Title: Window regulator device
Inventor: ISHIDA TOSHIHIKO
IPC: E05F15/16
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent an abrupt impulse acting on a material, by arranging a buffering mechanism against impulses between a window-pane and a motor, when something is caught by the window-pane at the rising motion thereof. SOLUTION: When a person or an article are caught between a window-pane and a door frame during the rising motion of the window-pane, a downward load acts on the window-pane. The load is transmitted to a tension plate 11b and a driven gear 13 is moved clockwise against the tension plate 11b while contracting a spring 20. In this case, a preset load of the spring 20 is set smaller than the sum of the weight of window-pane and the catching load. The driven gear is moved by a distance as much as the width C of the clearance 25 of the driven gear 13 and the body of the person caught thereby is detected by a detector 24. In this way, since a clearance 25 is provided between the second flange 114b and the detecting switch 24, when a load on the window-pane acts for a specified time, something caught therein can be detected.

Title: Shrunk rotor of turbine
Inventor: KODAMA HIROTSUGU
IPC: F01D5/02
Filed: 1983-12-16
Abstract: PURPOSE:To mitigate stress of a key part and prevent a crack due to stress corrosion by forming an axial gap between a key part and a wheel shrunk part and further forming a radial gap between the inner peripheral face of the fitting hole of a wheel except the key part and the outer peripheral face of a shaft. CONSTITUTION:A wheel 2 is shrunk on a shaft 3 through a shrunk part 8, while a projection 9, acting as a key part provided on an inner peripheral face adjacent to the exit of a fitting hole for the wheel 2, is inserted in the key groove 6 of the shaft 3. Then a gap 11 is interposed between an axial end face 9b of the projection 9 and the shrunk part 8, and the projection 9 axially isolated from the shrunk part 8 due to the gap 11. Further, on both sides in circumferential direction of the projection 9, radial gaps 13 are interposed between the inner peripheral face of the shaft 3. This prevents the stress generated due to shrinkage, that is, the pressure of the shrunk face, from operating on the projection 9 and concentration of the stress in the projection 9 is mitigated.

Title: Controller for pwm type power converter
Inventor: UENISHI AKIRA
IPC: H02M7/48
Filed: 1987-09-22
Abstract: PURPOSE:To prevent the increase of a switching loss and excessive high frequency generation due to the sudden change of a modulation signal without increasing the operating frequency of a power converter main circuit by controlling the absolute value of the rate of change or variation of said modulation signal to a given value and less. CONSTITUTION:A modulation signal ei is compared with the output e01 of a sample and hold circuit 18 by a comparison circuit 14. The deviation  e between them is compared with the upper limit set value KP by the comparison circuit 151 of a selection circuit 15 and at the same time with the lower limit set value -KP by a comparison circuit 152. When the modulation signal ei changes largely and suddenly, the output e01 of said sample and hold circuit 18 to be compared with a carrier signal et takes a value increasing or decreasing by KP/ t ( t is a unit time) per modulation signal ei. Therefore, when said rate of change KP/ t is set to a value which is identical with or less than the rate of change of said carrier signal et, it is possible to prevent the increase of the operating frequency of a main circuit.

Abstract: PURPOSE:To attain stable and accurate data demodulation by using a pseudo random code (PN code) so as to make a side lobe of autocorrelation function zero. CONSTITUTION:A generator for binary series signal (PN code) is constituted of PN code generators 1, 2, a correlation device 3, an exclusive OR circuit 4, multipliers 5, 6 and local oscillators 7, 8 for oscillation frequency fo. The PN code being a binary series signal at the A side uses an ordinary M series code and the PN being a binary series signal at the B side uses exclusive ORing of a clock(CLK) used for generating the M series code. Since the correlation output in this case has a waveform making the size lobe of the autocorrelation function zero, the PN code of the combination is used for spread spectrum communication. Thus, the date demodulation is implemented stably and accurately.

Title: Production of temperature sensitive ferrite
Inventor: SHIGIHARA MASAO
IPC: C04B35/38
Filed: 1993-08-30
Abstract: PURPOSE:To obtain a temperature-sensitive Mn-Zn ferrite having good homogeneity and suitable for the use as a temperature sensor by sintering an Mn-Zn ferrite molded body after it is buried, at a specified depth, in calcined powder having an identical composition to this molded body and a specific particle size. CONSTITUTION:A molded body is produced from an Mn-Zn ferrite and this molded body is buried in calcined powder having an identical composition to this molded body and a particle size of 50mum to 1mm, at the depth of >=10mm. Subsequently, this buried molded body is sintered in an oxygen-containing atmosphere to produce a temperature-sensitive Mn-Zn ferrite. This process enables the reduction of the composition variation derived from the compositional difference between the surface and the inner part of the sintered body caused by the evaporation of volatile components in the molded body. Accordingly, it is possible to produce a temperature-sensitive Mn-Zn ferrite wherein the Curie temperature has little variation and the saturated flux density has large response around the Curie temperature.

Title: Manual pump
Inventor: BURUUNO GIRUBEERU
IPC: B05B11/00
Filed: 1990-09-07
Abstract: PURPOSE: To prevent stress on the mechanism of a pump even when a push- member is in a blocking position, by disposing a freely-slidable sealing member between the smooth end of a piston and the push-member. CONSTITUTION: A push-member 3 is disconnected from the piston 2 in the upper positions of ramps 10a and 10b and blocked, and freely comes into contact with the head of the piston 2 and depresses the piston 2. Also, a freely-slidable sealing member is disposed between the smooth end of the piston 2 and the push-member 3. When a ring 9 is fitted in a cap 6, a desired orientation of a nozzle is chosen. Thus, even when the push-member 3 is in a blocking position, stress is not applied to the mechanism of the pump.

Filed: 1985-10-25
Abstract: PURPOSE:To prevent the density of an image from deteriorating after a developer is supplied into a developing container by providing a control means which rotates an electrostatic latent image carrier and a developer carrier at a high relative speed for a certain period. CONSTITUTION:A developing sleeve 11 which faces a photosensitive body 10 rotating as shown by an arrow A rotates as shown by an arrow B. Then, toner 20 in the developing container 16 is charged electrostatically by friction against the sleeve 11 and applied on the sleeve 11 by a doctor blade 12 to uniform film thickness. Further, a door opening/closing detecting device 14 is provided to a toner supply port 13 and when the supply port 13 is opened or closed, the device 14 sends an electric signal to a developing sleeve drive controller 15. The controller 15 rotates the sleeve 11 at a high speed for only the certain period right after the electric signal is received. Consequently, the charge of the toner 20 nearby the sleeve 11 is raised speedily and a stable image which has no reversal fog is obtained even right after the toner supply. The sleeve 11 returns to its normal rotating speed under the control of the controller 15 during copying operation which is the certain period later, so the toner 20 does not deteriorate abruptly.
