Title: Clock signal generation circuit
Inventor: YOMO MICHIHARU
IPC: G06F1/10
Filed: 1990-01-23
Abstract: PURPOSE:To reduce timing difference between the nodes of a load circuit by dispersing the output stages of a clock signal generation circuit on wires in the load circuit. CONSTITUTION:When a reference clock is inputted to the input node N1 of a timing generation circuit block 1, the potential of the node N2 rises after contant delay time. The signal is inputted to the node N3 of the load circuit 4 via a load driving circuit block 2, and also, it is inputted to a second load driving circuit block 2 via a ladder circuit consisting of resistors RL and capacitors CL', and is connected to the node N7 of the load circuit 4. Since delay time at the ladder circuit can be neglected, the waveform of the node N3 is equalized to that of the node N7, and the node N5 positioned in the center of the load circuit 4 is provided with the maximum delay. However, its delay quantity is less than that of the node N7 in the case where no ladder circuit and second load driving circuit exist.

Title: Thin film magnetooptic element
Inventor: ITOU MASATAKA
IPC: G02F1/09
Filed: 1983-01-31
Abstract: PURPOSE:To permit phase matching of a thin film magnetooptic element by setting the thickness and width of a waveguide at certain specified values so that the propagation constants of a TE wave and a TM wave are made coincident. CONSTITUTION:The thickness t1 of a waveguide is so set that the magnitude of the propagation phase constant with respect to an optical waveguide mode (TE wave) having an electric field component oscillating in the direction horizontal to a base plate attains the value smaller than the magnitude of an optical waveguide mode (TM wave) having the electrical field component oscillating in the direction perpendicular to said plate, and further the width W of the waveguide is so determined that the propagation phase constants of the TE wave and the TM wave coincide with each other. If the lattice constant of the waveguide layer adjusted by substituting a part of the yttrium element of YIG with the other rare earth ion having a large ion radius is larger than the lattice constant of the base plate, the thickness and width of the waveguide are further adequately set. The thin film magnetooptic element that permits phase matching is thus realized.

Title: Lens forming mold
Inventor: HIROTA SHINICHIRO
IPC: C03B11/08
Filed: 1990-01-24
Abstract: PURPOSE:To facilitate release of a lens from a mold by forming plural recesses in the forming surface of at least one die of the opposed dies outside the effective diameter of the lens. CONSTITUTION:The forming mold 10 is used for forming a concave lens, and its forming surface 11 is made convex. Plural intermediate recesses 12 are formed in the forming surface 11 outside the etfective diameter r of the lens. The recesses 12 are arranged at regular intervals along the cirnmference of the diameter K. Glass is introduced into the recess 12 when a lens is formed, and the protruding part of glass overflows from the recess 12 by the difference in contraction from the mold when the lens is contracted. Accordingly, a gap is formed between the forming surface 11 of the mold 10 and the surface of glass to be formed between the recesses 12 and 12. Consequently, since air is introduced inside (mold or lens center side) from the gap, the lens is easily released from the mold 10.

Title: Multiplex system for digital voice signal
Inventor: TOZAKI AKIHIRO
IPC: H04J3/00
Filed: 1987-01-23
Abstract: PURPOSE:To extend an error correction capability particularly against burst errors by multiplexing digital voice signals in two channels at positions distant from a video signal in terms of time, and correcting a correction-unable error by using the data in each other channel in case the error occurs in a voice data at the time of reproducing. CONSTITUTION:An L-channel data and an R-channel data are time-base-compressed by time base compression circuits 5L, 5R so that the former can be multiplexed in the vertical blanking part in the first field of a video signal and the latter in the same part of the second field of the same signal, then multiplexed with each other by a multiplex circuit 6. Thereafter, the resulting signal is multiplexed with a video signal by a multiplex circuit 9. In case the correlation between the two channels is high, a switch 10 is turned on, an interpolation control code generation circuit 11 generates an identification information representing the presence of a correlation, which is multiplexed in the video signal together with a digital voice signal. At the time of reproducing, if a correction-unable error occurs in a data of one channel, the correction of it is executed based on the data of the other channel. Also, this data correction between the two channels is executed only when an identification information is present.

Filed: 1982-02-01
Abstract: PURPOSE:To make the power consumption at incoming call and howler state equal to that at communication and calling state, by stopping power supply to a CODEC and a call circuit at incoming call and howler state, and supplying a part of the power to a calling circuit, in a digital telephone set. CONSTITUTION:A monitor circuit 24 activates the power supply of power supply communication circuits 21, 23 other than the calling and howler state, stops the power supply to a power supply control circuit 22, a communication circuit 12 and a CODEC 10 are activated and a call circuit 11 is stopped. Since a calling signal is transmitted with the presence of an incoming call, this is interpreted at a signal control section 9, an instruction is given to the monitor circuit 24 and the circuit 11 to invert the operation of the control circuits 21 23. Thus, a call tone rings in the circuit 11 according to a tone indication signal from the circuit 9. When a called party responds, an off-hook signal is given from the circuit 9 to the circuit 24, resulting that the control circuit 21 23 are restored to the original state. If on-hooking is not done after the call, the power supply control for howler detection is done.
