Patent JP-H03141675-A (JP)
Title: Semiconductor memory
Inventor: YOSHIDA MASANOBU
IPC: H01L29/788
Filed: 1989-10-26
Abstract: PURPOSE:To provide high speed operation without signal delay by extending branches from word lines formed along lateral arrays of memory cell transistors and using part of each branch as a control gate. CONSTITUTION:Thick word lines 32 are formed along lateral arrays of memory cell transistors. The word lines 32 have branches 33, which extend toward memory cell transistors and form control gates 22. Therefore, it is only necessary to make the branches 33 thinner for the memory cell transistor of smaller gate length. In other words, the word line itself does not have to be thinner, and it can maintain low resistance. Floating gates 18 are under the branches 33, and no steps exist under the word lines 32. Thus, the word lines have low resistance enough for high speed operation.

Title: Voice switching system
Inventor: KENMOKU ETSUO
IPC: H04B1/74
Filed: 1989-10-27
Abstract: PURPOSE:To continue the lesson without the intermission of voice of a lecture by monitoring a reception signal from a satellite communication line, switching a voice signal automatically into a backup voice signal from a ground line when a fault takes place and restoring the voice when the fault is recovered. CONSTITUTION:When the reception of a picture signal (e) and a decoded voice signal (g) is disabled due to a fault of a satellite communication line, a picture decoder 1 always monitors the reception signal (a) and outputs a line fault signal (c) to a switch control section 2. The switch control section 2 processes the line fault signal (c) with a frame clock (h) to send a selection signal (d) to a changeover device 3, which selects the backup voice signal (b) from the decoded voice signal (g) automatically and the backup voice signal (b) is outputted to an output terminal (f). In this case, since the satellite communication line is faulty, no picture signal (e) is outputted only the voice signal is outputted. Thus, changeover is implemented quickly and surely without manual operation.

Patent JP-S63133706-A (JP)
Title: Balanced modulator
Inventor: SATO TADANOBU
IPC: H03C1/54
Filed: 1986-11-25
Abstract: PURPOSE:To automatically reduce a carrier leak by forming a feedback loop giving a DC offset to the input of a modulation wave in accordance with the amplitude of an output during the silence signal period of an output to be modulated. CONSTITUTION:A sampling pulse SP is inputted to an amplitude detector 1. Only during a period when the sampling pulse SP is H, a switch SW is closed to operate a circuit. In that initial state, the base potential of a transistor Q9, is higher than a reference voltage V5, and a great collector current flows in the transistor Q9. A current is supplied to the base of a transistor Q2 through a current mirror consisting of transistors Q11 and Q12, and the base potential of the transistor Q2 rises. This change occurs in the direction in which a constant voltage V4 eliminates the DC offset, whereby the base potential of the transistor Q9 falls. By forming such a feedback loop, the circuit is stabilized in a state where a slight carrier leak regulated by the reference voltage V5 happens.

Title: Microcomputer-applied device with back-up function for check of input circuit
Inventor: TONOU HIROTOSHI
IPC: G06F13/00
Filed: 1984-12-27
Abstract: PURPOSE:To shorten the check time by comparing an abnormal state with another input supplied via an input circuit to deliver an output according to the result of said comparison when a program needed for control of an applied device is added to a microcomputer for detection of the abnormal state. CONSTITUTION:A control system of a microcomputer applied device containing a back-up function for check of an input circuit is provided with a 1-chip microcomputer 10 containing a ROM and a RAM, an input circuit 11 which receives the binary signal, an A/D converter 12 for analog signals and an output circuit 13 which delivers digital signals. When the computer 10 is switched to a check mode, an analog signal A is set at an H level that is normally unconceivable.

Title: Distance sensor
Inventor: TANAKA TOSHIHIRO
IPC: G01S17/10
Filed: 1995-10-30
Abstract: PURPOSE: To obtain a distance sensor by which a distance measuring error is suppressed surely without sharply changing an existing constitution by a method wherein the waveform of pulses is differentiated under a transmission characteristic that a pulse width at an output end does not exceed a predetermined pulse width. CONSTITUTION: A processor 51 regards the middle point between the rise timing and the fall timing of an electric signal as the receiving timing of reflected waves from a target, it changes over an instruction to a comparator 60 at every transmitting cycle, and it performs an arithmetic operation so as to obtain the relative distance of the target. In a state that the waveform to be outputted from an amplifier 59 is clipped or that the fall timing is delayed sharply as compared with the rise timing, a high-pass filter 31 as a differentiating means suppresses a frequency component in a region which is lower than the main frequency component of the electric signal. The output of the high-pass filter 31 comprises a waveform whose amplitude and pulse width are reduced, the higher a cutoff frequency is.  Consequently, even when the pulse width of a saturated input signal becomes wider, an output whose pulse width is constant can be obtained.

Filed: 1992-10-21
Abstract: PURPOSE:To increase the cooling effect for a bearing section by installing an air guide inside a bracket, by eliminating an upper flange and by providing a ventilation hole in a lower flange. CONSTITUTION:This equipment is different from the conventional one in that there is no upper flange, a ventilation hole 9 is provided on an upper flange 7B and air guides 8A, 8B are provided inside the brackets 6A, 6B respectively. In this structure, the radiation for a bearing section 5 shown by thick line arrows is the same as in the conventional equipment, but cool air comes in through the ventilation hole 9 as shown by thin line arrows and this cool air is guided to the air guides 8A, 8B and then it flows outside through a space between the upper air guide 8A and the bearing section 5 (where an upper bracket is eliminated). By this, the heat radiation is active on the surface of the bearing section 5 that faces a rotor iron core 2 and thereby the cooling effect of the bearing section 5 is increased.
