Title: Telephone system for mobile body
Inventor: WATANABE HIROSHI
IPC: H04W88/02
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To protect privacy of a possessor in the case of voice output of a memory dial registered in a portable telephone set in the hand-free telephone system for a mobile body. SOLUTION: With a portable telephone set 100 set to a cradle 200, a microcomputer 22 in the cradle reads a memory number and its telephone number stored in advance in the portable telephone set 100. The user uses a microphone 36 to enter a name of a dial destination to each memory number and stores it to a recording and reproducing circuit 26. When the user operates an operation switch 38 to select any of memory numbers, the microcomputer 22 reads aloud the memory number, the registered call destination (name) and the telephone number in voice, and in the case that the telephone number read from the portable telephone set 100 and the telephone number at registration of the name does not match with each other, reading aloud of the destination (name) in voice is inhibited.  Thus, even when the portable telephone set 100 of other party is set on the cradle, its call destination is not outputted in voice.

Title: Polyphenylene oxide molding material
Inventor: MIYOSHI KEIJI
IPC: H01B3/42
Filed: 1990-03-15
Abstract: PURPOSE:To prepare the title material having excellent electrical properties in a high-frequency region and a high heat resistance by compounding a compsn. comprising a polyphenylene oxide, a crosslinker, and an initiator with an inorg. filler. CONSTITUTION:A compsn. comprising a polyphenylene oxide [e.g. poly(2,6- dimethyl-1,4-phenylene oxide)], a crosslinker (e.g. triallyl isocyanurate), and an initiator (e.g. Perbutyl P) is compounded with an inorg. filler (e.g. CaCO3) to give the title material, which gives a molded article exhibiting excellent electrical properties in a high-frequency region because of low dielectric constant and dielectric dissipation factor inherent in the polyphenylene oxide. The polyphenylene oxide compounded is crosslinked by the crosslinker to give a highly heat-resistant crosslinked polymer, and the inorg. filler compound strengths the resistance to heat distortion, thus giving a molded article with a high heat resistance.

Title: Highly permeable composite reverse osmosis membrane
Inventor: HIROSE MASAHIKO
IPC: B01D69/12
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To efficiently and economically use a highly permeable composite reverse osmosis membrane for the removal of not only an ion but also an organic matter, as the membrane maintaining a high salt blocking rate and also a high water permeating capability and further, an outstanding performance of blocking an organic matter such as isopropyl alcohol. SOLUTION: Isopropyl alcohol is added to a solution containing m-phenylenediamine, then this aqueous solution is kept in contact with a porous polysulfone support layer for a few seconds, and some surplus amount of the aqueous solution is removed to form a layer of the aqueous solution on the support layer. In addition, a solution containing trimesyl chloride and isopropyl alcohol is caused to come into contact with the surface of the layer of the aqueous solution, then is dried in a hot blast drier to form a polymer thin film on the support layer, and thus a composite reverse osmosis membrane is obtained.  For the performance of the obtained composite reverse osmosis membrane, the salt blocking rate is 95% in terms of permeable liquid electroconductivity, the permeation flux is 1.1m<3> /m<2> /day and the isopropyl alcohol blocking rate is 65%, as shown by the evaluation of a salt solution with a pH value of 6.5 containing 500ppm of sodium chloride at a pressure of 5kgf/cm<2> .

Title: Surface modification method for surface treated steel sheet
Inventor: SATO NOBORU
IPC: C23C22/78
Filed: 1989-03-16
Abstract: PURPOSE:To modify a buffed surface and to obtain a coated surface excellent in rust resistance by applying pulse irradiation with YAG laser with a specific energy to the buffed modified surface of a surface treated steel sheet. CONSTITUTION:Prior to chemical conversion treatment in a coating process, a surface treated steel sheet, such as alloying hot dip galvanized steel sheet, is ground by means of buffing, by which a deformed part is shaped and smoothed. Subsequently, pulse irradiation with YAG laser is applied with <0.6-1.0J/pulse energy to the buffed modified surface mentioned above. By the above laser irradiation, a Zn-enriched layer formed on the above modified surface can be effectively reduced without leaving pulse flaw in the surface. By this method, the buffed surface can be modified and rust resistance can be improved, and further, by carrying out chemical conversion treatment and electrodeposition coating subsequently, the coated surface excellent in rust resistance can be formed.

Filed: 1991-03-29
Abstract: PURPOSE:To reduce the opening area of an incident window, to reduce the opening ratio of an integrating sphere and to make it possible to measure the diffused reflection only based on the diffused reflection component by providing the constitution wherein luminous fluxes are cast into two reflection measuring windows at an incident angle 0 and a specified incident angle. CONSTITUTION:A main body 1 of an integrating sphere has two reflection measuring windows, wherein a sample 2 whose reflection is measured or a standard sample 2 is arranged. Incident windows A and B, through which measuring luminous flux or reference luminous flux is cast, are provided in correspondence with the reflection measuring windows. The window A is set so that the incident luminous flux 3 is cast on the sample at the specified incident angle and the reflected luminous flux 4 does not return to the incident window again. The incident window at the side A has the opening area of the size, which can sufficiently pass only the incident luminous flux, because the luminous flux 3 has the specified incident angle and the entire reflected luminous flux from the corresponding sample is supplemented with the inner wall of the integrating sphere. Namely aXb (a<a' and b<b'). Therefore, the area of the outer shaded part is increased, and the opening ratio is reduced by that amount.

Title: Arithmetic processor
Inventor: NAGAFUJI MOTOYOSHI
IPC: G06F7/508
Filed: 1982-04-19
Abstract: PURPOSE:To perform an addition/subtraction of a half word length operand at a speed exactly equal to that of a word length operand and without producing a delay of the overall processing speed, by using a preshifter of an operator for the part corresponding to the process of a shifter. CONSTITUTION:An advance controller sets ''0'' and the 2nd opened data (111...10) to the first half (bit 0-15) and the second half (16-31) of a work register (A) 30 respectively. These ''0'' and operand data are fed to an improved preshifter (A) 100. Only the half word length addition arithmetic mode is applied to the first half of the preshifter 100 as a control signal, and other modes are all suppressed. As a result, an AND circuit 901 is energized since the 2nd operand is equal to a negative code, and the output of an OR circuit 910 is set at ''1''. The TRUE (through) is applied to the second half of the preshifter 100 as a control signal in the case of addition. Then the set 2nd operand data is inputted as it is directly into an operator.

IPC: G06F21/64
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a prepaid card system or the like capable of preventing a forgery of a copy or the like. SOLUTION: When variable information updated according to the amount of consumed money is written onto a card, the reading and writing apparatus reads two pieces of variable information from a variable region EA1, and records and updates one of them which has not been recorded and updated at the previous use of the card. Then, characteristic data is obtained as a distance value between characteristic sections corresponding to the two pieces of the variable information in the variable region EA1. The characteristic data of the non-updated variable information is allowed to be contained in the variable information to be recorded in a variable region EA2, and encrypted with the characteristic data of the updated variable information being used as a key to be recorded and updated. After completing the recording and updating of the two pieces of the variable information into the variable regions EA1, EA2, the characteristic data of the two pieces of the variable information in the variable region EA1 is obtained, and the variable information in the variable region EA2 is decoded with the characteristic data of the updated variable information being used as a key. Then, it is discriminated whether or not the characteristic data of the non-updated variable information coincides with the characteristic data contained in the decoded variable information.
