Title: Vacuum pump direct-coupled type generator
Inventor: ODAJIMA MITSUO
IPC: H02K7/14
Filed: 1986-10-01
Abstract: PURPOSE:To improve mechanical reliability of a generator, by mounting a brush holder, a voltage regulator and a rectifier on a support body. CONSTITUTION:A brush holder 16, a voltage regulator 17 and a rectifier 18 are first fixed to a support body 20 of non-magnetic material by a screw 21. The support body 20 is coupled with a stator 6 by a faucet joint 20a, and further a pump casing 8 is coupled with an outer circumferential portion by a faucet joint 20b. Since the support body is interposed, it is easy to dismantle the vacuum pump section and the generator body section. Also since heat generated in the vacuum pump is transmitted through the casing 8 and the support body 20 to the voltage regulator 17 or the rectifier 18, the thermal reliability is significantly improved.

Title: Wavelength conversion device
Inventor: TSURUMA ISAO
IPC: H01S5/50
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To obtain stable output by forming a wavelength converting part at a position apart from the exit face of light with the distance of equal to or larger than the thickness of a submount. SOLUTION: The wavelength conversion device having a wavelength converting part converts the basic waves emitted from a semiconductor laser device 14 into second harmonic waves having 1/2 wavelength in the inversion domain part 16 of the wavelength converting element 18 and emits the converted light. The wavelength converting element 18 is produced by forming a periodical domain inversion structure and a waveguide 17 extended along the periodical domain inversion structure on a substrate 15 consisting of a crystal such as LiNbO3 which is a ferroelectric material having a nonlinear optical effect and which is doped with MgO. The periodical domain inversion structure is produced by periodically forming a inversion domain portion 16 in which the direction of the spontaneous polarization of the crystal is periodically inverted.  The wavelength converting part of the wavelength converting element 18 is formed at a position apart from the exit face of light of the semiconductor laser device 14 with the distance equal to or larger than the thickness of the submount. Thereby, influences of the heat generated by the semiconductor laser device 14 can be neglected.

Title: Unauthorized use preventing mechanism for safe type money exchanging machine
Inventor: MASUDA KAZUO
IPC: G07D1/04
Filed: 1988-09-14
Abstract: PURPOSE:To prevent unauthorized use of a safe type money exchanging machine by an attendant who can operate the machine or other persons concerned by providing a money exchanging switch which stops a money exchanging function only without invalidating a coin sales managing means. CONSTITUTION:This money exchanging machine has a function which checks coins carried on a belt conveyor 3 by means of a sales sensor 7 for counting and managing the value of the coins and returns appropriate quantities of coins for money exchange when a power switch 13 is turned on and the operation is started at the time of starting business. Moreover, a controller 10 is programmed so that the sales management of the coins carried by a coin ranseur can be continued until the power switch 13 is turned off, while a stop lamp 18 lights and the money exchanging function is stopped in normal time when a money exchange switch 12 on the money exchanging side is set to 'stop'. Therefore, such an unauthorized action as robbery of the coins can be prevented completely.

Title: Differential pressure-measuring apparatus
Inventor: AIZAWA MAMORU
IPC: G01L13/02
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To avoid a change in characteristic because of assembling, facilitate the assembling and improve a yield by mounting a deep drawer part set to a liquid-separating diaphragm to a step part of a pressure-receiving part and forming an inner and an outer resistance welding parts by seam welding via a filler ring. SOLUTION: A deep drawer part 43 of a liquid-separating diaphragm 34 is mounted to a step part 41 of a pressure-receiving part 1B. An inside resistance welding part 36 and an outside resistance welding part 32 are formed by seam welding via a filler ring of a corrosion resistant material. The diaphragm 34 is set to the pressure-receiving part 1B. A cover flange 33 is pressed to the pressure-receiving part 1B and clamped. At this time, the deep drawn part 43 absorbs the pressing force by the cover flange 33. Therefore, an initial tension of the diaphragm 34 is not influenced, with no fear of varying a characteristic of the apparatus. Since the diaphragm 34 is directly welded to the pressure- receiving part 1B by resistance welding, the number of parts and weld points can be reduced, an assembling jig is eliminated, centering and fixation at the time of welding are facilitated.  The welding work is facilitated and costs can be reduced.

Title: Image observing device
Inventor: TSUNO KOUICHI
IPC: G02B23/24
Filed: 1982-12-29
Abstract: PURPOSE:To improve the function in the remote operation of an image observing device by expanding or contracting a bellows in the driving part at the operator's hand thereby bontrolling the position and direction of the lens and mirror in the adapter at the front end of an image fiber. CONSTITUTION:An image observing device is constituted of an image pickup part A, a transmission part B, an image receiving part C and a hydraulic driving part D. When the operator turns the driving knob 40 in the part D, a bellows shaft 43 changes axially and a bellows 42 expands and contracts. When the bellows 42 expands, an oil pessure is transmitted uniformly through the oil tube 5 housed in the flexible pipe 3 in the part B and therefore the 1st bellows 8 and the 2nd bellows 19 in the part A expand or contract. Therefore an image pickup lens 9 fixed to these bellows displaces and the spacing (d) from the end face of an image fiber 4 is adjusted, whereby the focus is matched. The remote operation is thus made easy and the function is improved.

Title: Welding position detecting device and its method
Inventor: WATANABE YASU
IPC: B23K9/127
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To detect the deviating quantity in the welding line direction of a stock being welded with high precision and to suitably correct the positional deviation by irradiating a linear condensed light beam on the groove surface of the stock to be welded and processing the groove surface image obtained by receiving the reflecting light beam. SOLUTION: A detecting operation is executed in the vicinity of the end part of the stock 12 to be welded while irradiating the linear condensed light beam 2 from a light projector 6. The result of detecting obtained in correspondence to the position (a) separated from the end part 14 in the direction without the groove, the direction (b) extremely closing to the end part 14 and the position (c) separated from the end part 14 in the direction with the groove is received and processed with a light receiving device, and image pickup pictures SA, Sb, Sc are made as a reflecting image. Image pickup pictures Sb, Sc are the groove surface image. The point in time when the angle by line segments form the image picked up becomes below the set threshold value is detected with an image processing device as the end position detecting point.  The position of the welding robot in the point in time is judged as the end position of the stock 12 to be welded. By this way, when the stock to be welded is deviated in the welding line direction, the deviating quantity in the direction is rapidly detected and the deviation is corrected.

Title: Combustion chamber of direct-injection type diesel engine
Inventor: INABA HITOSHI
IPC: F02B3/06
Filed: 1983-12-12
Abstract: PURPOSE:To improve the starting performance and to reduce generation of blue and white smokes by forming the combustion chamber of the direct injection type Diesel engine provided with a fuel injection valve having two nozzle holes into a long elliptical shape or a cocoon shape long in respective injecting directions. CONSTITUTION:The elliptical combustion chamber 1 which is long in the injecting directions of the injection valve having two nozzle holes, is formed on the upper surface of a piston 2. By taking the direction of a swor S into condideration, the injecting direction of each nozzle hole is directed to this side by an angle theta from the centerline of the elliptical form so as to be formed into an elliptical shape having a long radius L1 and a short radius L2. Since the combustion chamber 1 of a concave shape is elliptical, a turbulent flow is produced in the combustion chamber 2, and mixing of fuel spray with sucked air is promoted, and the reaching distance of the fuel spray is prolonged, thus improving the starting function and reducing the generation of blue and white smokes.
