Inventor: YOSHIDA HIROSHI
IPC: C07C69/716
Filed: 1985-04-19
Abstract: PURPOSE:To obtain the titled substance, by subjecting a reaction solution containing a dialkyl maleate obtained from maleic acid (anhydride) and an alcohol to specific treatment, and reacting said ester with an aliphatic aldehyde in the presence of a peroxide catalyst. CONSTITUTION:Maleic acid (anhydride) and a 1-8C alcohol are fed in a molar ratio 5-7 of excess alcohol, and subjected to esterification reaction in the presence of an acid catalyst (example; strongly acidic cation exchange resin) at 80-100 deg.C while a formed water is stripped out of the reaction system with the alcohol t obtain a dialkyl maleate. Then after an acid component in the reaction solution is neutralized with a basic substance, the resultant reaction solution is heated at 80-100 deg.C for 0.5-1hr to convert a by-product formed through the esterification process into an acid by thermal decomposition, and this acid is reneutralized with the basic substance. Thus obtained crude dialkyl maleate is reacted with a 1-4C aliphatic aldehyde in the presence of a peroxide catalyst to obtain the aimed substance in high purity and high yield.

Title: Terminal equipment access system
Inventor: SUGAWARA NOBUAKI
IPC: H04M11/00
Filed: 1986-04-09
Abstract: PURPOSE:To access a terminal equipment by a DP telephone set by providing a means which converts number information received from a public station into terminal control information. CONSTITUTION:When a caller dials a number of a terminal equipment T via a public line, a call signal is sent from the public station LS to a PBX. The PBX connects a PB receiver PBR and a trunk line trunk COT and sends a primary reply signal to the LS. When the LS detects a primary reply signal, the number information is sent to the PBX. The PBX converts the number information into terminal control information to control the terminal equipment, sends it from a sender SND to activate the terminal equipment T. On the other hand, since the LS sends a ringing tone or a busy tone to the caller, the caller identifies the propriety of the terminal control by the signal tone. Thus, the terminal equipment is accessed by the DP telephone set.

Abstract: PURPOSE:To obtain the considerably excellent starting characteristic and the flux maintaining factor by making the average grain size of the electron emission material for a discharge lamp electrode having the electron emission substance to be specific times that of the heat-resistant metal. CONSTITUTION:In an electron emission subsistance where the mixing ratio of W is higher than 50wt%, the compound such as Sc2O3 or Sc2WO6 produced through the reaction between Sc2O3 and W during the electrode heating process is reacted with W under high temperature during the lighting of lamp to form the free electron of Sc which will reach through the grain field of W to the surface of the emission subsistance to lower the work factor of the electrode. Consequently the average grain size of the electron emission subsistance is made to be 0.01-5 times that of the heat-resistanct metal. Consequently excellent starting characteristic and the deterioration characteristic is achieved resulting in a discharge lamp where there is no incomplete starting.

Title: Driving circuit for two-phase dc brushless motor
Inventor: KAWATE YOSUKE
IPC: H02P6/08
Filed: 1992-03-05
Abstract: PURPOSE:To facilitate a low speed rotation drive by energizing two phases of a motor driving coils to drive a rotor at the time of rotating at a high speed and energizing one phase of the coil at the time of rotating at a low speed. CONSTITUTION:Currents are supplied to motor drive coils(MC) L1, L2 at the time of high speed rotation, and an H/L signal is output from a comparator IC1 in response to a pole of a rotor. At the time of the H signal, a transistor(Tr) Q1 is turned ON. Thus, a current flows to the MC L1, and a rotary force is applied to the rotor by an electromagnetic force. Then, at the time of the L signal, the Tr Q1 is turned OFF, and no current flows to the MC L1. In this case, a Tr Q2 is turned ON. Thus, a current flows to the MC L2, and a rotary force is applied to the rotor by an electromagnetic force. At the time of rotating at a low speed, when the H signal is input to an input terminal T1, a Tr Q3 is turned ON, and no current flows to a base of the Tr Q2. Accordingly, only the Tr Q1 is solely operated, and the MC L1 is intermittently energized according to the rotation of the rotor.
