Patent JP-H07120633-A (JP)
Title: Manufacture of optical waveguide element
Inventor: HATORI MASAMI
IPC: G02B6/13
Filed: 1993-10-25
Abstract: PURPOSE:To simplify the process and reduce the working cost by cutting and polishing a crystal ingot to form a crystal base having a prescribed form, and subjecting the crystal base having the prescribed form to proton exchange treatment. CONSTITUTION:A crystal ingot 9 is cut and polished to form a base 10. In this stage, the base 10 is formed into a prescribed form finally determined in an optical modulator by working all faces including both end faces 10a and 10b. The resulting base 10 is dipped in an acid 5 stored in a crucible 4 to perform proton exchange treatment. The base 10 is then annealed at 300-450 deg.C in the air for about 1 hour, and an EOG electrode 13, a light incident linear diffraction grating 14 and a light emitting linear diffraction grating 15 are finally formed to form a device. Since it is sufficient to provide the process for cutting and polishing the crystal into the prescribed form only once prior to the proton exchange treatment, the process is simplified, thereby the working cost can be reduced.

Title: Control device for automatic wiper of raindrop sensitive type
Inventor: SHIMIZU YUKIHIRO
IPC: B60S1/08
Filed: 1988-10-21
Abstract: PURPOSE:To make wiper control in good response to actual precipitating situation and the feeling of human being by judging the amount of rainfall on the basis of the counting value including not only the number of raindrops but their size, and thereupon controlling operation of the wiper. CONSTITUTION:Variation in the electrostatic capacitance because of attachment of raindrops to a raindrop sensor 1 is emitted as output in the form of variation in the oscillated frequency. This variation in the oscillated frequency appears in the output of a phase comparator 3 in a PLL circuit 2 in the form of a differential pulse signal. At this time, the pulse width of this differential pulse signal increases with change in the oscillated frequency. Larger dia. of raindrops causes larger variation in the electrostatic capacitance, which gives a larger change in the oscillated frequency to lead to a differential pulse signal with larger pulse width. Accordingly every time raindrop is attached to the raindrop sensor 1, the pulse width of the differential pulse signal is measured by a means 5, the result wherefrom is put in cumulative calculation one by one. On the basis of this counting value, operation of a wiper motor is controlled by a means 6.

Title: Operation circuit
Inventor: NAKAMURA TOSHINORI
IPC: H01H47/00
Filed: 1992-10-06
Abstract: PURPOSE:To improve the reliability of an operation circuit. CONSTITUTION:When a breaker for operation is at a connected position, a test position switch 3 is turned off, a connecting position switch 4 is turned on, and contact monitor relays 14 and 15 are respectively kept in non-excited state and excited state. If a power supply is normal, a power supply monitor relay 16 is in excited state and, therefore, a contact 16a is kept closed. Also, a time delay reset contact 14a is kept close, an instantaneous operation contact 14b is kept open, another time delay reset contact 15a is kept open, and an instantaneous operation contact 15b is kept close. If the connecting position switch 4 is in poor contact state, the relay 15 turns into non-excited state and the contact 15a is reset to close. As a result, a signal is outputted externally to give an alarm. Furthermore, if the switch 3 is in improper shortcircuit state, the relay 14 turns into excited state and the contact 14b closes, thereby outputting an external signal similarly.
