Title: Recording material
Inventor: ASANO MAKOTO
IPC: B41M5/155
Filed: 1980-09-02
Abstract: PURPOSE:To prevent the fouling of the ground of a recording sheet by using a specific substituted phenol derivative compound as a developer for a recording material. CONSTITUTION:A colorless or light-colored color former and a color developer are mixed and ground to prepare a dispersion. In this case, a specific substituted phenol derivative compound of the formula (where R1, R2 and R3 are each H, a halogen atom, or a C1-C8 alkyl group), e.g., 2-(4-hydroxyphenyl)-2-(4'-aminophenyl) propane, etc., is used as a developer in a recording paper. A combined use of the developer with a black color dye, e.g., 3-diethylamino-6-methyl-7-anilinofluoran, etc., gives a particularly raised thicker color-developing effect. In this case, 1- 95pts.wt. developer is used on the basis of 1-15pts.wt. color former and 1- 40pts.wt. binder. In the recording material thus obtained, less fouling occurs in the ground and also the degree of natural coloring under a high temperature and humidity conditions is also less.

IPC: H03K19/14
Filed: 1984-06-12
Abstract: PURPOSE:To obtain the titled optical logical circuit which includes an optical AND circuit by providing at least two 1st optical waveguides, the 2nd optical waveguide, at least two photoelectromotive force elements, at least two Mach- Zehnder type optical waveguides, and at least two couples of electrodes. CONSTITUTION:When a voltage generated by a photoelectromotive force 21 is applied to an electrode 23, part of an optical waveguide part 31 where an electric field is applied varies in refractive index and the phase speed of right propagating there varies. The applied voltage, i.e. the generated photoelectromotive force of the photoelectromotive force element 21 is adjusted previously so that the phase difference between light waves propagating in optical waveguide parts 31 and 32 is set exactly to 2mpi (m: 0 or positive number) when both light waves meet each other at a conflux point. Consequently, the light waves propagating through the optical waveguide parts 31 and 32 are multiplexed at the conflux point in in-phase relation, so that light with nearly the same power as light inputted to the Mach-Zehnder type optical waveguide 30 is outputted from this optical waveguide 30.

Abstract: PURPOSE:To suppress direct current, by varying the short-circuiting-proof period of a positive side arm and a negative side arm, according to the polarity of the direct current of each phase. CONSTITUTION:An inverter 1 is PWM-controlled based on the output signal of the output signal of a micro-processor 6 which is PWM-modulated by a PWM generating circuit 5, and its output is fed to an AC motor 2. Into the processor 6, motor current is taken in every sample period via a two-phase converter 4 through the detectors 3U, 3V of the current. The processing section of the processor 6 is composed of a differentiating circuit 20, a DC component arithmetic circuit 21, a two-phase/three-phase conversion circuit 8, an output voltage command circuit 7, and adders 9U-9W. Through the difference of the two-phase AC flow of inverter output current, the scale of direct current is detected, and according to the scale, pulse width is changed, and in the output voltage of the inverter 1, DC voltage component is contrived not to be included. As a result, an output voltage distortion along with a short-circuiting-proof period can be perfectly compensated for.

Title: Method for controlling pll circuit
Inventor: MORIYAMA YOSHIAKI
IPC: H04N5/956
Filed: 1987-05-19
Abstract: PURPOSE:To contrive to stabilize the synchronization of a PLL by applying an amplitude limiting to a phase error within a prescribed range if the phase error of a regenerative horizontal synchronizing signal exceeds the prescribed range in using the regenerative horizontal synchronizing signal separated from an FM regenerative video signal as an object of synchronization while a PLL circuit locks thereto. CONSTITUTION:In throwing a selector 21 to the position (b), when it is discriminated to be locked to the regenerative horizontal synchronizing signal, a control circuit 20 allows a limiter 25 to apply amplitude limit and keeps monitoring the output of a phase comparator 22. When the PLL uses the regenerative horizontal synchronizing signal as an object of synchronization and is synchronized therewith, no large phase error is caused in the phase comparator 25. In case caused, because it is due to a dropout not being detected, the limiter 25 limits it. That is, if the phase error reaches a value being the upper limit or over or the lower limit or below the range of the amplitude limiting, the error is replaced respectively by the upper limit or the lower limit thereby preventing a large phase error from being given to a loop filter 28, then a large fluctuation in the oscillated frequency from a VCO 30 is prevented.
