Title: Flash incorporating camera
Inventor: MIZUMO YOSHIYUKI
IPC: G03B17/02
Filed: 1989-05-23
Abstract: PURPOSE:To make a camera compact and to efficiently deal with noise by arranging a power source part and a booster circuit on the grip part of a main body, placing a trigger transformer and a flashing part close to each other and arranging a trigger circuit at another place away from these parts. CONSTITUTION:A dry battery 30 being a power source and a main capacitor 31 accounting for a large area of the booster circuit are housed in the grid part 11. Since a great current is supplied to other circuits in the booster part from the power source battery 30, they are arranged on the upper part of the grip part 11 closest to the battery 30. The trigger transformer 22 is housed in a space between the reflecting plate 34 of the flashing part 16 and a prism 14, and a substrate 33 mounting the trigger circuit is arranged between a prism 14 and an auxiliary unit 15. In such a way, constituents composing a flash system are decentralized and arranged by taking advantage of a space that has not been utilized before. Consequently, these constituents are incorporated without increasing the size of the camera main body, and noise is hardly produced.

IPC: H04Q3/42
Filed: 1979-10-09
Abstract: PURPOSE:To transmit the communication line polarity reversing pulse excellent in the noise interupting characteristics, by providing the DC communication current control means and performing the polarity inversion of communication line while no DC communication current flows. CONSTITUTION:When the start pulse ST indicating the transmission of charging pulse is incoming, a counter CNT is reset, a flip flop FF is set, and clock pulse is counted when the counter CNT is in the state of operation. The output of the count CNT is input to address terminals A0-A13 of ROM for address designation. Further, the output X1 controls the operation of a communication line polarity relay P, and inversion and restoration of communication line are made with the contactes P1, P2 of the communication line polarity relay P. Since the inversion and restoration of this polarity is made at the section when the current value is zero, noise can not almost be produced.

Title: Stereoscopic image reproducing device
Inventor: IWAMOTO SHIGEKI
IPC: H04N13/04
Filed: 1988-05-27
Abstract: PURPOSE:To identify a picture even without spectacles by watching a stereoscopic picture by a parallactic picture by eyes with and without a 2nd picture recognition polarized plate put thereupon. CONSTITUTION:The title device consists of the 1st picture display section 20a comprising a polarizing late 20a1 and a liquid crystal plate 20a2 displaying the 1st picture and of the 2nd picture display section comprising a polarizing plate 20b arranged to the front face of the 1st picture display section 20a and a liquid crystal plate 20c arranged to the front face of the polarizing plate 20b and displaying the 2nd picture. The display device 20 reproduces alternately the 1st and 2nd pictures, and since the display content of the 1st picture displayed on the 1st picture display section 20a is identified without a polarized glasses 30a put on, the 1st picture L1 can be watched by a left eye at a time t1. In this case, since the polarizing glasses 30a exists in the front of the right eye, the right eye is covered comparatively dark and since the left eye cannot watch the 2nd picture R1 because nothing exists in the front face when the end picture R1 reproduced next at a time t2 is watched by the right eye, and a light screen is watched simply. Succeedingly, it is repeated. Thus, the stereoscopic picture is watched by the parallactic picture by eyes with and without the polarizing glasses 30a.

Title: Television receiver
Inventor: SUGAWARA HIDEJI
IPC: H04B7/26
Filed: 1994-06-13
Abstract: PURPOSE:To reduce the effect by multi-path disturbance when television broadcast is received. CONSTITUTION:A correction circuit 14 is interposed in a transmission line from an antenna 2 to a video detection circuit 16. The correction circuit 14 includes filters F1-Fn to change the transmission characteristic of the transmission line and an HPF is adopted for the filters F1-Fn when all signal components of television broadcast are included in the upper side wave band and an LPF is adopted for the filters F1-Fn when all signal components of television broadcast are included in the lower side wave band. On the other hand, a reception state is detected from a state such as disturbance in a horizontal synchronizing signal from a synchronizing signal processing circuit 18, and when multi-path disturbance takes place, a reception state detection means 20 changes the resonance characteristic of the filters F1-Fn to emphasize signals in the vicinity of the video carrier frequencies. Thus, the deterioration in the received image due to multi-path disturbance causing synthesis of signals with opposite phases is suppressed. Furthermore, the occurrence of disturbance is detected over an image period.

Abstract: PURPOSE:To prevent the breaking of a DMOS field-effect transistor for power use due to the heat generation of the transistor by a method wherein the gate and cathode terminals of a thyristor are connected to the source terminal of the field-effect transistor. CONSTITUTION:With an anode terminal 21 of a thyristor 3 connected to a gate terminal 22 of a transistor 2, gate and cathode terminals 23 and 24 of the thyristor 3 are connected to a source terminal 25 of the transistor 2. When the temperature of the part of the transistor 2 rises, a breakover voltage of the thyristor 3 is abruptly reduced to become lower than a signal voltage to a gate of the transistor 2, the thyristor 3 is actuated and the gate and the source of the transistor 2 are shortcircuited. Because of this, the charge of the gate of the transistor 2 is discharged and a current stops flowing to the transistor. Thereby, the breaking of the field-effect transistor due to the heat generation of the transistor can be prevented.
