Title: Manufacture of activator for zinc phosphate treatment
Inventor: DEIITERU IENSHIYU
IPC: C01B25/37
Filed: 1991-04-22
Abstract: PURPOSE: To obtain an activator for a metallic surface treatment which is helpful for improving the corrosion preventiveness of a zinc phosphate film layer and the adhesiveness of a coating material film by making a soln. of Ti compds. alkaline and combining this soln. with orthophosphoric acid, then stirring and maturing the soln.  
     CONSTITUTION: One or plural Ti compds. are dissolved into water or an acid under careful intimate mixing conditions and a water-soluble alkali is added to the soln. to make the soln. alkaline. While the soln. is maintained at an alkaline pH value, the soln. is combined with the orthophosphoric acid. The soln. is then stirred and matured for at least 15 minutes under a pressure of atm. pressure to 300 bar at 70 to 90°C. The stage described above is executed at ordinary temp. to 45°C at the time of executing the maturation under atm. pressure to 1 bar and the stage described above is executed at ordinary temp. to 90°C at the time of executing the maturation under 1 to 300 bar, by which the activator is obtd. If this activator is applied to the metallic surface, the zinc phosphate film having good adhesion property is easily formed.

Abstract: PURPOSE:To give the right of talking start to the called party by providing a reception circuit and a control circuit or the like for a polarity inverting pulse or an MF signal to a telephone set and allowing a converter to transfer a caller data to a called party according to a signal from a subscriber in the form of a polarity inversion pulse or an MF signal thereby informing the presence of a call and its content to the called party. CONSTITUTION:The telephone number of a caller is sent in the form of a polarity inversion pulse of an MF signal by the hooking-off of a telephone set. The signal is received by a reception circuit 4a and stored in an additional memory 8a. A control circuit 6a reads a signal stored in the memory 8a, inputs the signal to a latch circuit 10 and displays on a display device 12 via a drive circuit 11 or raises a buzzer 13 to inform the incoming call to a called party. Further, the control circuit 6a lights a lamp 7a in a button matrix when the telephone number of the caller stored in the additional memory is a telephone number stored in the memory 8. Thus, it is possible for the called party to reply or not depending on its convenience.

Abstract: PURPOSE:To make it possible to perform the operation test of a simpl substance by constituting the polarity function of a service current with four switch circuits. CONSTITUTION:When the loop operation test is performed by a simple substance, a control signal is sent to control circuit 16 to turn on switch circuits 10 and 11, and the loop of ground-current supply circuit 15-current detection circuit 14-circuit 11-circuit 10-circuit 14-circuit 15-power source 17 is constituted in the trunk circuit. Then, the loop current supplied from circuit 15 is detected by circuit 14; and it can be confirmed that respective circuits are normal in case of current presence and any of circuits 16, 10, 11, 14 and 15 is faulty in case of current absence. Otherwise, various tests can be performed by combining switch circuits as required and operating them. Next, when the loop operation test in the trunk circuit side is performed, the polarity switching circuit of one of A and B lines is conventional, and only the other can be constituted by switch circuits which can be controlled individually.

Title: Image data read system
Inventor: MORI HIROMI
IPC: G06T1/60
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To provide the image data read system which receives normally image data even when a long time is required for reception processing of the image data. SOLUTION: When a time of 30sec elapses (S87: Yes) after reading of image data is instructed to a monitor program (S5), whether or not reading is conducted is inquired of the monitor program (S9). In the case of receiving a message denoting a reading state from the monitor program (S11: Yes), no time-out processing is conducted but a 30sec time count is reset and the processing from the S7 to the S13 is repeated till a message denoting end of reading of one page is received from the monitor program. On the other hand, when a message denoting the reading state is not received from the monitor program (S11: No), a scanner driver informs the occurrence of error to a viewer program of a start source (S23), and the read processing is terminated (S21, S25).

IPC: C02F9/00
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To improve the decrease of total organic carbon by adding alkali bromide and ozone in raw water and irradiating an ultraviolet ray to decompose organic materials. SOLUTION: After pretreating raw water in a preliminary treating device, about 1 ppm ozone and 1 ppm NaBr are injected to permeated water desalted by, a reverse osmotic membrane separation device in a primary pure water producing device 2. Then, the permeated water is fed to a UV oxidation device to be irradiated with UV after retained in a reaction column. The MB treated water is obtained by adding about 0.5 ppm NaHSO3 in the water flowing-out from the UV oxidation device and ion-exchanging in an ion exchange demineralized water device. By the constitution, the total organic carbon(TOC) is effectively decomposed and ionized by the UV oxidation and further the TOC in the treated water is extremely reduced by removing it in the ion exchange demineralized water device up to a very low concentration.

IPC: B62D1/04
Filed: 1978-09-27
Abstract: PURPOSE: To reduce the weight and improve the dimensional accuracy of the steering wheel by constructing the steering wheel body ring with a metal plate material.  
     CONSTITUTION: A sheet-shaped metal base materials is used for the ring member of the steering wheel and a sheet shaped ring 1 is molded into the form of a pipe after the spoke 2 and the ring are joined together. Then, a hole 3 is made on a metal plate base material for the ring. A metal sheet is coiled like a ring inserting the spoke 2 into the hole 3 and the both ends thereof are welded. Then, the spoke 2 and the metal sheet are welded together. The ring-shaped metal sheel is wrought into a pipe by a roll molding or a press molding. Because the shape of ring and the dimensional accuracy are determined as to the steering wheel during the process, a product can be finished without affecting the dimensional accuracy of the ring 1 due to a thermal distortion by welding when the spoke 2 and the sheet-shaped ring 1 are joined together.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal panel in which a liquid crystal structure improves its orientation property and can move enough to eliminate defects by forming a frame by adhering a pair of substrates having a specified coefft. of linear expansion with a stripe supporting body for substrates having specified spaces. SOLUTION: A pair of substrates 501, 501' are adhered with a supporting member 504 for substrates having ribs formed between electrodes 502 on one substrate, and a liquid crystal is sealed in the straight spaces 506 thus formed. The substrates 501, 501' have <=60×10<-7> / deg.C coefft. of linear expansion in a practical temp. range, such as from -20 deg.C to 150 deg.C, and a nonalkali glass or silica glass is used. The width D of the space 506 to seal the liquid crystal is controlled to 80 to 300μm as the optimum range when the substrates are cooled under a certain temp. gradient condition, and preferably 80 to 250μm. If the width D of the space 506 to seal the liquid crystal is over the range, the liquid crystal hardly moves by contraction.  If the width is less than the range, it increases the probability that the liquid crystal produces band-like fringes or moves too much to damage an aligned layer structure.
