Title: Solder paste
Inventor: OCHIAI MASAYUKI
IPC: H01R4/02
Filed: 1989-12-06
Abstract: PURPOSE:To prevent the increase in the viscosity during preservation and to improve workability by using the ammonium halide compd. expressed by specific molecular formula as an activator. CONSTITUTION:The ammonium halide compd. expressed by the following molecular formula is used as the activator for the solder paste formed by adding and kneading at least rosin, org. solvent and activator with solder powder. The formula: MR4<+>X<->, where R is an alkyl group, such as CH3 or C2H5; X is a halogen atom. The soldering temp. of generally used tin/lead (Sn-37Pb) solder is >=230 deg.C and, therefore, the activation effect similar to heretofore is exhibited at the soldering temp. if the ammonium halide compd. which separates at about 230 deg.C is used. On the other hand, this compd. is extremely safe at ordinary temp. The increase in the viscosity during preservation is prevented in this way.

IPC: A47G9/02
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To impart proper flexibility to a thick bedquilt, properly fold this up, and compactly house this by punching raw cotton by a needle punch, forming its needle punch punching areas at intervals in the width direction of the raw cotton, and using this as intermediate cotton. SOLUTION: Raw cotton 1 is punched by a needle punch. The needle punch has plural holders 2.

Title: Television system
Inventor: KAWAI TATSUJI
IPC: H04N5/445
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To easily find which television(TV) channel or video signal is watched at present by displaying a character string corresponding to the operation of an operating means when the operating state of a display device is changed. SOLUTION: When any channel number is selected, a CPU 12 sends out a control signal to a TV reception circuit 13, receives and demodulates a TV broadcasting wave corresponding to the pressed channel number and at the same time, the character string corresponding to the possessed channel number is read out of a character string group stored in a 2nd storage area 202. Next, the character string data corresponding to the read selected channel number are transmitted to a VDP 17. Based on the character string data, the VDP 17 generates a superimposed picture. While controlling a synthesizer circuit 15, the CPU 12 synthesizes the received image of TV broadcasting with the video signal of the superimposed picture outputted from the VDP 17 and displays a synthetic image overlapping character indication on the image of TV broadcasting on a CRT 11.

Title: Psa switchover valve system
Inventor: YAMAMOTO HIROTERU
IPC: B01D53/04
Filed: 1987-12-15
Abstract: PURPOSE:To simplify a valve system of PSA gas purifier, by providing a three or more way valve which, by switching action, can be connected with only one of a raw gas supply pipe, a washed gas supply pipe and a deodorized gas pull-out pipe connected to an inlet of an absorbing tower. CONSTITUTION:The raw gas is sent from a pipe 7 to an absorbing tower 6A through a four-way valve 21 and the exhaust gas resulting from the adsorption of a target gas is delivered to a pipe 19 through a four-way valve 20. In the subsequent washing process, the target gas is sent from a blower 11 to the adsorbing tower 6A through pipes 13 and 10 and the four-way valve 21 to force the off-gas out of the tower and said gas is sent from a pipe 20 to a pipe 7 through the four-way valve 21. In a detaching process, the pressure of the adsorbing tower 6A is reduced by a vacuum pump 15 and the detached gas is sent from the four-way valve 21 to a gas holder 12. In a pressure raising process, the washed exhaust gas is sent from an adsorbing tower 6C to the adsorbing tower 6A through pipes 7 and 9 and the four-way valve 21 for a rise in the pressure. The use of such four-way valve prevents the inclusion in a product gas of the other gases in the event of valve malfunctions.

Title: Inverter controller
Inventor: KAMEYAMA TOMOYASU
IPC: H02M7/537
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain a controller for inverter driving a motor or the like in which the output current is controlled accurately by correcting the output voltage accurately. SOLUTION: Output voltage from an inverter is detected by a voltage detection circuit 19 and the error from a voltage command value is determined by a voltage error operating unit 21. A dead time compensation amount memory section 18 stores the relationship between the voltage error and the output current value detected by a current detection circuit 20. Subsequently, a dead time compensation amount operating unit determines a dead time compensation amount from the dead time compensation amount memory section 18 based on a current command value and an adder 16 adds the dead time compensation amount to the voltage command value thus producing a corrected voltage command value. Operation of the inverter is controlled based the corrected voltage command value.
