Patent JP-H04336583-A (JP)
Title: Cleaning method for latent image carrier
Inventor: MATSUMOTO KENTARO
IPC: G03G21/10
Filed: 1991-05-13
Abstract: PURPOSE:To prevent the deterioration of image quality due to the deposition and coagulation of abrasives by forming a toner deposition pattern containing the abrasives on the surface of a photosensitive body, and removing the pattern with a cleaning blade, while reducing the rotation speed of the photosensitive body. CONSTITUTION:While a toner deposition pattern is formed on the surface of a photosensitive body 1 after image formation, and being removed with the edge section 8a of a cleaning blade 8, the surface of the photosensitive body 1 is cleaned with abrasives contained in the pattern, thereby removing a contamination substance such as ozone generated due to corona discharge. In this case, the photosensitive body 1 is caused to rotate at normal speed for image formation until the toner deposition pattern is completed, including image formation. Also, when the pattern reaches a cleaning device 7 and is cleaned, the rotation of the photosensitive body 1 is delayed. According to this construction, toner and abrasives agitate each other in the vicinity of the edge section 8a, and the deposition and coagulation of the abrasives on the edge section 8a can thereby be prevented.

Title: Ultrasonic-pulse type distance measuring apparatus
Inventor: MORI HIDEO
IPC: G01B17/00

Abstract: PURPOSE:To output the freezing rates of the vibrating surface of an ultrasonic wave piezoelectric transducer at a plurality of stages based on the width of a pulse by providing a means for converting the freezing rate of the vibrating surface of the ultrasonic wave piezoelectric transducer into the pulse width. CONSTITUTION:Wave sending pulses from a distance measuring part 6 of a control part are sent into a ultrasonic wave piezoelectric transducer 1 for sending ultrasonic wave pulses and set out toward a body. The reflected wave from the body is received with the ultrasonic wave piezoelectric transducer 1. The output of the received wave is inputted into a detecting part 5, and the received wave form is shaped. Then, the wave is inputted into a distance measuring part 6. The time required for transmitting and receiving the wave is measured. The distance to the body is measured based on the measured time. The wave sending pulse which is sent into the wave sending part 2 from the distance measuring part 6 is also inputted into a freezing detecting part 3. The freezing rate of the vibrating surface of the ultrasonic wave piezoelectric transducer 1 is converted into the pulse width in the freezing detecting part 3. The freezing rates of the vibrating surface are outputted from an output part in a plurality of stages based on the pulse widths outputted from the freezing detecting part 3.

Title: Printer
Inventor: OKUBO HIROSHI
IPC: B41J29/38
Filed: 1992-05-29
Abstract: PURPOSE:To utilize the data of the accurate total time of printing operation for maintenance work such as the replacement of an abraded part by storing and controlling the data to print the same. CONSTITUTION:A receiving interface 1 receives data from a host and a printing control means 41 analyzes the data to control a printing mechanism 3 to perform printing. The printing control means 41 issues a command for a timer means 42 to measure a printing operation time during printing and a non-volatile read/write memory means 43 adds the printing operation time measured by the timer means 42 and the total time of printing operation prior to this to store the added value. When the switch push down data of an operation switch panel 2 coincides with the predetermined combination of push-down switches when a power supply is closed, the printing control means 41 obtains the data of the total time of printing operation from the non-volatile read/write memory means 43 and controls the printing mechanisms 3 to print the total time of printing operation.

Abstract: PURPOSE:To obtain a good image on a recording material by providing a water- repellent resin layer to the peripheral faces of a pair of squeeze rollers. CONSTITUTION:The squeeze roller pair 176 consists of an elastic material such as rubber. The water-repellent resin layer 177 consisting of polytetra- fluoroethylene, etc., is provided on the peripheral faces thereof. Excess water is, therefore, run down on the squeeze roller 176 and is recovered into a water tank 174 when the squeeze roller pair 176 pinches and transports a photosensi tive material A and scrapes the excess water. Since the surfaces of the squeeze roller pair 176 have water repellency, sticking of the contaminants contained in the water and the image forming material, etc., on the photosensitive material A onto the surfaces of the squeeze roller pair 176 is obtained and the contamina tion of the surface of the squeeze roller 176 is obviated. The good image record ing on the recording material is thus executed.

Title: Production of plastic bristle product
Inventor: GEORUKU BUAIRAOHO
IPC: A46D3/04
Filed: 1988-06-06
Abstract: Brushwear can be manufactured by melting the bristle bearer and, if appropriate, the ends of the bristles and joining them together under pressure or by inserting the bristles into an injection or foam mould for the bristle bearer and embedding them in the bristle bearer material by injection or foaming. Due to the thermal processes (heating, melting, injecting, cooling), the cycle time for these processes is very long. It can be reduced considerably by moving the tools for holding or manufacturing the bristle bearer on the one hand and clamping devices for the bristles on the other hand on closed-loop paths, transferring the clamping devices to at least one common station on the path of the tools, moving them along with the tools at least during the thermal processes and then returning them to their path of movement.

IPC: B41J2/175
Filed: 1992-05-29
Abstract: PURPOSE:To reduce the fluctuations of the ink pressure in the ink emitting nozzles of an ink jet recording head and enhance the utilization efficiency of ink. CONSTITUTION:In such a state that an ink tank T is used in an ink jet recording apparatus, the ink joint 21a provided to the lower end part of the ink tank T communicates with the ink emitting nozzles of a head chip 18. The ink held by the porous ink holder 25 received in the ink tank T receives atmospheric pressure from above to be supplied to the head chip 18. Since the inside volume of the ink tank T becomes large from below to above, the change of the ink pressure (negative pressure) in the head chip 18 accompanied by the consumption of ink can be reduced when the initial residual amount of ink is relatively much. Since ink is gathered to the region having a small cross section of the lower part of the ink tank T when the residual amount of ink is little, the final residual amount of ink can be reduced.
