Title: Travelling lane deviation alarm
Inventor: KATO AKIRA
IPC: B60R21/00
Filed: 1992-11-30
Abstract: PURPOSE:To increase the warning force of a device which issues an alarm for the deviation of a vehicle from a travelling lane (white line) by monitoring the road states in the front and rear of the vehicle by a TV camera. CONSTITUTION:The white line on a road can be extracted by binarizing an image signal obtained from the TV camera, and the actuator 4 for vibration of a steering wheel part 3 is driven if no direction instruction signal for the vehicle is generated when the deviation of the vehicle from the white line is detected. Also, the actuator 4 directly excites a spoke part 21 in the steering wheel part 3. Furthermore, a horn driving circuit, an actuator driving circuit, and a control circuit are provided at an image processing device, and the control circuit drives only one of both driving circuits mutually.

Title: Convergence correction device
Inventor: OZEKI KOUSUKE
IPC: H04N9/28
Filed: 1990-11-27
Abstract: PURPOSE:To prevent the deterioration of adjusting adility and adjusting accuracy by providing a CPU with an initializing function initializing correction data generated by the CPU to the data so that the voltage of a static convergence correction signal from an A/D converter is set at 'O'. CONSTITUTION:A CPU2 is provided with the initializing function initializing the static convergence correction data generated by itself. That is, when dynamic convergence adjustment is executed, an adjuster shall preliminarily press an initialization setting button 10 on a remote controller 6. Then the CPU2 will actuate the initialization function to initialize the static convergence correction data generated. As a result, the voltage of the correction DC signal for the static convergence output from a D/A converter is set to zero. Thus, since the convergence adjustment can be performed by setting the direct current voltage generating in B at zero, the adjustment can be enabled within the capability of a dynamic convergence correction circuit.

Abstract: PURPOSE:To conduct an extension coll from an independent telephone set to another telephone set in the system by feeding 48V to the independent telephone set connected to a home telephone in parallel at closed-loop time and switching it to a low voltage at open-loop time. CONSTITUTION:When the independent telephone set 13 is in the closed loop state, 48V is fed to the independent telephone set 13 from an internal high- voltage power supply part 18 through a feeding part 16. At the time of the extension telephone call, a current detection part 17 detects the loop closure once the handset is put off the hook of the independent telephone sets 13. Consequently, a voltage switching part 20 switches the power supply from the internal high-voltage power supply part 18 to an internal low-voltage power supply part 19 to feed the low voltage to the independent telephone set 13 through the feeding part 16. Therefore the independent telephone set 13 calls another home telephone in the system by dialing to make the extension telephone call.

Filed: 1988-12-22
Abstract: PURPOSE:To stabilize an amorphous state, to erase at a high speed and to stabilize a recording state by forming a recording layer mainly of In10Sb3Te7. CONSTITUTION:A recording layer 2 for recording information and an organic material protective layer 3 are formed on a substrate 1 in an information recording medium. The recording layer 2 is formed mainly on In10Sb3Te7 intermetallic compound, and phase-changed reversibly between a crystal and an amorphous state by irradiating it with optical beams of different conditions. Since its crystallizing velocity is high, it initializing velocity and erasing velocity are fast. Since it contains 30atomic% or more of Te, its amorphous state is stable. The recording layer 2 can be formed by vacuum depositing, sputtering, etc. The protective layer 3 is so disposed as to prevent damage, dusts on the surface in case of handling the information recording medium, and composed of an ultraviolet ray curable resin, etc. The recording layer 2 is so composed as to be interposed between inorganic protective layers 4 and 5 to prevent the recording layer 2 from age-changing.

Title: Recording signal/reproduction signal processor and video recording and reproducing device
Inventor: MIYAZAKI YOSHIYUKI
IPC: H04N5/915
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a recording signal/reproduction signal processor and a video recording and reproducing device, in which only a camera signal which should not be outputted are appropriately masked. SOLUTION: Each camera signal, included in a time-division multiple camera signal reproduced by a VTR 22, is written into a prescribed area of a video memory 33, and then all camera signals are read from the video memory 33. When a reproduced discrimination code fulfills a first condition, a mask control circuit 42 releases a mask for the camera signal corresponding to the discrimination code. When the discrimination code fulfills a second condition, the mask control circuit 42 masks the camera signal corresponding to the discrimination code. On the other hand, when the discrimination code does not fulfill either condition, the present mask state is held. Thus, there is no occurrence of preventing a reguired camera signal from being masked by mistake, when only one camera signal is reproduced by still reproduction.

Title: Frequency generator
Inventor: UJO TATSUZO
IPC: G01P3/487
Filed: 1987-12-22
Abstract: PURPOSE:To enable the miniaturization of the title device and the reduction in weight thereof, by a method wherein an angle theta formed by lead wires in the radius direction which take out frequency signals from patterns on the front and back sides of a substrate is set to be (2n+1) times larger than an angle theta ' occupied by one pole in a disk-shaped magnet. CONSTITUTION:The number of magnetized poles is eight, while radial detection patterns 3A numbering twenty-four, i.e. three times the number of the poles, are disposed at equal intervals. Accordingly, an FG output (for frequency detec tion) of twelve pulses is obtained by one rotation of a magnet. The twenty-four patterns 3A are formed on the surface of a substrate 2. Herein a construction is made so that included angles between lead wires 14A and 14B on the front side of a pattern 3, between lead wires 24A and 24B on the back side thereof and between the lead wires 14B and 24A, i.e. opening angles theta, are maintained at 22.5 deg. corresponding to 1/2 of a magnetization angle theta '=360 deg./8=45 deg., respective ly. Although noise is generated in pattern positions of the lead wires 14A, 14B, 24A and 24B in a frequency generator constructed in this way, the noise at each position is canceled by that generated at the other position. Thus, the generator can be made small in size and light in weight.

Title: Liquid injecting recording apparatus
Inventor: NAKAGAWA YOSHIHIRO
IPC: B41J2/165
Filed: 1987-12-22
Abstract: PURPOSE:To obtain a simple and inexpensive construction capable of effecting a capping operation during a non-recording period by disposing in parallel to a power source switch a second switching means for cutting off a supply power source when a recording head is capped by means of a capping means and for making the supply power source when the capping means is removed from the recording head. CONSTITUTION:When a power source switch 1 is switched on, several types of voltages for controlling individual sections are supplied to a control section 7 via a stabilizing circuit 6, and in a case where a recording command is given to the control section 7 from an external section, a capping means 4 is caused to operate such as to be removed from a injecting surface 3A of a recording head with a second switching means 5 being kept in a ON state, the recording by the recording head 3 being thereby allowed to be effected. In other words, even when the power source switch 1 is switched off during a recording period, the second switching means 5 is allowed to remain in the ON state, and the recording operation can be continued by the action of the power source successively supplied as long as the capping means 4 is kept unactuated. The supply of power source is allowed to continue unless the recording operation is stopped by means of a key switch or a capping command is issued to activate a capping operation.
