Title: Novel fluoran derivative and thermal recording material using the same
Inventor: GOTOU HIROSHI
IPC: C09B11/00
Filed: 1983-02-03
Abstract: NEW MATERIAL:Fluoran derivatives of formula I wherein R<1> is lower alkyl; R<2> is lower alkyl, aryl. USE:Coupler components for thermal recording materials. Since the compds of formula I have a methyl group at position 6 and an acetyl group attached to an anilino group, they have low m.p. and can give thermal recording materials having improved heat sensitivity. Further, they are relatively hydrophobic so that the green shelf stability of the thermal recording materials can be improved. PREPARATION:A benzophenone derivative of formula II is reacted with a diphenylamine derivative of formula III in the presence of a dehydrating-condensing agent. The reaction mixture is poured into ice water. The precipitate is filtered, and the resulting crystal is dispersed in an aq. caustic soda soln. The dispersion is stirred, toluene is added thereto and the stirring is again conducted. The toluene layer is recovered, washed with water and concentrated. The precipitated crystal is recovered and recrylstallized from an org. solvent to obtain the desired compd. in a high purity.

Title: Memory processing system
Inventor: IKENO MOTOKIYO
IPC: G06F11/07
Filed: 1989-01-26
Abstract: PURPOSE:To attain an operation equal to that carried out in a normal state in case an extension memory has a fault during a data transfer sequence and no answer signal is transmitted by detecting a time-out state via a timer and producing a pseudo answer signal which is equivalent to a due answer signal. CONSTITUTION:In case an acceptance signal 104 is not transmitted within a fixed time due to the fault of an extension memory 4, a timer 11 detects the time-out state of the signal 104. Thus the fault of the memory 4 is informed to a processor 2 and at the same time a time-out report 102 is given to a pseudo signal circuit 12. As a result, a pseudo acceptance signal 103 is sent to the circuit 12 in placed of the signal 104. An OR circuit 13 secures an OR between both signals 104 and 103 to produce a signal 105 equivalent to the signal 104 and inputs the signal 105 to a request control circuit 10. Thus, it is possible to continue a memory process with no complicated control despite the fault of the memory 4.

Title: Hydraulic controller
Inventor: NAKAGAWA TAKASHI
IPC: F15B11/08
Filed: 1995-02-06
Abstract: PURPOSE: To improve response by using electric current where the pilot oil pressure of the first and second proportional solenoid valves does not operate an actuator at the time of the neutral position of an operating lever, and at the time of operating the operating lever for driving one proportional solenoid valve, by decreasing output current to the other proportional solenoid valve more than at the time of the neutral position of the lever. CONSTITUTION: Controller output current at the time of placing a lever 1 into neutral position is made less than pilot pressure to the degree that an actuator 11 does not start to operate. When the lever 1 is operated, for example, in XA direction from the neutral position, a controller 3 outputs output current IA to a proportional solenoid valve 4, and decreases IB in XB direction where the lever 1 does not operate to low current maintain it. As a result, pilot pressure working upon the spool of a spool valve 10 decreases at the time of placing the lever into a neutral position to keep the operation of a spool in the spool valve 10 quick, so it is possible to make quick response time until the actuator 11 starts to operate after operating the lever 1.
