Title: Water amount detecting apparatus
Inventor: KOJIMA NOBUYUKI
IPC: G01F23/26
Filed: 1989-09-18
Abstract: PURPOSE:To correctly detect the amount of water a container by directly connecting an end of each electrode to a capacitor terminal of an oscillating circuit. CONSTITUTION:Terminal protrusions 11, 12 are formed at respective lower ends of a pair of electrodes 4, 5 which are mounted confronting to a water guide pipe 3. An IC of an oscillating circuit 9 is provided in a circuit substrate 13. Moreover, holes 14, 15 are formed in the circuit substrate 13 to which the protrusions 11, 12 of the electrodes 4, 5 are fitted. The protrusions 11, 12 fitted into the holes 14, 15 are soldered and connected to a pattern of the substrate 13. In this structure, the capacitance of a capacitor of the circuit is not influenced by a conductive wire at all and approximately equal to the capacitance between the electrodes 4, 5. When the water level the pipe 3 is changed by the change of the amount of water in the container, the capacitance between the electrodes 4, 5 is accordingly changed and the capacitance of the capacitor of the circuit 9 shows correct change. Consequently, the oscillating frequency of the circuit 9 is changed, and therefore the amount of water within the container can be correctly detected by detecting the oscillating frequency of the circuit 9.

IPC: G02F1/133
Filed: 1993-09-02
Abstract: PURPOSE:To realize uniform color medium contrast display free from variations and color slurring by providing the color liquid crystal display device with a driving means for digitally changing the inversion area of the liquid crystal display device and a threshold fluctuation compensating means for elements. CONSTITUTION:A ferroelectric liquid crystal FLC which causes a phase transition by temp. is arranged between a scanning electrode 201 and an information electrode 202. The data transmitted from a graphic controller 107 are inputted through a driving control circuit 105 to a scanning signal control circuit 104 and an information signal control circuit 106, by which the data are respectively converted to an address data and a display data. This FLC causes the phase transition with the temp. and can display 9 gradations. Since the element is so set as to digitally (stepwise) change in the threshold with the impressed voltage and, therefore, the error by the fluctuation in the threshold characteristic is absorbed if the impressed voltage of the respective gradation displays us set at the middle of the stepwise changing threshold. The generation of the error in the display is thus obviated.

Title: Facsimile transmission form and information transmission method using facsimile
Inventor: TAMAI SHINPEI
IPC: H04N1/00
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To keep the secret of transmission information and to prevent the leakage of the secret by displaying a camouflage pattern to make it difficult to read the written characters or numeric characters at least on part of a transmission information entry part of a facsimile transmission form including an information entry part on its surface. SOLUTION: A request to enter a credit card number at a credit card number entry part 8 of a facsimile transmission form 1 are lightly printed by means of the drop-out ink. Thus, the mentioned items cannot be read at the receiving side even when the form 1 is erroneously transmitted and accordingly a third person who received the form 1 cannot understand a numeric character entry area display 8a of the part 8. As a result, the secret of transmission information can be kept. In addition to the part 8, the displays 8a are printed and displayed in a number equal to the necessary telephone numbers at a telephone number entry part 6, for example. Thus, it is possible to prevent the leakage of secret that is caused by the wrong transmission of a telephone number.

Title: Front and rear wheel steering device
Inventor: KOMAMURA SEIJI
IPC: B62D7/15
Filed: 1985-10-28
Abstract: PURPOSE:To control precisely steering power for rear wheels and enable the precise and optimum steering of wheels on a simple constitution by adjusting a bypass amount through the control of a variable throttle opening and regulating hydraulic pressure from an actuator for rear wheel steering. CONSTITUTION:Hydraulic pressure to be supplied to a power cylinder 12 for steering rear wheels is controlled by increasing or decreasing the opening of a variable throttle 15 depending upon a driving condition and adjusting a bypass amount from high pressure side to low pressure side. Therefore, steering power for rear wheels 10 can be controlled independent of steering power for front wheels 3 and that precisely to suit a driving condition. In particular, control characteristics for the rear wheels 10 can be freely and precisely adjusted by only the supply side opening of the throttle 15, for example, by increasing or decreasing the opening depending upon a car speed, because a return circuit from the power cylinder 12 is not throttled. Consequently, the proper and optimum steering of the rear wheels 10 is ensured by a simple constitution.

Filed: 1993-09-28
Abstract: PURPOSE:To stabilize and align segments by engaging a deflection stopper mechanism with a bolt mounting groove of a clamping segment and attaching a fixing mechanism that fixes the clamping segment with a segment guide. CONSTITUTION:After a clamping operation of a clamping segment 10 is finished, and a deflection stopper jack 60a is extended, a fixture 60b swings clockwise, centering on a pin 60d, thereby pushing down a rubber material 60c so that it may enter a bolt mounting groove 10a of the clamping segment 10. Then, the rubber material is pressed on a wall surface. As a result, the rubber material 60c is engaged with the mounting groove 10a, thereby fixing the clamping segment 10 with a segment guide 30. When the clamping segment is aligned with an existing segment 11 with an erector 2, the clamping segment 10 does not deviate in either of the axial directions or either of the circumferential directions, and it will be held in a definite position constantly. This construction makes it possible to provide the erector 2 for a shield jacking machine capable of making a stabilized alignment.
