Title: Production of benzophenones
Inventor: WADA HIROSUKE
IPC: C07C201/00
Filed: 1987-03-30
Abstract: PURPOSE:To produce benzophenones useful for industrial purposes, by reacting benzene with a benzoyl halide at a temperature above a specific level in the presence of a trivalent rear earth metal halide compound in the reaction system, thereby proceeding the reaction at a relatively high rate of reaction. CONSTITUTION:A (substituted)benzene is acylated with a (substituted)benzoyl halide to obtain benzophenones (e.g. benzophenone and 4,4'-dichlorobenzopheno ne). The reaction is carried out in the presence of catalyst consisting of a triva lent rare earth metal halide compound (especially preferably the rare earth metal is lanthanum, cerium, praseodymium, etc., and the compound is an anhy drous rare earth metal trichloride compound) at >=100 deg.C (especially preferably 120-250 deg.C). The catalyst can be repeatedly used. The produced benzophenones are useful as intermediates for perfumery fixer, polymerization inhibitor, ultravio let absorber, photopolymerization initiator and polymer, etc.

Filed: 1981-05-19
Abstract: PURPOSE:To let a consumed horsepower get near a required horsepower by detecting a control signal for a directional control valve and a discharged pressure of a hydraulic pump and feeding back them to control a revolution speed of an engine. CONSTITUTION:Controlling of a revolution number of an engine is made by shifting a throttling lever from a position 9 to 9' to operate a governor 12 of the engine via links 10, 11. A cylinder 13 which contains a piston 17 made up of a large diameter part 17a and a small diameter part 17b is linked to a link mechanism, which performs a flow rate feedback by transferring a pressure Pp correspondent to a controlled level of a directional control valve into a left chamber of the large diameter part 17a, and a flow rate feedback by transferring a discharged pressure Pm of a hydraulic pump into a left chamber of the small diameter part 17b. A problem that by the flow rate feedback only a flow rate can not be adjusted to be proportional to rpm. of the engine due to a fluctuation of pressure has been eliminated, thus an overload of the engine under high pressures is prevented

During casting, the gas permeation characteristic value is continuously calculated and the gaseous Ar flow rate is continuously or intermittently adjusted to a value obtd. by multiplying this permeation characteristic value by the target gaseous Ar back pressure and then, the gaseous Ar back pressure 9 is controlled to the target gaseous Ar back pressure. The control is effected by the both of a automatic operation and a mannual operation.

Title: Automatic ticket checking and collecting machine
Inventor: YAMADA TOMOYUKI
IPC: G07B15/00
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent these card from being reduced or subtracted by performing cancel processing that returns the reduction or subtraction of the stored fare card or a card of tickets to an original state when a train ride section is included in the train ride section of the a season ticket. SOLUTION: When an entrance station exists in read data of a stored fare card (SF card), whether or not the entrance station exists in read train ride section data of a season ticket is decided (S104 yes and S106 yes). For instance, if the entrance station of the SF card exists in the train ride section of the season ticket, a user meets entrance and exit conditions with only the season ticket. Then, entrance data recorded on the SF card is eliminated and also when a first ride fare is reduced at the time of the entrance, cancel processing that returns the reduced amount is performed (S108). Furthermore, when entrance data exists in the communication ticket, the SF card is returned as it is with no processing.

Title: Searching method of communication channel
Inventor: KAMEI MITSUHITO
IPC: H04B10/112
Filed: 1984-04-13
Abstract: PURPOSE:To secure a communication channel with a traveling object by setting a bright point of light on the surface of the traveling object, providing an image pickup means having its viewfield set within a communication enable range to each of plural fixed stations and performing the communication between the traveling object and a fixed station that recognized the traveling object. CONSTITUTION:When a construction 5 exists between a fixed station 2 and a traveling object 1, the communication is cut between these station 2 and the object 1. Therefore a light spot 4 on the object 1 is not detected by a PSD (position sensitive detector) camera 2a set at the station 2 owing to the presence of the construction 5. A signal processor recognizes this state and commands the communication with a fixed station 3 where the spot 4 is detected. The output data of a PSD camera 3a corresponds to the azimuth information of the object 1 when viewed from the station 3. Based on this information, a transmitter/receiver of the object 1 is set opposite to the station 3. Thus a communication channel can be easily secured for communication with the object 1.
