Title: Brushless motor
Inventor: FUJII HIROKAZU
IPC: H02K29/00
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To allow a rotor and a stator iron core, which face each other at a very small space, to be at the same potential, prevent the appearance of sparks in the small space, and prevent insulation breakdown between the stator iron core and a printed wiring board, by electrically connecting the stator iron core and a bracket. SOLUTION: A stator 5 is made by forming a printed wiring board and a stator iron core, around which a winding is wound, from thermosetting resin into an integral unit. The stator 5 is so formed that a non-contact section 3a may be exposed outside and is provided with a recess 5a in conformity with the shape of a bracket. A bearing bracket 11 has a projecting section 11a, a part of which is so bent as to allow the stator 5 to be brought into contact with the non-contact section 3a when it is mounted on the stator 5. By this method, the bearing bracket 11 and the stator 5 can be easily assembled and they are allowed to be at the same potential. As the stator 5 has such a shape that a part of the external side face of the stator iron core may be exposed, the stator iron core and the bearing bracket can be brought into contact with each other without forming a non-insulated section.

Title: Biosensor
Inventor: TAKEI FUMIO
IPC: G01N27/327
Filed: 1985-09-18
Abstract: PURPOSE:To measure an objective specific substrate with high accuracy, by immobilizing the enzyme for recognizing the specific substrate and the enzyme for converting the substance obstructing the detection of the specific substrate to an innoxious substance in an enzyme immobilizing membrane. CONSTITUTION:The enzyme catalyzing the specific reaction with a specific substrate to be measured and the enzyme for converting the substance obstructing the measurement of the specific substrate to an innoxious substance are simultaneously immobilized in the enzyme immobilizing membrane of a biosensor. For example, ascorbic acid oxidase is immobilized in an enzyme fixing membrane for detecting glucose along with glucose oxidase. Even if ascorbic acid is present in a liquid specimen, ascorbic acid is oxidized by ascorbic acid oxidase to be prevented from obstructing the detection of glucose. Because the biosensor is constituted so as to remove the action of the substance obstructing the substance can be measured with high accuracy.

Title: Liquid crystal device and its production
Inventor: YOSHINO TAKESHI
IPC: G02F1/1343
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of transparent electrode patterns on a substrate for a liquid crystal panel of a liquid crystal device and the throughput in production by executing exposure of a resist plural times. SOLUTION: A transparent conductive film 2 is deposited on the substrate 1 for the liquid crystal panel consisting of glass, etc., and the resist 3 is applied on this transparent conductive film 2. The resist 3 is exposed by using a mask 4 and only the exposed portions 3b among the resist 3 are selectively dissolved away and are developed by using an alkaline developer. The unexposed portions 3a of the resist 3 made to remain are sensitized and is changed in properties by executing non-selective exposure not using the mask. These parts are post baked as the second exposed parts 3c having the nature liable to dissolve in an alkali. The transparent conductive film 2 exclusive of the coating portions 2a covered with the second exposed parts 3c of the remaining resist 3 is removed by etching by using an acidic etchant.  The second exposed portions 3c of the resist 3 covered on the surface of the coating portions 2a of the transparent conductive film 2 are dissolved and peeled by using an alkaline peeling liquid.

Title: Solid-state image pickup device and its drive method
Inventor: UENO HIROYUKI
IPC: H04N5/335
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To avoid mixing of sweep-out signal charges to a read signal charge in the case of transit to drive all picture element read by generating a sweep-out pulse just after reading the signal charge so as to sweep out the remaining signal charges. SOLUTION: Since a stored signal charge amount of a sensor section 1L depends on a height of a potential barrier depending on a bias charge applied to a substrate, a bias voltage Vsub is applied to the substrate. In the case that the stored charges of the sensor section 11 are simultaneously swept out, a high voltage charge sweep-out pulse Xsub is superimposed onto the voltage Vsub via a capacitor C, a potential barrier is destroyed to sweep out the stored signal charge. The pulse Xsub is used for a shutter pulse for exposure time control. A timing generating circuit 17 provides a read pulse for a period of a vertical transfer clock ϕV2 in the interleave read mode, and provides the read pulse for a period of a clock ϕV2' in the full picture element read mode, reads the pulse Xsub and outputs it just after the pulse is outputted and the signal charge remaining the interleave read drive is swept out.

Title: Charge coupled device
Inventor: KIMATA MASAAKI
IPC: G11C19/28
Filed: 1986-08-29
Abstract: PURPOSE:To reduce kTC noise by making reset operation longer than the driving clock period of a charge coupled device. CONSTITUTION: If a reset clock phiR is given to a switch 7 when a clock phiC which is inputted to the control terminal 72 of the switch 7 is at high level, a high level signal is outputted from the output terminal 73 of the switch 7 and a reset signal is given to a gate 4 and the output Do of a transistor Qo takes the highest potential. When the output 73 of the switch 7, i.e. the AND output of the clock approx.=R and the clock phiC, is changed to low level, the level of the output potential Do is declined a little by the capacitance coupling between the gate electrode 4 and a floating diffusion 6. After that, when a clock phiH is turned to low level, charges in a charge coupled device are successively discharged into the floating diffusion 6 and the level of the output Do of the transistor Qo is declined to a required level so that the level of the output Do can be maintained.

Title: Controller for rolling of paddy working machine
Inventor: MISHIRO MITSURU
IPC: A01C11/02
Filed: 1988-08-19
Abstract: PURPOSE:To regulate tilting of a planter and maintain a horizontal posture by urging a spring for regulating left and right tilting of the planter with a hydraulic expanding and contracting mechanism operating in interlocking with reciprocation and transverse movement of a seedling carrier. CONSTITUTION:When a seedling carrier 12 is moved to the left in the forward passage, a spring 35 on the projecting side of the seedling carrier 12 is gradually elongated in interlocking with movement of the seedling carrier 12 to increase urging force. Thereby, the seedling carrier 12 is held in a horizontal position without tilting to the left. A changeover valve on the side linking to a hydraulic expanding and contracting mechanism 29, however, is changed over to a 'lifting zone (U)' at a position of about 1/3 of the mat seedling width before leading to the left travel end. Thereby, a piston (29b) of the hydraulic expanding and contracting mechanism 29 is slowly lifted to elongate the spring 35 on the projecting side and increase the urging force of the spring 35. As a result, tilting of the planter can be regulated to maintain the horizontal posture of the planter without applying a load to floats.

Filed: 1988-08-18
Abstract: PURPOSE:To enable the easy follow-up of the illuminating direction of an illuminating light to the movement of an object by providing a gaze direction detecting part and a control part and controlling a driving part based on the signal from the gaze direction detecting part. CONSTITUTION:A control part 6 inputs a signal from a gaze direction detecting part 5 and outputs a signal controlling a driving part 3 so that the illuminating direction of the illuminating light from a light source 1 accords with the gaze direction of an observer. The frequency band range of fine vibrations of the human eye is 10-20Hz and 70-90Hz, although it varies depending on the state of the observer. Thus, in the control part 6, the above two band range components of the signals from the gaze direction detecting part 5 are removed, and the driving part 3 is controlled based on the resulting signal. Hence, the rapid follow-up to an object 4 can be achieved without insignificantly moving the driving part 3 due to fine vibration of the eyeball of the observer.
