Title: Transmissive screen and its manufacture
Inventor: SAKUNAGA KENICHI
IPC: G03B21/625
Filed: 1988-11-28
Abstract: PURPOSE:To obtain high precision by mutually fusing light transmissive strands on the outside surfaces of the adjacent individual strands and uniting them integrally in a sheet shape, and constituting a screen body of the single or plural sheets. CONSTITUTION:The outside surfaces 11 of the adjacent light transmissive strands 10 are fused and united integrally, and consequently formed into the sheet shape to constitute the transmissive screen. The transmissive screen is preferably composed of an integrated single sheet, but it may be constituted by connecting two or plural sheets. Even when the plural sheets are connected, pitch precision is increased. The light transmissive strands 10 are thus highly precisely arranged, whereby the screen of excellent performance can be obtained.

Title: Inverter
Inventor: SEKIHARA SOICHI
IPC: H02P6/18
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To utilize the magnetic flux generated from a permanent magnet of rotor of a brushless motor as effectively as possible, reduce a torque variation, and moreover prevent drop of motor efficiency and increase of manufacturing cost. SOLUTION: This inverter is structured to adjust phase of voltage based on the rotating velocity and voltage command in driving a brushless motor 11 in the sine wave driving system. Accordingly, torque variation can be reduced and, moreover, the phase of coil current and phase of induced voltage are not deviated, thereby preventing drop of motor efficiency. In the case of this structure, manufacturing cost does not rise because a current sensor is not required. In addition, since a voltage command can be adjusted when feeding of rectangular wave is changed to the feeding of sine wave, switching can be made smoothly.

Inventor: OSHIMA HIRONOBU
IPC: C10B43/00
Filed: 1989-11-20
Abstract: PURPOSE:To detect the deposition of carbon in high accuracy by calculating a load current as a difference between a forwarding load current in the pushing of coke with a coke-pushing head and the corresponding retreating load current and correcting the calculated value with a load current value based on the weight of coke. CONSTITUTION:Coke produced in a carbonization chamber of a coke oven is pushed with a coke pushing head reciprocating in a prescribed region in the carbonization chamber and discharged to a quenching electric car. In the above process, a pushing load current or load power exclusively under kinetic frictional resistance is calculated as a difference between an average forwarding load current or average forwarding load power from the start of the motion of the compressed coke 2 in the forwarding motion of a coke pushing head 5 through a prescribed range in the carbonization chamber 1 to the start of the discharge of coke into a quenching electric car 7 and the corresponding average retreating load current or average retreating load power. The calculated value is corrected by a load current correction value or load power correction value based on the weight of pushed coke. The deposition of carbon in the carbonization chamber of the coke oven can be detected as the pushing load current characteristic value or load power characteristic value for the determination of the extent of carbon deposition in the carbonization chamber 1.

Title: Optical disk device
Inventor: MORI MASASHI
IPC: G11B7/085
Filed: 1991-10-22
Abstract: PURPOSE:To shorten the track retrieval time by generating a window signal based on a track traverse period to recognize the drop-out of traverse pulses and eliminating unnecessary pulses by a narrow window signal. CONSTITUTION:A computing element 2 calculates the average value of the track traverse period in two past periods measured by a measuring circuit 1 and obtains a next traverse pulse estimate generation time tc. A window generating circuit 6 generates a signal A including the time tc, and a window generating circuit 5 generates a wide signal B including the signal A. Gates 3 and 4 outputs only one first pulse in periods of signals A and B out of pulses generated in a track traverse signal 501. A correction signal generating circuit 8 judges the drop-out of traverse pulses if any pulses are not outputted from the gate 4 before the end of the signal B. A period measuring circuit 1 judges the pulse, which is generated just before a pulse signal B556 generated in a prescribed signal A555 by a measurement timing generating circuit 7, to be a period measurement pulse. A corrected track traverse signal 503 passing a gate 9 is free from pulse miscounting, and the access control of high precision is possible.

Filed: 1994-11-10
Abstract: PURPOSE:To prevent a fault in the transmission of a signal due to the occurrence of a noise and to improve reliability by adding a control circuit with simple constitution so as to attain bus repeating transmission based upon a full duplex system. CONSTITUTION:Since a return signal (d) from a bus side is an 'L' level at the time of starting output from a signal width control part 23, an output signal 12 from an AND gate (AND4) is turned to 'H', so that an output signal (m) from a d-type flip flop (DFF 2) is turned to 'H' and an output (k) is held at 'H' to hold a transmission line from a repeating transmission line side to the bus side. On the other hand, a signal (j) received from the bus side is inputted to the control part 23 and the signal (d) is turned to 'H' level, the signal (k) depends upon the input signal (j) to the control part 23. Since this control is passively executed in accordance with the existence of a transmission signal, the transmission line in this bus repeater can be controlled even when a programmable device is used.

Title: Information channel setting system for isdn terminal
Inventor: KOSHIZUKA EMI
IPC: H04L69/14
Filed: 1990-11-07
Abstract: PURPOSE:To enable an ISDN to set an information channel so as to simplify the process by sending the attribute of the information element 'channel identifier' of a 'call setting' message to an ISDN terminal as 'an arbitrary channel'. CONSTITUTION:A 'call setting' message prepared in advance by means of a control information preparing section 3 is sent from a control information transferring section 2 to the control information section 5 of an ISDN(integrated services digital network). Then 'an arbitrary channel' is set in the information element setting area of the 'channel identifier' of the 'call setting' message. Upon receiving the 'call setting' message, the section 5 analyzes the message and selects a vacant channel by recognizing that the attribute of the 'channel identifier' is 'an arbitrary channel', sets the selected information channel in the 'channel identifier' information element of a 'call setting acceptance' message, and sends the 'call setting acceptance' message to the transferring section 2. Therefore, no channel setting is required the section 2 when the information channel setting function of the ISDN is utilized.
