Title: Cleaning method for electrophotographic photosensitive body
Inventor: SHIRAI MASAHARU
IPC: G03G21/00
Filed: 1988-10-11
Abstract: PURPOSE:To clean well an electrophotographic photosensitive body, which has a smoother photosensitive body surface by setting not only the average roughness of the surface but also the recess and projection cycle, that is the average spacing between the recesses and projections, to a specified range. CONSTITUTION:The average surface roughness Ra of the photosensitive layer is within the range of a formula I, the recess and projection average spacing Sm, is within the range of a formula II, and Ra and Sm fulfill the relationship of a formula III. A doctor blade 2 is abutted on the surface of the photosensitive body 1, and by sliding by a sliding material 3, cleaning of developer 4 is carried out. Thus, when the surface roughness extent of the photosensitive body fulfills the relationships of the formulas I-III, and the cleaning is carried out with the existance of a sliding material, cleaning can be carried out well without generating any vibration in the blade.

Title: Speed detecting device
Inventor: NOMURA MASAKATSU
IPC: G01P3/489
Filed: 1984-11-30
Abstract: PURPOSE:To detect a speed with a good responsiveness and with a high accuracy by providing a speed detecting circuit for deriving a speed detected value of a rotating body from the number of clock pulses in a sampling time, and a compensating circuit for compensating a detection delay by sampling and an operation. CONSTITUTION:In a speed detecting circuit 1, an operation for detecting a speed is executed successively by a sampling timing having a sampling period TS, and speed detected values which are derived, respectively, are detected together with the period TS and a delay of the operation. That is to say, a mean value of the detected value is detected with a delay T from an actual speed. In order to compensate this delay T, an approximation compensating operation is executed by a compensating circuit 2. The circuit 2 stores in advance a speed detected value of one sample before by a sampling circuit 21 and a latching circuit 22, derives a difference of this speed detected value and the speed detected value of this time, by an adder 23, derives a value which has multiplied a variation rate by a compensation time T, by multiplying said difference by a coefficient T/TS, in a multiplier 24, adds the speed detected value of this time to said value by an adder 25, and a compensated speed detected value is obtained.

IPC: B60G17/00
Filed: 1989-09-28
Abstract: PURPOSE:To prevent erronous operation for a combined harvester and thresher and so on, by respectively operating a drive pitching mechanism with a front-to- back directional operation of an operational lever and a drive rolling mechanism with a right-to-left directional operation of the lever so as to tilt a car in each tilting operation direction. CONSTITUTION:By the operation of an operational lever, a manual tilt lever switch 35 is actuated, and switches FDS, BDS, LDS are changed over, so as to actuate a pitching control valve and a rolling control valve, respectively. Namely, in a front-to-back tilt direction of the operational lever, the front down switch FDS and the back down switch BDS are turned ON. In the operation in a right-to-left tilt direction, the left down switch LDS and a right down switch RDS are turned ON. Change-over output of pitching control valve and of rolling control valve is thus carried out respectively, so as to actuate pitching and rolling. Erronous operation can thus be prevented.

Title: Telephone set with message sound recording function
Inventor: AMAMIYA HISATOSHI
IPC: G11B31/00
Filed: 1984-12-04
Abstract: PURPOSE:To enable for using properly by a simple operation, by equipping with a channel transmitting circuit to transmit a regenerative signal to a telephone channel, as well installing means to select the following operating mode and the control means to perform the regenerative output operation corresponding to the selected mode by the conditions of hook switch and setting conditions of the message sound recording mode when a specific operating element that indicates the regeneration is operated. CONSTITUTION:When a button to indicate the message sound recording is pressed, a control circuit 16 is shifted to the sound recording operation by a message sound recording switch SW1. Similarly, when the button to indicate the regeneration is pressed, it enters the regenerative operation by a regenerative switch SW2, and in case a stop button is pressed, it is shifted to the stop opera tion by a stop switch SW3. For this reason, the control circuit 16 shifted to the sound recording operation sets a flag in the message sound recording mode, upon confirming that it is in the conversational state due to the fact that the input from a hook switch HS2 is at the H level. Then, the control circuit 16 records the sound and operates a cassette deck 21 through a deck controller 20.

Title: Manufacture of insulated gate type field-effect transistor
Inventor: NISHIMOTO SHOZO
IPC: H01L21/336
Filed: 1988-10-11
Abstract: PURPOSE:To increase a punch-through withstand voltage by a method wherein, after an impurity is introduced in a substrate using a gate electrode as a mask, an impurity of a conductivity type opposite to that of the substrate is introduced in the substrate surface using sidewalls formed on the side surfaces of the electrode and the electrode as masks. CONSTITUTION:A gate electrode 4 is formed on the surface of a first conductivity type semiconductor substrate (an N-type silicon single crystal substrate) 1 or a first conductivity type well through a gate insulating film 3 and a first conductivity type impurity (P) 5' is introduced in the surface of the substrate 1 using this electrode 4 as a mask to provide insulator sidewalls 6 on the side surfaces of the electrode 4. Moreover, a second conductivity type impurity (B) 7' is introduced in the surface of the substrate 1 using the electrode 4 itself and the sidewalls 6 as masks to form source and drain regions (boron diffused regions) 7. As this result, the junction positions of the regions 7 and the substrate 1 and the impurity concentrations of parts (phosphorus diffused regions) 5 adjoining the regions 7 in the substrate 1 can be set with good controllability without being vexed with the problem of the diffusion coefficient of an impurity. Thereby, a punch-through withstand voltage can be increased.

Title: Ink jet nozzle exciting device
Inventor: KOYAMA AKIHIRO
IPC: B05B3/14
Filed: 1991-09-09
Abstract: PURPOSE:To stably atomize an ink flow jetted out of a nozzle by a method wherein an exciting current for vibrating an electromechanical conversion element mechanically connected to the nozzle varies with an unsymmetrical amplitude. CONSTITUTION:Pressurized ink (including paint) supplied to a nozzle 1 is continuously jetted out of a nozzle hole 2. An electromechanical conversion element 3 mechanically connected to the nozzle 1 vibrates in the axial direction of the nozzle. The element 3 is preferably a stack of a plurality of piezoelectric elements. An exciting power source 6 preferably supplies an alternative current having a symmetrical amplitude to at least one of the piezoelectric elements and an electric current of half-wave rectification waveform to at least one of the other elements. In this manner, as a whole, the element 3 vibrates with an unsymmetrical waveform obtained by synthesizing the two waveforms. Therefore, after being jetted out, an ink flow is powerfully atomized at a small distance from the nozzle hole 2, and the cutting distance is stabilized. In addition, there is no occurrence of satellite. This device especially takes effect with the use of paint.
