IPC: B60H1/32
Filed: 1989-03-10
Abstract: PURPOSE:To enhance the sense of accelerating due to acceleration control by comparing the sensed value of evaporator thermal load with the specified value, disengaging a compressor clutch when the thermal load is small, and decreasing the discharge capacity of compressor when the thermal load is large. CONSTITUTION:The inlet air temp. Ti and outlet air temp. Te of an evaporator 3 are sensed by thermistors 16 and 17, respectively, and fed to a microcomputer 14. The evaporator outlet target air temp. Teo is computed from the inlet air temp. Ti, and the voltage to be impressed on a solenoid valve of a control valve 10 is determined on the basis of its difference from the sensed outlet air temp. Te. An engine control circuit 18 judges whether acceleration exists.

Title: Clip for collectively holding down thin metallic plate, etc.
Inventor: JIYOZEFU MUDAARU
IPC: F16B5/04
Filed: 1989-03-10
Abstract: PURPOSE: To increase the life of a clip by forming the clip from a freely deformable material, and constructing it from a protecting tube surrounding slender elements including hooking beaks. CONSTITUTION: When a protecting tube 15 is introduced through opposite holes 19-21 in sheet metal plates 22-24, the lateral relative displacement between a main body 1 and blades 7, 8 results in compression of an assembly of the plates 22-24 between a bearing face 5 and a flange 17 on one hand and in local radial deformations 25, 26 on the protecting tube 15 on the other hand, which are caused by the radially increasing interval between hooking beaks 9, 10. Therefore, the hooking beaks 9, 10 make contact on the periphery of the hole 21 in the plate 24 via the deformed portions 25, 26 of the protecting tube 15. Then the plates 22-24 are mutually compressed by a spring 13. Since the protecting tube 15 is made from a resiliently deformable material, the deformed portions 25, 26 are eliminated on removal of a clip and reuse is made possible.

Title: Brake control device
Inventor: TAKAYAMA TOSHIO
IPC: B60T8/58
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To stabilize the behavior of a vehicle by applying the constitution that a control signal for a smaller braking force generated with a target deceleration coincidence control means or a slip ratio control means is selected at an ABS control process and a braking force is thereby generated. SOLUTION: A control device 100 has a slip ratio control means 102B to perform ABS control, in addition to a target deceleration coincidence control means 102A. In addition, a selector control means 102C selects a control signal for a smaller braking force, generated with the target deceleration coincidence control means 102A or the slip ratio control means 102B when the ABS control is under way, and then outputs the signal to a feedback control means 102D. Thus, when any of wheels 22, 24, 38 and 40 tends to lock and subsequently a control signal from the slip ratio control means 102B is selected for reducing a generated braking force, a wheel slip ratio is controlled so as to be within an allowable range. According to this construction, the wheels 22, 24, 38 and 40 are prevented from falling in a locked state.

Title: Optical comparator
Inventor: TERASAWA TOMIZOU
IPC: G01D5/36
Filed: 1984-03-24
Abstract: PURPOSE:To remove the effect of the change in the intensity of an optical signal by making a comparison reference voltage follow up the change in a photoelectric conversion signal level to be compared which accompanies the change in the optical signal. CONSTITUTION:When first to third optical signals (a)-(c) are approximate sine waves, for instance, an output signal Va of a first inversive amplifier 5 becomes a sine wave as shown in Fig. (a), while output signals Va of second and third inversive amplifiers 6 and 10 become since waves shifted in a phase of 180 degrees from the one of Fig. (a). The output signals of the amplifiers 5 and 6 are put in an adder 7 and added up thereby to be an output of Va/2, which turns to be a comparison reference voltage of a comparator 11, while the output signal from the amplifier 10 turns to be a comparison voltage. The output of the adder 7 turns to be a non-inverted input signal of the voltage comparator 11, while the output of the amplifier 10 turns to be an inverted input signal. By making the comparison reference voltage of the voltage comparator 11 follow up a change in an input signal to be compared, in this way, an optical comparator having a stable accuracy in detection irrespective of a change in the intensity of an optical signal can be realized.

Abstract: PURPOSE: To enable accurate coil diameters to be measured by adding the correction of overwinding within the time when strip form material passes between two points  at the time of measuring the coil diameters from the rotating angles of a take-up  machine within said time.  
     CONSTITUTION: Pass detectors 3 and 4, which are positioned apart at the preset distance LA, detect that the trailing end of the strip form material being taken up on a take-pu machine has passed said positions and input their output to a counter circuit 10 via gate circuit 8. The counter circuit 10 integrates the output signals from a rotating angle detector 7 only while the trailing end 2 of the strip form material is passing between the pass detectors 3 and 4. The coil diameters are operated in an arithmetic circuit 11. A correction circuit 12 performs operations based on the value of the coil diameter D given from the arithmetic circuit 11 and the value of the plate thickness measured in a plate thickness measuring instrument 13, corrects the overwinding quantity owing to the plate thickness of the strip form material and calculates the correct coil diameter D c .
