Title: Light-emitting diode
Inventor: OSAWA KAZUHIRO
IPC: H01L33/30
Filed: 1987-09-28
Abstract: PURPOSE:To enhance the coupling power of a fiber by a method wherein the central part of a light-emitting face is structured to be a circular protruding form or a ring- shaped protruding form and a resin of an appropriate amount is coated on the circular protruding part or the ring-shaped protruding part and on a recessed part surrounded by the ring-shaped protruding part in order to form a lens. CONSTITUTION:An AlGaAs-based doublehetero type surface light-emitting diode where an active layer 4 is sandwiched between AlGaAs clad layers 3, 5 is formed to be a thick-film structure where a GaAs substrate has been removed completely. A band gap of the thick-film AlGaAs clad layer 3 is larger than that of the active layer 4; the GaAs substrate is removed so that light emitted from the active layer 4 cannot be absorbed by the GaAs substrate; the light can be extracted to the outside from the side of the thick-film n-type AlGaAs clad layer 3. A circular protruding part (a) is formed in the central part of a light-emitting face on the surface of the AlGaAs clad layer 3 by using an etching operation; a silicon-based resin of an appropriate amount is coated on the surface of the protruding part (a) in order to form a lens 1. An n-side electrode 2 is formed around the protruding part; a P-side electrode 6 is formed on a whole face of the p-type AlGaAs clad layer 5.

Title: Flotation carrier device and flotation carrier system
Inventor: TSUJIMURA MASAYUKI
IPC: B65G51/03
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To move even a heavy platelike substrate at high speed by pushing and moving a floating platelike substrate. SOLUTION: When a glass plate 300 is carried to a transferring part 1 at the time of a state in which a female screw part 13G reaches the motor side, a driving device 13B lowers a bed plate 13C. As a result, a holding part 13H2 moves downward and holds a glass plate 300. Subsequently, the motor rotates and the female screw part 13G moves. As a result, the holding part 13H2 moves in the same direction as the female screw part 13G and the glass plate 300 moves in a floating state. When the glass plate 300 reaches the supporting part side, the driving device 13B pushes up the bed plate 13C. At this time, the glass plate 300 moves to the next transferring part 1 and a control unit by inertia because the glass plate 300 is in the floating state and friction does not exist between the glass plate 300 and a carrier surface 11A.

Title: Growth preventing method of weeds on boundary of structure
Inventor: TOTSUGI MASAICHI
IPC: E01H11/00
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a means capable of preventing weeds from growing relatively simply and semipermanentty on the boundary part of structures.

Title: Communication terminal device
Inventor: SAITO TERU
IPC: G06F21/62
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent the abuse such as the illegal copy (clone) of the inherent information of user stored in a nonvolatile memory. SOLUTION: An eigenvalue setting means consists of a variable resistor 125 and an A/D converter 126. The moving element position of the resistor 125 is moved and adjusted at random, and the converter 126 outputs a random eigenvalue VP for every telephone set. A nonvoltile memory 117 stores the inherent information of a user and also the above-mentioned eigenvalue VP as an inherent key, e.g. when produced. For instance, when the power is on, a normal operation continues as a telephone set only when the eigenvalue VP outputted from the converter 126 coincides with the inherent key stored in the memory 117. When the contents of the nonvolatile memory of another telephone set are copied into the memory 117, the normal operation does not continue but the operation is stopped. Thus, the abuse such as the illegal copy of the inherent information of the user is prevented.

Title: Level variable circuit
Inventor: OKUYAMA KEIICHI
IPC: H03K5/02
Filed: 1988-09-30
Abstract: PURPOSE:To prevent fluctuation of a threshold value by providing an offset voltage superimposing current source FET whose gate and whose source via a variable resistor connects to a collector output at one side of a differential transistor(TR) and whose drain is biased to a positive voltage. CONSTITUTION:A current source 3 is connected to a common emitter of differential TRs 1, 2 and complementary voltage pulses IN, IN' are applied to bases of the differential TRs 1, 2. Thus, the differential TRs 1, 2 is subject to switching operation. Then a current change in the offset voltage superimposing current source FET 8 is superimposed on an output load of the differential TR 2 to vary the DC level of the output level by varying the resistance of a variable resistor 7 in the operating test of the circuit. Even if the mark rate of a pulse signal is changed, the DC level is easily varied around the threshold value of an output pulse by adding the offset voltage superimposing current source FET in this way.

IPC: G03G15/00
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent toner from scattering or penetrating in a toner image transfer. SOLUTION: When assuming the height of a transfer nip T on the upper most side as A, the height of the upper most point 8a of a prior transfer guide 8 as B, and the height of a resist nip R of rollers pair as C, respective value of these is set so that the following relations are valid among these A, B and C, A<B, and B>=C.

Filed: 1993-09-07
Abstract: PURPOSE:To allow a torque converter to be reversed and set always positively into a normal position without requiring to change clamping claws and the like even when the size of the torque converter is changed. CONSTITUTION:The tips of arms 105 laterally extended from a rotating block 101 are provided with sliders 123 linearly movable along a line passing the center of a first assembling table T1 by guide rails 121, and clamping claws 129 are fixed to the sliders 123. The sliders 123 are driven by an air cylinder 111 through a sliding block 115, links 116 and levers 109 so as to grip a set of parts P on the assembling table T1. The rotating block 101 is then reversed around a reversing shaft 103 and transferred onto a second assembling table. Since the clamping claws grip a set of parts always on the line passing the center regardless of the size of the parts set, dislocation caused by the diameter difference of the parts set is not generated. The slider can be additionally provided with a supporting part for supporting the parts of the parts set from the lower side.

Filed: 1989-09-25
Abstract: PURPOSE:To decrease a data storage time for packet-processing a line data of the same destination and same speed and to decrease conversion delay by handling plural lines communicating with a same opposite party equipment as a single line and applying multiplex and packet-processing to the data. CONSTITUTION:A time division multiplex data/packet conversion section 10 is provided with a 1st channel number rewrite section 3, which rewrites each channel number of a channel having the same destination and same speed read by a 1st data storage means 1 into the same channel number.
