Title: Spool type direction selective valve system
Inventor: OHIRA SHUJI
IPC: F16K3/24
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To control an actuator accurately by operating a spool in strict conformity to the command value of an operational signal even in case a force other than the pilot pressure, such as a fluid force or friction force, acts on the spool. SOLUTION: At the two ends of a spool 2, pressure sensors 20a and 20b are installed so as top be in contact through springs 10a and 10b, and from the signals generated, a controller 40 calculates the hydraulic force Fa due to the pilot pressure acting on the spool 2 and the actual driving force Fm acting on the spool 2 actually. The ratio Fa/Fm is multiplied by the command value Voa of an operational signal 50 to calculate the feedback correction value Vr for the hydraulic force, and from the command value of the operational signal, the obtained correction value is subtracted, and thus the command value undergoes a correction. The corrected command values V30a and V30b are fed to solenoid valves 30a and 30b.

Title: Pulse width adjustment circuit
Inventor: SOFUE TOSHIHARU
IPC: H03K5/04
Filed: 1989-11-28
Abstract: PURPOSE:To obtain easiness and high accuracy by connecting a level shift transistor(TR) between an output resistor of a pre-stage ECL circuit and a ground point being a main circuit section so as to control a current flowing to a shift level adjustment resistor. CONSTITUTION:A current I drawn to a current control circuit CC flows to a shift level adjustment resistor R1 connecting between a ground point and a base terminal of a level shift transistor(TR) Q5. Thus, the level of an emitter terminal of the TR Q5 is shifted to a low level by a value r1.I being a product between the current I and a resistance r1 of the resistor R1. As a result, a level of a signal outputted from a pre-stage ECL circuit is shifted to the low level by the value r1.I. A signal with a different pulse width in response to the shift level is generated by gating the signal output subject to level shift in a post-stage ECL 2 by a prescribed reference voltage.

Title: Air supply/exhaust tube
Inventor: KAMEYAMA SHUJI
IPC: F23L17/04
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce the resistance to the supply of air and suppress recirculation of the exhaust gas when there is a strong wind by providing in the front side of an exhaust top an air supply hole and an exhaust hole, inside the exhaust top an exhaust-deflecting plate which deflects the exhaust in a direction separating from the air supply hole in the front side and directs it to the exhaust hole, and in the back side of the exhaust top an air passage opening. SOLUTION: In the front plate 5 of an exhaust top 3 a front air supply opening 6 is formed in the upper part and an exhaust opening 7, thereunder. Inside the exhaust top 3 an exhaust- deflecting plate 8 is provided, which, on the one hand, partitions the inside of the exhaust top 3 into an exhaust passageway 9 and an air supply passageway 10 and, on the other hand, turns the exhaust passageway 9 slantingly downward and brings this passageway to the exhaust opening 7. In the back plate of the exhaust top 3 an air passage opening 13 is provided at a position opposed to the front air supply opening 6 in the upper part.  When there is no wind or the wind is gentle, the exhaust gas flows from an exhaust tube 1 into the exhaust passageway 9 and the exhaust-deflecting plate 8 deflects the flow slantingly downward and makes the exhaust gas flow out from the exhaust opening 7 to the front in a slantingly downward direction. Thus the exhaust gas flows away far from the front air supply opening 6 and an air supply opening 4 in the rear of the exhaust top 3.

Title: Production of alkenylthiophenol and ester thereof
Inventor: ASLAM MOHAMMAD
IPC: C07C49/245
Filed: 1987-12-08
Abstract: A method is provided for preparing alkenylthiophenols, e.g. para-vinylthiophenol, or their esters, e.g., para-vinylthiophenol acetate by reacting a hydroxy aromatic ketone, e.g., 4-hydroxyacetophenone (4-HAP) with an N,N-di(organo)thiocarbamoyl halide, e.g., N,N-dimethylthiocarbamoyl chloride (DMTC) to form an O-(acylaryl) N,N-di(organo)thiocarbamate, e.g., O-(4'-acetophenyl) N,N-dimethylthiocarbamate, and pyrolytically rearranging the latter compound to form an S-(acylaryl) N,N-di(organo)thiocarbamate, e.g., S-(4'-acetophenyl) N,N-dimethylthiocarbamate. In one procedure, the latter compound is directly reduced to form an S-(1-hydroxyalkylaryl) N,N-di(organo) thiocarbamate, e.g., S-[4'-(1-hydroxyethyl)phenyl] N,N-dimethylthiocarbamate, which is either hydrolyzed to form a (1-hydroxyalkyl) thiophenol, e.g., 4'-(1-hydroxyethyl) thiophenol, which, optionally after acylation of its thiol group, is dehydrated to form the alkenylthiophenol wherein the double bond is at the ring-bonded carbon atom, e.g., para-vinylthiophenol, or the S-(1-hydroxyalkylaryl) N,N-di(organo) thiocarbamate is dehydrated to form an S-(alkenylaryl) N,N-di(organo) thiocarbamate, e.g., S-(4-vinylphenyl) N,N-dimethylthiocarbamate which is hydrolyzed to form the alkenylthiophenol. In an alternative procedure, the S-(acylaryl) N,N-di(organo)thiocarbamate is hydrolyzed and the resulting thiol acylated with an acylating agent, e.g., acetyl chloride, to produce an acylthiophenol ester, e.g., 4-acetothiophenol acetate, which is then reduced and hydrolyzed to produce the (1-hydroxyalkyl) thiophenol. The latter compound is then dehydrated to produce the alkenylthiophenol, or acylated and dehydrated to produce the alkenylthiophenol thioester, as described in the first procedure.

Title: Traffic lane separation mark
Inventor: MUTA KEISUKE
IPC: E01F9/594
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of visibility by erecting a tubular marker section on a pedestal section, sticking recursive reflecting sheets on the outer periphery of the marker section, and sticking a translucent protective film on the outer periphery of the marker section to cover the reflecting sheets. SOLUTION: A tubular marker section 2 made of a soft urethane resin and having a proper shape such as a conical shape or a cylindrical shape is erected on a pedestal section 1 installed on a road surface. Belt-like recursive reflecting sheets 3 are stuck in the peripheral direction on the outer periphery of the marker section 2. The outer periphery of the marker section 2 is coated with a translucent paint mainly made of a urethane resin, and a protective film 4 is integrally stuck to form a traffic lane separation marker. Since the protective film 4 is stuck, the recursive reflecting sheet 3 can be prevented from being broken and peeled when a vehicle collides with the separation marker and treads on it, and the reduction of visibility at night can be prevented.

Abstract: PURPOSE:To obtain a light emitting element having a short wavelength such as a stable high luminance blue light emitting diode having high reproducibility by forming an n-type layer of a junction of zinc and a p-type layer of a II-VI compound semiconductor layer containing M, B, Te (M is Cd or Zn). CONSTITUTION:An n-type layer 1 of a junction is formed of a II-VI compound semiconductor layer 1 containing zinc as an indispensable composition element such as a ZnSe single crystal substrate 1. A p-type layer 2 of the junction is formed of a II-VI compound semiconductor layer made of an epitaxial layer (epitaxial film) containing M, Be, Te (M is Cd or Zn) as indispensable constitution elements such as a CdBeTe:As layer 2. An Al negative electrode 40 and an Au positive electrode 50 are formed by vapor-depositing and forming ohmic properties. Since the layer 1 is formed of single crystal or equivalent homoepitaxial (class) high quality single crystal, its recombination light emitting efficiency can be improved. Further, an injecting efficiency can be improved. Thus, stability and reproducibility can be enhanced.
