Title: Image forming device
Inventor: HANEDA SATORU
IPC: H04N1/04
Filed: 1991-11-06
Abstract: PURPOSE:To easily constitute a potential adjustment exposure means and to facilitate the limitation of an exposure range by allowing the potential adjustment exposure means to use an image exposure device and a scanning optical system in common. CONSTITUTION:A potential adjusting/irradiating means is composed of the potential adjustment beam projecting means 4 and the scanning optical system 5 used for the image exposure device. The potential adjustment beam projecting means 4 is composed of a semiconductive laser 41 and a beam diameter adjusting means 42. As the semiconductive laser 41 of the potential adjustment beam projecting means 4, one which is the same as the semiconductive laser 31 of an image beam projecting means 3 is preferably used because the one which outputs laser beam with a wavelength which is less absorbed by the toner of a previously formed toner image is preferable and because a laser array in which the semiconductive lasers 31 and 41 are integrally arranged can be employed. Also, because the one which is the same as the beam diameter adjusting means 32 can be driven and controlled therewith in parallel and the one in which they are arranged integrally can be used, it is preferably used.

Title: Magnetic recording/reproducing device
Inventor: HONGO KIMITOSHI
IPC: G11B5/09
Filed: 1989-11-06
Abstract: PURPOSE:To record the information through one of two channels and at the same time to reproduce the recorded information through the other channel by scanning (2XN) tracks or more in a single cycle period of information to record theinformation at one of both sides and at the same time to reproduce the information at the other side. CONSTITUTION:A pair of magnetic heads 2a and 2b having a 180 deg. space between them are attached to a rotary drum 1. Then the drum 1 is revolved at a sped double as high as conventional speed and at the same time a magnetic tape 4 is fed at a speed double as high as conventional speed. Thus the track of the type 4 revolves twice within a conventional signal revolution of the drum 1. That is, a 1st magnetic head 2a scans a track 15 with the first revolution together with a track 16 scanned by a 2nd magnetic head 2b. In the second revolution, the tracks 17 and 18 are scanned by the heads 2a and 2b respectively. In these four tracks, the tracks 15 and 17 are defined as one of two channels with the tracks 16 and 18 defined as the other channel respectively. Thus one of both channel is recorded and at the same time the other channel is reproduced.

IPC: G02F1/1337
Filed: 1988-11-15
Abstract: PURPOSE:To prevent a macrodomain which depends upon the step height from an adjacent area and a rubbing direction from being formed by decreasing parts of both flanks of a gate bus line and a data bus line and end surface of respective thin film transistor parts which abut on a rubbing-directional back surface stepwise in thickness. CONSTITUTION:Parts of both flanks of various bus lines GB and DB and end surfaces of respective transistor parts which abut on the rubbing-directional back surface 31 are decreased stepwise in thickness, its lower stage 42 and upper stage 41 are formed stepwise or the lower stage 42 is tapered, and the step height of the lower stage 42 from the adjacent area is reduced so that no macrodomain is formed. Therefore, the maximum thickness of the various bus lines GB and DB and respective transistor parts can be set nearly to conventional thickness. Consequently, the enough thickness for the resistance reduction of the bus line DB is secured and the macrodomain is prevented from being formed.

Title: Chip-on-glass substrate
Inventor: SHIROKURA HIDEAKI
IPC: H05K3/34
Filed: 1989-11-07
Abstract: PURPOSE:To uniform the bump height and bump diameter at the time of solidifying the solder by forming an acute-angle part at the connection part between a lead-out electrode and an electric conductor pattern. CONSTITUTION:Electric conductor patterns 5 which have acute-angle parts 4 are formed at connection parts between lead-out electrodes 3 extended radially from pads 2 and the lead-out electrodes 3. Then a chip component 6 coated with flux is positioned on this substrate and then the flux flows on the substrate; when the flux reaches the acute-angle part 4 at the connection part between the lead-out electrode 3 and electric conductor pattern 5, the flux is stopped from flowing by receiving resistance at the acute-angle part 4. Then a solder bump is heated and fused and the fused solder comes to constant in flow solder amount among respective bumps. Consequently, the chip-on-glass substrate which are constant in the bump height and bump diameter among the respective bumps at the time of solidifying the solder is obtained.

IPC: H02P25/08
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a motor, by shortening the leading and trailing times of a current flowing through the excitation coil of a stator. SOLUTION: In a driving device for exciting coils C1 to C3 around the salient poles of a stator sequentially, an output signal from a rotating angle sensor 4 is fed to a frequency divider 7A of an arithmetic circuit 7 and converted into a driving signal for each transistor Q1 to Q6 connected on both sides of the coils C1 to C3. Transistors Q1 to Q6 are switched by the driving signal. The make and break of the current flowing through the coils C1 to C3 is controlled to change the coils C1 to C3 in an excited state. When the exciting coils C1 to C3 are changed, a current carried at the former exciting coil is turned to the following exciting coil, and thereby the leading and trailing of current is made abrupt.

Title: Spiral gasket
Inventor: YAMASHITA SEIICHI
IPC: F16J15/12
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a spiral gasket not causing a buckling on the inner circumferential side when fastening even without an inner ring. SOLUTION: In this gasket, a support hoop 6 having support projection parts 6a locally projecting outward in the radial direction is joined to the outer circumference of a gasket body 3. Because a gap corresponding to projecting size of the support projection parts 6a is formed between the outer circumference of the gasket body 3 and the inner circumference of an outer ring 2, radial outward-moving deformation on the outer circumferential side of the gasket body 3 is allowed to reduce inward-moving deformation on the inner circumferential side when fastening the gasket body 3. Thereby, no buckling can occur even without an inner ring. By using a strip-like metal chip plate similar to a hoop 4 constituting the gasket body 3 as the support hoop 6, a total production cost becomes lower.

Title: Output buffer circuit
Inventor: ICHIMURA TORU
IPC: H03K19/0185
Filed: 1986-12-05
Abstract: PURPOSE:To reduce a time till the change of an output data signal started from the change in a sense amplifier output signal by providing a level setting circuit using an output pulse from an ATD circuit so as to bring the level of an output data signal to a level between 'H' and 'L' to an output buffer circuit. CONSTITUTION:No output data signal f1 is outputted with an output from an output control circuit 13 at the state of 'L', and a pulse (c) being the result of retarding an output pulse (b) generated from the ATD circuit 11 detecting the change in an address signal (a) inputted to a semiconductor storage device in the state of 'H' is inputted to gates of MOS transistors 8, 9 and 10. Then the level of a NAND output signal d1 and a NOR output signal e1 goes to a level between the 'H' and 'L' and the level of the output data signal f1 goes to a level between the 'H' and 'L'. When an output of a sense amplifier 12 changes from 'L' to 'H' (or from 'H' to 'L') at a time t2, the signal f1 changes from the level between 'H' and 'L' to 'H' (or 'L'), resulting that the data is outputted faster by a time of (t4-t3) than a conventional circuit.
