Title: Device for braking shutter
Inventor: TOYODA YASUHIRO
IPC: G03B9/36
Filed: 1987-01-14
Abstract: PURPOSE:To prevent a trailing curtain from bending by increasing initial braking for a shutter leading curtain and increasing braking force gradually from small initial braking for the trailing curtains. CONSTITUTION:When a leading curtain driving lever 9 is released from being locked by a hook part 9c, it is rotated clockwise by a spring 11 to put a leading curtain group 3 in opening operation. Then, a trailing curtain driving lever 10 is released from being locked by a hook part 10b to places a trailing curtain group in closing operation by a spring 12. When a curtain run almost comes to the end, the lever 9 abuts on a leading brake lever 16 by a pin 9a and is reduced in speed by friction and elasticity. Then the pin 9a of the lever 9 abuts on the arm part 25a of a leading brake lever 16, so that tapered parts 25b and 25c receive braking force gradually by leaf springs 26a-26c and are reduced in speed. Then the lever 9 stops by abutting on stopper rubber 24 and then the lever 10 stops the abutting on stopper rubber 29. Consequently, the braking force is made various to prevent the trailing curtain from flexing.

Title: Power supply for vehicle
Inventor: MATSUI FUJIO
IPC: H02J1/00
Filed: 1994-01-25
Abstract: PURPOSE:To enable non-contact power supply to a low voltage load resistor from a high voltage power supply that generates high-frequency alternating current by connecting a constant-current inverter to the high-voltage power supply; the output of the inverter to the primary circuit of a transformer; and the low voltage load resistor to the secondary circuit of the transformer through an input line. CONSTITUTION:Electric power generated on a high-voltage generator 12 is rectified into a high DC voltage, which is then converted into constant-output high-frequency current on a constant-current inverter 14 and is outputted from an output line 14a. The current induces an electromotive force, e.g., 12V across an input line 16a constituting the secondary circuit of a transformer, thereby supplying power from the high-voltage generator 12 in non-contact state. This eliminates a need for connectors and simplifies wiring, facilitating safety design.

IPC: G01N23/203
Filed: 1978-01-25
Abstract: PURPOSE: To promptly meter the thickness of a film on a sample by metering the intensity of an electron beam irradiating the sample and the intensity of the reflected electron beam therefrom to obtain the mean atomic number of the sample having a thin film.  
     CONSTITUTION: A center control circuit 17 controls a sample moving mechanism 16 so that an electron beam from an electron gun 4 may irradiate a Faraday gauge 12 attached to a sample holder 7. The output of the Faraday gauge 12 is stored through an amplifier 13 in a signal converting circuit 11. While maintaining the irradiation current constant, the sample moving mechanism 16 is driven to irradiate an object sample region with the electron beam. The signal converting circuit 11 accomplishes division between the current level of the electron beam reflected from its detector 9 and the current level for sample irradiation stored so that the mean atomic number of the sample is obtained and fed to a film thickness metering circuit 14. In these ways, by introducing the acceleration voltage for sample irradiation and the means atomic number into the circuit 14, the thickness of the thin film 2 of the sample 1 can be obtained and displayed in a display device 15.

Title: Measuring method of wetting speed of powder
Inventor: IWATA HIROYUKI
IPC: G01N13/04
Filed: 1982-01-20
Abstract: PURPOSE:To measure the wetting speed of powder by liquid by packing powder samples in a cylindrical body, bringing the bottom part thereof into contact with liquid, and detecting the ascending speed of the liquid from the change in the resistances between the electrodes provided at required intervals in the cylindrical body. CONSTITUTION:Powder samples are beforehand packed in a cylindrical body 1 to form packed layers 2, and after the time feed of a pen recorder 9 is started, the liquid level in a vessel 4 is moved upward until liquid 5 contacts the powder layers 2. When both contact, a lamp is lighted in a detector 8 and the start is confirmed. When the liquid ascends by capillarity, the electric conductivities between the electrodes provided at every required interval in the body change and the output voltage for the recorder increases by every specified graduation. A stepwise graph is plotted on the recorder. If the graph is redrawn to a smooth curve, the relations between the front line position of the liquid and time are made continuous; therefore, the ascending speed of the liquid in each position is obtained by operations such as graphical differentiation.
