Title: Method and apparatus for optical inspection
Inventor: UCHIKAWA KIYOSHI
IPC: G01N21/64
Filed: 1994-07-04
Abstract: PURPOSE:To obtain an optical inspection apparatus in which the echo of accumulated light can be detected accurately from fluorescence even under a state where the intensity of exciting laser light fluctuates. CONSTITUTION:Light from a light source 100 passes through an optical system 200 for optical modulation to produce linearly polarized orthogonal components. The optical path length is varied sequentially by an optical delay unit 230 for one component whereas the phase is modulated by a phase modulator 220 for the other component before both components are combined to irradiate a sample M. Fluorescence emitted from the sample M is split by a polarization beam splitter into linearly polarized orthogonal components and the intensity thereof is measured with detectors 341, 342 and then the difference is determined by a differential amplifier 343. A lock-in amplifier 344 amplifies only the component having frequency two times that of the modulation frequency for the difference data. Finally, a phase releasing time is determined based on a relationship between the results thus obtained and the delay time.

Title: Image display method
Inventor: SATO MASATAKE
IPC: G09F19/12
Filed: 1990-06-11
Abstract: PURPOSE:To see through an image without recognizing the image by obtaining an opaque sheet equipped with a seeing-through function using holes as seeing- through elements and an opaque dot image equipped with a seeing-through function using holes as seeing-through elements. CONSTITUTION:The opaque sheet 1 can display the image 2 and can be bored for the seeing-through elements 3, and the image 2 neither oozes nor is embossed on the reverse surface of the opaque sheet 1. The sheet is made of an opaque material or sheet in an opaque state which can erase the oozing and embossing to prevent the trouble of the image, and seeing-through elements 3 are fine. For example, when this is stuck on the rear windshield of a vehicle with the image out, the driver can see through an outside scene through the rear windshield without recognizing the image, and the drivers of following vehicles can recognize the image clearly. Consequently, when the outside scene on the image display side is seen through from the reverse side of the image display, the outside scene can be seen through without recognizing the image.

IPC: H04L29/06
Filed: 1990-06-08
Abstract: PURPOSE:To reduce the processing time of a work station side by compressing a data for each packet at a network and sending plural packets to a server for one packet transmission period. CONSTITUTION:When a work station gives request to a compression flag ON 101 to a network, the network sends a packet 102 with a compression flag at its head and compresses a data 103 sent from the work station for each packet and sends the data to the server by plural packets. The server discriminates the compression packet according to the head flag packet, expands the received data and outputs the result to the printer. Thus, the data transfer speed is increased by 3 - 4 times in a conventional system and the processing time of the work station is reduced.

Title: Mechanical type parking facility
Inventor: NISHIURA MORINOBU
IPC: E04H6/06
Filed: 1995-06-20
Abstract: PURPOSE: To attain compactness by setting a distance between post centers at both ends from the car drive-in side shorter than a distance obtained by multiplying the array pitches of pallets at the normal places of storage by the number of the pallets. CONSTITUTION: Since a distance A between the post centers 2a of posts 2 at both ends of a framework body 4 is set at a value shorter than a distance acquired by multiplying the pallet array pitches B of lifting-lowering pallets P1 and traversing pallets P2 by the number of the pallets arrayed by DX2, the distance A is shorter than a conventional distance. When parking facilities 1 are juxtaposed, the framework bodies 4 are juxtaposed so as to be continued at regular pitches so that the pitches B between the adjacent facilities 1 are continued between both facilities 1. Since the distance A is shorter than the overall length of the pitches B, the adjacent posts 2 of both framework bodies 4 do not interfere mutually at slight distances.  Accordingly, the framework bodies can be compacted while an installation space can be contracted, and the facilities 1 can be juxtaposed without rearranging the framework bodies and increasing the number of parts.

Title: Information processing device with function of power supply saving
Inventor: SAKAI TATSUYA
IPC: G06F1/26
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To perform control of power supply saving including a frontlight of an information processing device provided with a reflection type liquid crystal display device. SOLUTION: As for a reflection type liquid crystal display device 15, display contents can be read without turning on a frontlight 14 when surrounding is sufficiently bright. Whether the frontlight 14 is turned on or not is controlled by a switching state of on/off of an input switch 21 or surrounding brightness sensed by an optical sensor 27. When a user does not operate an input device 12 for a fixed time, a switch circuit 18 is turned off and the device enters into a power management state in which the frontlight 14 is turned off. When a user operate the input device 12, the switch circuit 18 is turned on and a resume processing is performed. Since the frontlight 14 is not turned on in a situation in which it is not necessary to turn on, effective power consumption saving is realized.

Inventor: ONIMURA KUNIHARU
IPC: G05B11/42
Filed: 1981-09-28
Abstract: PURPOSE:To realize accurate control by executing PID control while carrying out zero-cross switching. CONSTITUTION:A zero-crossing detection part 7 inputs a signal Es and outputs a signal E1. A temperature detection part 11 outputs a signal E2 corresponding to the temperature of a heater 1. A subtraction part 15 subtracts a signal E3 outputted from a temperature setting part 16 from a signal E2 and the differencial signal E4 is inputted to an operation part 17. When signal E4<0, the operation part 17 executes PID operation and outputs a signal E5 and, when E4>=0, outputs a ''0'' signal. A signal generation part 24 outputs a symmetrical square wave signal E6 (period T0). When signal E4>=0, an integrator 18 decides its output so that a feedback signal E7 is ''0''. Therefore a voltage control part 3 applies no voltage Eh to a heater 1. When signal E4<0, the voltage control part 3 turns on the voltage Eh in accordance with the operation of the integrator 18, a Zener diode 25, a comparator 26, and an NAND circuit 27.

Abstract: PURPOSE:To prevent a signal value from being changed by attaching another digital circuit on an analog processor device, and holding an output signal without drifting for a long time when a fault is generated in the operation of the processor. CONSTITUTION:When the operation of a microprocessor 1 is performed normally, a digital signal following the output signal Vout of a signal holding circuit 2 at every constant cycle is held at a counter 4 by a loop consisting of a counter 4, a D/A converter 5, a comparator 6, and a logic circuit 7. When abnormality is generated in the operation of the processor 1 at such state, the fact is detected by a monitoring means 3, and a switch SW1 is operated, then, the processor 1 is separated. In other words, a gate control circuit 73 in the circuit 7 receives a signal from the means 3, and cancels the above loop, and simultaneously, turns on the switch SW1 until malfunction in a synchronous circuit 74 is eliminated. Next, when the fault is eliminated, the digital signal without having the fault just before held at the counter 4 is inputted to the signal holding circuit 2 via the converter 5, and the output signal Vout is sent out from the circuit.
