Title: Mark read system
Inventor: IIZUKA YOSHIO
IPC: H04N1/32
Filed: 1978-11-10
Abstract: PURPOSE: To prevent error address recognition with improved detection precision of address marks by providing reference marks at constant intervals and several address mark items between reference marks and then by discriminating whether reference marks and address marks are correct.  
     CONSTITUTION: Optical mark read from 1 is provided with reference marks M 1 ∼ M 5  at constant intervals in a facsimile scanning direction and between adjoining reference marks, several address mark entry items NA∼NH are also provided. This mark entry form 1 is scanned by scanner to detect reference mark position and addresses at address mark positions from reference marks. Further, mark inhibition regions of prescribed width are provided before and behind reference marks and the mark width is checked to make a decision on whether it is a reference mark or not; and a decision on whether an address mark is correct or not is made judging from the number of reference marks detected by sequentially detecting reference marks following a reference mark at the leading edge at fixed periods. Consequently, even if address would increases in number, error recognition can be eliminated and an accurate decision on an address can be made at any time.

Inventor: TOMITA SATORU
IPC: G05D23/24

Abstract: PURPOSE:To simplify a device by using a beam position detecting element as a synchronous detecting element. CONSTITUTION:A light intensity I of a spot SP of a deflected laser beam which a light receiving face 5-1 of a beam position detecting elements 34 has a bellshaped distribution. When this spot SP is moved across the light receiving face 5-1 in the X direction, the output of the beam position detecting element 34 is different by the position where the center of the spot SP traverses the Y axis, and consequently, the position on the Y axis which the spot SP traverses is detected by the output of the beam position detecting element 34. If the light receiving face 5-1 of the beam position detecting elements 34 is allowed to correspond to the main scanning direction of the deflected laser beam, the Y direction of the light receiving face 5-1 corresponds to the subscanning direction, and the variance of the output of the beam position detecting element 34 corresponds to that of the wavelength of emitted light in the semiconductor laser.

When the substrate is to be cleaned with the gas dissolution water, physical force can be used concurrently. For example, a cavitation jet sprays the gas dissolving water to the substrate as cavitation jet fluid. The nozzle for cavitation jet fluid is provided with a high-pressure water-feeding pipe 1 and a low-pressure water-feeding pipe 2, and the gas dissolving water is sent to both water-feeding pipes.  At a nozzle output, high-pressure water is jetted out of an opening 3 with a small area at the center of the nozzle, and low-pressure water is jetted out of an opening 4 with a large area in a concentric shape which surrounds the periphery.

IPC: G01P15/11
Filed: 1988-06-08
Abstract: PURPOSE:To generate an output signal quickly when a fixed deceleration occurs while enabling continuation of the output signal for a long time by operating a plurality of magnetosensitive elements sequentially with a magnet performing a pendulous motion to make output signals thereof overlap one upon another. CONSTITUTION:A magnet 5 is mounted at the lower end of an arm 3 within a case 2 and a switch body 7 composed of lead switches 7a-7c is provided on the opposite side of a stator 6 as magnetosensitive element. Then, when the magnet 5 makes a pendulous motion centered on a rotary shaft 4, the switches 7a-7c are operated sequentially from the closest thereof to the magnet 5 to output a signal. When the magnet 5 moves to an adjacent switch operation area from an operation area of one switch, at least two switches both come into operation to output signals being overlapped. In this manner, this deceleration sensor outputs signals continuously until the operation of the last switch 7c from the start of a first switch 7a. This allows the prolonging of time sufficiently for the outputting of signals with the deceleration sensor thereby outputting signals stably.

Abstract: PURPOSE: To ensure an easy transmission for the white signal of the flat-bed scanning facsimile by providing the pseudo white area less than one main scan length to the beam optical path for scanning and thus extracting only the signals of the pseudo white area.  
     CONSTITUTION: Laser beam 18 generated from laser tube 17 performs scanning among beams 20∼22 via scanning mirror 19. Then the flat-bed scanning is given to transmission original 24 laid flat onto transmission original table 23, and the gradation information of original 24 is converted into the electric signals via linear sensor 25 using the PIN photo diode. While secondary scan feed mechanism 26 shifts table 23 toward arror 28 for the secondary scanning. Mirror 19 is driven as shown by arrow 27 to give the reciprocal motion to beam 21. Accordingly, if table 23 is set so that beam 18 may cross pseudo white 32 for scanning at the transmission time of the white signals, V signal underwent the photoelectric conversion for time T which is decided by the pseudo white setting position and length is generated. The position and the length for generation of signal V is decided by the setting position and length of the pseudo white plus one main scanning time.

Title: Two component developing agent and color developing process using the same
Inventor: KISHI HIROYOSHI
IPC: G03G15/01
Filed: 1987-06-05
Abstract: PURPOSE:To obtain a developing agent freed of turbidity of color, uniform magnetic characteristic in its carrier particles, and having higher function by regulating the particle size of the carrier particles to a sufficiently small value by using magnetic iron oxide particles derived from magnetotactic bacteria for the magnetic carrier particles. CONSTITUTION:Magnetic iron oxide particles derived from magnetotactic bacteria are used for magnetic carrier particles of a two component developing agent. Since the bacteria contain plural (10 - several tens) magnetic bodies in the cell, the magnetic bodies are used as magnetic particles by separating the magnetic bodies consisting of iron oxide. The magnetic bodies have extremely fine and uniform particle size as well as high purity. Accordingly, magnetic characteristics of a developing agent are made uniform due to high purity and uniform particle size and uniform quality of magnetic particles when magnetic particles derived from magnetotactic bacteria are used for the magnetic carrier particles, moreover, the turbidity of color caused by the magnetic carrier particles is eliminated.
