Title: Parallel priority deciding circuit
Inventor: KAWASHIMA TAKAAKI
IPC: G06F12/00
Filed: 1990-02-28
Abstract: PURPOSE:To attain the system integration accordant with the action/function conditions of a system by setting freely the deciding conditions of the parallel priority and the timer conditions from outside. CONSTITUTION:The arbitration is carried out by a priority deciding means 5 for conflict of the request signals BREQ based on the fixed priority deciding conditions, i.e., the priority deciding conditions designated from outside, the variable priority deciding conditions, and the rotary priority conditions respectively. Then the means 5 produces an enabling signal to a signal BREQ 1. A timer means inhibits forcibly the signal BREQ when this signal is kept active for an externally designated time or longer after the enabling signal is sent. Thus the reference priority for decision of the parallel priority can be externally and internally and automatically changed. Thus it is possible to prevent such a fault if occurs to keep the signals BREQ active from affecting an entire system.

Abstract: PURPOSE:To achieve an audio signal with possible excellent sound quality, by detecting the state of an interference signal through the change in the tuning frequency for a prescribed frequency width taking a desired reception frequency as the center and setting the constitution of an amplifying circuit to a most suited state. CONSTITUTION:A control signal Vc is outputted to change the tuning frequency upper and lower by taking a frequency f0 as the center by DELTAf from a channel selection circuit 9. From a narrow band amplifying circuit 6, an intermediate frequency signal corresponding to the signal level at a point apart by DELTAf is outputted, the level is detected via a level detection circuit 7 and a signal E(DELTAf) is obtained. A signal corresponding to DELTAf is outputted from the circuit 9 and applied to an RF constitution amplifying circuit 10. The circuit 10 compares a signal corresponding to the DELTAf and the signal E(DELTAf) with the stored data, and the optimum constitution of the circuit 10 is obtained to the state of the interference signal, and a set signal VX corresponding to the constitution is applied to an RF amplifying circuit 2. As a result, the tuning characteristics or gain of the circuit 2 can be set to the most suited content in matching with the reception state at that time.

Abstract: PURPOSE:To make use of the advantages of 2 wavelength 1 beam system and make possible the use of thermistors, etc. which are more inexpensive than condenser microphones as a pressure detector by parallel disposing the specific two gas cells sealed therein with gases of different kinds. CONSTITUTION:Infrared rays go through a window 19, a detecting cell 12 where gas such as butane is flowable and further through windows 24, 23 and enter the first gas cell 20 which has approximately the same optical length and has been sealed therein with butane and the second gas cell 21 which has been sealed with HCN having the absorption wavelength extremely close to the infrared ray absorption wavelength of butane. When there is butane in the bath 12, a difference in the pressure increase owing to the temperature rise having absorbed infrared rays in the cells 20, 21, occurs, hence the displacement quantities of membranes 27, 28 differ, producing the gas current of N2 sealed in the adjoining small gas cells 25, 26. As s result, the pressure detecting element 30 having been heated in a pressure detecting chamber 29 is cooled and the change in its resistance drives an alarm circuit 33 through an amplifier circuit 31 and threshold value discriminating switch circuit 32.

Abstract: PROBLEM TO BE SOLVED: To efficiently perform charging processing to printing processing on a network. SOLUTION: A client 102 transmits a printing request file and a slip file 104 to a charging server 100. The charging server 100 transmits a printing permission file 110 describing the permitted amount of resources such as the number of usable print paper sheets to the client 102. Based on the resource amount, the charging server 100 prepares charging information and stores it in a charging information file 108. Preceding to the slip file, the client 102 transmits the printing permission file 110 to a printer device 112. Only when the printing permission file 110 is transmitted before the slip file 104, the printer device 112 executes printing processing. The charging information can be managed while being centralized and the control of printing can be efficiently performed.

Abstract: PURPOSE:To obtain an excellent reproduced picture without disturbance by applying frame processing to a field reproduction signal with a delay circuit for 1/2 horizontal period and using a 90 deg. phase shifter so as to switch the phase of a chrominance subcarrier signal for each field. CONSTITUTION:A color video signal reproduced from one field only constituting one frame is switched for one field each (switch 16) by using a delay signal (circuit 15) for 1/2 horizontal period to apply frame processing. The phase of a subcarrier signal in a color signal component in a color video signal is switched for one field by using 90 deg. phase shifters 11, 12 (switch 13). Thus, the phase of the chrominance subcarrier signal is shifted by 90 deg. for each field and the consecutive phase of the chrominance subcarrier signal after frame processing is obtained and an excellent reproduced picture without disturbance is attained.

Title: Vehicle detecting method
Inventor: ODA GORO
IPC: G01V1/00
Filed: 1995-03-09
Abstract: PURPOSE: To exactly detect the existence of a vehicle when the phenomenon of multiple-time detection is generated by judging the existence of vehicle in the case where the peak voltage value of a reflected wave detected within an arrival time zone after the transmission of ultrasonic waves exceeds the peak voltage value of a stored floor surface reflected wave. CONSTITUTION: The ultrasonic wave from an ultrasonic sensor S is reflected on the surface of floor and detected in the state where no entering object exists within the range of detection. The peak voltage value of the reflected wave detected by this ultrasonic sensor S is previously stored and the peak voltage value of the reflected wave detected in the arrival time zone previously applied as the time for the floor surface reflected wave to be detected is monitored. Then, the detected peak voltage value of reflected wave is compared with the stored peak voltage value and when the detected peak voltage value of reflected wave exceeds the stored peak voltage value, the existence of vehicle is judged. Thus, the presence/absence of vehicle inside the detection range can be detected.
