IPC: G02F1/03
Filed: 1986-08-30
Abstract: PURPOSE:To execute an exact phase modulation being free form a malfunction by constituting the titled modulator of a push-pull type, and impressing a voltage by which phases of light in each linear waveguide part have the same magnitude each other and become each reverse code, and a voltage before and after a part where a composite phase of each phase is inverted, to an electrode part. CONSTITUTION:The titled modulator is provided with two pieces of linear waveguide parts 13, 14 having each equal length and width between two Y branch waveguide parts 11, 12, and constituted of a push-pull type in which electrodes 15, 16 have been placed on the linear waveguide parts 13, 14, respectively. In case a voltage has been impressed between the electrodes 15, 16, when electric fields whose directions are reverse to each other and whose magnitudes are equal are generated in the linear waveguide parts 13, 14, in accordance therewith, phases of light propagated in the linear waveguide parts 13, 14 also become each reverse code and the same magnitude. Therefore, a phase (namely, a phase of light which has been synthesized and outputted as a vector by the Y branch waveguide part 12) of an output light has only one state of (omicron) and (pi), and an incomplete phase state does not exist.

Title: Marking composition for surface of high-temperature article
Inventor: OKA NORIHIDE
IPC: C09D11/16
Filed: 1983-10-31
Abstract: PURPOSE:To provide a marking compsn. suitable for use in marking the surface of a high-temperature article, perticularly steel stock, containing boric acid, diammonium hydrogenphosphate and water. CONSTITUTION:A marking compsn. contains 10-20pts.wt. boric acid, 20-40pts. wt. diammonium hydrogenphosphate and water. The ammonium ion in the compsn. increases the solubility of boric acid, improves the wettability of the surface of a high-temperature article and plays a role of keeping the compsn. neutral. When the compsn. is applied to the surface of a high-temperature article, boron phosphate is instantaneously formed from boric acid and diammonium hydrogenphosphate, whereby a white mark is formed. Since boron phosphate is molten at 900 deg.C or above to form a transparent film and the mark disappears, it is desirable to use the compsn. at 900 deg.C or below. If desired, 10-20pts.wt. high-melting inorg. pigment may be incorporated in the compsn.

Pressing on the holding part of the roller 2 is then dissolved arid the second loosening formation unit 6 is operated at the same time so that the string (S2) between the respective rollers 2 and 5 may be loosened and retained by a length required for mutually binding each end part of the string after completion of tying around the material to be bundled. The first loosened string (S1) is further fed in this state for tying around the material to be bundled.

Title: Driving circuit for piezoelectric vibrator
Inventor: OKAGUCHI KENJIRO
IPC: H03B5/32
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To function a piezoelectric vibrator with a low voltage by generating an AC voltage from a DC voltage boosted by a boosting circuit and applying the voltage to a piezoelectric vibrator element. SOLUTION: The DC voltage of a DC power source 1 is boosted by a boosting circuit 2 of a DC/DC converter and applied to an oscillation circuit 3, the AC voltage is generated and a vibrator 4 is driven. The vibrator 4 is composed of a metal such as ceramics for providing a piezoelectric body and vibration width. Then, the vibrator 4 is vibrated at a prescribed frequency by repeatedly charging/discharging electric charges of different polarities between terminals. Besides, since a current hardly flows to the vibrator 4 because of extremely great impedance and a high voltage is required for excitation, a DC voltage higher than the DC voltage outputted from the DC power source 1 by several times is provided by the boosting circuit 2. When the oscillation circuit 3 is operated with that DC voltage, the AC voltage of an amplitude almost close to the DC voltage can be provided.  Thus, vibrations greater than the oscillation due to the DC power source 1 by several times can be obtained.

Abstract: PURPOSE:To simply produce a circuit of an arbitrary combination of various resistors and diodes by using the second kind of conductive material to form the rest of a plurality of electrodes and by making the rest of electrodes pass through the second conductive type semiconductor area and contact with the first conductive type area and by forming resistor elements or diode elements. CONSTITUTION:When polycrystal silicon electrodes 18a and 18b are formed on n-type semiconductor areas 14a and 14b via contact holes on oxide silicon layer 10, the polycrystal silicon electrodes are contacted with the n<+>-type semiconductor areas 14a and 14b. However, when aluminum electrodes 20a and 20b are formed using conductive material containing aluminum, since the n<+>-type semiconductor areas 14a and 14b are thin, the electrodes 20a and 20b pass through the areas 14a and 14b and are contacted with the p-type semiconductor well 12. That is, although the p-type semiconductor well 12 on the surface of n type silicon substrate 10 and n<+>-type semiconductor areas 14a and 14b are the same in constitution, by selecting electrode material the resistor elements and diode elements can be selectively formed.

Abstract: PROBLEM TO BE SOLVED: To provide a method for surely collating the identification number of an identification card such as a point card immediately issued simultaneously with application form entry by a customer without using a special device. SOLUTION: After issuing a card 12 by a card reader-writer 10, the identification number is recorded in an identification number recording card 14 by the card reader-writer 10 and a shop clerk sticks the identification number recording card 14 to an application form 16. The identification number of the card 12 is read by the card reader-writer 10 and printed on the small piece of paper by a printer and the shop clerk sticks the small piece of paper to the application form 16. After reading the identification number of the card 12 by the card reader-writer 10, the identification number is printed on receipt paper by a POS register and the shop clerk sticks the receipt paper to the application form 16.  Since the shop clerk is not required to transfer the identification number of the application form 16, the non-matching of the identification numbers of the card 12 and the application form 16 is prevented.

IPC: H02M3/28
Filed: 1991-07-18
Abstract: PURPOSE:To enhance availability of magnetic core and to downsize a power converter in which switching elements, connected with the primary winding of a transformer having three windings, are turned ON/OFF to feed power through a rectifying/smoothing circuit connected with the second winding of the transformer. CONSTITUTION:Assuming the interval after turn ON of a main switching Q1 at time t1 before turn OFF thereof at time t2 under steady state is Ton, an input voltage V1 is applied on an input winding N1 during ON interval Ton. Consequently, a current is induced in an output winding N2 in the direction for conducting a diode D1 and a current flows through a closed circuit of N2-D1- Z-L1-N2. A voltage induced in Li at that time reversely biases on the base of a second switching element Q2 thus disconnecting the winding N3. Voltage induced in N3 also a reversely biases a diode D3. According to the invention, 100% of flux density is utilized by the use of counter-electromotive force of smoothing inductance.
