Title: Method of automatically switching power feed route to inverter from commercial power supply
Inventor: NAGATA TAKAO
IPC: H02H7/122
Filed: 1995-04-10
Abstract: PURPOSE: To automatically restoring an inverter drive system when it is stopped because of trouble, in an induction motor drive system where both an inverter and a commercial power supply are used. CONSTITUTION: When supplying power to an induction motor 5 is stopped due to trouble of an inverter in operation, just after the stop of the inverter or after a prescribed time from the stop, an electromagnetic contactor 4 is closed and an electromagnetic contactor 3 is opened in a conjugate manner by automatic operation, to create a commercial power supply route and cut off the inverter power supply route. Next, automatic resetting of an inverter trouble closing circuit is performed. When the resetting is successfully performed, after a prescribed time limit from the resetting closing the electromagnetic contactor 3 and opening the electromagnetic contactor 4 are performed in a conjugate manner, and restoring the inverter power supply route and cutting off the commercial power supply route are performed, so as to resume the inverter driving of the induction motor 5.  When the resetting ends in failure, supply of commercial power to the induction motor 5 is continued, and an alarm of automatic trouble reset failure is issued to the outside.

Title: Video tape recorder with built-in camera
Inventor: IMAI TAKAHIRO
IPC: G10L13/00
Filed: 1990-03-29
Abstract: PURPOSE:To easily recognize the validity of switch operation by outputting a confirming tone for confirming the validity of the operation when an operation section is operated. CONSTITUTION:The video tape recorder is provided with a confirming tone generating means 10 generating a confirming tone for confirming the operation based on the operation of an operation section 7 and a voice trap circuit 5 as a confirming tone elimination means eliminating a confirming tone component from an input tone inputted from a microphone 3 at pickup. Thus, when the operation section 7 is operated and the operation is valid, a confirming tone is outputted. Since the operator confirms the validity of the operation audibly, the operability is improved and even when the confirming tone is outputted during video recording, since the confirming tone component is attenuated by the voice trap circuit 5, the tone is not recorded on a video tape.

Title: Detecting mechanism of workpiece height in three-dimensional working maching
IPC: B23Q17/22
Filed: 1992-03-05
Abstract: PURPOSE:To detect easily the height of a tool in relation to a workpiece without making the tool abut actually on the workpiece. CONSTITUTION:A pick-up 54 is arranged freely in rising and falling to a head 28 capable of rising and falling and arranged below the tip of a tool 46. Relative rising motion of the pick-up 54 to the head 28 is detected by means of a sensor 70. A distance between the bottom end of the pick-up 54 and the tip of the tool 46 is measured prior to work processing and memorized in a controller. The head 28 is lowered for detecting by means of the sensor 70 that the pick-up 54 abuts on the workpiece. As the tip of the tool 46 reaches the upper end of the workpiece by lowering the head 28 by the distance, an engraving machining of predetermined depth is applied on the workpiece by means of the tool 46 by setting the position as an original standard of a longitudinal axis.

Title: Collimator of scintillation camera
Inventor: MATSUYAMA TSUNEKAZU
IPC: G01T1/161
Filed: 1981-05-30
Abstract: PURPOSE:To reduce deterioration in a picture, by contriving an aligning position of rectangular apertures formed in a radiant ray cut-off plate. CONSTITUTION:In case a large number of square apertures 7 is formed in a radiatnt ray cut-off plate, an aligning position of the apertures 7 is set such that partitions 8 are gradually displaced in a Y-direction so that they are prevented from being aligned in one-way direction of an X-direction and Y-direction, for example, rectilinearly in the X-direction, and this forms a collimator 6. Through contrivance of the alignment position of the apertures as described above, the partition parts 8 are not aligned rectilinearly in the X-direction, whereby the shadows of the partition parts 8 are prevented from appearing in a rectilinear manner, and a rectilinear shadow appears only in the Y-direction. This permits the reduction of deterioration in picture quality due to the shadows of the partition parts 8.

Title: Evacuation method and screw type vacuum pump
Inventor: ANDO KIYOSHI
IPC: F04C25/02
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To suppress the backflow of a gas from a discharge port in high vacuum state to reduce the discharge power in an evacuation by use of a displacement vacuum pump for compressing the gas sucked through an inlet port and discharging it through the discharge port by throttling the opening area of the discharge port according to the reduction in pressure of the sucked gas. SOLUTION: When a male rotor 2 and a female rotor 3 are rotated within the rotor chamber 1a of a housing 1, a transfer chamber formed between the both is extended and contracted, so that a gas is sucked, compressed and discharged. When an evacuation is started, the slider 20a of a throttle valve 20 is pulled to the left by the effect of air pressure on the feed port 21c of an air cylinder 21 to keep the opening area of an internal discharge port 12a at the maximum. When the evacuation is progressed, and the sucking pressure is reduced to high vacuum, the slider 20a is pushed to the right by the effect of air pressure on another feed port 21b to throttle the opening area of the internal discharge port 12a to the minimum. According to this, the backflow of the gas in high vacuum can be suppressed to reduce the discharge power.

Title: Incandescent lamp
Inventor: KAWAKATSU AKIRA
IPC: H01K1/32
Filed: 1990-03-30
Abstract: PURPOSE:To utilize light of a wide angle range by containing colored metal ionic oxide in at least either high or low refractive index layer of an interference filter film comprising high refractive index layers and low refractive index layers alternately stacked one on the other. CONSTITUTION:An interference filter film 2 comprising high refractive index layers 2H and low refractive index layers 2L alternately stacked one on the other is formed on at least either one of the inner and outer surfaces of a glass bulb 1 having a filament 6 sealed therein and colored metal ionic oxide is contained in either one of the high refractive index layers 2H and the low refractive index layers 2L. Therefore the light-cut rate of the interference filter film 2 is enhanced, and even when the angle of incidence becomes greater and the cut wavelength range of the interference filter film 2 is shifted to the shorter wavelength side light of this cut wavelength range is absorbed by the colored metal ions so that lowering of the cut rate of desired wavelength range is restrained. Dependence of optical characteristics of an incandescent lamp on the angle of incidence is thereby restrained and light of a wider range of angle of incidence is used.

Abstract: PURPOSE:To form a spontaneous superlattice with good reproducibility, with good controllability and easily by a method wherein an epitaxial layer is grown in a state that the surface rearrangement constitution of growth-surface atoms during their growth operation is kept so as to have a specific structure. CONSTITUTION:The temperature of a GaAs substrate is set at 550 deg.C, and the surface of the substrate is irradiated with molecular beams of Ga, In and P. The ratio of V to III is set at 50. At this time, the growth surface of a crystal is observed by a high-energy electron-beam diffraction operation in order to confirm that the rearrangement constitution of the surface has a double-cycle structure in the [-110] direction. It is confirmed that the energy gap of Ga0.5 In0.5P which has been grown is at 1.85eV and that a spontaneous superlattice has been formed. Under growth conditions other than that, the spontaneous superlattice is always formed in a Ga0.5In0.5P crystal when the formation of the double-cycle structure in the [-110] direction is confirmed by an RHEED observation. Thereby, the characteristic of a III-V compound semiconductor film can be controlled with good controllability and with good reproducibility.
