IPC: G01N21/27
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To measure accurately the degree of oxygen saturation by performing the heterodyne detection of organism transmission light and eliminating scattered light. SOLUTION: Luminous flux from a laser-generating device 101 is made incident on a first optical fiber 103 from a micro lens 102. The incidence laser beam is propagated through a third optical fiber 111 by first directional coupling equipment 104 and is modulated by a device 112 for varying reference luminous flux phase. By propagating luminous flux that is made incident through a space speckle correction plate 106 from a first directional optical system 105 on an organism sample 107 and is passed through the speckle correction plate 106 with light that goes straight on out of scattered light by a second optical fiber 109 for interfering with a third optical fiber 111, the luminous flux is superposed by second directional coupling equipment 110.  A device 112 for varying reference luminous flux phase consists of, for example, a piezo, and reference luminous flux that is modulated by it and is superposed by a photo detector 113 and signal luminous flux are subjected to heterodyne detection. The luminous flux is demodulated by an amplifier 114 and a demodulator 115.

Title: Copying control method
Inventor: KARASAWA KAZUNORI
IPC: G03G15/00
Filed: 1989-11-07
Abstract: PURPOSE:To preclude a decrease in image density beforehand and a fault by displaying the abnormality of a device unless detection outputs before and after a two-component developer is supplied to a bobbin for toner concn detection are within a specific range, and stopping copying operation. CONSTITUTION:The abnormality of the device is displayed and the copying operation is stopped unless the detection outputs before and/or after the two- component developer 23 is supplied to the bobbin 21 which detects toner concn from the inductance of the two-component developer 23 by supplying the two- component developer 23. Consequently, the misrecognition of the toner concn due to the clogging of the bobbin constituting an F(flow) sensor is judged and if the F sensor becomes abnormality, the copying operation is stopped and that is displayed, so other subsystems are prevented from being faulty owing to a decrease in image density and toner scattering.

Title: Multiplexer/demultiplexer
Inventor: KAWAKAMI NOBORU
IPC: G02B6/293
Filed: 1988-11-15
Abstract: PURPOSE:To obtain sufficient multiplexing and demultiplexing characteristics and to minimize the thinning of a fusion coupling part by fusing and coupling dispersion shift fibers and setting their coupling part length to 7-8mm. CONSTITUTION:The dispersion shift fibers 1 and 1 are coupled with each other and their coupling length is set to 7-8mm. The dispersion shift fibers 1 and 1 which constitute the multiplexer/demultiplexer have fiber parameters such as specific refractive indexes so set that the waveguide dispersion and material dispersion are canceled almost at 1.4-1.6mum wavelength and wavelength dispersion is zero. When the coupling length of this multiplexer/demultiplexer is <=7mm, sufficient optical coupling is not performed. When the coupling length exceeds 8mm, the fibers are drawn more than required and the bending loss of the coupling part 2 increases unnecessarily. Consequently, the multiplexer/ demultiplexer which has small bending loss and high isolation is obtained.

Title: First-in first-out memory device with different size of input output data and its method
Inventor: KIN OKIHIRO
IPC: G06F5/14
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an output of data with a different size from that of input data by using a pointer so as to conduct write/read to/from an FIFO when the size of the input data for write and the size of data to be read differ from each other. SOLUTION: An input section 100 receives data DI corresponding to a mode control signal MOD and provides an output of a data string DBI. A generating section 400 generates a write pointer and a read pointer corresponding to the signal MOD and a buffer 200 is made up of a register block. When the size of data read and outputted is larger than the size of written input data, a write pointer with an incremental width set in advance and a read pointer with a larger incremental width than that of the write pointer are generated. In this case, the incremental width of the read pointer is larger than the incremental width of the write pointer by a ratio of the size of the input data to the size of the output data.

IPC: H04L12/56
Filed: 1994-11-24
Abstract: PURPOSE: To effectively execute an isochronous connection processing by providing a buffer occupation time reduction mechanism for controlling the flow of data, which passes through the exchange node of a system, avoiding congestion in the node and reducing necessary buffer storage. CONSTITUTION: An exchange node 12 partially exists in an exchange controller 24 and it monitors the operation states of isochronous connection, which are established through the exchange port of the node. The single exchange 22 of a cross bar switch designates the route of data to a related transmission exchange port from the reception exchange port of specified connection. When it can be delivered, a port control mechanism 34 gives a command so that the stored packet is taken out from a buffer 32 through an input control mechanism 30 for transferring it to the exchange 22. Then, the exchange 22 transfers the packet to the output control mechanism 36 to a transmission exchange port 20.  An unillustrated source exchange node delays the delivery time of the subsequent isochronous packet by the reduction mechanism of buffer occupation time corresponding to a feedback signal by using a feedback message.
