Title: Processing method of crystal tuning fork
Inventor: WAKASUGI MAKOTO
IPC: H03H3/02
Filed: 1978-07-25
Abstract: PURPOSE:To reduce greatly the dispersion of the natural frequency and thus to increase the accuracy by extending the process length of the processed material by the amount equivalent to the length of the metal bar and then retarding the processing speed by the metal bar to decrease the warp gradually and then to arrange the length of the resonance branches. CONSTITUTION:Metal bar 6 of the soft steel, the stainless steel or the like is installed across crystl block 10 formed by piling several sheets of crystal thin plates, and then metal thin wire 3 made to thouch the block to carry out cutting. When wire 3 has a contact to bar 6, the process length of the processed material is extended by the amount equivalent to the length of bar 6. And the warp of bar 6 is decreased gradually since bar 6 features the slower processing speed due to the abrasive grain than block 10. And in case the both side faces near the groove bottom of resonance branch 11a of crystal tuning fork 11 possess the concavities and the inner surface of the groove bottom forms a concavity, the lengths of branches 11a can be made even for one process. As a result, the dispersion of the natural frequency can be reduced greatly, thus obtaining high-accuracy fork 11.

Title: Vibration actuator and its drive method
Inventor: OKAZAKI MITSUHIRO
IPC: H02N2/00
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily switch the drive characteristics of a vibration actuator by changing a pressuring force between an oscillator and a relative motion member by a pressuring mechanism in response to the frequency of a drive voltage input to an electric-mechanical conversion element. SOLUTION: An oscillator comprising piezoelectric elements 2a, 2b, 2p and 2p' as four electric-mechanical conversion elements is mounted in parallel on one of the planes of a rectangular flat-shaped elastic body 1. Also, a pressuring mechanism 24 for pushing the elastic body 1 to the surface of a rail 22 as a relative motion member with a predetermined pressuring force is mounted between the elastic body 1 and a frame 23 having a box-shaped cross section. The pressuring force between the rail 22 and the oscillator by the pressuring mechanism 24 is changed by adjusting an adjusting disk 50 by the change in a compressive coil spring 49 relative to a pressuring plate 48 in response to the frequency of a drive voltage input to the oscillator. By doing this, the drive characteristics of the vibration actuator 20 can be easily switched.

Title: Image forming apparatus
Inventor: NISHITANI SHUJI
IPC: G03G21/14
Filed: 1994-04-28
Abstract: PURPOSE:To obtain an image forming apparatus of which driving source can be made smaller than a conventional one usable and of which cost can be reduced by driving an image forming member at an operation speed at the time of starting prior to image forming operation slower than the speed in the image forming operation. CONSTITUTION:In the case of image formation, torque T1 necessary to drive a photoreceptor drum, a toner sending member, or various kinds of rollers is produced at the time when operation is carried out at frequency f1. Since a toner sometimes agglomerates when an apparatus is started prior to image formation, the torque T2 higher than the torque T1 at the time of image formation and necessary to stir and send the toner is produced at the time when operation is carried out at frequency f2. An image forming apparatus is, therefore, so composed as to be driven at frequency f2 at the time of starting to carry out starting time check and be driven at frequency f1 at the time of forming images after the toner is stirred. In this way, the maximum load torque in the normal state can be lowered and the motor cost can also be lowered by making the driving speed at the time of starting slower than that at the time of forming images.

Title: Balanced type intermediate-frequency amplifying circuit for discriminator
Inventor: SEIKE KIMIO
IPC: H03D3/16
Filed: 1979-07-17
Abstract: PURPOSE:To provide even demodulation characteristics by compensating the error of an inductance value by inserting a resistance in series into an inductance provided for corrections of demodulation characteristics. CONSTITUTION:Inductance L loaded on final stage 1 of an intermediate-frequency amplifying circuit prevents the voltage decrease of the collector bias of the stage and also resonates with a capacitance component appearing across inductance L. As a result, a decrease in gain is prevented at the low-frequency side of demodulation characteristics. Resistance R is inserted into inductance L in series and its resistance value is set adequately, so that variance in differential gain will be suppressed.

CONSTITUTION: A turning member 17 is turned, being drawn by a weight 2 that falls, sensing quakes of an earthquake, and a holding member is disengaged, letting a locking shaft 8 pop out on force of a spring 7 to a locking position and penetrate through a hole of a holed metal fixture for locking. The structure is made up in a double-row structure so that each of leaves of a double-leafed hinged door can be locked together. Thereby, articles inside the hinged doors are prevented from pushing the doors to open and falling. With cord-like matters 11, 20 for returning manually the locking shaft 8 and the turning member 17 from the locking position and a holding-release position to the original positions provided, unlocking can be made simply.

Title: Driving circuit for switching element
IPC: H02M7/537
Filed: 1992-03-17
Abstract: PURPOSE:To provide a driving circuit for switching element in which concurrent conduction of auxiliary switching elements can be prevented by connecting each auxiliary switching element with a buffer, a resistor, and a diode matching to the polarity of auxiliary switching element. CONSTITUTION:Upon transition of a control signal from zero to positive, a buffer 1' is inverted from positive to zero with no lag and an auxiliary switching element 2' is turned OFF. On the other hand, input voltage to a buffer 1 increases with a time constant determined by a resistor 5 and input capacitance 7 and reaches a threshold voltage with a slight lag. An auxiliary switching element 2, i.e., a P-type semiconductor constituted in such a manner, is turned ON with a time lag. Concurrent conduction current flowing through the auxiliary switching elements 2, 2' is eliminated because of this time lag. Consequently, heating of the auxiliary switching elements 2, 2' due to concurrent conduction is prevented, a main switching element 3 is driven positively, driving power is reduced, and efficiency is enhanced through a simple circuitry.

Filed: 1988-04-14
Abstract: PURPOSE:To perform long-term preservation in environment of corrosive gas, by arranging a trap layer having corrosiveness equal to or more than that of the magnetic recording layers of magnetic tapes to be stored at least on a part of the inner surface of a case. CONSTITUTION:The main body 1 of a case for magnetic tape cassettes is kept airtight to a certain extent by a door 2. The corrosive gas diffusing and entering from the gaps present in the case is selectively caught by the adsorptive reaction with a trap layer 1a and, even in such a case that the metal magnetic tape in the receiving case is preserved in a highly corrosive gaseous atmosphere for a long period of time, the deterioration received on the side of the magnetic tape can be held in a state causing no inconvenience from a practical point.

Title: Driver circuit for optical semiconductor device
Inventor: NAKAJIMA AKIO
IPC: H01L33/62
Filed: 1991-04-23
Abstract: PURPOSE:To realize high-speed operation of an optical semiconductor device by providing bias means having diodes and resistors to apply a pre-bias voltage across the optical semiconductor device. CONSTITUTION:When a control signal Vin to logic circuit 3 is low, one of its output terminal 3a is high, thus the base potential of a switching transistor 4 is high. On the other hand, the other output terminal 3b of the logic circuit is low, and thus the base potential of a switching transistor 5 is low. In this condition, the transistor 4 is on, while the transistor 5 is off, so that a light- emitting diode 1 is off. The forward pre-bias voltage VF1 across the light- emitting diode is determined by the ratio between bias resistors 13 and 14. The voltage VF1 is approximated by the formula shown, where VFD is the forward voltage across each of the diodes 11 and 12. Therefore, a pre-bias current IF1, determined by the formula, flows through the light-emitting diode, resulting in improved switching characteristic.
