Title: Dc voltage measuring apparatus
Inventor: IKI YASUMASA
IPC: H02H3/02
Filed: 1983-01-18
Abstract: PURPOSE:To facilitate the measurement of a voltage of a pulse-like DC voltage signal random in time without a trigger signal by providing a detection circuit indicating an input timing for a signal to be measured. CONSTITUTION:When inputted into an input terminal 4, a pulse signal is detected with a detection circuit 1 to make a pulse for indicating an input timing. Then, this pulse is inputted into a control circuit 2 to make a control signal for controlling the execution of a voltage measurement. The control signal activates a measuring circuit 3 to execute the measurement of a voltage. Thus, the detection circuit thus provided for indicating the input timing for a signal to be measured facilitates the measurement of a voltage of a DC voltage signal generated random in time and in the form of a pulse without requiring a trigger signal. As the construction of the detection circuit is so simple as to be useful as level measuring apparatus of a signal generated in a burst.

Title: Air conditioning apparatus
Inventor: SHIBATA MASAAKI
IPC: F24F1/00
Filed: 1979-01-24
Abstract: PURPOSE:To prevent wind noise by providing a protrusion in the air passage at the upstream of a heat exchanger. CONSTITUTION:Cool air is introduced through an inlet 2 into a chamber 1 while being distributed to air passages 3 and 4 by a regulating door 6. The air flow in the air passage 3 tends to flow along the wall of the chamber 1 due to the linear inertia of the air and the centrifugal force applied to the air by the curved form of the air passage. A protrusion 14 formed in the air passage 3 impels the air flow toward the central part of the air passage 3 so that the air flows uniformly across the entire surface of a heat exchanger 7. Thus the air is guided to the heat exchanger uniformly over the surface without requiring any complex guide plates as used for the conventional air conditioning apparatus.

Abstract: PURPOSE:To provide a small-sized clinometer which has excellent mechanical strength and can measure the inclination over a wide angle by outputting AC voltage corresponding to the inclination angle from a detecting electrode faced to an electrode plate fitted at the tip of a cantilever vibrated by a driven piezoelectric ceramic. CONSTITUTION:An electrode plate 2 made of a springy plate and provided with a weight material 5 and an insulating plate 6 at the tip is fitted to a cantilever 1, and a piezoelectric 4 is stuck to a base section fixed to a case 8. When an AC signal is applied to the piezoelectric ceramic 4 by an operation amplifier for oscillation 11, the tip of the cantilever 1 is vibrated to the right and left. When the preset DC voltage is applied to the electrode plate 2 and a detecting electrode 3, AC voltage is generated on the detecting electrode 3 in response to the vibration of the cantilever 1 by electrostatic induction. When a clinometer is inclined by the angle theta, the tip of the cantilever 1 is bent to the left side, the distance between the electrode plate 2 and the detecting electrode 3 is widened, and the AC voltage is generated on the detecting electrode 3 in response to the inclination of the clinometer. A signal processing circuit 10 outputs the AC voltage corresponding to the inclination angle to a terminal 12.

Filed: 1994-01-26
Abstract: PURPOSE:To perform directional control for an antenna with high accuracy and stability by performing the driving control of a stepping motor by a driving pulse and a motor driving current based on a driving step. CONSTITUTION:A driving control part 10 inputs a command signal, and calculates antenna driving speed based on the command signal.

Title: Dc erasure circuit
Inventor: HARADA HISASHI
IPC: G11B5/024
Filed: 1990-01-18
Abstract: PURPOSE:To simplify constitution and to prevent an erasure rate from being lowered even when the output voltage of a power source is fluctuated by making a polarity inversion signal to flow to the coil of an erasure magnetic head by using one DC power source. CONSTITUTION:A recorded track is erased by connecting the coil 73 of the erasure magnetic head 71 to one DC power source 80 via plural switches and resistors and permitting a current whose direction is inverted alternately and whose magnitude is decreased gradually to flow on the coil 73 of the erasure magnetic head. In other words, the constitution can be simplified since one DC power source 80 is used, and also, the amplitude of the current decreasing gradually is changed accordingly even when the output voltage of the DC power source 80 is fluctuated, which generates no change of a ratio of amplitude. In such a way, a high erasure rate can be obtained.

Abstract: PURPOSE:To make the constitution of a control circuit for copying machine simple and small-sized by, by detecting the time, when a driving AC power source or a pulsating power source output approximates 0 volt, to generate a turn-on/ off signal of a load. CONSTITUTION:When the output voltage of an AC power source 10 for driving a copying machine approximates 0 volt, a transistor TR3 of a voltage check circuit 91 for full-wave rectification of the output from a transformer 14 is turned off, and a high-level output is applied to a controller 41 from the circuit 91.

Operations for other loads are similar, and respective loads are turned on similarly; and since it is unnecessary to provide a zero crossing detecting part for the purpose of preventing the noise for every driver, the constitution of the control circuit for copying machine becomes simple and small-sized.
