Abstract: PROBLEM TO BE SOLVED: To stably support a panel even if its oblique direction differes by providing an annular collar plate on a support member provided turn-elevateably on a base table, and forming a plurality of panel support projections protruding upward at equal spaces on the upper face of the collar plate. SOLUTION: A support member 4 having threads formed on a periphery is turn-elevateably attached to the upper face of a base table 1 having a flat bottom 2. The support member 4 is unitedly provided with an annular collar plate 5 extending in a direction vertical to its elevating direction, and a plurality of panel support projections 6 protruding upward is formed at equal spaces in a circumferential direction on the upper face of the collar plaate 5.

Title: Control system of pulse motor
Inventor: KAWACHI MUNEYOSHI
IPC: H02P8/40
Filed: 1984-03-29
Abstract: PURPOSE:To perform smooth starting, acceleration, deceleration and stop of motors and to synchronously operate motors by connecting one or more sets of control circuits with common reference pulse generator, and externally controlling the switching circuit in the control circuit and a gate circuit. CONSTITUTION:When a signal is simultaneously applied to terminals 7, 8 to rotate a pulse motor 2, a gate circuit 4 and a switch 6 are operated to apply a voltage of high level generated at a phase comparator 8 to an analog filter 5, a voltage rising gradually by the time constant is output to the output side, applied through a diode 10 to a voltage control type oscillator 3 to increase the oscillating frequency, thereby increasing the rotating speed of the motor 2. The motor 2 rotates by the repetition frequency in a pulse generator A. When the signal of the terminal 7 is interrupted, the rotating speed of the motor 2 is gradually decreased to the rotating speed decided by a constant-voltage generator 12. Then, when the signal of the terminal 8 is interrupted, the motor 2 is stopped.

Title: Image-forming apparatus
Inventor: TAKEHARA ATSUSHI
IPC: B41J2/455
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To enable colorful gradational expression without requiring a complicate control in an electrophotographic process using an LED array. SOLUTION: In the case of light emission by LED elements alone, adjacent two LED elements are let to emit light so slightly as not to exceed a reaction limit value of a photosensitive body (a threshold value whereby toners adhere to an exposed part of the photosensitive body after charged uniformly), and exposures on a surface of the photosensitive body by the faint emission lights are overlapped. An electrostatic latent image 13a (denoted as a pseudo latent image for the sake of convenience) of nearly the same diameter as that of an electrostatic latent image (denoted as a normal latent image for the sake of convenience) formed on the surface of the photosensitive body consequent to normal light emission by one LED element is formed at a middle part. Since an apparent recording density is increased, colorful gradational expression is obtained without requiring a complicate control.

Title: Growing method of single crystal
Inventor: KURATA YASUSHI
IPC: C30B29/34
Filed: 1994-03-30
Abstract: PURPOSE:To obtain a single crystal without producing cracks. CONSTITUTION:A cylindrical zirconia refractory material as the refractory material around a crucible is preliminarily divided into two parts and assembled in such a manner that the one space is a little larger than the other space. The crucible is heated by high frequency induction heating to melt the source material, and temp. of the molten liquid is properly controlled for deposition on the seed. Thus, the convection flow is changed to flow to the crucible wall where the larger space between the refractory materials is made. Thereby, Ir floating in the flowing position of the convection moves to the wall of the crucible and deposits on the crucible wall. Then, the lower end of the seed crystal is brought into contact with the molten liquid and the seed is pulled up to develope into the crystal. Thereby, crack is prevented in a single crystal which easily causes cracks.

Title: Original image reader
Inventor: SUGIURA HIROKO
IPC: H04N1/107
Filed: 1995-02-23
Abstract: PURPOSE: To prevent the slippage, simplify the structure, and reduce the cost by pressing an original placed on an original table by a sheet-shaped intermediate original pressing cover having openings formed therethrough to position it, and then covering the upper part with a cover. CONSTITUTION: An intermediate original pressing cover 3 is rotated in the closing direction to press an original 1 placed on an original table 2 by a pressing surface 3a. Since opening parts 4 are provided in the thickness direction of the cover 3, air by the wind pressure at pressing is passed from each opening part 4 in a direction B. Thus, the original 1 is positioned in a position for reading an original image, and prevented from being slipped. The original 1 is finally pressed by rotating the cover 3, and a cover 5 is successively closed, thereby, the original image is read by a reading part. Thus, the opening and closing wind pressure of the covers 3, 5 are never imparted to the original 1 placed on the original table 2, and the original 1 is positioned in the position for reading the original image, and prevented from being slipped.

Title: Television system converter
IPC: H04N7/01
Filed: 1992-03-17
Abstract: PURPOSE:To avoid the effect of deviation in a horizontal synchronization of an input video signal onto a pattern and to avoid improper operation of write and read to/from a memory. CONSTITUTION:Two memories 23A, 23B are operated alternately in the write/ read state to convert the number of lines and the number of fields. Horizontal synchronization on the read side is synchronized with the horizontal synchronization on the write side in the vicinity of the vertical synchronization location on the read side in the system conversion and the non-system conversion. A picture frame of a video signal written in the memories 23A, 23B is changed in response to a deviation in the horizontal synchronization of the input video signal and the deviation in the horizontal synchronization on the write side in the system conversion. Since the effect of the deviation in the horizontal synchronization of the input video signal is propagated to the read side during the vertical blanking period of the read side, no skew appears on an output pattern. Furthermore, since the picture frame is changed according to the deviation, the overlapping of the write/read operation of the memories 23A, 23B is prevented.

Title: Voltage level conversion circuit
Inventor: HIRANO HIROSHIGE
IPC: H03K19/0185
Filed: 1995-03-20
Abstract: PURPOSE:To confirm an output signal even when the voltage of an input signal is low or the voltage between the input signal and a voltage source of the voltage level conversion circuit is high in the voltage level conversion circuit. CONSTITUTION:A P-channel MOS transistor(TR) (early cut-off circuit) Qp1603 is connected between the source of a P-channel MOS TR Qp1602 and the voltage source VPP of a voltage level conversion circuit. An input signal I16 is given to the gate of the P-channel MOS TR Qp1603. When the input signal I16 has the voltage of the voltage source VCC, since the node N1601 is set to a potential (VCC-Vtn), the P-channel MOS TR Qp1603 is more turned off than the off state of the P-channel MOS TR Qp1602, and then the voltage level of an output signal O16 is confirmed quickly to an L level.

Abstract: PURPOSE:To efficiently detect the beam light even in the case of a body to be examined in which a difference of a refractive index is large against air such as a living body, etc., and to easily obtain a satisfactory tomographic image which scarcely causes a false image by placing at least two light transfer means consisting of a member whose refractive index is roughly equal to that of the body to be examined, between a light scanning means and a detecting means. CONSTITUTION:From a semiconductor laser, a near infrared ray is generated like a beam, scanned within an irradiation range 3 by a scanner 4, and made incident on a first light transfer part 7. A first light transfer part 7 is made of a material whose refractive index is equal to that of a buffer liquid 10 having good light permeability, and this incident side face has a curvature by which beam light is always made incident vertically. The emitting side face is equal to the curvature of a shell 8 so as to adhere closely to the shell 8 of a light transfer part 6, therefore, the light is led to a second light transfer part 6 without a refraction of light. This light transmits through the shell the buffer liquid 10 an elastic film 9 a body 5 to be examined the elastic film 9 the buffer liquid 10 the shell 8, and is led to a detector 11 through a third light transfer part 12.
