Title: Production of casting mold
Inventor: HASEGAWA SHIGEO
IPC: B22C9/04
Filed: 1984-07-28
Abstract: PURPOSE:To obtain a casting mold which is free from the disadvantages by foamed polystyrene in a full mold method by manufacturing the casting mold by using a foamed molding of a high-polymer material then shrinking and solidifying the foamed molding by an electrical heating element attached thereto and removing the molding from the mold inside. CONSTITUTION:Molding sand is molded by using the pattern attached with the heating element to be electrically heated to, for example, the foamed polystyrene molding and thereafter electricity is conducted to both terminals of the heating element on the outside of a molding flask to heat the molding by said heating element until the surface temp. of the molding attains 100-200 deg.C. The above- described pattern is shrunk and solidified and the polystyrene residues produced therein are removed together with the heating element from the mold inside. A molten metal is cast into the cavity of the mold formed in such a manner, by which the casting is manufactured. Problems such as the generation of black smoke and fire column by the gas generated from the PE in the full mold method and the generation of blow back of the molten metal by the back flow of the generated gas in a runner are eliminated in this stage. There is also an advantage in that the low expansion type polystyrene can be used.

Title: On-load tap changer
Inventor: FUWA YASUSHI
IPC: H01F29/04
Filed: 1986-07-01
Abstract: PURPOSE:To enable tap changing to be performed even if higher harmonic components overlap load current, by computing an output signal of a current detector and then controlling an ignition signal so as not to be temporarily inputted into an ignition circuit of thyristors when the computed period is below a definite value. CONSTITUTION:If winding taps 3a and 3b are connected with tap selectors 2a and 2b, respectively, together with thyristors 1a, 16 being in ignition states and 1c, 1d being in non-ignition states, then current flows in the route of the tap-winding tap 3a. the tap selector 2b-the thyristors 1a and 1b - a load 16. When tap downward changing is performed from the winding taps 3a to 3a, the downward changing operation allows downward-detection contacts 11a and 11b to be closed at time td. If the output signal of a current detector 6 contains higher harmonic components and its phase is not kept constant during a definite period at that time, a logic circuit 13 outputs a signal to a switch drive circuit 15 so that the switch 14 is opened at time Tb.

Title: Satellite broadcast receiver
Inventor: SAEKI HIROAKI
IPC: H04N5/445
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent a program having been selected early from being suddenly interrupted by comparing transmission channels of programs selected before and after and displaying a warning message when they are different. SOLUTION: Program information and transmission information are received simultaneously with video audio information and stored in a RAM 5. When a view instruction is made for a specific program from a user, a control section 10 decides a transmission channel from transmission information and gives an instruction to a tuner 2 for viewing. In this case, the control section 10 stores the selected number to a number memory 11. In this state, when a 2nd program instruction is made by an instruction section 9, the control section 10 reads a program number stored in the memory 11 and compares and decides the channel during reception from the transmission information in the RAM 5 and a transmission channel of a 2nd selection program, As a result, when they are equal, the reception instruction of a 2nd program is made to a separator section 4.  When different, a warning message is outputted to an OSD section 7 and a synthesis section 8 synthesizes the message with the video signal and displays the synthesized signal. When a continue instruction is made, the reception frequency of the 2nd program is read out of the RAM 5 to switch the reception channel.

Title: Post-processing method for printed circuit board fixing pin
Inventor: SUMIYOSHI HIDEYUKI
IPC: B23Q3/06
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent layered products from being separated scatteringly by machining a hole, the axis of which is parallel to the axis of a fixing pin and the diameter of which is smaller than the shaft diameter of the fixing pin in the inside of the fixing pin to lessen the fixing force of the fixing pin after the end of perforating a printed circuit board. SOLUTION: After the end of perforating work for fixing electronic parts to a layered product, a hole with a diameter(d) is bored in the axis of a pin 24. When a hole 26 is machined in the pin 24, the radial rigidity of the pin 24 is lowered. Accordingly, when the diameter of the pin 24 before press-in and the diameter(d) of a hole 25 of a laminated board are suitably selected, the diameter of the hole 25 is returned to the diameter D1 by machining the hole 26, so that the pin 24 can be engaged with the hole 25 by frictional force based on the elastic energy of the pin 24. The pin 24 having moderate rigidity left prevents a layered product from being separated scatteringly, so that the layered product where perforating is ended can be easily recovered automatically.
