Title: Facsimile equipment and facsimile communication method
Inventor: KOBAYASHI MAKOTO
IPC: H04N1/32
Filed: 1993-12-06
Abstract: PURPOSE:To improve the operability of a facsimile equipment in regard of its communication procedure by storing the communication information and its registration data of a receiver on the transmitter side and detecting coincidence of stored registration data between the transmitter and receiver sides for execution of the communication control. CONSTITUTION:In a transmission state where the transmitter side performs the calling by means of the one-easy-step or abbreviated dialing, a CPU 3 refers to an abbreviated procedure operation flag included in a RAM 5 and sends the register date to the receiver side by means of a non-standard function setting signal (NSS) and via a MODEM 2 and a network controller 1. At the receiver side, the registering/updating dates set at its own equipment and received by the signal NSS after a circuit is caught is compared with the date registered in its own equipment. When the coincidence is confirmed between both dates, an acknowledge signal is transmitted. Then a receiving processing is carried out based on the reception pointing instruction produced at the transmitter side. Thus it is possible to previously know at the transmitter side that the communication information on each receiver is changed and also to effectively use the communication time.

Title: Damper for door closer with temperature compensating mechanism
Inventor: KAMEDA KAZUNORI
IPC: E05F3/14
Filed: 1994-11-15
Abstract: PURPOSE: To improve the function, by changing the sliding area of a rotor and a movable body to freely adjust the brake force and changing the sliding area of the rotor and the movable body by a bimetal to offset the viscosity change of a viscous fluid. CONSTITUTION: A linear motion or the like of a sliding door is converted to a rotary motion through a mechanism like rack and pinion to rotate a rotor 3 and also the torque is braked by the drag of a viscous fluid 2. In this time, a movable body 5 is shifted by an adjusting screw 4. The sliding contact area of the movable body 5 and the rotor 3 is changed to adjust the braking force. The bimetal 6 is warped greatly in a low temperature for instance. The contact area of the rotor 3 and the movable body 5 is reduced to cope with the change of viscosity of the fluid 2 and make the damping force constant even if a temperature difference has arisen. A one-way clutch is provided in the pinion or the like to block the rotary motion of pinion not to transfer it to the damper on opening the door.  In this way, the brake force can be easily adjusted and the device can cope with the change of environmental temperature and the door also can be opened with a little force.

Title: Automatic setting method for control arithmetic period of digital controller
Inventor: TEJIMA KEIZO
IPC: G05B11/36
Filed: 1986-12-22
Abstract: PURPOSE:To optimize the load to a digital controller by having processes for calculation of the load factor and change of the control arithmetic period. CONSTITUTION:A basic period process 200 is started and executed for each prescribed basic period as a timer interruption process against a normal process which is usually started repetitively and gives the control arithmetic to a device to be controlled. The value A of a control arithmetic period counter is counted up and compared 201 with its set value B. Then it is decided that a new arithmetic control period is started when the value A is larger than the value B. Thus a control arithmetic end flag set in a normal process is checked 204. An error flag ER1 is set at '1' before the control arithmetic is through and the average load factor is calculated in an average load factor calculating process. Then this average load factor is compared with a set load factor and an error flag ER2 is set at '1' when the average load factor is larger than the set load factor. When the flag ER1 or ER2 is kept at '1', '1' is added to the set value of the control arithmetic period counter. Thus the control arithmetic period is changed to the larger value.

Filed: 1987-12-03
Abstract: PURPOSE: To eliminate a flour remaining at the corner parts, and make a bread of a favorable appearance by making a kneading bar advance/retract in/from a kneading container by a plunger. CONSTITUTION: A plunger 39 pushes the flange part 37 of a kneading bar 8, and the kneading bar 8 protrudes in a kneading container 6. By the rotation of a blade 10, materials in the kneading container 6 are stirred, and the materials are gradually kneaded up into a bread dough between the blade 10 and the kneading bar 8.  At this time, one part of the non-kneaded flour sticks to the kneading bar 8 and the corner part opposite from the kneading bar 8, and the plunger 39 is controlled so as to retract after a specified period of time, and the leading end of the kneading bar 8 becomes the same surface with the side wall of the kneading container 6, and for this reason, the bread dough is kneaded by the blade 10 only, and freely moves in the kneading container 6, and by doing so, the bread dough comes into contact with the remaining flour in the corner parts, and draws in the flour, and the remaining flour is gradually eliminated. Then, the kneading bar 8 is projected again, and the dough is well kneaded between the blade 10 and the kneading bar 8, and a favorable dough is finished.

Title: Image forming device and method for forming electrostatic image
Inventor: FURUTA HIDEYA
IPC: G03G15/01
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To prevent image blurring and an abnormal image from occurring caused by a slippage by preventing the slippage from being generated between a photoreceptor and an intermediate transfer body in an image forming device. SOLUTION: When a negative electrostatic latent image is formed by irradiating the electrostatically charged photoreceptor 9 with light from a writing optical unit 8, this part of the photoreceptor 9 is developed as the toner images of respective colors by developing units 14-17. The toner image is imprinted on the intermediate transfer body 19, next. However, since the photoreceptor 9 is electrostatically charged as it is at this time, electric attracting force is generated between the photoreceptor 9 and the transfer body 19. When the attracting force becomes stronger, the slippage is generated between the photoreceptor 9 and the transfer body 19 and the image blurring is caused.  Then, the image blurring is prevented from occurring by discharging the non- image area of the surface of the photoreceptor 9 by using a charge removing device 54 before the photoreceptor 9 is brought into contact with the transfer body 19, eliminating the attracting force and preventing the slippage from being generated.
