Title: Optical range finder
Inventor: TAMAI SEIICHIROU
IPC: G01C3/06
Filed: 1983-04-30
Abstract: PURPOSE:To minimize obscuration of a spot light image at the photoelectric sensor and increase accuracy by a device wherein the photoelectric sensor is arranged such that an angle made by the photoelectric sensor of light receiving means crossing the light receiving optical axis substantially equals to an angle made by the light projecting optical axis of light projecting means crossing the light receiving optical axis. CONSTITUTION:Light projecting means to project a spot light and light receiving means to detect a spot light image projected on the measured objective from the light projecting means are provided. A photoelectric sensor 5' is arranged such that an angle theta made by a light projecting optical axis 7 crossing a light receiving optical axis 8 becomes substantially equal to an angle theta made by the photoelectric sensor 5' crossing the light receiving axis 8. With this arrangement, the spot light image is focused substantially on the photoelectric sensor 5' as an image A'', B'' with no obscuration. Thus, when using a PSD or CCD element as the photoelectric sensor, sensitivity and accuracy of positional detection can be improved drastically.

Title: Method and apparatus for measuring time
Inventor: KATAOKA TOSHIHISA
IPC: G04F13/02
Filed: 1989-03-29
Abstract: PURPOSE:To measure time with high resolutions in a short time by a method wherein a second CKP with a frequency thereof higher than a first clock pulse (CKP) is divided in frequency and transmitted every A/(B-A)th to measure A/(B-A) times. CONSTITUTION:When a first CKPa and a second CKPb rise simultaneously and a transmission pulse (c) is outputted from a frequency divider 12, a light pulse is outputted from an LED 14 while the CKPa is counted 21 by an output (e) of an FF circuit 7 and an output (f) of a second counter 20. Then, when the light pulse is received, the output (e) of the circuit 17 gets a first AND gate 18 closed by a signal (d) from a light receiving circuit 16 to block the passage of the CKPa. Then, an output (c) is outputted corresponding to 1,000th of the CKPb divided 12 in frequency to 1/1,000 to repeat a counting of the CKPa. When the measurement 20 is performed 1,000 times, a second AND gate 19 is closed. Here, for example, when the CKPa is set at 100MHz and the CKPb at 100.1MHz, resolutions per measurement for 100MHz are 10nsec. An average of 1,000 measurements results high resolutions of 9.99sec.

Title: Self stereoscopic vision display with plural sets of flashing line and light bulb
Inventor: JIEESHI BII AIHIENRAUPU
IPC: G02B30/27
Filed: 1990-03-28
Abstract: PURPOSE: To display a three-dimensional image by alternately and continuously flickering plural pairs of light emitting rays in an illumination pannel and displaying a group with different images whenever the different group of a light emitting part flickers in an optical valve having individual image element on a surface. CONSTITUTION: Optical valve array 4 provided in parallel in front of the illumination pannel 1 having plural groups of vertical light emitting rays 2 and 3 forms the image by changing the transmissivity of the respective image elements 5 by transmissivity. Then, the groups 2 and 3 of the respective rays extremely quickly, alternately and continuously flickers so that faulse impression that the light emitting rays are 'jumping' forwards and backwards between the positions 2 and 3 occurs and some rays seems to be continuously flickering. The optical valve 4 is synchronized with the illumination pannel 1.  When the ray 2 is flickering, for example, the part of the left eye image of a scene in a certain string 9 which is at the front and left side of the ray 2 is displayed and the right eye image of the scene is displayed in the string 9 which is at the front and right side of the ray 2. Therefore, an observer views a stereoscopic viewing image by depth false impression. Thus, the three- dimensional image is formed by a thin, small and light display device.

Title: Key device
Inventor: HIRAMOTO YUKIO
IPC: B60R25/04
Filed: 1993-03-12
Abstract: PURPOSE:To reduce the time for judgement of the key collation by changing the frequency from a signal generating means, detecting the time from the start of the change to the detection the resonance frequency, and driving the engine when the detecting time agrees with the set time. CONSTITUTION:Rotor coils 24, 26 are coiled around a core 22 arranged on the circumference of a key inserting hole 12. A resonance frequency detecting circuit 39 detects the generation of the resonance by the voltage drop of a resistor 28 connected to the rotor coils 24, 26, and supplies the stop signal to a timer circuit 50. The timer circuit 50 inputs the signal of the started oscillation to be supplied from a microcomputer 52 to a variable frequency oscillator 30 as the start signal, and starts the counting of the clock signal from a clock signal generating circuit 41. This counting is maintained until the stop signal is received, and this counting signal is compared with the reference signal which is set and stored in ROM, and when two signals agree with each other, the signal to permit the engine drive is outputted. That means, the resonance frequency is not read as a numerical value, and the time for judgement is reduced.
