Title: Semiconductor laser element
Inventor: NAKA HIROSHI
IPC: H01S5/00
Filed: 1988-07-20
Abstract: PURPOSE:To increase an optical output in individual temperature regions and to realize a high output by a method wherein an oscillation wavelength, a thickness and a composition for a light guide layer and an active layer are fixed and a proper value of the composition for the light guide layer is obtained. CONSTITUTION:At a 1.3mum band DFB laser, a diffraction grating pitch is set at about 200nm, and a thickness for a light guide layer 3 and an active layer 4 is set at 0.1mum. In the light guide layer 3 composed of InxGa1-xAsyP1-y, x is 0.847 and y is 0.328; a band gap for the light guide layer is set at 1.127eV. In addition, a band gap for the active layer 4 is set at 0.954eV. As a result, the I/L differential efficiency is increased by about 30% as compared with a conventional case. In addition, a probability of a single longitudinal mode oscillation is increased. Furthermore, since the band gap for the light guide layer is increased, a refractive index is lowered and a beam divergence angle of a laser beam is constricted by about 20%.

Title: Information identification sheet
Inventor: MATSUSHITA TOSHIHIKO
IPC: G11B7/24012
Filed: 1992-07-09
Abstract: PURPOSE:To obtain the information identification sheet excellent for preventing forgery. CONSTITUTION:The information identification sheet is formed by coating a surface size agent containing natural or synthetic pulp with a fluorescent pigment dyed or impregnated thereto onto a base and the pulp is in existence on the surface of the base coating layer so as to be a random pattern. The random pattern of the pulp on the base is read or recorded as visual information by irradiating an ultraviolet ray whose wavelength is 200-380nm onto the said information identification sheet and the information of the random pattern is repetitively identified.

Title: Measuring method of distance pulse
Inventor: TAKAMURA AKIO
IPC: G01P3/489
Filed: 1980-12-23
Abstract: PURPOSE:To measure speed precisely in the speed measurement to count up the number of speed pulses within a stated time range and calculate the speed by correcting an asynchronous error between time range pulses and distance pulses. CONSTITUTION:A speed pulse A is not usually synchronized with a time pulse B having a stated period T. For example, there exist asynchronous time Ti, Ti+1 between pulses (i), (i+1) and speed pulse just after these pulses. Therefore, the number of speed pulse N in period T generates the error of + or -1. The count value of clock pulses during the period of a gate signal E corredponding to asynchronous time is F. A storage command G stores the clock count value F as a storage value H. If asynchronous time DELTATi is subtracted and DELTATi+1 is added from and to the period T between (i) and (i+1), it will be regarded that A is synchronized with B. The operation is performed by using the storage value H. In addition, I', the count value of the number of speed pulses Ni during the period T, is regarded as a storage pulse J'. The speed is calculated from J' and corrected T.

Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To obtain a set arbitrary waveform in real time by turning on an illuminant with a current from a voltage-current converting amplifier. SOLUTION: A shot signal W having a pulse-like voltage waveform is outputted from a reference voltage generator 1 whenever a laser shot command is given.

Title: Apparatus for applying living body adhesive
Inventor: IKEDA KOJI
IPC: A61L24/00
Filed: 1987-07-21
Abstract: PURPOSE:To prevent the solidification of an adhesive in an apparatus due to the interruption of coating operation and the lowering in the bonding strength thereof during coating operation, by mounting two nozzles to the constricted ends of one set of syringe bodies in an easily deformable manner and using said nozzles by aligning the leading ends thereof by bundling both of them if necessary. CONSTITUTION:For example, a fibrinogen solution is received in one of one set of syringe bodies 1, 1 and the same amount of a thrombin solution is received in the other syringe body. Subsequently, one sets of nozzles 2, 2 are mounted to the tips 6, 7 of the syringe bodies 1, 1 and an integral operating means 4 is mounted to the flange parts of plungers 7, 7 to assemble a living body adhesive coating apparatus. Next, the needle tubes 9, 9 of the nozzles 2, 2 are deformed as shown by Fig. (a) or an auxiliary jig is used as shown by Fig. (b) or (c) to align the leading ends of the needle tubes 9, 9. Then, the integral operating means 4 is pushed by the thumb to simultaneously inject two solutions to a region to be coated. By this method, since the distance up to the injection after the mixing of two solutions is extremely short, the solidification of the adhesive in an apparatus is not generated even when the coating operation of the adhesive is interrupted.
