Title: Electrophotographic sensitive body
Inventor: ICHISAWA NOBUYUKI
IPC: G03G5/06
Filed: 1990-09-17
Abstract: PURPOSE:To obtain the electrophotographic sensitive body good in electric chargeability, rapid in potential decay due to incidence of long wavelength light, and high in sensitivity by combining a charge generating layer containing a dithiopyrrolopyrrole compound with a charge transfer layer containing a phenyldiamine compound specified in structure. CONSTITUTION:The charge generating layer contains at least one of the dithioketopyrrolopyrrole compounds represented by general formula I and the charge transfer layer contains at least one of the compounds represented by general formula II. The binder resin of the charge transfer layer to be used is such as polycarbonate, polyester, polymethacrylate, polyacrylate, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl acetate, and styrene- butadiene copolymer. It is preferred to mix a charge transfer material with the binder resin in a ratio of 5:1 - 1:5, and if >5:1, mechanical strength is lowered, and if <1:5, sensitivity is deteriorated.

Title: Ultra-low-carbon crystal growing apparatus and production of silicon single crystal
Inventor: SUZUKI RINTAROU
IPC: H01L21/208
Filed: 1992-09-14
Abstract: PURPOSE:To obtain a silicon single crystal with reduced carbon content by growing a crystal from its melt while heating a crucible by a heater and bringing a carbon-contg. gas generated from a thermal insulating material to outlets to prevent the gas from being allowed to flow into a growing chamber. CONSTITUTION:A crucible 2 and a heater 3 are placed in a crystal growing chamber 1 and a thermal insulating material 4 consisting of inorganic fibers are provided around the chamber; the resulting assembly is put into a refractory member 5. Gas outlets 10 are provided at both lower ends of the wall of the chamber 1, and a carbon-contg. gas generated from the thermal insulating material 4 is forcedly brought, via a gas passage 15, to the outlets 10 to prevent the gas from being allowed to flow into the chamber 1. And, owing to a trimmed flow of an Ar gas stream through a purge tube 16 toward the melt surface, the CO2 and SiO produced can quickly be discharged. With this system, the crucible 2 is charged with a Si polycrystal material which is then heated and melted. A seed crystal is then immersed in the melt 6 and continuously pulled up while rotating, thus obtaining the objective Si single crystal 7 with reduced carbon content.

An axial component is applied across a shank 4 and the body 2 relatively rotating with each other via the spring rollers 1 so that the fluctuation of the rotary load torque is changed in the axial displacement of the body 2 at high efficiency. A mandrel connected to the head of the body 2 is axially moved.

Abstract: PURPOSE:To decrease inductance, by forming the thickness of a gate electrode pad so that its thickness is sufficiently thicker than a source electrode pad, and making it possible to connect bonding wires to substrate circuit wirings in the state of a straight line. CONSTITUTION:On a GaAs field effect transistor 1, a gate electrode pad 2 and a drain electrode pad 3 are formed on the upper surface of the transistor. A source electrode pad 4 is further formed so as to surround the gate electrode pad 2.

Title: Master/slave screen signal synthesizing circuit for-highvision receiver
Inventor: INOUE NAOYUKI
IPC: H04N5/45
Filed: 1992-08-20
Abstract: PURPOSE:To synthesize a slave screen obtained by one of HD and NTSC signals to a part of a master screen obtained by the other signal with no display distortion like the horizontal expansion or contraction, etc., occurring on a screen. CONSTITUTION:A 1st NTSC signal and a 1st HD signal are digitized and led to a slave screen switching circuit 34, and one of both signals is selected as a slave screen signal. Thus a slave screen processing circuit 38 processes a slave screen of a prescribed size. A 2nd NTSC signal is digitized and then converted into an analog signal after the time base of the signal is compressed by a 1st time base converter 30. This analog signal and a 2nd HD signal are led to a master screen switching circuit 36, and one of both signals is selected as a master screen signal. The slave screen signal undergone the slave screen processing is converted into an analog signal after its time base is compressed by a 2nd time base converter 40. This analog signal and the master screen signal are led to a master screen signal switching circuit 44, switched in the prescribed timing, and outputted to a high-vision monitor. Thus a slave screen is synthesized to a part of a master screen and displayed.

Abstract: PROBLEM TO BE SOLVED: To effectively utilize exchange resources by selectively using a base station and its peripheral base station whose position is registered by using position information of a PHS terminal equipment and adjacent radio base station information so as to retrieve an incoming call use base station. SOLUTION: A portable terminal equipment 300 gives its position information to an exchange 100 via a radio base station 200 in the case of position registration, a position registration means 101 generates position registration information by making the identification information of the terminal equipment 300 and the base station 200 in cross reference with each other to register its position.  In the case of arrival of call to the terminal equipment 300, an incoming call radio base station selection means 104 selects the incoming call radio base station based on position registration information and adjacent radio base station storage information, the portable terminal call reception means 102 reaches the call to the selected base station and relays the base station receiving a call from the terminal equipment among the selected base station to reach a call to the terminal equipment 300. Thus, the base stations used actually for the call reception to the terminal equipment are narrowered and the use of all base stations contained in the exchange is not required to utilize effectively the exchange resource.

Abstract: PROBLEM TO BE SOLVED: To give appropriate force to a liquid suction pipe regardless of the kinds of target container, that is, a closed or open container by moving a first holding part up and down for a container without any plug without engaging it to a second holding part by a control means and moving the first holding part up and down for the container with a plug while engaging it to the second holding part by a second drive source. SOLUTION: When a pipette 12 is to be lowered, a control part 92 monitors a signal from an outer force detection circuit 55. When the contorl part 92 detects that outer force is applied to the pipette 12, it judges that a container is a closed one, stops a first motor. Otherwise, the contorl part 92 judges that the container is an open one. In the case of the closed container, a drive source 72 is driven, a washing part 60 is lowered, and a cap 69 of a container 68 is pressed and held. A motor 43 is stopped and a second motor 86 is rotated. A second holding part 74 presses down a first holding part 30 and sticks the pipette 12 into the cap 69. In the case of the open container, the motors 43 and 86 are rotated and the holding part 30 is lowered without touching the holding part 74.

Title: Unequal orientation recording medium
Inventor: NAKAMATSU YOSHIRO
IPC: G11B5/845
Filed: 1990-09-18
Abstract: PURPOSE:To provide the head output constant from the inner periphery to outer periphery of a magnetic disk by orienting a magnetic material perpendicular to the disk surface on the inner periphery of the magnetic disk, gradually decreasing the perpendicularity toward the outer periphery and decreasing the orientation to zero on the outermost periphery. CONSTITUTION:The magnetic material on the inner periphery of the magnetic disk 1 is oriented most perpendicular to the disk surface as shown by orientation 3 and the perpendicularity is gradually decreased toward the outer periphery. The orientation is decreased to zero as shown by the orientation 4 on the outer most periphery. Namely, the orientation of the magnetic material is irregular on the outer side, is sufficient on the innermost peripheral side and is weak in the intermediate part. The decrease in the output by a decrease in the linear speed on the inner periphery is compensated by a difference in the orientation in this way, by which the outputs between the inner and outer peripheries are equaled. Since the output on the inner periphery can be increased. The formation of the magnetic layer on the inner periphery to a smaller thickness is possible and the degradation in the resolving power on the inner periphery is thereby prevented.
