attain a common use of a displayer to display a sound volume level and a channel number by providing a key input device for the sound volume level and channel, an arithmetic processing means, a sound volume level adjusting means, and a display means. CONSTITUTION:When a four-bit CPU 222 knows that a key information from a keyboard 228 or a remote control receiver 229 is a sound-increasing key or a sound-decreasing key, the CPU 222 actuates a timer counter circuit 216. During the time when a sound volume increasing/decreasing key is continuously depressed (turning ON), a four-bit microcomputer 215 transmits a key information to an eight-bit microcomputer 200 at every lapsing of a prescribed time Following the above operation, the display of a sound volume level from the microcomputer 200 is performed by a seven-segment LED 231. Accordingly, only by depressing the sound volume increasing/decreasing key, the display by the LED 231 turns to be the display of a sound volume level after the increase/decrease of the volume. This display continues for 3-5sec after the key-depression is released, and thereafter changes to be the display of a channel number.

Title: Discharge lamp lighting device
Inventor: NISHIMURA KOJI
IPC: H05B41/18
Filed: 1993-02-15
Abstract: PURPOSE:To eliminate difficult points from the viewpoint of safety and the working efficiency by improving a light flux rising characteristic when a discharge lamp lighting device is restarted after power supply is restored when service interruption is caused for a short time. CONSTITUTION:When a service interruption period does not exceed a period To of an H level outputted from the third terminal of a timer IC.IC31, a transistor Q1 is not turned on when electric power supply is restored. Thereby, an electric current is not flowed to a set coil SC and a reset coil RC, so that contact points S10, S20, S1 and S2 maintain a condition just before service interruption is caused. Thereby, an igniter operated when an electric power switch S0 is closed before the service interruption is caused is operated. When the service interruption period exceeds the period To, the transistor Q1 is put in an OFF condition, and the transistor Q1 is turned on instantaneously through a capacitor C1 when the electric power supply is restored. Thereby, the contact points S10, S20, S1 and S2 are switched on the side for lighting an arc tube which is put out just before the service interruption is caused, and the igniter is switched.

Title: Laminated iron-core for electrical machinery and apparatus
Inventor: YAMANAKA KANICHI
IPC: H02K1/16
Filed: 1979-03-06
Abstract: PURPOSE:To prevent a laminater iron-core from inclining for eliminating magnetic vibrations by laminating iron cores, shifting them one by one by an equally distributed angle corresponding to a common divisor of the number of such grooves as clamp groove on stamping plates which are used to form a laminated iron-core, by using these grooves. CONSTITUTION:When an iron-core material on which the coil-winding slot, clamping groove, welding groove, iron-core arranging grooves, and so on are previously stamped comes, a pin 5 in a punch 2 for punching an outer diameter goes into a groove on the iron-core material. After the punch 2 lowers and punches the iron plate, a limit switch 8 is actuated to send a signal to a pulse motor 3, which rotates only by an angle set previously, so that through bevel gears 3a and 2a the punch 2 rotates only by an equally distributed angle corresponding to a common divisor of the number of the grooves, and since the pin 5 is in the punched iron-core, the iron core rotates by the same angle as the rotation of the punch. Thus, laminating the punched iron-cores, shifting them one by one, prevents the laminated iron-core from inclining.

Title: Waveguide type optical interferometer
Inventor: KAWACHI MASAO
IPC: G02F1/01
Filed: 1986-02-07
Abstract: PURPOSE:To set up accurately a coupling ratio with a low insertion loss by forming optical phase shifters at least on one of two optical waveguides coupling between two directional couplers so that the optical length is finely adjusted. CONSTITUTION:The two optical waveguides are constituted of quartz glass optical waveguides. Two photocoupling pars 21, 22 have quite the same constitution and form two directional couplers respectively to constitute a kind of optical interferometer. In the waveguide type optical interferometer having said constitution, it is unnecessary to set up the directional couplers 21a, 21b, 22a, 22b constituting the photocoupling parts 21, 22 accurately to 50% coupling ratio. Because the coupling ratio of the whole photocoupling parts 21, 22 can be tuned to 50% by driving the phase shifters 21c, 21d and 22c, 22d to execute fine adjustment of the optical length difference between the coupling optical paths. thereby, it is good enough to set up the coupling lengths of individual couplers 21a, 21b, 22a, 22b to 1/4 the complete coupling length or more, so that the allowable accuracy of production can be extremely loosened.

Title: Magneto-optical signal detection device
Inventor: ISOBE TAMI
IPC: G11B11/10
Filed: 1992-02-12
Abstract: PURPOSE:To obtain a good S/N by configuring a TE mode detecting section with a TE/TM mode separating section and a photodetector and a TE/TM mode detecting section with a TE/TM mode reflecting section and a photodetector. CONSTITUTION:The TE/TM mode separating section consists of a second optical waveguide 11, a third optical waveguide 12 and a coupling section 7a which couples the waveguides 11 and 12. In the section 7a, thickness of the waveguide is very gradually changed with respect to the wavelength of the light. When an incident angle alpha to the section 7a of the light flux, which is guided to the TE/TM mode separating element, is set between the respective critical angles of a TE0 mode and a TM0 mode, the light flux of the TE0 mode is totably reflected, the light flux of the TM0 mode is refracted toward the waveguide 12 and a photodetector 8 can detect only the TE0 mode which is tatally reflected. Similarly, a photodetector 9 detects both the TE0 and TM0 modes. Having this arrangement, a good S/N is obtained.
