Title: Integrated instrument control system
Inventor: NAKAMOTO TOSHINOBU
IPC: G05B15/02
Filed: 1988-03-14
Abstract: PURPOSE:To increase a display response speed against an operation in accordance with the number of connecting sets by changing and setting a transmission period of manipulated variable data in accordance with the number of connecting sets of a controller station and an operator station. CONSTITUTION:An operator station 2 inputs a controller station 1 to an increase/decrease buffer 6 by a data collecting means 5, displays its contents on a CRT monitor, and thereafter, sets a counter to '1'. In case a request has been received from an operating key 8, the contents of the buffer 6 are varied by an increase/decrease means 7, and its contents are displayed on a monitor 10. Subsequently, by a connecting set number deciding means 13, in accordance with the number of connecting sets of the station 1 and the station 2 which have been connected to a bus line 3, a transmission period of data is determined by a transmission period determining means 14. In this case, in case the number of connecting sets is large, the transmission period is lengthened, and in case the number of connecting sets is small, the transmission period is shortened.

Title: Ultrasonic object detector
Inventor: YAMANE TOSHIKI
IPC: G01S15/04
Filed: 1988-03-15
Abstract: PURPOSE:To decrease the probability that the ultrasonic pulses from the other detector intrude into a limiting gate by constituting the above detector in such a manner that a limiting gate setting section judges the approach of an object and sets the width of the parting direction of the limiting gate to receive the ensuing reflected waves when the reflected wave is received in the shortest distant detecting part of the detecting gate and limiting gate. CONSTITUTION:The ultrasonic pulse which is transmitted when an ultrasonic wave oscillator 1 for common use as wave transmission and reception is driven by a wave transmission driving circuit 3 and is reflected by the object 11 is received in the detecting gate set 4a in the range of the specified time delay from the point of the time when the transmission of the ultrasonic pulse is started. The width of the approaching and parting directions to and from the set position and the position where the reflected wave is received is then changed according to the approaching and parting of the object 11 and the limiting gate is set 4c in the range near the previously received range at the time of the transmission of the next ultrasonic pulse. The reflected waves are received continuously several times within this limiting gate and the presence of the object 11 is decided 4d. The distance to the object 11 is determined by the decision section 4d and whether the object 11 is approaching or parting is decided.

Title: Package for containing hybrid integrated circuit element
Inventor: UEDA YOSHIAKI
IPC: H01L23/50
Filed: 1986-03-18
Abstract: PURPOSE:To prevent the generation of cracks and fractures in electric insulating material completely, by forming outer lead terminals by a double structure, wherein a core body comprises a metal, whose resistivity is 5.0muOMEGAcm or less, and a coating body comprises a metal, whose Vicker's hardness is 170 or less. CONSTITUTION:A package comprises a metal base body 1, outer lead terminals 4 and a metal cap 2. At this time the terminal 4 has a double structure comprising the following parts: a core body 4a comprising a metal, whose resistivity is 5.0muOMEGAcm or less; and a coating body 4b comprising a metal, whose Vicker's hardness is 170 or less. When the element is operated, most of the current flows through the core body 4a having the low resistivity even if a large current flows through the terminal 4. Therefore much Joule's heat is not generated. Thus, the generation of the cracks and fractures in electric insulating material, which holds the terminals 4, can be prevented completely.

Abstract: PURPOSE:To prevent the cracking of the substrate layer and to prevent the corrosion due to residual ions by forming an alumite coated film on a substrate of aluminum or its alloy in <=3mum thickness and vapor-depositing a cobalt alloy thin film thereon. CONSTITUTION:A hard alumite layer is formed on an aluminum substrate or an aluminum alloy substrate in <=3mum thickness. a magnetic thin film of a cobalt alloy such as Co-Ni is formed on the substrate layer of alumite by vapor deposition or sputtering. Consequently, since the thin alumite film is used for the substrate layer, cracking is not caused, even when the internal stress is increased due to the temp. rise during the production. Moreover, a large amt. of ions do not remain and hence the corrosion of the alloy thin film can be prevented.

Abstract: PURPOSE:To enable a user to easily and properly adjust gradations of black-and- white gray level by using a gamma correction value determined so that gradations of read data of an output gradation bar chart approximate gradations of read data of a reference gradation bar. CONSTITUTION:The reference gradation bar 8 is read by a scanner 11 and stored in a storage part 13a, and the read data are printed out by a printer part 14 to obtain the output gradation bar chart 17.

Filed: 1982-04-14
Abstract: PURPOSE:To automatically switch an operation to 4-wheel driving and always perform the selective operation at the beginning of occurrence of a slip, by comparing angular acceleration of a wheel in accordance with a reference value of a car speed and deciding a pressure of the slip in driven wheels. CONSTITUTION:A rotary sensor 40 is provided to front wheels operated as the driving wheel at 2-wheel driving to detect a wheel speed. On the basis of this detection, a car speed detector circuit 43 computes a car speed to correct the reference value of a reference value setter circuit 44. Angular acceleration of the wheel is computed by an angular acceleration detector circuit 41 and compared with a reference value in a comparator 42. If a slip of the wheel is output by the comparator 42, a solenoid 32 is operated by a switch 38 to select operation to 4-wheel driving. Since selective operation to the 4-wheel driving is performed when the fixed slip in accordance with the car speed is generated, operation can be accurately switched to the 4-wheel driving even at a high speed.

Filed: 1992-03-19
Abstract: PURPOSE:To prevent erroneous reading and data destruction. etc.. from occurring by storing a fixed character or pattern in a specific address part when initialization is performed, and always checking storage data. CONSTITUTION:(00)16 data is stored in the (00000)16 address that is the least significant order of a memory card, and (FF)16 data in the (1FFFF)16 address that is the most significant order when the initialization is performed. When checking is performed, the content of the (00000) 16 address is read to a register, and it is checked whether or not the content of the register is (00) 16. By performing such processing, the (00)16 data can be checked out since it is read in as (08)16 data when it is read due to the contact defect of a connector on a data bus, assuming certain bits, for example, 2<3> bits are set as one-fix. Similarly, when the 2<3> bits are set as zero-fix, the data can be checked out since it is read as (F7)16 data when the (FF)16 data is read.

Abstract: PROBLEM TO BE SOLVED: To compensate the effect of irregularity to the current transmissibility of a photocoupler. SOLUTION: Input voltage A is converted into a primary current by a voltage-current converter 1, and the light emitting element 2a of a photocoupler 2 is driven by the primary current. The light receiving element 2b of the photocoupler 2 receives the light generated by the light emitting element 2a and outputs a secondary current; the secondary current is proportional to the primary current and depends on the current transmissibility of the photocoupler 2. There is irregularity in every photocoupler in the current transmissibility, and accordingly, the secondary current possesses the magnitude depending on the current transmissibility of the photocoupler 2 to be used.  From the voltage generated on the fixed resistor 3 by the above-mentioned secondary current, AC voltage X is extracted on one hand by a capacitor 4, and DC voltage E is extracted on the other hand by being fed to a DC detector 5. The AC voltage X is divided by the DC voltage E, by a dividing machine 6. The AC voltage of the output Z of the dividing machine 6 is not affected by the current transmissibility of the photocoupler 2.
