IPC: G01M3/04
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To faciliate the construction, reduce the cost, enhance the durability, and also provide a high detecting precision over a long period. SOLUTION: In a procedure S1, the impedance of a part where a water leakage detecting laminated sheet is arranged is measured by a measuring person to form an impedance distribution chart. When a water leakage detecting laminated sheet is broken, processings of procedures S3-S4 are performed. In the procedure S4, the impedance between a plurality of electrodes provided and the internal electrode of the leakage detecting laminated sheet is measured. In the procedure S4, the equal impedance line according to the above measurement result is determined on the basis of the impedance distribution chart. In a procedure S5, a processing for specifying the broken part is performed on the basis of the equal impedance line determined in the procedure S4.

Title: Laser diode driving circuit
Inventor: TANAKA HARUO
IPC: H03K17/62
Filed: 1992-01-13
Abstract: PURPOSE:To drive a laser diode always by a constant current, by using elements wherein the impedance of a first series circuit and that of the second series circuit become nearly equal. CONSTITUTION:In a laser diode driving circuit wherein a laser diode LD is driven by the ON-OFF operation of a second switching element Q2, elements are used in which the impedance of a first series circuit 5 when a first switching element Q1 turns ON becomes nearly equal to the impedance of a second series circuit 6 when a second switching element Q2 turns ON. Thereby a current flowing from a constant current source 1 when the second switching element Q2 is in the ON state becomes equal to a current when the first switching element Q1 is in the ON state. Hence the current flowing through a laser diode LD when the second switching element Q2 is in the OFF state and the first switching element Q1 is in the ON state becomes constant.

Title: Adsorption conveying apparatus
Inventor: UJITA YOSHIHARU
IPC: B25J15/06
Filed: 1984-01-12
Abstract: PURPOSE:To prevent double suction of plate pieces caused in case of sucking and conveying a comparatively thin plate piece in addition to a thick plate piece by disposing a small-diameter suction pad inside a trumpet-shaped large-diameter suction pad substantially concentrically. CONSTITUTION:Air is sucked from an air suction pipe 4 on large-diameter suction pad 1 side by operation of a valve 6, so that a thick plate is sucked and conveyed by strong suction extending over the wide range produced by the large-diameter suction pad 1. In this case, an air suction pipe 5 on smll-diameter adsorption pad 2 side is blocked up. In case of sucking and conveying a thin plate, the lower end outer peripheral edge portion 3 of the large-diameter suction pad 1 is elastically deformed to bring the small-diameter suction pad 2 into contact with the surface of a thin plate 7. After that, air is sucked from the air suction pipe 5 on the small-diameter adsorption pad 2 side by operation of the valve 6, so that only the uppermost thin plate 7 is bent and deformed in the small-diameter suction pad 2 by strong suction extending over the small range produced by the small-diameter suction pad 2, whereby an air layer 8 is produced between the thin plate and the lower thin plate 7 to prevent double-suction.

Title: Recording device
Inventor: SAKAI TOSHIO
IPC: G03G15/05
Filed: 1984-01-14
Abstract: PURPOSE:To suppress the dirt of the ground of a body to be transferred and to suppress the reduction of resolution by arranging a slit member having a slit between a toner layer carried by a toner carrier and the body to be transferred and applying voltage having the same polarity as that of toner to be transferred to the slit member. CONSTITUTION:The slit member 11 is arranged between the toner layer 3 carried by a toner roller 1 and transfer paper 10. The slit 12 extended in the axial direction of the toner roller 1 and a transfer roller 9 is formed on the slit member 11 in an area opposed to both the rollers 1, 9. In addition, voltage having the same positive polarity as the charged polarity of the toner to be transferred is applied to the slit member 11. Consequently, a reverse transfer field reversed against a transfer field is formed between the slit member 11 and the toner roller 1. The intensity of the reverse transfer field is set up lower than the strength of the transfer field to prevent the toner charged with negative polarity on the toner roller 1 from being moved to the slit member 11.

Title: Device for forming frying ingredient
Inventor: OKAMOTO TAKESHI
IPC: A23P1/00
Filed: 1979-01-17
Abstract: PURPOSE: To frying ingredient is placed on a belt conveyor sufficiently flexible to turn into a cylinder when it passes through the ingredient-forming part with a cylindrical space and is formed into a certain shape, thus facilitating the later processes.  
     CONSTITUTION: Belt conveyor 5 carrying frying ingredient F, e.g., shrimps, moves in the direction of arrow W. When the conveyor comes near the part for forming the frying ingredient 8, the both edges of conveyor are lifted by the action of rolls 9 and 10 and the parts of belt 5a are bended insides. Then, when the ingredient F is conveyed right before the part 8, it is formed by rollers 9 and 10 so that it can passes through the cylindrical space between rollers 9 and 10. At this time, the parts of belt 5a come into contact with each other at the edge and wrap the ingredient F and the part for regulating the length of the ingredient 6. When the ingredient passes through the cylindrical space 13, the ingredient F is compressed to contract the outer diameter and stretch the length so that the cross section and length become the same as the cross section of the part 6 and length between parts 6 respectively.

Title: Travelling apparatus for rice planter
Inventor: TANI MASAKAZU
IPC: A01C11/02
Filed: 1979-01-17
Abstract: PURPOSE:To provide a travelling apparatus for a rice planter, wherein a pair of propelling wheels are supported freely vertically movably contrary to the body having a rice planting mechanism, and floats are arranged between the wheels and on both outer sides of the wheels under the body, so that the stabilization and  straight travelling characteristic of the rice planting posture will be improved. CONSTITUTION:Wheels 4, 4 at both sides of the body having a rice planting mechanism 2 are supported by free ends of transmission and wheel supporting cases 10, 10 which are pivotably mounted to the body. The free ends are coactively joined with a hydraulic lock expansion mechanism 18 through link levers 16, 16 and link mechanisms to connect the supporting cases 10, 10 vertically movably contrary to the body. Between the wheels 4, 4 and on both outer sides of the wheels 4, 4 are arranged floats 5; 6, 6 so that forward portions of the floats can independently move vertically, e.g. with rear portions thereof serving as their fulcrums. Thus if pressure of ground contact of the wheels is changed the wheels will not slip but move to follow along a hard ground, and coact with the floats to prevent disordered rice planting posture due to listing of the body.

Title: Safety device of unattended carrying car
Inventor: SUZUKI OSAMU
IPC: B60L15/40
Filed: 1981-01-14
Abstract: PURPOSE:To prevent a detection error of an object at the outside of a passage and to exactly detect an obstacle in the passage without widening a space of the passage, by turning a contactless detector to the inside of a carved part when running on the curve, and after that, resetting it. CONSTITUTION:A carrying car position counter 13 counts a position of a carrying car 4 from a wheel rotating pulse 12. Reference position signals 14a-14c show, for instance, absolute positions based on a station, and whenever passing through the station, a carrying car position signal 13a is corrected to a value of the signals 14a-14c. The carrying car 4 reaches this side of a curved part 2a, and at the time of a signal 15a<= the signal 13a, an output of a comparator 16a becomes H, a motor 8 for a detector is rotated by a controlling circuit 17a, and a contactless detector 5 is turned to the inside of the curved part 2a. As a result, a detection range of an ultrasonic wave 5a is directed into the curved part 2a exactly, and when said detector passes through the center, it is turned to the outside. Accordingly, not only an obstacle in a passage is detected exactly but also a detection error of an object at the outside of the passage is prevented.
