Title: Picture transfer device
Inventor: TOKUNAGA HIROSHI
IPC: G03G15/16
Filed: 1984-08-21
Abstract: PURPOSE:To eliminate the color deviation of multi-colored pictures by giving the charge of a polarity same as a toner at the rear surface of a transfer material, impressing a reverse polaritly voltage to a transfer drum and attracting the transfer material so as to fix it. CONSTITUTION:For instanct, an electrostatic image is exposed on a selesium photosensitive drum 10' to form the image of a toner 9 negatively charged. A transfer drum 30 is so constituted to provide a conductive elastic layer 4 and an insulating layer 5 on a conductive basic material 3. Said transfer drum 30 is impressed by a positive bias voltage 6 and is brought into contact with the photosensitive drum 10' at a contact point A. A transfer material 10 is supplied as shown by an arrow D, and the rear part of said material is nagetively charged by a corona discharge device 7. When the transfer material 10 is entered to the contact part A of the drums 10' and 30, transfer is conducted on the transfer material 10 since the negative toner 9 is attracted to the transfer drum 30. Moreover, the negative transfer material 10 is attracted to the positive transfer drum 30 and securely fixed on the drum. Consequently, even if colors of toner are sequentially charged, the multi-colored picture without color deviation can be obtained since the transfer material is fixed on the drum.

Title: Picture reading device
Inventor: NAKAMURA SEIKICHI
IPC: H04N1/401
Filed: 1988-07-12
Abstract: PURPOSE:To reduce the influence of the dispersion of the reflection factor of an reference white surface or dust and a flow by moving a lens unit at the time of sampling a shading waveform, and reading the reference white surface as keeping it in the state of out-of-focus. CONSTITUTION:At the time of the sampling of the shading waveform, the lens unit 3 is moved by moving a solenoid 9. When the lens unit 3 is moved, since the position of a CCD line image sensor 4 deviates from an imaging position, it comes to read a reading position in the state of out-of-focus. Accordingly even if a reference white plate 5 is laden with the dust or the flaw, their influence is reduced. Besides, the variation of the reflection factor of the reference white plate 5 is reduced as well.

IPC: G01H11/08
Filed: 1994-07-27
Abstract: PURPOSE:To measure the two-dimensional spatial distribution of a sound wave with high spatial resolution by fixing a sound wave collimator having a plurality of through holes and formed out of a sound absorbing material or unit to the surface of a semiconductor substrate, and bringing sensor cells into coincidence with the positions of the holes. CONSTITUTION:For instance, a sound wave collimator 3 formed out of a sound absorbing elastic material such as rubber is adhesively fixed to the upper surface of a substrate 1 in which 25 sensor cells (FETs) 2 are arranged in a matrix. The collimator 3 has through holes 32 partitioned by a partition plate 31, and is so composed that the positions of the holes coincide with the cells 2. A sound wave from a sound source is propagated as a longitudinal wave through the air to arrive at the collimator 3, collimated by the plate 3, propagated through the holes 32 without generating reflected waves to arrive at the cell 2 of the bottom. Thus, the two-dimensional spatial distribution of the wave can be detected with high spatial resolution.

Title: Optical current/magnetic field measuring apparatus
Inventor: WATANABE MASAMI
IPC: G01R33/032
Filed: 1985-08-12
Abstract: PURPOSE:To attain a smaller type and a higher sensitivity of the equipment by a method wherein a deflection means is provided to reflect light within a magnetooptic element so that it is allowed to pass in reciprocation at the right angle to the applied magnetic field under deflection, which yield the same effect as wound be done by lengthening the optical path component along the applied magnetic head. CONSTITUTION:Light linearly polarized with a polarizer 3 comes into interfaces 9a and 9b at an angle exceeding the critical angle from the incident surface 9d, travels straight at the right angle to a magnetic field 5 totally reflecting in multiplicity alternately on total reflection surfaces 9a and 9b and put back being reflected on a multilayer reflection film 10. Then, it returns at the right angle to be magnetic field 5 being totally reflected in multiplicity on the total reflection surfaces 9a and 9b again and emitted from the emission surface 9e. The polarization plane of the emitted light rotates by Faraday effect according to the intensity of the magnetic field 5 and the length of the optical path component along the magnetic field 5. With such an arrangement, as light reciprocates within a magnetooptic element 9 by n+1/2 (n is positive number), the angle of rotation multiplies (2n+1) times larger than would with no such a multiplex reflection, thereby increasing the measuring sensitivity of current and magnetic fields accordingly.

Title: Generation system for reception timing
Inventor: KODAIRA SHIGEO
IPC: H04L7/10
Filed: 1984-08-24
Abstract: PURPOSE:To accelerate economization by limiting the operation period of a reception timing circuit to a burst reception period by using a transmission/reception switching signal outputted from a transmission timing circuit. CONSTITUTION:An intra-office circuit terminating device is provided with a gate 15 between a phase lock circuit 11 and a reception timing circuit 12' and a clock signal outputted by the phase lock circuit 11 is transmitted to the reception timing circuit 12' through the gate 16. The gate 16 is in a cutoff state during the burst transmission period wherein the transmission/reception switching signal (s) is set to a logical value 1 and turns on during the burst reception period. Consequently, no clock signal is inputted to the counter 13' in the reception timing circuit 12' during the burst transmission period, so the counter does not count and then starts counting the clock signal which is inputted for the 1st time in the burst transmission period, thereby generating various timing signals through a decoder 14. Consequently, the counted value is reduced to half as compared with the counter 13 of the conventional circuit 12 and the size is therefore reduced, thereby reducing the power consumption.

Filed: 1985-08-08
Abstract: PURPOSE:To produce an ion beam with high luminance and a large source size by using as the ion emitter a granular high-melting-point substance having a flat end surface instead of a needle. CONSTITUTION:After a substance to be ionized is placed in a reservoir 1 and a lid 3 is placed over the reservoir 1, the reservoir 1 is heated by feeding a current from a heating power supply 5 through heating electrodes 4. When the ionization substance is heated to a temperature above the melting point, the molten ionization substance passes through an emitter 2 consisting of a granular substance by capillarity and reaches the surface of the emitter 2. The emitter 2 of the above structure can be formed by sintering a high-melting- point metal such as tungsten. Due to a negative voltage applied to a lead-out electrode 7 through a lead-out electrode 8, an ion beam 9 is produced from the molten metal 6 having reached the emitter surface by electrostatic emission.
