Title: Video input device
Inventor: ITO MIKI
IPC: H04N5/232
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To easily update the control information of a camera head part and a universal head part and the signal processing information of a signal processing part and also to perform version management by collectively updating the control information of the camera head part, the universal head part and the signal processing part, confirming matching. SOLUTION: An external device sends information whether each control information to be updated can be matched to control information of pervious version or not to a system controlling part through an external terminal. Here, when all three of a storing part 108 of a camera head part 100, a storing part 204 of a universal ahead part 200 and a storing part 308 of a signal processing part 300 are rewritten, each control information is sent through initial communication of the system controlling part of each part and is separately and sequentially written. However, when only one or two storing parts are updated, a system controlling part 304 checks version collation and sends write notification in the case of being operatable and the notification to that effect in the case of not being operable to the external device.

Title: Ultrasonic wave type doppler flowmeter
Inventor: FUKUNAGA MASAO
IPC: G01P5/00
Filed: 1982-03-12
Abstract: PURPOSE:To make it possible to perform accurate measurement of a flow speed even at a low speed without the effect of the turning flow caused by the bent parts of a pipe and obstacles which disturb the flow, by offsetting the speed component of fluid in the radial direction. CONSTITUTION:A high frequency amplifier part 1 is connected to one common differential high frequency amplifier 15. The signal from a receiving vibrator 3 is inputted to a negative terminal of the differential high frequency amplifier 15, and the signal from a receiving vibrator 5 is inputted to a positive terminal (connection can be reversed). The output of the differential high frequency amplifier 15 is directly inputted to a detector 9, and the signal is processed. In this constitution, since the signal from the receiving vibrator 3 and the signal from the receiving vibrator 5 are amplified by the same differential high frequency amplifier 15, the speed components in the radial direction are completely offset when the levels of the two input signals are the same. Even though the gain is fluctuated by temperature and power source voltages, the effects do not appear in the outputs.

Title: Ion-exchange treatment for electrodeposition paint bath
Inventor: FURUNO NOBUO
IPC: B01J47/14
Filed: 1986-02-21
Abstract: PURPOSE:To safely and efficiently remove the excess counter ions in the electrodeposition paint bath by detecting the difference in conductivity between the liqs. to be treated before and after a reaction tower, and maintaining the flow rate of the liq. at more than a specified valve so that the difference does not exceed the set value. CONSTITUTION:The difference in conductivity between the liqs. before and after the ion-exchange tower 15 is detected by cells 14 and 16, the outputs from the cells 14 and 16 are sent to a controller 19, and a signal showing the difference in the conductivity of the paint is outputted from the controller. The signal outputted from the controller 19 is sent to a pump 13, and the flow rate is regulated to control the flow rate, namely the space velocity, of the paint passing through the reaction tower 15. Since the total number of mols of removed ions per unit time is the product of the ion concn. in the raw liq. and the space velocity, the difference in concn. is decreased in inverse proportion to the SV value at more than a critical SV value. The difference in concn. between the raw liq. and the treated liq. is controlled to a desired value in this way while utilizing the capacity of the ion-exchange tower to the maximum.

Title: Radio transmission data receiver
Inventor: GOTO TADAMASA
IPC: H04B7/26
Filed: 1992-02-25
Abstract: PURPOSE:To attain stable data reception against an error in a specific code and a delay of a reception timing or the like caused by a characteristic change at a terminal equipment. CONSTITUTION:While reception data D1 are converted into parallel data by a serial/parallel conversion section 31, the data are outputted as serial data D2. A specific code detection matrix 32 monitors the parallel data to detect a specific code and generates a detection signal D3. On the other hand, the serial data D2 are stored in a buffer memory section 33 by a write clock control section 34 and read as output data D5 by a read clock control section 36 when the storage of a prescribed data quantity is detected by a counter section 35. Since the specific code is extracted based on parallel conversion data from the reception data, succeeding data reception is attained even to more or less error in the specific code and since the write/read of the reception data is implemented independently, a deviation in the data incoming timing is efficiently absorbed.

Abstract: PROBLEM TO BE SOLVED: To effectively use a memory by storing a change value of a pressure regulated value in a market with a factory value as a reference in a market value storage area of a nonvolatile memory, and initializing the storage area, thereby returning it to a factory set value in the market. SOLUTION: A combustion amount control means 1 judges a combustion mode by a mode switch 5, and reads a factory PWM(plus wide modulation) set data area 4a and market PWM change data area 4b of a nonvolatile memory 4 at each mode. Pressure regulation switches 6a, 6b are pressed. Thus, an initializing means 2 judges an initialization request of market PWM data to initialize the PWM change data of a decided combustion mode from the switch 5 at that time, and writes the data in the area 4b. At this time point, since (factory PWM data)+(market PWM data)=(factory PWM) is satisfied, the combustion amount can be returned to that at the time of shipping from the factory, and an LED 7a is deenergized so that return to the factory shipment value is confirmed.
