Title: Developing apparatus of electrophotographic copier
Inventor: EBI YUTAKA
IPC: G03G15/09
Filed: 1978-03-25
Abstract: PURPOSE: To enhance carrying performance of developing means, by catching and carrying a magnetic toner standing still between magnets on both sides, each pole of one side facing to the pole of opposite polarity of the other side and both moving in the same direction and at the same speed.  
     CONSTITUTION: When toner carrying belt 4 starts moving in the arrow direction, magnets 41 on belt 4 attract a toner near the outer wall of vessel 3, and move it in the direction of developing sleeve 2. On the other hand, magnet roller 21 also starts rotating in the arrow direction, and these magnet poles 22 attract the toner carried with carrying belt 41 toward sleeve 2. In addition, both magnetic pole 22 and 41 face to each other in such a manner that one side pole faces to the other side pole of reverse polarity, and both move in the same direction at the same speed, moving the toner caught by both the poles at the same speed. Therefore, when both the poles get apart from each other after that, the toner once caught by the magnets of sleeve 2 is firmly attached to sleeve 2 and sent to the surface of photosensitive drum 1.

Title: Thin-film forming method
Inventor: HASEGAWA TOSHIAKI
IPC: C23C16/52
Filed: 1994-03-04
Abstract: PURPOSE:To prevent an abnormal growth by introducing silane gas into a CVD device where a load lock chamber is connected to the front stage of a reaction oven and then forming a ground film with a small substrate surface dependency at the initial stage of film formation when forming a desired thin film on a substrate in the reaction oven. CONSTITUTION:When forming a film by an LPCVD device, the inside of a load rock chamber 2 is evacuated and the inside of the reaction oven 1 is heated to a desired temperature by a heater 6 and at the same time air is exhausted by an exhaust port 7, thus reducing pressure to a desired value. Then, a wafer port 4 is moved by a transport mechanism, a wafer 3 is carried from the load lock chamber 2 to the reaction oven 1, and then a feed gas is introduced from a gas supply pipe 5, and then SIN thin film is formed in the wafer 3. In this case, after SION thin film is formed as a ground film on the S1 substrate, the SiN thin film is formed, thus suppressing an abnormal growth and improving film quality.

Abstract: PURPOSE:To make it possible to obtain an electronic and/or optical element utilizing a phenomenon that electrons or positive holes turn to be Bose particles, by a method wherein a track drawn when a multiply connected structure is moved in parallel in the direction intersecting the characteristic plane perpendicularly is made to be an active region. CONSTITUTION:Two-dimensional electron gas 2DEG 101 shaped in a hollow cylinder has a doubly connected structure obtained when a ring of the doubly connected structure is moved in parallel in the direction intersecting the characteristic plane thereof perpendicularly. Now, when it is assumed that a magnetic flux PHI pierces this 2DEG 101 shaped in the hollow cylinder, a change in the magnetic flux PHI brings about a change in the angular momentum of electrons constituting this 2DEG 101, and the electrons are turned to be Bose particles by the impression of a magnetic field. Thereby an electronic and/or optical element utilizing a phenomenon that the electrons or positive holes turn to be the Bose particles can be obtained.

Title: Rear projection type display system
Inventor: OGINO MASANORI
IPC: G03B21/62
Filed: 1995-02-23
Abstract: PURPOSE: To enlarge the horizontal divergence angle of a rear projection type display to >=50 deg. in right and left directions and also to improve a contrast ratio. CONSTITUTION: The light exit part of a lenticular sheet 5 is formed into one body through a transparent reinforcing plate means 11 and a bonding means 12. The refractive index of the material is selected so as to be nearly equal to each other. Thus, the vignetting of light having a divergence angle of >=50 deg. in respective right and left directions and which is generated in a conventional technology is avoided based on Snell's law. Since the horizontal divergence angle is enlarged by >=50 deg. in respective right and left directions and also the duty factor of a black stripe 7 can be enhanced to >=60%, the contrast ratio is improved.

Filed: 1991-02-05
Abstract: PURPOSE:To make variation of noise level between units small by installing a noise detecting circuit and by adjusting stereo separation in accordance with a noise level to lower. CONSTITUTION:To the ATC terminal of multiplexor MPX4, a signal level signal is inputted to control the volume in a high sound range. Further, to the ASC terminal of MPX4, a capacitor C and the collector of transistor TR are connected. The HPF8 filters the noise component of output from a wave detecting circuit DET3, and the noise component is converted to a corresponding voltage by a noise level detecting circuit LDT9, and is impressed to the base of transistor TR. Then, the impedance of transistor TR changes, and a voltage corresponding to the noise level is impressed to the ASC terminal of MPX4. Further, when noise becomes null, stereo separation is recovered. This stereo separation recovering rate is adjusted by a time constant of LDT9, and by carrying out appropriate adjustment between units, the variation of noise level is made small.

Abstract: PURPOSE:To stably hold a temperature sensor with a zigzag fixing member even when an ice-making tray main body is twisted. CONSTITUTION:An ice-making tray main body 21 is twisted as it is turned upside down during ice releasing. A temperature sensor which detects the temperature of the ice making tray main body 21 is arranged in a trough between ice-making blocks 23 and covered with a heat-insulating cover 24 from below. There is a pair of stoppers 23a and 23b on the bottom of the ice-making tray main body 21, and both ends 25a and 25b of a zigzag-shaped fixing member 25 are inserted into the stoppers 23a and 23b from inside to attach the temperature sensor. A protrusion 26 is formed on the heat-insulating cover 24 and time fixed end of the zigzag-shaped fixing member 25 is held between the protrusion 26 and the stopper 23b. Therefore, even when the zigzag-shaped fixing member 25 is deformed with twisting of the ice-making tray 21, the protrusion 26 prevents the zigzag-shaped fixing member 25 from coming off the stopper 23b.

Filed: 1983-03-07
Abstract: PURPOSE:To prevent the decrease of the operating margin of a memory cell due to working dispersion by a method wherein the capacitor of the memory cell is composed by connecting two capacitors of approximately the same structure as the capacitor of a dummy cell in parallel. CONSTITUTION:In the memory cell 7, of an active region 16, regions 17A and 17B having a gate oxide film under a plate 5 form a memory cell capacitor. This cell 7 has the region forming the region 17 divided into the two regions 17A and 17B. The plate 5 has the mutual connection of each one electrode of the two capacitors formed respectively on the regions 17A and 17B, which electrode thus becomes the electrode common to the two capacitors. The regions 17A and 17B and a region 24 which forms the capacitor of the dummy cell 6 are of the same structure and the same dimensins. Therefore, even when working dispersion occurs, the regions 24, 17A, and 17B scatter in the same manner, accordingly it becomes possible to secure the capacitance ratio of the capaciance of the cell 10 to that of the cell 7 at 1:2.
