Title: Method for synthesizing bis(nitrophenoxy)xylenes
Inventor: MIYATA SHIRO
IPC: C07C205/37
Filed: 1990-05-11
Abstract: NEW MATERIAL:Bis(nitrophenoxy)xylenes expressed by formula I. EXAMPLE:Bis (p-nitrophenoxy)-p-xylene. USE:Precursors of xylylene dications, used as raw materials for resins, crosslinking agents, curing agents, etc., and expressed by formula II (L is leaving group). Since the aforementioned compounds are hardly volatilized even at high temperatures and electrophilic aromatic substitution reaction is not inhibited by eliminating reaction products, the electrophilic aromatic substitution reaction can be carried out under conditions of higher temperatures than those in conventional methods. PREPARATION:Nitrophenols expressed by formula III (X is H or alkali metal) are reacted with a xylylene dihalide expressed by formula IV (Y and Z are halogen) in the presence of a base such as tertiary amines such as 1,8- diazabicyclo[5.4.0[undecene in a solvent such as N,N-dimethylforamide normally at -20 deg.C to the refluxing temperature of the solvent used for 0.5-24hr to efficiently afford the objective compounds expressed by formula I.

Title: Message display device for telephone set
Inventor: NISHIMURA KOJI
IPC: G09G3/20
Filed: 1989-05-12
Abstract: PURPOSE:To display a message in a leftward flow state by storing a message which is larger than the number of display digits and shifting its display at constant intervals of time. CONSTITUTION:The message (e.g. 13 characters) is written in addresses 0 - 13 of a display buffer memory 3 in order and a blank display is inserted at the tail. The address of a display control circuit 2 returns to the head address when the blank display is detected and the same message is displayed repeatedly. A display device has 9-digit constitution, so the circuit 2 outputs head addresses 0 - 8 to the memory 3 in order at time 1 and display data is read out and displayed on the display device 1. At this time, the output of a timer circuit is 0. At time 2, an adding circuit 5 adds the output +1 of the circuit 4, the address and addresses 1 - 9 of the memory 3 are accessed, and the character data in the addresses 1 - 9 are read out by the circuit 2 and displayed. At constant intervals of time, the time changes to 3, 4... therefore, the output of the circuit 4 increases by +1, and the access area on the memory 3 changes one by one, so the image flows to the left and all characters are displayed.

Title: Inspecting apparatus of leakage of gas
Inventor: OCHIAI EIJIRO
IPC: G01M3/20
Filed: 1989-05-12
Abstract: PURPOSE:To increase an efficiency of ionization of gas, to lower the background of the gas and thereby to attain an improvement of precision in detection and reduction of a time for inspection by providing an ionizing means of an analysis tube in a channel of the gas introduced from a test port. CONSTITUTION:A gas introduced from a probe nozzle 11 by opening a test valve 1 passes through an ion source element of an analysis tube 3 via a cold trap 2 and is introduced into a cold trap 7. Thereafter the gas is exhausted through a conductance valve 4. Accordingly, the whole of the quantity Q of the introduced gas is passed through the tube 3 and ionized, and therefore the sensitivity of detection is increased. A partial pressure of helium being necessary for detection is obtained even when an effective exhaust speed is increased, a staying time of the gas introduced into the tube 3 is shortened and the background is lowered, while a sensing time is shortened as well. Thereby it is possible to improve the sensitivity of detection of the gas and to shorten a time for inspection.

IPC: G01K7/20
Filed: 1988-05-17
Abstract: PURPOSE:To always measure a temperature with high accuracy by changing a dynamic range of an A/D converter, based on a result of comparison by a comparing means. CONSTITUTION:A constant current (i) from a constant-current source 3 flows to a resistance bulb 1, and in one end of a lead wire 2, voltage signals VA-VC are generated, respectively. These voltage signals are selected successively by a switch 4, and converted to digital signals by an A/D converter 5. Also, a wiring resistance arithmetic means 61 calculates a wiring resistance r3 of a signal path. A comparing means 62 compares a value of this resistance r3 and a prescribed wiring resistance value which has been set in advance, and by its results, whether a current limiting resistance has been inserted into the signal path or not is known. When the wiring resistance is larger than a prescribed value, it is decided that the current limiting resistance has been inserted, and a dynamic range of the converter 5 is set to a regular mode, and when the wiring resistance is smaller than the prescribed value, it is decided that the current limiting resistance is not inserted, and the dynamic range is switched so as to become a high resolution mode.

IPC: H04M1/71
Filed: 1977-10-06
Abstract: PURPOSE:To detect extension response, etc., surely without requiring the readjustment dependent upon the number of connected telephone sets, cable length, etc., by discriminating the potential difference between the voltage level of a control line at a response time and the voltage level at an originating time in a main unit. CONSTITUTION:When an extension originating occurs in telephone set No.1, the divided voltage level of +V power source is generated in control line 14, and this level is supplied to potential difference discrimination circuit 70 after being stored in memory circuit 60 through gate 50 over a fixed time. Then, simultaneously, the voltage level which is obtained by subtracting a fixed voltage from the voltage level of control line 14 is supplied to circuit 70, thereby making the output of circuit 70 low-level. Next, in case that telephone set No.n has answered, the voltage of +V power source is divided, and the voltage level of control line 14 is increased. Then, when this level is over a fixed voltage, the output of circuit 70 is inverted from a low level to a high level, thereby discriminating a response state.
