Title: Pulse duration modulating/amplifying circuit
Inventor: YAMAGISHI HIROSHI
IPC: H03F3/217
Filed: 1979-06-14
Abstract: PURPOSE:To reduce the distortion of the output low-frequency signal, by selecting the reference voltage of the 1st and 2nd comparators each in order to secure the minimum distortion factor for the output low-frequency signal supplied from the low pass filter. CONSTITUTION:The input signal sent from input terminal 1 is applied to integrator 10, and then the triangular wave signal of the carrier frequency sent from rectangular wave oscillator 12 is applied to integrator 10. Then the rectangular wave signal is piled onto the input signal, and this piled signal is applied to the 1st and 2nd comparators 13-1 and 13-2 which compare the reference voltage of different reference voltage generation sources each. Thus driving circuits 15-1 and 15-2 are operated by the outputs of comparators 13-1 and 13-2, and the alternating control is given to the ON/OFF of transistors Q1 and Q2 via impedance converting circuits 16-1 and 16-2. Then the reference voltage of these two comparators are selected so as to secure the minimum distortion factor for the low-frequency signal of the circuit which is connected to output terminal 2 of LPF4 to obtain the low-frequency output. Thus the minimum distortion is secured for the output low-frequency signal.

Title: Real time communication method
Inventor: NAKANO TAKAHIRO
IPC: H04L12/40
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To perform data communication guaranteeing a real time property by providing a transmission suppression means for suppressing a transmission opportunity to one time at every fixed interval and suppressing a data amount to be sent out in one transmission to be less than a set data amount in the respective information processors in the LAN system of a CSMA/CD system. SOLUTION: The transmission request module 301 of the respective information processors connects a newly prepared transmission request to a transmission request queue 311 and a transmission suppression module 302 is activated at the interval of the transmission opportunity. At the time of being activated by the transmission suppression module 302, an input/output controller 102 sends out data corresponding to the transfer data length of a specified transmission command to a network. Thus, a transmission data amount does not exceed the data amount transmittable within the interval time of the transmission opportunity by all the information processors connected to the network and the transmission is completed. Thus, without changing an existing hardware, real time communication guaranteeing a band is made possible.

Title: Light-emitting diode
Inventor: FUKUSHIMA AKIRA
IPC: H01L33/40
Filed: 1987-03-27
Abstract: PURPOSE:To reduce a sub-peak by secondary light emission by forming a gallium-arsenide (GaAs) layer, to which an impurity is not added substantially, between a substrate and a first clad layer. CONSTITUTION:With a junction-up type light-emitting diode, a non-doped GaAs layer 9 is shaped onto an n-type GaAs substrate 1. When beams lambdaa generated in a light-emitting region 3a reach to the undoped GaAs layer 9, carriers in the layer 9 are excited and beams lambdaa having a wavelength different from lambdaa corresponding to a band gap are emitted. However, the intensity of photo-luminescence of the undoped GaAs layer is brought to one hundredth or less of the GaAs substrate 1, and the greater part of beams lambdaa reaching to the GaAs layer are consumed by recombination contributing no light emission. Accordingly, the sub-peak of a radiant spectrum by secondary light emission is reduced largely, thus lowering noises to a main peak, then allowing optical communication having high quality.

Title: Ghost rejector
Inventor: YAMAGUCHI NAKAO
IPC: H03H17/00
Filed: 1978-06-20
Abstract: PURPOSE:To simplify the delay element parts of the ghost rejector, by connecting the delay element group having the input terminal at each junction point and the delay element group having the output terminal at each junction point in series. CONSTITUTION:The delay elements 16a to 16j having delay time of 0.1 musec in series connection, and the delay elements 17a to 17e having delay time of 1 musec in series connection are connected in series. Further, the element group 16 has the input terminals 18a to 18j at each junction point, and the output terminals 19a to 19e of each junction of the element group 17 are connected to arbitrary input terminal of the gain and polarity circuits 20a to 20f via the switch 21. Further, the output of the circuits 20a to 20f is connected to the input terminals 18a to 18j via the switch 22. When a signal having the ghost delayed by 3.8 musec is inputted from the terminal 15, the delay time between the points a and b is 3.6 musec by feeding back the output at the point b to the point a, and the ghost at the point a is cancelled. Thus, the delay elements can be simplified.

Abstract: PURPOSE:To form thick dense layers with a high yield by supplying electric power to an electric conductive base film for plating on a substrate from the entire periphery when a magnetic core, a coil, etc., are formed by electroplating. CONSTITUTION:An insulating layer 2 of Al2O3 is formed on a circular Al2O3-TiC substrate 1 by sputtering in 10mum thickness and an Ni-Fe film 3 as a base film for plating is formed on the insulating layer 2 by sputtering in 0.05mum thickness over a larger area than the layer 2. A pattern 9 for a plating layer to be formed is formed on the base film 3 by photolithography with a resist 4, and the substrate 1 is inserted into a holder 5. A power supply plate 6 inside the holder 5 is brought into contact with the rear side of the substrate 1 and a plating layer is formed on the pattern 9 with electric power supplied to the base film 3 from an external power source through a wire 8. Since electroplating is carried out at uniform current density over the entire substrate 1, thick dense layers can be formed with a high yield.

Title: Web winding device
Inventor: TSUJIMURA MIKIO
IPC: B65H18/06
Filed: 1988-03-28
Abstract: PURPOSE:To simply adjust winding work without the occurrence of discrepancy between the centers of rotating shafts of winding reels or their inclination by moving an arm with a projection and a recession provided on the arms engaging mutually to change a space between a pair of the arms. CONSTITUTION:A space between winding reels 30 of a pair of arms 18, 20 is adjusted by moving the arm 18 on the surface of a base 14. In this case, the arm 18 moves with an arm base 14 accurately fitted in a guide member 12 to keep the normal winding positions of the arms 18, 20. In addition, since the arm 18 moves with the projection 22 of the arm 18 engaging the recession 24 of the arm 20 to be positioned, discrepancy between the axial centers of the winding reels 30 and their inclination do not occur. Thus accurate winding work can be easily performed according to an alteration in the cut width of a web.

Title: Silver halide photographic sensitive material and its manufacture and image forming method by using same
Inventor: ITO HIROHIDE
IPC: G03C1/09
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain the photographic sensitive material capable of forming an image high in contrast and stability by exposure in an extremely short time by using >=2 kinds of silver halide emulsions different from each other in an adsorption amount of a hydrazine derivative. SOLUTION: The silver halide emulsions to be used are >=2 kinds of emulsions different from each other in an adsorption amount of the hydrazine derivative. The adsorption amount of the hydrazine derivative can be changed by adding the hydrazine derivative until mixing each emulsion, or adding it after mixing the emulsions and after finishing chemical ripening in order to prevent uniformization of the hydrazine derivative and it is especially preferred to add it after finishing the chemical ripening until adding a sensitizing dye. It can be attained also by adding the hydrazine derivative stronger in adsorbing power to the emulsion more in an amount of adsorbing the hydrazine derivative. It is preferred that the sensitivity of the emulsion is lower in the absence of action of the hydrazine derivative, in the case that the emulsion more adsorbs the hydrazine derivative.
