Title: Grinding head of centerless grinder
Inventor: DAITOU MICHIMASA
IPC: B24B41/04
Filed: 1978-09-04
Abstract: PURPOSE: To dress the sides of a girnding stone and always provide precision grinding while keeping its position unchanged before and after the dressing, by shifting the position of the stone in the axial direction by the amount of dressing.  
     CONSTITUTION: When a work is infeed-ground during the simultaneous grinding of its flange, a grinding stone 6 becomes dull due to loading as the grinding continues. For dressing the stone 6, a handle 15 is operated to axially shift a housing 10 of thrust bearing by means of a feed screw rod 16. Then a spindle 2 held by the housing 10 and a st tic pressure journal bearing are shifted in the axial direction to dress the stone by a radially traversed dresser 20.

Title: Operation spring structure of electromagnet device
Inventor: OGURA TAKASHI
IPC: H01F7/16
Filed: 1989-04-25
Abstract: PURPOSE:To change the load acting on a plunger without changing the spring constant of the operating spring of an electromagnet device by moving a pressing piece forward or backward in the direction of the plunger by means of an adjusting means so as to adjust the pressing force to the plunger. CONSTITUTION:An operating spring 9 is provided in such a way that the main body 13 of the spring 9 is fixed to a coil frame 11 and a plunger 12 is pressed by means of a pressing piece 15 while the locking section 20 of a leg piece 16 is hooked on hooking pieces 18. In case the load acting on the plunger 12 is changed, the locking section 20 is hooked on other hooking pieces 17 and 19. When the leg piece 16 is hooked on the piece 17, a rising piece tilts forward and the force of the pressing piece 16 pushing the plunger 12 increases and the load applied to the plunger 12 increases. When the piece 16 is hooked on the piece 19, the rising piece 14 tilts backward and the load acting on the plunger 12 decreases.

Title: System for compressing picture signal band
Inventor: ASHIBE MINORU
IPC: E05B13/10
Filed: 1987-04-30
Abstract: PURPOSE:To prevent the visual deterioration in picture quality owing to the difference of the quality caused by the difference of a mode by calculating interpolating error from a picture signal, making it as original interpolating error, correcting a part of the original interpolating error or the whole interpolating error with the aid of past original interpolating error or a past mode, making the result of the correction as corrected interpolating error and deciding the mode with the aid of the corrected interpolating error. CONSTITUTION:When the picture signal is inputted, the original interpolating error S for the mode 2 of each block is calculated. Then, a some fixed value alpha is added to the original interpolating picture element of the block which is the mode 1 at one before field and made the corrected interpolating error S' for each block. A histogram about the corrected interpolating error is produced and the content of it is read from it's bigger corrected interpolating error and added to the value alpha. Then, the value of the corrected interpolating error S' when more than one-third of the whole blocks are read is made to be a threshold value (Th). The whole blocks are assigned to the mode 2 or the mode 1 according as it's corrected interpolating error S' is over or below the threshold value (Th) and outputted. Thus the variation of the mode being the cause of deterioration in the image quality can be controlled.

Abstract: PURPOSE:To prevent a nozzle from being clogged, by arranging a resilient member between a cap abutting against an ink jet head and a case therefor so that the cap is forced against the head by the resilient force to improve the close contact therebetween. CONSTITUTION:The resilient member (a coil spring in the embodiment shown in the Figure) 9 is arranged between the cap 6 that abuts against the forward end 1B of the ink jet head 1 and the case (holder) 4 for the cap 6, so that the cap 6 is forced against the forward end 1B of the head 1 by the resilient force. Thus, the close contact between the cap 6 and the forward end 1B is improved, and therefore clogging with ink at a nozzle forward end 3A can be prevented. If clogging with ink at the forward end 3A of the nozzle 3 has occurred, the clogging can be easily solved by applying suction to a passage 6A that is in communication with the cap 6.

Title: Driving circuit
Inventor: KAWAI RIYUUICHIROU
IPC: H03F1/02
Filed: 1991-04-12
Abstract: PURPOSE:To improve the driving capability by providing a circuit controlling a current flowing to the input electrode of a couple of transistors(TRs) constituting a push-pull circuit so as to compensate the current flowing to an output electrode. CONSTITUTION:When a signal fed to an input terminal IN rises, the base voltages of TRs Q1, Q2 rise. Thus, the base potential of a TR Q9 is going to rise. When a load is heavy in this case, the base current of the TR Q9 is increased. Thus, the emitter current of the TR Q1 is decreased and the collector current of the TR Q1 is decreased. However, since the current I flowing to a constant current source 4 is constant, when the collector current of the TR Q1 is decreased, the emitter current of a TR Q6 is increased. Thus, the collector current of the TR Q6 is increased and the collector current of a TR Q7 is increased. The collector current of the TR Q3 is increased by a current mirror and the base current of a TR Q9 and the emitter current of the TR Q1 are increased.

Title: Non-volatile semiconductor storage
Inventor: TANAKA SUMIO
IPC: G11C16/02
Filed: 1989-04-27
Abstract: PURPOSE:To improve the reliability of a cell and to sense data at high speed by directly inputting the data of a selected cell through a column selecting transistor to the input end of a sense amplifier and setting the threshold value voltage of this input end to a low value so as to detect the potential of a column line. CONSTITUTION:Since the column line is clamped lower than the power supply potential for reading by a transistor for column line potential clamp when the data are read, the reliability of the cell can be improved. The data of the selected cell are directly inputted through column selecting transistors CSa and CSb to the input end of the sense amplifier and the threshold value voltage for the input end of this sense amplifier is set the low value so as to detect the potential of the column line. Accordingly, data sense operation can be execut ed without using a double step sense system. Thus, when the data sense opera tion is executed, a transfer gate is not included in a route to discharge the charges of column lines BLa, BLb, BL''a and BL''b in a low level side and internal delay from the column lines BLa, BLb, BL''a and BL''b to the sense amplifier is reduced. Then, an access time is improved.
