Title: Power amplifier
Inventor: OSATO YUTAKA
IPC: H03F1/52
Filed: 1991-05-08
Abstract: PURPOSE:To stop an output transistor from deviating from a safe operating range even when a terminal at the output capacitor load side of a B-class push-pull output circuit is erroneously connected a power supply terminal. CONSTITUTION:When the terminal at the side of speaker 46 is connected to the terminal to which power supply voltage has been applied, a voltage that is a sum of charging voltage of output capacitor 45 and the power supply voltage is applied to an output terminal 44. This overvoltage conducts transistors 40 and 41, and a safe operating range detecting circuit 101 detects erroneous connection. When the transistor conducts, transistors 43 and 39 conduct, while a transistor 24 is shut off. Thus, transistors 25 and 28 are turned off, are stopped from deviating from the safe operating range, and are protected from being destroyed by erroneous connection.

The surface layer has a composition constituted by additionally incorporating 0.06-2% Ni into the composition of the inner layer. At this time, the surface layer means respective parts in the regions from the surface and the rear side surface to positions at a depth of 0.015-0.15t per side from the surface and the rear side surface, respectively, when plate thickness is represented by (t). A molten steel 11 is poured into a mold 3 via an immersion nozzle 4, together with gas downward perpendicularly. The molten steel 11 is reversed by the buoyancy of the gas and allowed to ascend as an ascending stream 12.  Since a magnetostatic field 5 suppresses the ascending stream 12, and an alloy steel, in the part higher than the magnetostatic field 5, is allowed to flow stably, a surface layer 10a into which an Ni wire 9 is penetrated is formed stably on the surface of an inner layer 11a.

Title: Radio transmitter and receiver
Inventor: KOMINAMI YASUO
IPC: H04W88/02
Filed: 1984-05-23
Abstract: PURPOSE:To control optionally both transmission and reception areas and to prevent undesired crosstalks by providing a control means to a transmitter for transmission output and a control means to a receiver for reception sensitivity. CONSTITUTION:In a circuit system S of the transmission side, a transmission control circuit 31 controls the AC gain through control of a variable resistance VR. The highest gain is obtained when the value of the VR is equal to zero. Then the gain is lowered as the value of the VR increases. In other words, the modulation output obtained from a modulation circuit 6 is controlled to an optional level by the circuit 31 and then supplied to a high frequency amplifier circuit 7 of the next stage. Then the transmission area is also controlled optionally. This reduces the crosstalks. In a circuit system R at the reception side, an attenuator 41 is provided between an intermediate frequency amplifier circuit 15 and a demodulation circuit to control the transmission of an intermediate frequency signal. In such circuit constitution, the levels of both sound and carrier signals are controlled together with the reception sensitivity of the system R. Thus the crosstalks are reduced.

Filed: 1987-04-25
Abstract: PURPOSE:To aim at enhancing engine brake by providing such an arrangement that the throttle opening degree is smoothly decreased by manipulating an accelerator pedal, and simultaneously, a shift-up or shift down of gear shift stages is evaded. CONSTITUTION:When a detecting means H detects the driver manipulating an accelerator pedal A for deceleration, that is, it detects a returning rate of the accelerator pedal, a throttle gain changing means I decrees the opening degree of a throttle valve B, more smoothly than usual, through a control means C. Further, simultaneously, a speed change pattern changing means J shifts a speed change line constituting a speed change pattern toward the high speed side, and a control means E avoids shifting up gear shift stages in an automatic transmission F, or shifts down so as to control an engine D and the automatic transmission F in a direction in which brake action is increased. Thus, it is possible to obtain a deceleration condition which satisfies the driver's demand.

Title: Power control device
Inventor: SANO TAKESHI
IPC: G05F1/66
Filed: 1990-04-18
Abstract: PURPOSE:To prevent the increase the control deviation and to control the electric energy to a desired level by providing an electric energy detector, a prescribed deviation computing means, and an internal set value computing means. CONSTITUTION:An electric energy detector 7 detects the electric energy to be controlled. A deviation computing means computes the deviation between the difference of outputs of the detector 7 set before and after a prescribed time step and the step electric energy obtained by computing the time step based on the command set value WSV at each prescribed step time. An internal set value computing means 8 computes the internal set value WSV1, i.e., the control target of a power controller 6 from the output of the deviation computing means and the value WSV. Then the value WSV1 is set at a level lower than the value WSV when the output difference of the detector 7 is larger than the step electric energy. Thus the deviation of the electric energy is suppressed. As a result, an adverse influence is suppressed with accumulation of the control deviations of a feedback control system and the power control is attained to keep the electric energy at a prescribed target level.

Title: Driving method of ink recording head
Inventor: OOBA YUUJI
IPC: B41J2/06
Filed: 1980-07-26
Abstract: PURPOSE:To prevent the breakdown of an electrode by means of electric discharge between electrodes and to decrease the number of drivers, switches, etc. by a method wherein ink is jetted from the region of a recording electrode by means of the cooperative operation of the pulse voltages applied to the recording electrode and a control electrode. CONSTITUTION:When pulse voltages each alone of which cannot make up ink jet conditions are applied simultaneously to the recording electrode 8a and the control electrode 10a, they reach ink jet conditions by the cooperation of both pulse voltages and ink 3 jets from the region of the recording electrode 8a. This relation is similar between recording electrodes 8a, 8b and the control electrode 10a, between recording electrodes 8d-8f and a control electrode 10b, between electrodes 8a-8i and a control electrode 10c. The pulse voltages applied to the recording electrodes 8a-8i and the control electrodes 10a-10c take the same polarity and the breakdown of electrodes based upon discharge between electrodes can be avoided. In a method wherein the recording electrodes 8a-8i are divided into groups and connected in common, the number of drivers including the control electrodes 10a-10c can be reduced remarkably.

Abstract: PURPOSE:To facilitate the regulation of the positions of a focal point and an irradiation by transmitting irradiating and reflected laser light by using optical fibers. CONSTITUTION:An irradiating laser light is focused by a lens 11, inputted into optical fibers 12 and transmitted.
