Title: Camera
Inventor: MIYAZAKI SATOSHI
IPC: G03B9/08
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To automatically perform appropriate checking operation in the case of detecting the abnormality of photographing operation by performing the checking operation different from the specified operation of a camera. SOLUTION: A shutter unit 17 is equipped with a PI(photointerruptor) 29 being an abnormality detection means. When abnormality occurs in exposing operation, a control circuit energizes a solenoid 27 so as to open sectors 21 and 22. When specified time elapses on the condition that the output signal level of the PI 29 is in a high state, the control circuit judges it as a situation that the sectors 21 and 22 are not actuated. When the specified time elapses, the control circuit releases energizing the solenoid 27. When the specified time elapses on the condition that the output signal level of the PI 29 is still kept in a low state and is not changed, the control circuit judges it as a situation that the sectors 21 and 22 are still kept in an off-state and are not actuated.  In the case of detecting that the output signal level of the PI 29 is in the high state, the control circuit judges it as a situation that the sectors 21 and 22 are changed to an on-state and shutter operation is restored to a normal state.

Title: Method of mechanically cutting trunk of wood and side section of block and cutter head executign said method
Inventor: RAURI MIETSUTEINEN
IPC: B27B33/20
Filed: 1988-03-26
Abstract: PURPOSE: To transfer chips to a space at a side of a saw blade used in finishing, by making a diameter of a bottom of a tooth of a circular blade at a side near a chipping blade, smaller than that at an opposite side, and smaller than a rotation diameter of a point of the chipping blade by a length of one chip. CONSTITUTION: A diameter of a sawdust gap of a circular blade 3 that is, a diameter of a bottom 6 of a tooth space 5, is determined to be smaller than the rotation diameter of a point 4 of a chipping blade 2. The difference between both diameters is determined to be at least equal to a length of a chip. Whereby the cut sawdust is discharged to the void cut by the chipping blade 2 without any restriction. In ordinary cases, it is not easy for the sawdust to move in a lateral direction from a tooth space 5, so that the bottom 6 of the tooth space is inclined at an angle α in the direction of the chipping blade 2, and this inclination makes the movement of the sawdust easy. This inclination is also effective in a view point of the abrasion of the circular blade 3.  That is, the sawdust is discharged through the bottom 6 of the chip gap 5 without abrading a side part of the tooth, so that the life of the blade can be elongated.

Title: Image processing method
Inventor: KURAMOTO HIDETOSHI
IPC: H04N1/413
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To improve the compression efficiency in the case of compressing through coding processing a pseudo medium tone image obtained from a multi- value image by the error spread method. SOLUTION: When a count of a line counter 2 reaches 0, a random number generating section 3 generates a new random number R. A picture element counter 4 counts number of picture elements given to an input terminal 5 and when its count exceeds R×8-1, the counter 4 is reset to 0. An error filter 12 calculates an error En based on an error surrounded in thick black frames stored in an error memory 11 depending on a count (n) of the picture element counter 4. An adder 6 adds the error En to a multi-value picture element Pn received from the input terminal 5. A quantization error obtained by a broadcast 10 is stored in an address Xn of the error memory 11. As indicated in n=0.7 of the error memory 11 clearly, an error variance range with random number R=1 is 8-dot, in general R×8-dot.

Title: Directional coupler type waveguide optical switch
Inventor: OTA YOSHINORI
IPC: G02F1/313
Filed: 1988-03-24
Abstract: PURPOSE:To eliminate polarization dependency, to widen a permissible wavelength range, and to obtain superior crosstalk characteristics by installing electric field application electrodes on and along two channel optical waveguides which plot an S shape in a light transmission direction. CONSTITUTION:This optical switch consists of the two nearby waveguides 2 on a crystal substrate 1 and electrodes 4-7 which are provided on the waveguides in conformity with their S shape and used to apply a switch voltage. Namely, when a voltage is applied to none of the electrodes 4-7, light which is incident on one waveguide 3 transfers its light power to the waveguide 3 as it travels in the waveguide 3, and is projected from the waveguide 2. When voltages are applied to the electrodes 4-7 in cross relation, the light incident on the waveguide 3 travels in the waveguide 3 from its entrance to its exit and is projected. Namely, when no voltage is applied, the light is projected from the waveguide 2 and when the voltages are applied, the light is projected from the waveguide 3, thus switching the optical paths. Consequently, the characteristics do not depend upon incident polarized light, the permissible range of in-use wavelength variation in wide, and the crosstalk characteristics are superior.

Abstract: PURPOSE:To stabilize properties in a gradation expression with respect to the temperature fluctuations of a photosensitive body by keeping the attenuation curve of a photosensitive body potential to a light emission level almost constant. CONSTITUTION:This digital image forming device is provided with a light emitting means 31 modulating the intensity of light to the photosensitive body 41 to an input signal, and a temperature sensor detecting the temperature of the surface of the photosensitive body 41.

Thus, even if the temperature is fluctuated, gradation correcting properties are stabilized, and reproducibility for expressing gradation is improved.
