Title: Hermetic sealing structure of optical fiber introducing part
Inventor: NAGANUMA NORIHISA
IPC: G02B6/36
Filed: 1990-02-21
Abstract: PURPOSE:To obtain the hermetic sealing structure which is less deteriorated with lapse of time by press-fitting a capillary into the front end of a metallic pipe and inserting an optical fiber into the fine hole of the capillary, then packing solder into the aperture of the front end. CONSTITUTION:A capillary press-fitting hole 6 is formed in the metallic pipe 2 and the ceramics capillary 8 shorter than the depth of the press-fitting hole 6 is press-fitted into the press-fitting hole 6. After the optical fiber 12 is passed into the fine hole of the capillary 8, the aperture 13 of the press-fitting hole 6 is packed with the solder 14. The fine hole of about 0.1mm for optical fiber insertion is easily formed in the ceramics, such as alumina, by using the ceramics capillary 8 in such a manner. Since the solder 14 is packed into the aperture 13, the hermetic sealing with the small change with lapse of time is possible. The inside surface of the press-fitting hole 6 of the metallic pipe 2 is preferably coated with gold, etc., having good wettability with solder.

IPC: H03H9/19
Filed: 1980-03-26
Abstract: PURPOSE:To obtain oscillation with excellent frequency temperature characteristics at a low frequency while making torsion oscillation is hard to occur, by arranging asymmetrically electrodes on the top and reverse surfaces of turning fork arms  of a tuning fork type quartz oscillator in the thickness direction. CONSTITUTION:Tuning fork type quartz 1 has tuning fork arms 1a and 1b; electrode (a) and electrode (c) are arranged on the top surface and reverse surface of tuning fork arm 1a, and electrodes (b) and (d) are also arranged on one flank and the other flank respectively. The other tuning fork arm 1b is similarly provided with electrodes (e)-(h). Electrodes (a) and (c), and (e) and (g) are asymmetric in the thickness direction of the oscillator. Consequently, distortion between electrodes (a) and (b) [(e) and (b)] is greater than that between electrodes (a) and (d) [(e) and (f)] and (c) and (b) [(g) and (h)], and distortion between electrodes (c) and (d) [(g) and (f)] is also greater than that between electrodes (a) and (d) [(e) and (f)] and (c) and (b) [(g) and (h)], so that torsion oscillation is hard to occur. Then, the crystal impedance is decreased and oscillation with stable frequency temperature characteristics can be obtained at a low frequency.

Filed: 1987-02-20
Abstract: PURPOSE:To improve efficiency, by making the thickness of the inner peripheral side of the oscillation transfer section of a ring-formed oscillating unit, larger than the outer peripheral side. CONSTITUTION:So far as a stator is concerned, the outer peripheral width and the inner peripheral width of an oscillation transfer section 10' composing a ring-formed oscillating unit 3' having two planes in parallel with each other are different from each other, and the inner peripheral thickness T' and the outer peripheral thickness T are also different from each other, and a firmly fitted section with an oscillating unit 3'b is processed in a plane at a fixed gradient theta so that the thickness T'> the thickness T may be set. When the stator resonates, then elliptic oscillation is generated at the surface area of the oscillation transfer section 10'. So far as a longitudinal amplitude is concerned, the gradient is constant in the outer and inner peripheral directions, and if there is a proportional relation as amplitude infinity  stator radius, the speed gradient of a pressure-frictional force generating the driving force of a rotor gets constant, and oscillating energy can be effectively used, and so a loss can be reduced. Then, the rotor and a shaft which are integrated with a slider can be rotated.

Title: Rotating speed controlling method and device for motor
Inventor: NEGISHI GIYUUJI
IPC: H02K23/36
Filed: 1982-03-13
Abstract: PURPOSE:To enable to control the rotating speed of a motor without interposing a resistor by forming a multipolar multibrush structure in a fan driving motor and selectively varying the number of conductive brushes. CONSTITUTION:When a switch S1 is closed, brushes BR1 and BR4 are conducted to start operating of a fan driving motor M. When a switch S2 is then closed, the brush BR2 is also conducted, and since the fan driving motor M is operated in the state that three brushes are conducted, the rotating speed of the fan is accelerated. When the switch S3 is further closed, the brush BR3 is also conducted, and the fan driving motor M is operated in the state that the four brushes are conducted, and the rotating speed of the fan is further increased. In this manner, the rotating speed of the motor can be controlled simply without interposing a resistor.

Filed: 1987-02-24
Abstract: PURPOSE:To permit adequate control of a toner concn. even in the case of high-speed copying by setting toner replenishment intervals by the detection output of a pseudo-batch image formed by an electric charge erasing lamp. CONSTITUTION:The pseudo-batch image region E where electric charge is made to remain is formed by putting out the part H1 of the charge erasing lamp 61 and lighting the other part H2 at timings t1-t2 on the surface of a photosensitive drum 3 charged by an electric charge electrode 8. The toner is attracted to this region and the concn. of such toner is detected. The toner is replenished to a developing part 9 when the detected output is below a prescribed value. The time until all of the stacked originals are copied is decided as one cycle and the pseudo-batch image is formed and detected before the formation of the first image in this one cycle. Since there is no need for forming the pseudo- batch image at every copying, by copying is speeded up.
