Inventor: HATANAKA HIDEKAZU
IPC: G01N21/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a safe device of low cost by irradiating the surface of a crystal with pulse laser, detecting the elastic wave generated on the surface on a rotary stage with a detector, and, while controlling output of a laser generator and rotational angle of a stage with a computer, detecting the output. SOLUTION: An Si substrate, acting as a sample 2, is provided on a stage 1. It is irradiated with pulse laser beam 5, for generating elastic wave 6. The elastic wave 6 is detected with an elastic wave detector 3. The difference between electric signal detection time of the detector 3 and irradiation time of the laser beam 5 is, as propagation time, stored together with rotational angle of the stage 1. Changing the rotational angle of the stage 1, the same operation is performed, for measuring angle dependency of the propagation time. When this cycle is repeated and the propagation time in 360 deg. is measured, since atomic arrangement of an Si surface has 4 rotation symmetry, the wavefrom containing the periodic structure of 90 deg. cycle is obtained. That is, surface azimuth is specified based on rotational dependency.

Title: Operation control circuit for dc motor
Inventor: MITSUMATA MASATO
IPC: H02P3/08
Filed: 1992-02-19
Abstract: PURPOSE:To realize smooth start/stop of a DC motor by suppressing armature current while simplifying the circuitry by reducing the number of components in the start/stop circuit for the DC motor. CONSTITUTION:A start/stop signal is fed to a field switching means to operate an armature switching means after a field current is supplied and an armature current is supplied upon elapse of operation lag time of the armature switching means thus suppressing the armature current at the time of starting a DC motor. A circuit communicating between the armature switching means and a field regulating means while bypassing the field switching means is also provided so that field current supply is sustained even if the field switching means is interrupted by a stop signal. Since a field winding has higher inductance than the armature after interruption of armature current, circulation of field current is sustained even upon extinction of armature current. Furthermore, a maximum field current command is fed to the field regulating means at the time of starting or stopping in order to suppress armature current more effectively.

IPC: B29C53/20
Filed: 1988-02-13
Abstract: PURPOSE:To reinforce a board in its slant direction and to eliminate joint line on the board surface by making a belt shaped material into a cylindrical tube in helically winding and then making this flat to join the inner surfaces thereof to each other, and by joining another board material to at least the one surface of the board material obtained. CONSTITUTION:The belt-shaped material (1A) is wound helically so as to be a cylindrical pipe (2A). In this example, a duplex tube is made because the belt shaped material is superposed at each halve and then the duplex tube is made flat. An assembly of three bending rollers, preferably a diameter defining roller are arranged so as to mold the belt-shaped material (1A) to be a helical shape, and it is preferable that the process for making the cylindrical tube to be a flat may be employed in compression by for example an assembly of press instruments. At this time, any methods should be taken whether a material with joining property is inserted into the inner part, an adhesive is applied on the inner surface or the flat material is raised in its temperature. In the case where the composite board material is worked into the board material without any joint lines, another board material without joint lines should be joined to the board surface. By this constitution isotropic property can be improved and the composite board material reinforced in its slant direction can be obtained from the narrow and the few number of an original board.

IPC: G03G15/00
Filed: 1983-03-01
Abstract: PURPOSE:To prevent dehumidifying heater from being electrified even when a switch is turned on by mistake in a paperless state and thereby to save electric power by allowing the dehumidifying heater to be electrified only when the paper is preset together with stopping power supply to the dehumidifying heater when there is no paper. CONSTITUTION:When there is copy paper 2 on a table 3 of feed paper stand, a feeler 5c is rotated counterclockwise due to self-weight of the copy paper 2 and a screen board 5b is detached from a sensor 5a. As a result, the sensor 5a turns ON, bringing the input terminal on one side of an NAND circuit to 5V. On the other hand, since the input terminal on the other side is maintained at the same level as d.c. power supply 5V because of the main switch 9 turned ON, the output becomes zero V. Then, a transistor Q at the following stage turns ON, impressing the output from the 24-V terminal of the d.c. power supply unit 11 to SSR of a dehumidifying heater driving circuit 13. As a result, the SSR is operated, connecting a commercial power supply 8 to a dehumidifying heater 4.
