Title: Magnetic recording device
Inventor: ITOU NORIO
IPC: G11B21/12
Filed: 1983-02-03
Abstract: PURPOSE:To save electric power and solve the problem of heat generation by using a self-holding type solenoid which is only fed with an instantaneous current at head loading, i.e. at attraction and return and requires no holding current. CONSTITUTION:The solenoid has a compression coiled spring 10 which generates restoring force and a permanent magnet 5 at the front part. A figure (a) shows a state before an attracting coil 1 is conducted. When the gap 13 between a movable iron core 3 and a fixed receptacle 9 is set larger than the gap 12 between the movable iron core 3 and a yoke 7, almost no attracting force is generated at the gap 13 by the magnetic force of the permanent magnet 5. A figure (b) shows an conductive state and the magnetic flux by the coil 1 is opposite to the magnetic flux of the permanent magnet 5 at the gap 12, so that all pieces of magnetic flux are attracted by the fixed receptacle 9. A figure (c) shows the nonconductive state of the coil 1 after the movable iron core 3 is attracted to the fixed receptacle 9 and the gap 13 at this time is zero, so the movable iron core 3 and fixed receptacle 9 are attracted continuously by the magnetic flux of the permanent magnet 5. A figure (d) shows a state when the conductive direction is made opposite, and the iron cre returns to its original position by the compressed coiled spring 10.

Title: Decoder
Inventor: MIYASAKA SHUJI
IPC: G10L19/02
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To precisely calculate x (4/3)*2 (y/4) by the processing of a fixed decimal point format even when the value of an integer X is sufficiently smaller than the maximum value of its varying area. SOLUTION: A separation means 100 separates a quantization signal (x) and a scale factor (y) from an input bit stream. A deciding means 101 decides whether the output quantization signal (x) of the means 100 is smaller than 2 N or not with an integer N as a set threshold value. The means 101 outputs a deciding result by deciding (x) to be true when it is smaller than 2 N but deciding (x) to be false when it exceeds 2 N. A storing means 102 stores the integer value (q) of 0 to (2 Q-1) by the fixed decimal point format according to q (a/b) in setting Q to be an integer. In setting an integer, which the arithmetic value y2 of a remainder calculation means 105 can range, to be (p), a storing means 103 holds the value of 2 (p/c) as G (P) with respect to P of 0 to 3 to store by the fixed decimal point format. F (x) and G (y2) read from each storing means are multiplied 106.

Abstract: PURPOSE:To uniformize variation of ventilating drag which is local and periodic in a circumferential direction at the time of rotation of a cooling fan so as to aim at making noise low by forming communicating holes on shielding plates which close release parts that are formed to extruding parts from a heat exchanging part of a fan opening so as to allow air to flow in. CONSTITUTION:In a fan shroud 1, a cooling fan 6 is provided to a fan opening 5 which is formed on a covering plate 4 that covers a heat exchanging part 3 of a heat exchanger 2, while a cylinder part 8 which surrounds an outer periphery of rotary vanes 7 of the cooling fan 6 is equipped. In this case, upper and lower extruding parts (release parts 9) from the heat exchanging part 3 of the fan opening 5, where the size of part of the rotary vanes 7 doesn't correspond with the size of the heat exchanging part 3, are closed by shielding plates 10 on which plural communicating holes 11 are formed. Thereby, such phenomenon that ventulating drag periodically varies is prevented, which is caused because the rotary vanes 7 alternately pass the heat exchanging part 3 and the parts closed by the shielding plates 10 at the time of rotation of the cooling fan 6, so that making noise low can be aimed at.
