Title: Optical tweezers
Inventor: IKEDA MASAHIRO
IPC: G02B6/02
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To provide optical tweezers having an optical system which is comparatively simplified and capable of three-dimensionally moving an observation object to an optional position in non-contact state. SOLUTION: Light emitted from a laser light source 14 is guided by an optical fiber 11 through an optical connector 13, then, the light is emitted from the tip part 15 of the fiber 11 toward the observation object 2. The laser light emitted through the convergent exiting end part of the tip part 15 is converged at a beam waist position so as to be smaller than a beam spot size at exiting, so that a force in a beam waist position direction is applied on the object 2, then, the object 2 is caught, and by controlling a fine adjustment device 12 and three-dimensionally moving the optical fiber 11, the object 2 is operated to move.

Title: Magnetic head
Inventor: NIWA KAZUHIRO
IPC: G11B5/127
Filed: 1985-09-10
Abstract: PURPOSE:To reduce the crosstalks and to secure the satisfactory reproducing characteristics by setting the width of a magnetic part reaching at least to the magnetic gaps from the opposite edges of magnetic head cores at the values approximately equal to the track width. CONSTITUTION:The width of a magnetic part which is exposed over the rubbing surface of a recording medium reaching magnetic gaps 15a and 15b from the opposite edges 17a and 17b of magnetic head cores 11a and 11b is set at the value approximately equal to the track width. In other words, the molding glasses 16a and 16b are filled so that they cover a part of a rubbing surface up to the edges 17a and 17b of I-shaped core halves 13a and 13b. As a result, a magnetic edge producing a pseudo gap never covers plural tracks and the reproduction signal of an undesired track is never picked up in a reproduction mode. This can reduce the crosstalks and secure the satisfactory reproducing characteristics.

Abstract: PURPOSE:To constantly hold a signal voltage amplitude even at time of quick change of a light receiving level by connecting the collector of a transistor connected through a resistance to the output terminal of a high voltage generating circuit to an APD, controlling the base, voltage of the transistor, and controlling the bias voltage of the APD. CONSTITUTION:The collector of a transistor 5 is connected through a resistance 4 to the output terminal of a high voltage generating circuit 3, the emitter of the transistor 5 is grounded and the collector of the transistor 5 is connected to an APD(avalanche photo diode) 6. The output voltage of the peak detecting circuit impressed to a control terminal 1 is inverted and amplified by an inversion amplifying circuit 2 and impressed to the base of the transistor 5. At such a time, the output voltage of the high voltage generating circuit 3 is voltage- dropped by the collector current of the transistor 5, made into the bias voltage of the APD 6 and thus, the light current multiplication factor of the APD 6 is controlled. Thus, even when the light receiving level of the APD is quickly changed the signal voltage amplitude can be constantly kept.

Title: Detection of defective tablet
Inventor: MUKAI KIKUJI
IPC: G01B11/24
Filed: 1982-11-12
Abstract: PURPOSE:To spot defect of a tablet by detecting the speed of increase or decrease in the length of the cross line of a shade image of the tablet obtained from a detector such as image sensor to capture variation of the speed. CONSTITUTION:An image sensor 3 comprises an assembly of about 512-2,048 fine points and closely senses an shade image of a tablet passing thereover. In the relationship between passing tablets and the scan line of the image sensor, the tablet passing through the image sensor 3 in the direction A of movement is sensed by measuring the length (b) of the shade image in the scan line B. Simultaneously with the detection of the (b) on the image sensor, the speed in the increase or decrease thereof is calculated with a microcomputer connected to the image sensor. The Y axis represents changing speed of (b) and the X axis the elapse of time. In normal tablets 1-3, the Y value decreases gradually to a fixed value from infinite the moment the image sensor begins to sense an shade image of a tablet and goes to 0 when reaching two points. The Y value continues to decrease and approaches minus infinite at three points. Unless there is no defect in the tablet, the Y value won't move to increase.

Abstract: PURPOSE:To make it possible to perform measurement even in a solid-liquid dispersed system, by applying a specified force to a suspension, attaching fine grains on the surface of a filter, vibrating the filter in the direction along the surface, and measuring an AC signal generated between a pair of electrodes, which are attached to the filter. CONSTITUTION:A suspension to be measured is put in a container 2 so that an upper electrode 108 of a filtering electrode 1 is completely submerged. A motor 6 is driven, and up and down vibrations are imparted to the filtering electrode part 1 by a crank mechanism 5. Then a sucking pump 9 is driven, and a hollow part 104 is made to be a pressure reduced state. The suspension is sucked through a filter 105. Thus grains in the suspension are attached to the surface of the filter 105. The grains are vibrated with respect to the liquid. An AC potential corresponding to the vibration is generated at the electrodes 108 and 109 based on a streaming potential phenomenon. An ammeter 10 is connected between the electrodes 108 and 109. The interfacial potential of the fine grains, which are attached to the filter, is measured baded on the measured value of the AC. Thus the measurement without error can be performed even in the solid-liquid dispersed system.

Title: Image-forming device management system
Inventor: MIYAWAKI SHOZO
IPC: H04N1/00
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To improve the operability of an image-forming device management system by both of a central controller and a customer by providing a notification means with a that classifies the generated notification factors and differentiates the notification methods for automatic notification depending on the level. SOLUTION: A control section of image-forming devices 1-5 acts as notification means. When each of the image-forming devices 1-5 detects the occurrence of a fault, notification processing to notify the fact to a central controller 6 via a data communication equipment 7 and a communication channel 8 is conducted. Then the faults that have occurred are classified into levels, and it is discriminated whether each level is a level of 'an image-forming mode display is to continue as it is (a-1)' or a level of 'displaying a message related to automatic notification during automatic notification (a-2)'. If the level is (a-1), the processing is finished, while continuing the image-forming mode display of a character display device for an operation display section.

Title: Facsimile equipment
Inventor: KOUNOE TOSHIAKI
IPC: H04N1/00
Filed: 1988-08-12
Abstract: PURPOSE:To secure the high speediness of communication by providing a frame signal generating means to frame picture information to be supplied and insert a dummy signal by a dummy signal inserting instruction, a transmission means to transmit successively a frame signal and a timing means to execute a dummy signal inserting instruction when the threshold time lapses from the transmission completion of the previous frame signal. CONSTITUTION:Picture information 1 is framed by a frame signal generating means 4, a frame signal 2 is generated, and the generated frame signal 2 is successively transmitted by a transmitting means 5. At the ordinary time, without inserting a dummy signal, the frame signal 2 is generated and transmitted. When the generation speed of the frame signal 2 does not catch up with the transmission speed of the frame signal 2 and threshold time 6 passes from the transmission completion of the previous frame signal 2, a timing means 7 executes a dummy signal insertion instruction 3. Consequently, the frame signal generating means 4, as an exception processing, generates the frame signal 2 by the dummy signal insertion. Thus, while the high speed of the communication is secured, even when the picture information supplying speed at the transmitting side is slow, the communication can be surely performed.
