Title: Peak detecting circuit
Inventor: FUTATSUGAME TAKASHI
IPC: G01R19/04
Filed: 1987-05-08
Abstract: PURPOSE:To improve detecting accuracy, by detecting the presence or absence of the output of a comparator, which is one-step higher than each comparator based on the comparison of a plurality of level reference signals and a detected peak signal. CONSTITUTION:A signal S1 as a detected peak signal, which is inputted from an input terminal 1, undergoes full-wave rectification in a full-wave rectifier circuit 21. In the detection of the peak position, the presence or absence of the output of a comparator, which is one-step higher than each of comparators 23-1-23-n is detected in the comparators 23-1-23-n in the vicinity of the peak position based on the result of the comparison with the signal S1 and a plurality of level reference signals L1-Ln by using inverter circuits 25-1-25-n and AND circuits 26-1-26-n. Even if noises are superimposed on the signal S1 and thereby the signal level is decreased, the effects are not exerted thereupon, and the detecting accuracy can be improved.

Title: Inspection method for magnetic head
Inventor: FUKAYA NOBURO
IPC: G11B5/455
Filed: 1985-05-28
Abstract: PURPOSE:To eliminate the need for a magnetic medium and to make the measurement accurate by allowing an oscillator to send an AC signal and giving the signal to a magnetic head via a transformer and applying a DC current to an erasure coil at the same time. CONSTITUTION:When an AC signal from an oscillator 15 is impressed to the primary side of the transformer 16, a signal induced in the secondary side is impressed to an intermediate tape of the coil of a read/write corer via a terminal 11d and a current flows to ground via resistors R1, R2 and a prescribed voltage is generated across the resistors. The amplitude of two signals generated across the resistors R1, R2 is entirely identical when a switch 18 is turned off. When the switch 18 is turned off, however, a prescribed DC current flows to the erase core 11b and a DC magnetic field is generated. The leakage magnetic field due to said DC magnetic field gives effect on the coil of the read/write core 11a and a difference is caused in the amplitude of the signal generated by the resistors R1, R2. As a result, a signal appears at an output terminal 12a of a differential amplifier. The result of discrimination is displayed by a light emitting diode 14 as the input to a level discriminator 13.

Title: Circuit for improving power factor of switching power supply device
Inventor: SUGITA TOSHIRO
IPC: H02J3/18
Filed: 1994-05-26
Abstract: PURPOSE:To incorporate an inverter transformer into a device with an extremely simple circuit configuration without increasing the size of the inverter transformer. CONSTITUTION:When a transistor 4 is turned on energy is accumulated in a transformer 11. When the transistor 4 is turned off, a capacitor 13 is charged. When the voltage between output terminals +V and -V of a rectification circuit 2 is lower than the voltage between the terminals of the capacitor 13, a charge current I2 of the capacitor 13 is fed to a primary coil winding 3A of an inverter transformer 3, thus charging the capacitor 13 with the separate transformer I1 from the inverter transformer 3 and hence preventing the inverter transformer 3 from becoming larger.

Abstract: PURPOSE:To relaize the use of a handset either on a wall or on a desk, by providing a hooking member in a freely appearing-disappering mode to the handset to hook the handset to the main body of a telephone. CONSTITUTION:An eccentric projection part 253 of a shift member 25 is controlled for its shift in the longer side direction of a handset 2 by means of a fixed support plate 26. While the part 253 can turn freely within a long hole 261, and accordingly the part 253 moves to the width direction of the handset 2 within the hole 261 with the revolution of a pivot. Then a shaft 252 moves in the lengthwise direction of the handset 2 within a short hole 23 along with a hook member 24. Thus a hook pawl 242 of the member 24 projects and goes back on the side face of a grip part 23 of an earphone part 21 every time the shaft 252 is turned half and then hooked again.

IPC: F28F3/04
Filed: 1984-06-01
Abstract: PURPOSE:To form the lamination type heat exchanger having a high heat transfer coefficient by a method wherein a thin plate, supported by the side surface provided in a groove, is provided with raised slotted sections to restrain the developments of speed and temperature boundary layers and coincide the direction of disturbance of flow with the direction of movement of heat. CONSTITUTION:The thin plate 10, supported by the side walls of a heat exchanging plate 12, divides a flow path 9 into two divisions and is provided with the raised slotted sections 11 while the flow of fluid is changed to the direction of wall surfaces or heat transfer surfaces and the development of the temperature boundary layer may be restrained. On the other hand, the heat transfer coefficient is increased very much at a part where the fluid collides against the wall surface and, therefore, the average heat transfer coefficient in the whole of the flow path may be improved.

Title: Fluid diode
Inventor: KOMAI HIROMICHI
IPC: F15C1/16
Filed: 1981-07-20
Abstract: PURPOSE:To enlarge the resistance ratio of a forward flow to a backward flow, by providing a disc with a plurality of guide blades on the peripheral portion of a fluid diode. CONSTITUTION:At the time of flowing forward, a fluid flows into from an inflow opening 11 and flows radially in the gap 16, then through a circular slit 15, flows into a liquid chamber 10 disposed on a disc 13 to flow out from an outflow opening 12. At the time of flowing backward, the fluid flows into the liquid chamber 10 through the opening 12. At this time, the velocity of flow decreases in the liquid chamber 10 to increase pressure of the liquid chamber 10, so that the fluid is about to flow through a gap 16 toward the inflow opening 11. At this time, the side walls of the liquid chamber 10 and guide blades 14 cause a tangential flowing in the fluid.

Title: Pcm recording and reproducing device
Inventor: OKADA SHIYOUTAROU
IPC: G11B5/09
Filed: 1979-09-06
Abstract: PURPOSE:To improve the efficiency of a tape by recording a channel discrimination signal at a fixed position while recording on the tape alternate channels of an A/D- converted signal of bits as a horizontal or slanting bit string. CONSTITUTION:At the point in time when -5V is outputted, L/R discrimination signal 6' puts magnetic head H1 into operation through recording amplifier 17 and while the initial bit of a bit string on magnetic tape 10 is magnetized to -Bmax, respective MPX data selectors 5-1, 5-2... are changed over to the left channel. In consequence, data of the left channel drive magnetic heads H2-H12 from lines L1-L12 through respective data selectors so as to magnetize 12 bits following the intial bits to +Bmax or -Bmax. Next, since L/R discrimination signal 6' outputs +5V, head H1 magnetizes the initial bit to +Bmax similarly as mentioned above and data of the right channel are sent. Thus, the width of the magnetic tape is reduced to half the conventional width and the efficiency of utilization will improve.

Abstract: PROBLEM TO BE SOLVED: To appropriately vary a deflection angle of blowing off air, by arranging air deflecting means by a Coanda effect, in a supply opening for air to the inside of a cabin. SOLUTION: A supply opening 1 has one flat side wall 2a and the other flat side wall 2b, and a drum 3a whose peripheral surface is cylindrical is rotatively arranged on this other side wall 2b centering around a fulcrum 4 by a link 5. The drum 3a is so formed that it can moved between a position where the supply opening 1 is fully opened and a position where a part of the supply opening 1 is closed. Thusly, air deflecting means H by which a Coanda effect is generated, is formed by the flat side wall 2a and the drum 3a. The peripheral surface of the drum 3a is arranged in the vicinity of one flat side wall 2a of the supply opening 1, therefore air blown off from the supply opening 1 is led to flow along the peripheral surface of the drum 3a, and as a result, the blowing off direction of the blowing off air is deflected.
