Title: Transmission method of stationary picture visnal telephone
Inventor: KANEKO KOJI
IPC: H04N7/14
Filed: 1989-02-13
Abstract: PURPOSE: To prevent black/white inversion in a reproduced image by inserting a phase inversion prevention signal consisting of a picture element signal corresponding to picture element data of a predetermined value to a prescribed position in the picture element signal, sending the resulting signal, and allowing a receiver side to detect phase inversion in a recovered clock based on a demodulated value. CONSTITUTION: A phase inversion prevention signal 3 consisting of a picture element signal corresponding to picture element data of a predetermined value is inserted to a prescribed position in the picture element signal of a still image, and a video telephone identification signal 1, a control information signal 2 and a phase inversion and picture element shift prevention signal 3 and a picture element signal 4 by processing length each are sent sequentially. A receiver side detects phase inversion in a recovered clock based on a value when the phase inversion prevention signal 3 is demodulated into picture element data based on the recovered clock extracted by a reception signal. Thus, black/white inversion in a reproduced image is prevented.

Title: Photosensitive body for electrophotography
Inventor: KAWAKAMI HARUO
IPC: G03G5/14
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To obtain a positive-charging single-layer organic electrophotographic sensitive body which is improved in the contactness between an uncut conductive base body and a photosensitive layer by forming an intermediate layer between the conductive base body and photosensitive layer. SOLUTION: The single-layer photosensitive body consists of a conductive base body 1, an intermediate layer 2, and a photosensitive layer 3. As the conductive base body 1, an uncut pipe is used in which various aluminum alloys are used and machining is not performed. The intermediate layer 2 stacked on the uncut conductive base body 1 serves to secure the contactness between the uncut conductive base body 1 and photosensitive layer 2 by coming into clone contact with the conductive base body 1 and photosensitive body 3 respectively. The material of the intermediate layer 2 should not electrically impede electric charge migration between the conductive base body 1 and photosensitive layer 3. The photosensitive layer 3 is composed principally of an electric charge generation material, an electric charge transporting material, and a resin binder. Consequently, the contactness between the uncut conductive base body 1 and photosensitive layer 3 is improved without spoiling photosensitive body characteristics.

Title: High frequency thermally cooking apparatus
Inventor: ENDO MINORU
IPC: F24C7/02
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To heat foods by high frequency energy and heat generated from a food carrier body by arranging a meshy food carrier body made of a material with a relatively high electric resistance such as nickel chromium in a heating chamber to make the carrier body generate heat by a high frequency current during the high frequency heating operation. SOLUTION: Upon the starting of high frequency heating, the temperature of roasted foods called 'gyohza' 10, 10, 10... rises gradually while receiving bars 8, 8, 8... rise in temperature by a high frequency current to heat the gyohzas by heat generated too. Traditionally, under a high frequency heating, watery state of finishing is unavoidable but this eliminates such a watery condition to allow crisp and flavorful state of finishing. Therefore, despite heating by high frequency energy alone with a high frequency oscillator 2, this enables utilization of heat generated from the food carrier body 6 made of a metal material with a large electric resistance thereby obtaining a flavorful state of finishing even in heating of frozen gyohzas or the like.

Abstract: PURPOSE: To obtain a miniature flow meter of simple structure suitable applicable to liquid sodium, etc., which has excellent linearity of its output signal, by providing small pieces of magnets near both ends of permanent magnets arranged with a pipe between.  
     CONSTITUTION: Permanent magnets 13a and 13b sandwiching pipe 11 with internally stuck insulating material 12 are positioned by magnet supporters 14a and 14b. Once a conductive fluid flows in a magnetic filed provided by permanent magnets 13a and 13b, a voltage proportional to the flow rate of the fluid is developed between a couple of electrodes on the same pipe sandwiching pipe 11. In this case, small magnet pieces 15 are so arranged near both ends of permanent magnets 13a and 13b that a magnetic field in the same direction as that of the magnetic field provided by permanent magnets 13a and 13b will be formed. Thus, the linearity of the output voltage can be improved by decreasing an eddy current due to the terminal effect of the permanent magnets.

Abstract: PURPOSE:To avoid unidirectional line interruption in any case of a call from a non-telephone set or a telephone set by selecting the nontelephone set or the telephone set based on a selection signal, sending a ring signal after the terminal set is switched to apply the line acquisition of the terminal set. CONSTITUTION:When a call comes from a telephone line L, a ring detection circuit 11 detects a ring signal via a switch 7 and a changeover equipment 6 and a control circuit 12 acquires the line. When a sender side is a non- telephone set, no signal comes from a detection circuit 16 of a selection signal discrimination circuit 13 to the control circuit 12, the control circuit 12 switches the changeover equipment 6 and energizes a ring transmission circuit 5. Thus, the ring signal is sent to the non-telephone set 2 and the sender side and the non-telephone set 2 acquires the line. When the sender side is a telephone set, since a voice signal is sent in succession to the ring signal, a signal component is outputted from the detection circuit 16, the control circuit 12 switches the changeover equipment to the position of the telephone set 3 and the changeover equipment 6 and the ring transmission circuit 5 are controlled similarly. Then the hook switch 8 stops the ring signal transmission by hooking of the telephone set 3 to connect the telephone set 3 to the line.

Abstract: PURPOSE: To prevent variations in the output of a semiconductor laser due to changes in the characteristics of the laser by driving the semiconductor laser in such a manner as to eliminate difference between the output and a modulated signal after it is photoelectrically converted with a photodetector and the resultant electrical signal is amplified.  
     CONSTITUTION: The output of a semiconductor laser 1 is detected with a light detecting device 103 (photo diode or the like) converted into an electrical signal which is amplified with an operation amplifier and outputted. The output is applied to an inversion input terminal of a comparator 100 via an inverter 101 to drive a semiconductor laser 1 in such a manner that it equals a modulated signal to be applied to a noninversion input terminal. If an output of D is to be obtained with an input current of C, any change in the characteristics of the laser, for example, from D 1 ' to D 2 ', can be detected with the light detecting device 103 to vary the input current of the laser 1 to C' with the comparator 100. In this manner, the laser is maintained to provide the output D constantly.
