Patent JP-S638920-A (JP)
Title: Optical coordinate input device
Inventor: OUCHI JUNICHI
IPC: G06F3/03
Filed: 1986-06-30
Abstract: PURPOSE:To obtain a proper coordinate signal even in the presence of a faulty light emitting element and to perform normal operation by detecting whether or not a driving current flows to a light emitting element and inhibiting corresponding count data from being stored in a storage device unless the driving current flows owing to a fault. CONSTITUTION:Currents flowing to light emitting elements L1-Ln which are selected by a switching circuit 1 and driven and scanned are detected by detecting means PT1-PTn and when the currents flow to the light emitting elements L1-Ln, count data is inhibited from being stored in the storage part 7. Therefore, if the light emitting elements L1-Ln output no light signal owing to a fault, count data corresponding to the faulty light emitting element is ignored and only count data indicating proper coordinates is stored in the storage part 7. Consequently, even if the faulty light emitting element is present, the device is able to operate normally.

Title: Container with discharge port
Inventor: ARAI ISATO
IPC: B65D47/28
Filed: 1995-06-20
Abstract: PURPOSE: To slide a lid with resistance so that the lid may not be accidentally opened/closed in a container with a discharge port for receiving particular candies or the like by forming a locking part with a width reduced from an end position to a sliding part when a leg of the lid slides in a guide hole. CONSTITUTION: This container 13 with a discharge port has its leg 11 of a lid 10 fitted into a guide hole 4 of a container body 1, wherein to open the discharge port 3, the lid 10 is slid to have it moved from a locking part 5a at an end position to a locking part 5b at a start position, and since a width from the locking part 5a to a sliding part 6 is reduced, certain force is required for moving the lid 10. In addition, since long holes 8 are formed at both ends of the sliding part 6, when the leg 11 slides in the sliding part 6, a shelf 9 between the long hole 8 and the guide hole 4 is pushed toward the long hole 8. Thus the leg 11 can be slid with relative small force though some resistance exists with restoring force of the shelf 9 received.

Title: Data reception system and communication controller
Inventor: YOKOYAMA TATSUYA
IPC: H04L12/40
Filed: 1992-06-15
Abstract: PURPOSE:To reduce a reception processing time at the reception of a frame by starting protocol processing and transfer of received data to a computer in response to a coincidence signal between a predicted header and a received header from a comparator circuit. CONSTITUTION:Plural prediction headers of a frame expected for succeeding reception are registered to a communication controller 2 and data received from a network 3 are fetched in real time. Then a comparator circuit 100beta compares the plural fetched prediction headers with the received data simultaneously to discriminate whether or not the received data are registered in the prediction headers. Protocol processing and the transfer of the received data to a computer 1 are started in response to a coincidence signal between the prediction header and the received header outputted from the comparator circuit 100beta. Thus, three ways of processing such as frame reception from the network 3, protocol processing and transfer processing of the received data to the computer 1 are overlapped respectively to reduce the entire reception processing time of the controller 2.

Title: Axial gap type motor and polygon mirror scanner motor
Inventor: HAYASHI KUNIO
IPC: G02B26/10
Filed: 1993-06-25
Abstract: PURPOSE:To allow low torque high speed rotation by subjecting a magnetic focusing yoke constructed integrally with a rotor assembly to the magnetic attraction of a rotor magnet. CONSTITUTION:A magnetic focusing yoke 34 is attracted magnetically to a rotor magnet 32 but since they are secured to a rotary shaft 27 through a flange 30 and a spacer 33, respectively, the distance is kept constant at all times. Consequently, magnetic attraction of the rotor magnet 32 can be offset within a rotor assembly by subjecting the magnetic focusing yoke 34 constantly to the attraction of the rotor magnet 32. Since only the self-weight of the compositional part of rotor assemble, e.g. the rotary shaft 27, is imposed as thrust load to a sliding thrust receiving part 26, low torque high speed rotation is realized.

Filed: 1988-06-24
Abstract: PURPOSE:To improve the efficiency in use of an apparatus by supplying DC power of a pulse width corresponding to the load change of each switching circuit from said each switching circuit corresponding to a load. CONSTITUTION:In two switching regulators, unstabilized common DC power is supplied to the primary winding of transformer T1, T2 via switching circuits SW1, S#2. Said circuits SW1, SW2 are ON-OFF controlled on the basis of the deviation of their output voltage from a specified voltage so that said output voltage is controlled to a constant output voltage. In this case, pulse-width control signals S13, S23 are separately generated on the basis of the deviation of switching regulator output voltage from the specified voltage and inputted into pulse-width modulation circuits K1, K2 to bring said switching circuits SW1, SW2 to ON state alternately and aperiodically. Thus, even if DC current always flows out from the common DC power supply, its change is limited as much as possible.
