Title: Device for discriminating use state of film cartridge
Inventor: YOSHIDA YUTAKA
IPC: G03C3/00
Filed: 1993-10-20
Abstract: PURPOSE:To provide a device for discriminating the use state of a film cartridge whose discriminating accuracy is improved. CONSTITUTION:When the film cartridge is loaded in the cartridge chamber of a camera and a cover for loading is closed, a photosensor is driven by detecting the presence or absence of the film cartridge and receiving the detection signal. The position of a display board is detected by the photosensor and an output current value from the photosensor is read. When 0.5 seconds elapses after starting the feed of film, the position of the display board is detected by the photosensor again. The output current value at this time from the photosensor is read. When a difference between the two output current values is equal to or larger than a specified value, a motor for feeding film is normally rotated, and the first frame of the film is set at an aperture. When the difference between the two output current values is smaller than the specified value, the motor is reversely rotated, and the film is rewound, while a warning that the film has been used is displayed. The reverse rotation of the motor is stopped after 2 seconds.

Title: Image signal processor
Inventor: NAKANO MAKI
IPC: H04N5/91
Filed: 1990-09-28
Abstract: PURPOSE:To accurately execute stable temp. compensation by providing this interpolating image signal forming circuit and a skew compensating circuit and compensating the temp. characterists of the 1st and 2nd delay lines inlcuded in both the circuits by a single temp. compensating circuit. CONSTITUTION:When it is defined that the temp. characteristics of the 1H delay line 6 is -alphappm/ deg.C and that of the 1/2H delay line 10 is -betappm/ deg.C, the sum of the temp. characteristics in an odd field using both the 1H and 1/2H delay lines 6, 10 is -(alpha/2+beta)ppm/ deg.C. Since only the delay line 6 is used in an even field, the sum of the temp. characteristics is -alphappm/ deg.C. Since the gain of an amplifier in a temp. compensating circuit 9 is changed in accordance with its peripheral temperature, a difference between the temp. characteristics of the odd and even fields can be canceled by providing the circuit with (beta-alpha/2)ppm/ deg.C temp. coefficient. Since temp. compensation can be attained only by one temp. compensating circuit, the number of parts, cost, etc., can be reduced.

Title: Overcurrent protection network
Inventor: INAGAWA YUICHI
IPC: H02H9/02
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To provide an overcurrent protection network which is capable of improving temperature characteristic and removing a current detecting resistor from an output path, without depending on input or output voltage. SOLUTION: When an output current IO reaches a peak current, the current flowing in a current-detecting resistor RA increases, causing VA to rise. When VA has become greater than REF1, a current begins to flow in a transistor Q15. This makes current to flow in transistors Q16, Q17, causes the base current of a transistor Q12 to decrease, and curbes voltage drop in a resistor Rd4, which in turn causes the base voltage of an output transistor Q11 to rise. As a result, an output voltage VO begins to decrease and VB also declines. If a base voltage of VREF2+VB of a transistor Q18 becomes less than VREF1, Q18 starts to operate. This turns off Q15, and the output current is reduced by the current flowing in Q18.

Title: Resistive ribbon for heat transfer, printer using said ribbon and manufacture of said ribbon
Inventor: ARI AFUZARIIAIDAKANI
IPC: B41M5/382
Filed: 1988-10-20
Abstract: PURPOSE: To enable an image of high resolution to be printed by providing a dual resistive layer formed of a first resistive layer with low electric resistivity and a second resistive layer with high electric resistivity. CONSTITUTION: The ribbon 10 is formed of a dual resistive layer 16, a conductive metal layer 14 and a heat-softening ink layer 12, and the dual resistive layer 16 is formed of a low resistivity layer 4 and a high resistivity layer 6. Current runs into the dual resistive layer 16 by energizing a needle electrode 18 for printing in a specified pattern, and further, runs to a grounding electrode 20 after passing through the conductive metal layer 14. Thus a significantly resistive heat is generated in the small area of the resistive layer 16 to soften the area 30 of the ink layer 12 corresponding to a printing electrode, and this softened ink is transferred to a receiving medium such as paper.  Consequently, the resistive layer around the needle electrode 18 is not heated by forming a high electric current path running through the conductive metal layer 14 from the low resistivity layer 4 and therefore, the resolution is not deteriorated and an ink dot which is almost of the same size as the needle electrode 18 can be transferred to perform high resolution printing.

Title: Determining method for etching end point
Inventor: SHIROSAKI TOMOHIDE
IPC: G03F7/26
Filed: 1989-10-09
Abstract: PURPOSE:To accurately determine the end point of an etching without reception of influence of a variation in an emitting light intensity due to a loading effect by differentiating a voltage signal responsive to a light intensity, and determining the end point of the etching based on the fact that the differentiated value becomes a predetermined range larger than a predetermined value after it becomes smaller than the set value smaller than a predetermined value. CONSTITUTION:When a plasma discharge is generated in a vacuum chamber 1 in which an etching is started, an emitting light intensity of the discharge initially becomes high. In this case, a photoelectric converter 5 receives a light having a wavelength passed through a spectral filter 4 of the emitting light of the discharge and outputs a voltage signal (v) responsive to the intensity. A microcomputer 7 differentiates a stored digital voltage signal V, and stores the differentiated value (dV/dt). Simultaneously, whether dead time DT is elapsed from the start of the etching or not is judged, and then whether the value (dV/dt) of the signal V becomes lower than a threshold value (a) or less or not is judged. Thereafter, when the value (dV/dt) becomes zero, it is determined as an etching end point, and an etching end signal is output. As a result, the etching is finished.
