Patent JP-H0246087-A (JP)
Title: White balance adjuster
Inventor: SUZUKI MASAO
IPC: H04N9/73
Filed: 1988-08-08
Abstract: PURPOSE:To adjust white balance desirably in accordance with a photographing condition by providing a ripple detecting means and selecting a signal to be used also to form a gain control signal by the result of a detection. CONSTITUTION:When a ripple detecting circuit 44 decides that there is a ripple, switches 46 and 48 are connected to the (a) junction sides and conversely, when it decides that there is not the ripple, the switches 46 and 48 are connected to (b) junction sides. That is to say, when there is the ripple, control voltage generating circuits 38 and 40 form control voltages CB and CR from outputs logSB/SG and logSR/SG of differential circuits 34 and 36. When there is not the ripple, the control voltage generating circuits 38 and 40 form the control voltages CB and CR from an output logSR/SB of a differential circuit 42. By the control voltages CB and CR formed like this, the gains of amplifiers 24 and 26 are controlled and the white balance is adjusted. Thus, under fluorescent lamp illumination, a gain control considering a green signal level can be executed by using the differential circuits 34 and 36.

Title: Asr engine control device
Inventor: UKAI YOSHINORI
IPC: F02D41/04
Filed: 1992-06-30
Abstract: PURPOSE:To prevent the quick rise of engine speed even when an accelerator pedal is fully depressed when an ASR cut switch is turned on during the operation of ASR(Anti-Slip Regulator) engine control. CONSTITUTION:Degree of slip of a driving wheel is judged on the basis of a difference between the driving wheel speed and the car speed, and when the slip more than the predetermined quantity is generated in the driving wheel (time B), an ASR control lever position is moved to the side for limiting the injection quantity of a fuel injection pump (0 side). When the ASR control lever position is moved to the 0 side, the effective control range of the fuel injection quantity by an accelerator pedal is limited within a range expressed with oblique lines, and the rise of the driving wheel speed is restricted to prevent the increase of slip. In such an ASR engine control device, when the ASR cut switch is turned on (time D), the ASR control lever position is moved step by step by a predetermined quantity to the side (100 side) for increasing the fuel injection quantity.

Title: Fluorescent lamp driving circuit
Inventor: SUZUKI GIICHI
IPC: H05B41/16
Filed: 1994-07-29
Abstract: PURPOSE:To sense failure in a fluorescent lamp caused by the scattering of emitter material by decreasing the output current of an inverter in conformity with a control signal issued when the specified value is exceeded by the difference between voltages in both directions of the fluorescent lamp. CONSTITUTION:If the emitter of one of the electrodes, for example 14a, has worn much more than the emitter of the other electrode 14b, the lamp voltage V2 when current flows from the electrode 14b to the other 14a is greater than the lamp voltage V1 when the current flows in the opposite direction. The voltages V1, V2 are divided by resistances 15, 16, rectified and smoothened by diodes 17, 18 and capacitors 20, 19, and added together by resistances 21, 22, and when the voltage generated in another resistance 23 exceeds the voltages of zenor diodes 24, 25, the absolute value is sensed by resistances 27, 28, diodes 30, 31, and operation amplifier 32, and thereupon a thyristor 7 is actuated and transistors 3, 2 are stopped. Because the operation of an inverter is stopped, the current stops flowing to the fluorescent lamp 14.

Title: Ready mixed concrete placing hose
Inventor: TANAKA TAKAYUKI
IPC: F16L35/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To easily prevent a ready mixed concrete placing hose from being dropped on the ground. SOLUTION: A docking hose 20 connected to a transferring steel pipe 11, and a tip hose 30 connected to the other end of the docking hose are connected to a boom by tying wires 14 whose one end is fixed to the boom 10 to fasteners 23, 33 fixed to sleeve fittings 22, 32 of respective hoses. That is, since the fasteners are already attached to a ready mixed concrete placing hose, it is unnecessary to prepare a drop preventing fitting, and the measures of drop prevention can be performed only by connecting the wires to the fasteners, and it is very convenient for a hose user. Since the wires extending from the boom are fastened to the fasteners, safety confirming work is easy, and detachment of the wires is also easy. Moreover, since the fasteners are lightweight in comparison with the conventional drop preventing fitting, handling is easy, and cost is low.
