Title: Liquid crystal display
Inventor: YAMAMOTO TAKASHI
IPC: G09G3/36
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display capable of carefully saving of power consumption by stopping the drive while keeping a display state as it is, providing an operation mode for putting off a back light and a switch for turning on/off the back light independent of a panel controller. SOLUTION: In a power consumption mode 1, when an idle state is continued for a fixed time more and no input is given by an operator, the mode is shifted to a power consumption mode 2, a back light 212 is put off in addition to the power consumption mode 1, the moreover reduction of power consumption is attained but the last display contents at the time of driving is continuously maintained. Consequently, by putting on the back light by turning on a BL switch 107 by the operator, the displayed contents of the liquid crystal display is temporarily confirmed. Since the BL switch 107 directly turns on/off the power source of a lighting circuit 216, the starting of a CPU 201 in the mode of power consumption is not necessary.

Title: Aligner and production of plasma display using the same
Inventor: IWANAGA KEIJI
IPC: H01J11/36
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To improve pattern shape and resolution by making relation between the illuminance of a g-line and that of an i-line out of ultraviolet rays reaching an exposure surface satisfy a specified conditional expression. SOLUTION: The relation between the illuminance Lg(mW/cm2) of the g-line(light whose wavelength is 436 nm) and the illuminance Li(mW/cm2) of the i-line(light whose wavelength is 436 nm) out of the ultraviolet rays reaching the exposure surface If satisfies the conditional expression: Lg×0.4>Li. When the relation being Lg×0.4>Li holds, the coating film of photosensitive paste is sufficiently cured to its lower layer. Out of such a range, the coating film is not sufficiently cured to the lower layer. When exposure is increased further in order to sufficiently cure the coating film to the lower layer, photoset progresses on a surface layer by the i-line, so that the head of the pattern gets much larger than a designed value. It is desirable to use a high-output lamp whose output is 5 to 30 kW as an ultraviolet lamp such as an extra-high pressure mercury lamp 1a.  By using the high-output lamp, the exposure time is shortened.

Title: Flip flop circuit
Inventor: HANAWA MAKOTO
IPC: H03K3/356
Filed: 1990-09-21
Abstract: PURPOSE:To prevent the destruction of data to be held by means of subsequent input data by setting the threshold voltage of a path transistor transferring input data to a data holding circuit to be higher than that of other N-channel MOSFET. CONSTITUTION:When N-channel MOSFET is used for the path transistor, an output signal Vout goes to Vout=Vgs-Vth assuming a gate voltage is Vgs and the threshold is Vth. Then on output voltage is dropped. Thus, the threshold voltage of N-channel MOSFET 301 is set higher (Vtnh>Vth). Consequently, the drop of the output voltage furthermore is increased. Since the threshold voltage of N-channel MOSFET for data output T305 is set higher in the same manner as N-channel MOSFET for data writing T301, N-channel MOSFET for data output T305 whose output is to be prohibited goes to an interrupted state earlier. Thus, the collision time of output data is shortened and accurate output data can be decided at high speed.

Title: Recording/reproducing device
Inventor: MORIMOTO TAKESHI
IPC: H04N5/92
Filed: 1983-12-27
Abstract: PURPOSE:To reduce remaining jitters and color dislocation by generating a writing clock by a horizontal synchronizing signal and a burst signal overlapped at every time-base-compression multiplex signal. CONSTITUTION:A burst signal of single frequency is overlapped at a front porth in a horizontal blanking period of plural video signals. Image signals applied with time-base-compression supplied to an input terminal 21 of a time-base corrector 15' at the time of reproduction are taken out at their horizontal synchronizing signals by a horizontal signal separation circuit 22, and a frequency fM of a master clock is generated in a PLL27. On the other hand, only burst information of said video signals is taken out by a burst gate BG37. An 1/i divider 36 is a circuit to divide the frequency fM of the master clock into 1/4 so as to write and generate the frequency fc of a writing clock; and by resetting signals by burst information, the rise of a burst signal and that of a writing clock of the output of the divider 36 are set closest in phase. Moreover, a phase comparator PC38 detects their fine dislocation in phase and coincides a writing clock with that of a burst from a phase shift circuit 39 in phase.

Title: Vibration suppressing mount
Inventor: TODOME KAZUHIDE
IPC: B64G1/66
Filed: 1991-09-30
Abstract: PURPOSE:To reduce the vibration of a mount for resonance by attaching a viscoelastic member on a mount member for installing the equipment. CONSTITUTION:The experiment equipment 1 is fixed on the frame 2 of a rack for mounting the equipment by a vibration preventing mount 3. In this case, a viscoelastic member 4 is nipped by the mount member 5 of the mount 3 and a restraining plate 6. The bending deformation of the mount member 5 which is generated by being applied with the fine vibrational external turbulence generates an extension/contraction strain on the attached surface with the mount member 5 consisting of the viscoelastic member 4. On the other surface of the viscoelastic member 4, the extension/contraction is restrained by the restraining plate 6, and a shear strain is generated on the viscoelastic member 4. Accordingly, a high structural damping for suppressing the vibration by the internal friction of the viscoelastic member can be obtained, and the vibration is reduced.

Title: Signal processing circuit for digital audio signal
Inventor: ISHII HIDEHIRO
IPC: H03G3/02
Filed: 1988-10-05
Abstract: PURPOSE:To prevent production of noise during fade-in and fade-out operation by varying each sample value of a digital audio signal gradually by a prescribed value each, generating a high frequency eliminating command signal and converting an analog audio signal into a digital data corresponding to a component of an audio signal at a prescribed frequency or below. CONSTITUTION:An output data of a digital filter 3 is converted into a digital data corresponding to a component of an audio signal below a frequency fco represented by an output data of the digital filter 3. Moreover, a changeover switch 11 outputs an output data selectively of the digital filter 3 in the absence of a high frequency elimination command signal outputted from a microcomputer 2 and outputs selectively an output data of a digital filter 12 in the presence of the high frequency elimination command signal. Then an output of the changeover switch as an output data of a data conversion means 10 is fed to a D/A conversion circuit 4. Thus, noise production during fadein and fade-out operation is prevented.
