Title: Light-transmissive substrate for electrophotographic photoreceptor, manufacture thereof and electrophotographic photoreceptor, image forming method and image forming device using that
Inventor: MOCHIZUKI FUMITAKA
IPC: G03G5/12
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a light-transmissive substrate for an electrophotographic photoreceptor and its producing method having good dimensional stability without optical distortion and excellent image characteristics in which a photoreceptor substrate has high mechanical strength and stability even when it is repeatedly used and to provide the electrophotographic photoreceptor, an image forming method and an image forming device using the substrate. SOLUTION: This light-transmissive substrate of an electrophotographic photoreceptor is formed from a polymer resin and the weight reduction by heating of the light-transmissive substrate is controlled to 0.01 to 5.0%. If the reduction rate of the substrate weight exceeds 5.0% when the substrate is exposed to a high temp. as 100 deg.C till the weight reduction is not observed, the mechanical strength and dimensional stability of the substrate decrease at the time of producing the photoreceptor or when the photoreceptor is used for a long time. Moreover, the potential characteristics and image characteristics of the photoreceptor after stored with time deteriorate.  On the other hand, if the weight reduction is extremely small as <0.01%, the plasticity in the inside of the substrate is extremely small so that the inner distortion can not removed or cracks are easily produced even by an external small impact. Therefore, the reduction rate is preferably controlled to 0.02 to 3.0% and more preferably 0.03 to 1.0%.

Title: Method for inserting watermark to digital image or compressed digital image, digital image capturing device, computer system and method for detecting alteration of digital image with watermark
Inventor: BHASKARAN VASUDEV
IPC: G06T1/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce distortion and to easily verify alteration by partially decoding digital images, generating plural data blocks, judging whether or not to bury watermark bits and burying the watermark bits in the data blocks. SOLUTION: Images are partially decoded, plural blocks are generated and the quantization variable of the conversion coefficient of a highest frequency in the respective blocks is obtained and multiplied with the conversion coefficient. Whether or not to bury the watermark bit is judged based on the coefficient and the remaining watermark bit number of the watermark to be buried, the least significant bit of the conversion coefficient of the highest frequency of the block for which burying is decided is set to zero and a hash value calculated in the last block is turned to the hash value of the entire images. Then, by calculating the watermark from the hash value by using a secret key and digital signature algorithm, a ciphered hash value is obtained and the LSB of the conversion coefficient of the block to perform burying is matched with the watermark bit.

Title: Mask
Inventor: MORI SUSUMU
IPC: G03F1/62
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To accurately transfer a pattern without transfer defects even when a mask having a large-size circuit pattern for exposure is used. SOLUTION: Plural numbers of pellicle frames 13-16 adhered with pellicles 17-20 are arranged on a mask 10 having a circuit pattern so that the pattern is divided by the frames 13-16 based on the pattern arrangement. Thus, even when the mask 10 is made large in size, the frames 13-16 and the pellicles 17-20 can be made small in size according to the arrangement of the circuit pattern. Thus, deformation of the pellicle frames 13-16 and pellicles 17-20 can be prevented and the pattern can be accurately transferred without producing transfer defects.

Title: Constant position stop control system of rotor
Inventor: TOYOSHIMA NARIHISA
IPC: G05D3/00
Filed: 1980-07-02
Abstract: PURPOSE:To increase the reliability of a stop control and to eliminate a backup mechanism, by shifting a rotor to the constant position stop range after once decelerating the rotor down to the zero speed. CONSTITUTION:A position detecting means 4 detects a magnet 3 mounted to a part of a rotor 2 which is driven by a motor 1; and a comparing part 5 which produces the signal to give a forward or backward drive to the motor 1 at both sides of a blind sector of a certain range and to the output signal. Furthermore a speed control means 12 gives a control to the motor 1 to a slow speed, forward low speed and backward low speed each; and a means 6 detects that the speed of the motor is reduced to zero. Thus a slow operation is given to the motor 1 by a stop command after the speed of the motor is reduced to a level near zero. Then a speed control is given to the motor 1 under a forward or backward low speed when a specific point of the rotor 2 reaches a prescribed control range that is decided by the output of the detector 4. And the motor 1 is stopped when the specific point of the rotor 2 reaches the blind sector.

Title: Current limiting type electronic switch device
Inventor: EJIRI KAZUYASU
IPC: G05F1/56
Filed: 1986-04-18
Abstract: PURPOSE:To prevent the normal operating range of a control transistor from being limited, by constituting a device so that a current supplied to a load is monitored, and the current supplied to the load is limited when it increased over a normal current set in advance. CONSTITUTION:Since the fourth transistor Q2 for the detection of a load current is turned to an on-state when a load current I0 exceeds over the normal current, the base current of a control first transistor Q1 is pulled in, and simultaneously, a diode D1 is changed from a cut-off state to the on-state. By turning the diode D1 to the on-state, the base position of the third transistor Q4 is lowered, therefore, the third transistor Q4 is turned to the cut-off state, and the second transistor Q3 is also turned to the cut-off state. Thus, the load current I0 is cut off, and an output power source line, or the voltage V0 of an output signal line goes to zero bolt.

Title: Multiple spindle cooling device
Inventor: INOUE HITOSHI
IPC: B23Q11/12
Filed: 1982-05-26
Abstract: PURPOSE:To provide a variable relation between the diameters of shafts, and cooling and uniformalized quantity of liquid by a method wherein liquid pipes of both main shafts connecting a hollow chamber to a radiater chamber between a bearing and a bearing block through a liquid pipe and a steam pipe are connected together and either the steam or liquid pipe is communicated with another radiater by a flexible pipe. CONSTITUTION:When a bearing block 4 shows a higher increased temperature than that of another block 41, an amount of vapour, steam pressure, and temperature show higher values than those of another block under evaporation of work liquid in a hollow chamber 7 at the block 4, so that a higher evaporating latent heat is taken to provide more cooling and the temperature of the block 4 is prevented from being increased more than that of the other block. Then, the hot steam evaporated in the hollow chamber 7 passes through a steam pipe 10, moves to a radiater 81. The liquid condensed there shows a higher temperature than that of the liquid in the device 8, passes through a liquid pipe 121 and flows into the hollow chamber 71, so that the temperature of the block 41 is increased and a difference in increased temperatures between both bearing blocks is restricted low. Although the amount of liquid in the hollow chamber 71 is increased under repetition of this operation, a part of the liquid is returned back to the hollow chamber 7 through a communication pipe 13 and then unformalized. A span can be made variable in a range of expansion and contraction of flexible pipes 10a, 101a and 13a.
