Title: Electrophotographic camera
Inventor: TSUMASAWA HIROYUKI
IPC: H04N5/335
Filed: 1980-08-29
Abstract: PURPOSE:To judge the propriety of a picture immediately and to take a picture again immediately according to the result of the judgement, by displaying on a monitoring device a picture recorded in connection with the pushing operation of a release button. CONSTITUTION:The video signal of an object is inputted to a terminal 21. When a recording/reproduction changeover button is at a recording mode side, a terminal (a) is at a level L and no signal arrives from a reproducing head to hold a terminal (g) at the level L. At this time a gate G1 is open and the video signal is displayed ona monitor 3 by passing through the gate G1. When a release button 19 is pushed, a control terminal (b) is held at a level H and a disk motor control circuit 25 operates to open gates G4 and G5; after the notch part of a disk is detected, a terminal (i) is held at the level L and recording is started. As the disk turns once, the reproducing head reproduces a signal and the terminals (i) and (g) are held at the level H to cloe the gate G1 while the gates G2 and G5 are opened, thereby displaying the reproduced signal from a reproducing circuit 24 on the monitor.

Filed: 1985-06-05
Abstract: PURPOSE:To enhance sealing performance, by dividing a frame, which supports leads, into inner frames and an outer frame, providing coupling parts between the outer frame and the inner frames, and applying bending machining before sealing the leads. CONSTITUTION:A frame, which supports leads, comprises inner frames 71, 72, 73 and 74 and an outer frame 8. The outer frame 8 and the inner frames 71, 72, 73 and 74 are coupled with coupling parts 91, 92, 93 and 94. The inner frame 71 and a lead 101 are bent at an approximately right angle along a lead bending line (a). The coupling part 91, which is continued to the inner frame 71, crosses the bending line (a), with a gap R being provided with respect to the outer frame 8. Therefore, the bending of the leads 101 of the inner frame 71 is performed without relation to the outer frame 8. Under the bent state, an IC chip is mounted and packed in a square type package in accordance with IC packaging processes. The IC product is completed in this way. Thus the sealing property is enhanced.

Patent JP-S5549065-A (JP)
Title: Charging pulse transmission system
Inventor: OOTSUBO TOUKOU
IPC: H04M15/00
Filed: 1978-10-04
Abstract: PURPOSE:To prevent hearing of a called-subscriber's name from becoming hard due to a tone calling for a coin, by stopping transmission of the tone at the time of called-subscriber's response when one coin is put in. CONSTITUTION:Relays M and P in a public telephone operate when coins are inserted. Here, when a calling subscriber inserts only one coin, signal tone oscillator TG is unable to oscillate because contact (f) of relay F forms a short circuit, so that a tone calling for a coin is prevented from being sending to the calling subscriber. Consequently, the transmission of the tone at the time of called-subscriber's response when one coin is inserted is prevented and when not less than two coins are inserted, the fixed tone can be sent out. Therefore, the hearing of the subscriber's name at the time of the subscriber's response can be prevented from becoming hard due to the tone.

Title: Signal suppressing circuit
Inventor: IDE TATSUKI
IPC: H03G11/00
Filed: 1981-07-31
Abstract: PURPOSE:To attain the suppression of signal without using any diode characteristics, by obtaining the optional suppression characteristics even to an input signal of a low signal amplitude and at the same time simplifying the control of the suppression characteristics. CONSTITUTION:When the input signal S1 is set at O, the base potential of a transistor (TR) T2 is equal to the value obtained by subtracting the A-K voltage VD3 from the reference voltage V4 which is applied via a bias resistance R4. On the other hand, the base potential of a TRT1 is equal to the value obtained by subracting the A-K voltage VD4 from the voltage V4. The emitter potentials of the TRs T1 and T2 are set at the level which varied by the B-E potential respectively. Here the emitter potentials of the TRs T1 and T2 are equal to the voltage V4 if the accuracy is high for the diode and the transistor. Thus no current flows to a load resistance R4. With application of the signal S1, the base voltages of TRs T1 and T2 vary by a degree of S1. The emitter voltage also changes in the same way. Thus a current flows to a load resistance R5 by an amount equivalent to the change of said emitter voltage.

Title: Protecting circuit of dc-dc converter
Inventor: YAMANAKA SUSUMU
IPC: H02M3/155
Filed: 1986-05-27
Abstract: PURPOSE:To prevent breakage of a transistor due to shortcircuit of a load or the like, by a method wherein oscillation operation of an oscillator is stopped by inversion operation according to abnormal variation in output voltage of a control transistor. CONSTITUTION:Power source is supplied from a battery 1 to each circuit, and signal of H-level is applied to a control terminal 31 of an oscillator 2 through a capacitor 32, thereby the oscillator 2 starts oscillation operation. If voltage of a positive voltage output terminal 8 drops abnormally due to shortcircuit of a load 18 or the like, a control transistor 40 is inverted into non-conductive state and an oscillation control transistor 33 is inverted into non-conductive state. Thereby charging current flows through a capacitor 32, and if the charging operation is finished signal level of the control terminal 31 of the oscillator 2 goes to L-level. As a result, the oscillation operation of the oscillator 2 is stopped. If voltage of a negative voltage output terminal 10 rises abnormally due to shortcircuit of a load 27 or the like, the oscillation operation of the oscillator 2 is also stopped.

Thus, the original 6 is fed to the extent of an original stopping position just before a data read starting position in advance.

Title: Encoder using fourier image
Inventor: MOTOHASHI HIROAKI
IPC: G01D5/36
Filed: 1984-06-15
Abstract: PURPOSE:To obtain a highly accurate encoder characterized by high SN ratio by superposing a sub-scale to the position of a Fourier image of a main scale in an optical encoder having main and sub-scales. CONSTITUTION:Light is made incident on a collimater lens 2 by increasing the monochromatic property and emitting luminance of a light emitting element 1. Its parallel light is irradiated on the main scale 3 and the sub-scale 4 arranged in parallel and made incident on a photodetector 5. If the parallel interval D of both the scales 3, 4 is set up to nP<2>/lambda (n is a natural number, P is a pitch of the main scale and lambda is the full wavelength of the irradiated light), the Fourier image of the main scale 3 is formed on the sub-scale 4. If the parallel interval D is set up to an excessively large value, its SN ratio may be deteriorated, so that it is preferable to set up the number (n) to 3. Thus, the SN ratio is not reduced and it is unnecessary to form an optical system for the image formation of the main scale, so that the device can be simplified and reduced at its size.

Title: Digital flash printer
Inventor: TAKEDA YUUSUKE
IPC: G06K15/12
Filed: 1987-05-19
Abstract: PURPOSE:To permit gradation to be expressed easily by providing a timing generation circuit for delaying timing for light projection and allowing delay time to be changed in accordance with density level. CONSTITUTION:Delay time T2 is produced by a timing generation circuit 20, and after the delay time T2, a light source device 12 is caused to flash by a light source drive circuit 18 upon reception of light projection signal. In this way, a group of pixels of density level 2 are recorded. However, when this writing is performed, the area of pixels in the condition of light transmission through a liquid crystal array 10 is smaller than its normal size, so that pixels of middle density corresponding to the density level 1 are recorded as those of middle size or about. Finally information of density 1 is applied to a liquid crystal shutter array drive circuit 22 as an image signal. At the same time, a density level signal representing the density level 1 is added to the timing generation circuit 20. A liquid shutter array drive circuit 22 selects pixels having the density level 1 according to an image signal to be entered, and a drive signal is applied these pixels. Consequently, the distribution of light- transmitted pixels is formed on the liquid crystal shutter array in response to image information i. e., the arrangement of pixels of the density level 1.
