Title: Recording and reproducing method for accompaniment signal and automatic key controller for orchestral accompaniment device
Inventor: TAKAHASHI SATOSHI
IPC: G11B20/02
Filed: 1992-05-20
Abstract: PURPOSE:To provide the automatic key controller for the orchestral accompaniment device which automatically performs key control. CONSTITUTION:When a signal is recorded on a laser disk (recording medium), a multiplied accompaniment signal W1 as the recording signal of a sine wave is additionally recorded on the laser disk in the character information period beta1 of the vertical blanking signal of a video signal and when the signal is reproduced, the signal W1 is extracted to obtain the accompaniment signal. Therefore, the accompaniment signal of the sine wave can be obtained from the laser disk. The automatic key controller for the orchestral accompaniment device detects a deviation in key from the highest frequencies of the obtained accompaniment signal and a song signal and corrects the key of the accompaniment according to the key deviation.

Title: Frequency selection system for single direction radio communication
Inventor: NAKAMA HISASHI
IPC: B66C13/40
Filed: 1990-05-17
Abstract: PURPOSE:To select a channel frequency safely and quickly by adding an identification signal specific to a receiver side to an information signal to be sent, sending the result repeatedly and setting a channel when the specific identification signal is received. CONSTITUTION:When a received specific code is unmatched with a specific code, the channel frequency is switched to a succeeding frequency, and when the specific code is matched, a display lamp is lighted and the reception channel frequency is set at that time. Then an error of a control code demodulated together with the specific code is discriminated and when no error exists, the relay corresponding to the control code is controlled and a crane 3 is activated by the operation of operation switches 11-14. Thus, when the transmission channel frequency is selected by a transmitter side 10, the channel switching is implemented automatically at a receiver 30 till the channel reaches a channel whose specific code is matched and the channel is settled in the state that the transmission and reception channel frequencies are matched.

Title: Preventing method for generation of very low frequency air vibration
Inventor: HARADA IKU
IPC: F16F15/02
Filed: 1981-08-14
Abstract: PURPOSE:To prevent the generation of very low frequency air vibration by a method wherein the phase angle of a motor is controlled so that the frequency difference of pressure fluctuations generated by the operations of a plurality of motors will not enter into the frequency range of the very low frequency air vibration. CONSTITUTION:The air vibration detected by a pressure detector (a) is fed to a minimum value decision circuit (c) through a V/F convertor 9 and a filter (b) removing air vibration elements except the one having a very low frequency. The minimum value decision circuit (c) compares sequentially the outputs of the pressure detector (a) when the phase angles of respective motors 1 are changed under a control by a program selection commanding circuit (d), and detects the phase difference of the motors 1, in which the output of the pressure detector (a) shows the minimum value. By detecting such munimum value, the revolutional phase angle preventing the generation of the very low frequency air vibration is traced automatically under controlling the phase and thus the generation of the very low frequency air vibration may be prevented.

Title: Structure for stopping jig platform in conveying apparatus
Inventor: MARUTA HIDEO
IPC: B65G47/88
Filed: 1977-10-28
Abstract: PURPOSE: To eliminate the shock of a jig platform when making contact with a stopper by forming a telescopic cylinder partially at the jig platform stopping structure and providing a shock absorber having a fluid communication hole in the cylinder.  
     CONSTITUTION: When a jig platform 2 is moved by a conveying mechanism, its end makes contact with the contact 11a of an L-shaped lever 11 to thereby compress bellows 12 to cause the internal pressure to be increased. Thus, the bellows 12 operates as a pneumatic spring so as to decelerate the jig platform 2. Simultaneously, air is ejected from a fluid communication hole 13 to eliminate the energy. Since the bellows 12 is fabricated to meet the speed and weight of the jig platform 2, the jig platform 2 is decelerated to several-tenth of the speed when making contact with the lever 11 to be collided with the stopper 3. The reaction of the collision is prevented by engaging the rear surface of a pawl 4 at the lower surface thereof with a reverse feed preventing lever 14.

Abstract: PROBLEM TO BE SOLVED: To lessen the change of a slit gap due to the temperature fluctuation by setting a specified relation between a linear thermal expansion coefficient of a piezoelectric holder set between a piezoelectric body and a base member and the installation shape. SOLUTION: A piezoelectric body 31 of a layered ceramic is installed in a plate part 4 of a slit apparatus 1 and expanded and contracted at the time voltage is applied. Levers 13, 14 in two stages formed by a cut groove 11 from the plate part 4 magnify the expansion and contract of the piezoelectric body 31 about ten time and control the width of a beam passing hole 10. The piezoelectric body 31 is installed in a base member 2 through a piezoelectric body holder 27 made of molybdenum. One end of the piezoelectric body holder 27 is fixed in the plate part 4 near the position where the inner end part of the piezoelectric body 31 is positioned, and the other end supports the outer end part of the piezoelectric body 31.  The linear thermal expansion coefficient of molybdenum is close to the linear thermal expansion coefficient of piezoelectric body 31 as compared with the linear thermal expansion coefficient of the plate part 4, so that alteration of the beam passing hole 10 due to temperature fluctuation is little.

Title: Bath device
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/46
Filed: 1995-04-28
Abstract: PURPOSE: To rapidly inject water without deviating from a new set temperature by directly using a current hot water temperature, a hot water quantity of a bath tub and the temperature of entry water when a set temperature is changed to the new set temperature and calculating a new target injection quantity. CONSTITUTION: When a set temperature is further changed, it is replaced by a new set temperature. In this case, a control part 50 reads from a memory 55 a hot water quantity in a bath tub, a current hot water temperature and the temperature of entry water which are previous data, and supplies them to a computing part 61 of injection water quantity so that a target supply water quantity corresponding to the new set temperature is immediately computed on the basis of an operation expression. Thus, the supply water quantity corresponding to the new set temperature can be computed and a control operation can be thus made the faster. Accordingly, the set temperature can be accurately changed or rechanged without making the changed set temperature different from the temperature of hot water in the bath tub obtained by the completion of water injection.

Title: Piezoelectric oscillator of temperature compensation type
Inventor: FUJII SHIYUUZOU
IPC: H03B5/04
Filed: 1978-10-20
Abstract: PURPOSE: To perform temprature compensation for the crystal oscillator with a simple constitution, by increasing the oscillation frequency through higher impedance of the diode when the temperature is decreased and by making dependent the change in the oscillation frequency on the frequeny on the frequency change in the crystal oscillator, when the temperature rises.  
     CONSTITUTION: When the temperature decreases from a given temperature, the resistance of the thermister 1 is gradually increased, the voltage to ground of the junction point 26 is also gradually lowered to increase the impedance of the diode 2. The load capacitance of the crystal oscillator 19 is changed by capacitance change in the capacitor 3 through the impedance change to increase the oscillation frequency. On the other hand, when the temperature is increased than a given temperature, the resistance of the thermister 1 is lowered, but since the impedance of the diode 2 is saturated, and the frequency change in a given temperature range is dependent on the frequency change in the crystal oscillator 19. Accordingly, the temperature compensation of crystal oscillator can be made with a simple constitution.
