Title: Laser device
Inventor: FUJINAGA SEI
IPC: H01S5/068
Filed: 1990-03-30
Abstract: PURPOSE:To monitor accurate value of a current flowing to a laser diode by using a current value flowing to a resistor connected in parallel with the diode not as a fixed value but as a detected current value. CONSTITUTION:A DC current Idc is steadily input as a bias current to a laser output unit 11 from a laser driving DC output circuit 16 of an oscillation current supply unit 14. A predetermined AC current Iac is input to the unit 11 corresponding to a digital signal to be output as light data from a laser driving AC output circuit 17. A laser diode 12 of the unit 11 outputs, when the current Iac is input, a laser. The diode 12 is so monitored that a DC value flowing to the diode 12 does not exceed a predetermined value. A current of an accurate value flowing to the diode 12 is obtained by subtracting a resistor current 27 from an oscillation current 19 by a subtracter 21, and output as a monitoring current 28.

Title: Liquid crystal light valve
Inventor: WATANABE YOSHIO
IPC: G02F1/1333
Filed: 1991-04-16
Abstract: PURPOSE:To simplify the element constitution of the optical write type liquid crystal light valve and to realize a high-definition display. CONSTITUTION:The light valve consists basically of a display body layer and a photoconductor layer 8 sandwiched between two opposite substrates 1. The display body layer is formed of a layer wherein liquid crystal 5 and macromolecules 4 are mutually dispersed and oriented in one direction by an orienting film 3. The display body layer and photoconductor layer can be installed closely to each other, so the diffusion of carriers can be minimized and the high-definition display can be made. Although a conventional liquid crystal light valve needs to have two optical systems for write light and read light, a display device whose write light functions as a read light source can be constituted.

Title: Damage defector of handrail for passenger conveyor
Inventor: HINO HITOSHI
IPC: G01M99/00
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To accurately detect the damage of, for example, the disconnection of a steel cord in a handrail and to prevent it from being overlooked by reporting the presence or absence of an abnormal part by either sound or light or by combining them when the abnormal part is detected. SOLUTION: When an escalator 1 is operated and a flaw detector 2 of the handrail is placed at a handrail 1a, an analog signal is outputted from the detector. The signal is converted to digital data by an A/D converter 4 via an input cable 3, is taken into a notebook personal computer 6 via a communication line 5, and is displayed on a drawing. A displayed signal waveform is recorded by regarding a signal exceeding an arbitrary voltage (for example, 400 mV) as a joint signal. Also, a signal that is less than an arbitrary voltage (for example, 20 mV) is regarded as a noise signal and is used as invalid data. When the voltage is equal to or more than an arbitrary voltage (20 m V), it is recognized as a failure. When the failure is detected, an analog meter reads data, a buzzer rings, and a light-emitting diode lights up.

Title: Super low-power interatimic power microscope
Inventor: BUAAJIRU BII ERINGUSU
IPC: G01B21/30
Filed: 1993-04-12
Abstract: PURPOSE: To form image with high sensitivity and resolution by vibrating the tip of an probe at specified frequencies and amplitudes to remove the shearing force of a probe to a sample, and to prevent the sticking of the tip of the probe. CONSTITUTION: The tip of a probe is vibrated at the resonance frequency of a cantilever or its harmonic or its approximate value and made to collide against the surface of a sample. While the tip of the probe comes into contact with the surface of the sample, the lateral movement of the tip is restrained to be minimum for excluding scratching or tearing up from the sample. In addition, the amplitude of the probe is set up more than 10nm, generally the level of 100-200nm, to make the energy of the cantilever sufficiently large for preventing the tip of the probe from adhering to the surface. In addition, since the interaction of collision between the sample and the tip of the probe is strong and the tip is brought into contact with the surface, high sensitivity and high resolving power can be obtained.
