Title: Crystal oscillator watch provided with analog time display portion with manual time change device
Inventor: URUSU GIJIEERU
IPC: G04B19/22
Filed: 1978-12-27
Abstract: In the quartz watch according to the invention all the time displaying hands (of the hours, the minutes and, possibly, the seconds) are kinematically permanently connected to each other, so that their relative positions are precisely fixed, whatever manipulations are made by the user. As shown, the rotor 7 of a stepping motor drives seconds wheel 16 driving a wheel 20 (on the minutes hand shaft 23) driving hour wheel 28. A clutch may be provided between the rotor and the seconds wheel. Pulling out a stem 64 to a hand setting position energises automatic hand setting control circuitry having a detector sensitive to the manually controlled displacements of the hands and a counting device for finishing off these displacements and for memorizing the time impulses during the manual correction. The arrangement ensures automatic setting of the hands in the exact time indicating positions, thus permitting a user who travels from one time zone to another to make rapidly the necessary manual adjustment without prejudice to the previous precision of the time indication. Accurate setting of a seconds hand may also be provided. <IMAGE>

Filed: 1994-06-22
Abstract: PURPOSE:To allow the day-of-the week of a schedule board to be altered by bending a belt member in an arc state at the end of a rail frame. CONSTITUTION:When a first day becomes, for example, Saturday due to the change of a month from the state that a first day is Wednesday, a finger is engaged with a slide plate 4 to move the plate 4 toward the first day. Then, the belt member 5 of a head side is wound on a pulley 11 to be rotated to be moved to an inner space 6d, the day of the week of the member 5 of a room side is introduced into a rail main body 6a, and 'Wednesday' 'Monday' of six days are continuously displayed. If the first day of the month is Sunday, the plate 4 is fully slid to a tail side. Then, the days of the week of the member 5 of the head side are all introduced to the body 6a so that the head becomes 'Sunday', the member 5 of the tail side is wound on the pulley 11 to be moved to the inner space 6d. When the plate 4 is slid in a suitable direction in this manner, it can completely deal with all the cases.

Title: Flash device
Inventor: OOMORI KOUICHI
IPC: G03B7/16
Filed: 1983-09-07
Abstract: PURPOSE:To prevent the change of aperture of a photographic lens and the change of display of an interlocking range at each time of light pre-emission, by providing a control means to make the quantity of emitted light of light pre-emission after a display means displays that flash light emission possible. CONSTITUTION:When a reflected light from an object is made incident on a photo transistor TR23, charging to capacitors 57 and 60 is started. When the charging level rises to a prescribed level and a comparator 73 is inverted to the high level, the output of an AND gate 81 goes to high-level, and a thyristor 19 is triggered, and the main light emission is interrupted by the normal method to perform flash photographing. Even if the charge quantity of a main capacitor 9 is not sufficient after lighting of an LED53, strobe photographing with a correct exposure is performed similarly. Since the charge quantity of an auxiliary capacitor 6 is made constant by a Zener diode 143, the quantity of emitted light for light pre-emission is made constant, and the quantity of emitted light of light pre-emission is changed, so that the aperture value of the photographic lens is not changed or the display indicating whether the object is within an interlocking distance range or not is not changed in accordance with the variance of the charging level of the main capacitor.

Title: Noise measurement of video signal
Inventor: KAMIJO KOJI
IPC: G01R29/26
Filed: 1986-07-15
Abstract: PURPOSE:To measure a noise spectrum of a video signal, by performing a sweeping of a gray level video signal with an intermittent sweep type spectrum analyzer only during the period of a synchronous signal thereof. CONSTITUTION:A gray level video signal generator 1 generates a gray level video signal having such a synchronous signal as to coincide among external synchronous signals from a synchronous signal generator 3. The signal is inputted into a VTR2 to be measured as recording signal to obtain a reproduction signal. The reproduction signal thus obtained from the VTR2 is detected as DC current with a DET16 of an intermittent sweep type spectrum analyzer 12 and deflects the vertical axis of a CRT20 after the averaging of random noises through a video filter 17. On the other hand, a lamp generator 19 holds an output voltage with a holding circuit 19a when an external sweep signal is at an Lo level. Thus, the analyzer 12 analyzes the frequency only when the sweep signal is at a Hi level. When the gray level video signal is measured, an optimum sweep control signal is created with a sweep signal generator 4.

Title: Driving method for fluorescent display device
Inventor: HARA ZENICHIRO
IPC: H01J31/15
Filed: 1990-06-21
Abstract: PURPOSE:To suppress an erroneous display, what is called a leakage light emission generated in connection with leakage of a thermion by driving two kinds of control electrodes connected in common in the line direction or the row direction for controlling a flow of the thermion by different potential. CONSTITUTION:Different voltages are applied to a scanning electrode 3 and data electrode 4, and to put it concretely, by making the potential of the scanning electrode 3 side small, both control electrodes are driven. That is, a leakage light emission at the time of 'black' display is caused by a fact that the vicinity of a cathode 2 which originally becomes a cut-off state by negative potential of the data electrode 4 becomes an insufficient out-off state since the potential of the scanning electrode 3 is high, a small thermion is attracted to the potential of the scanning electrode 3, and it passes through an opening part of a shielding electrode and comes into collision with a phosphor. Therefore, the potential of the scanning electrode 3 side is made lower than the potential of the data electrode 4 side. In such a way, at the time of 'black' display, surplus potential of the scanning electrode 3 for obstructing the cut-off state by the potential of the data electrode 4 is reduced, a satisfactory cut-off state is obtained, and the leakage light emission is suppressed.
