Title: Magnetic disk device
Inventor: SASAKI TOMOKO
IPC: G11B27/10
Filed: 1988-11-18
Abstract: PURPOSE:To obtain stable servo operation by converting plural binary codes to gray codes and recording the respective gray codes, for which circularity is kept, out of the gray codes to the prescribed position of respective storing parts in a magnetic disk as servo data. CONSTITUTION:Plural continuous binary codes BIN are converted to gray codes GRAY. Then, the code to include the prescribed bit string and the unsuitable code for keeping the circularity are removed out of these gray codes GRAY and the gray code GRAY, which is changed by only one bit between the adjacent codes, to keep the circularity is prepared. Next, the respective gray code GAR, for which the circularity is kept, to be obtained is recorded to the prescribed position of the respective storing areas in the magnetic disk as the servo data to show the physical position of the storing area. Accordingly, since the unsuitable bit string is not included in these servo data, the servo data are not erroneously detected as other recording information. Thus, the stable servo operation can be obtained.

Title: Copper alloy for lead frame superior in oxide film adhesion and manufacture thereof
Inventor: SATO TOSHIHIRO
IPC: H01L23/50
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics for lead frames and oxide film adhesion by preparing a Cu alloy composed of P, Co, Cu and inevitable impurities where the P to Co wt.% ratio is specified. SOLUTION: P is used as a molten metal deoxidizer and compounds with other element to produce a precipitate which improves the strength, heat resistance, etc., without deteriorating the electric-terminal conductivity and contained 0.001-0.25 wt.%. Co forms a dispersed and precipitated Co-P compd. with P to reduce the amt. of P solidified in a matrix, and to improve the oxide film adhesion, heat resistance, electrical conductivity and mechanical strength, and a total content of 0.01-0.50 wt.%. When a Co to P ratio is 1.5 or less, suppression effect of P segregation by Co cannot be expected, resulting in a larger reduction of the oxide film adhesion. Hence, this ratio is set to a range of 1.5-10.

Title: Estimation of size of integrated circuit
Inventor: YAMADA MASAAKI
IPC: H01L21/82
Filed: 1985-12-26
Abstract: PURPOSE:To estimate the height of the block simply and accurately by a method wherein, after the total number of the cell terminals and the number of the channel stages of the integrated circuit are set, the channel width of the integrated circuit is found by the channel width function. CONSTITUTION:A channel width 5 is decided according to the congestion degree of a wiring 7 in each channel and the congestion degree of the wiring depends on the number of pieces of terminals to be wired, that is, of terminals 6 facing the channel. If the terminals caused by passing wirings are ignored, the number of pieces of the terminals facing the channel is equal to the number divided the total number P of the cell terminals in the block by the number C of the channel stages. Accordingly, the number of pieces of the terminals facing one channel can be estimated by P/C. Here, if the function to find the channel width from the number of the terminals facing the channel is assumed to be (f), one channel width (h) is represented by the function h=f(P/C) of the P and C and the height of the whole of the channels can be estimated by Cf(P/C), while if the number of stages of the cell rows and the average height of the cells are each assumed to be (r) and (d), the height of the whole of the cell regions can be estimated by (r.d). Accordingly, the estimate formula of the height H of the block is represented by Formula I.

Title: Kerosene burner
Inventor: TOMITA HIDEO
IPC: F23D11/44
Filed: 1991-11-08
Abstract: PURPOSE:To prevent the splashing of kerosene from an inclined vaporization section and improve its vaporization capability by means of making the kerosene flow smoothly on the inclined vaporization section. CONSTITUTION:Diffusion grooves 22 are provided substantially in horizontal direction in an inclined vaporization section 19 except in a non-groove section 21. A fuel conveying nozzle 26 is provided so as to blow out the fuel towards the non-groove section 21. Since the kerosene blown out of the fuel conveying nozzle 26 obliquely collides with the non-groove section 21, the kerosene picks up a large amount of heat from the non-groove section as it spreads over the upper surface of the non-groove section 21 and the kerosene is rapidly vaporized. Namely, since the kerosene blown out of the fuel conveying nozzle 26 does not directly collide with the diffusion grooves 22, the kerosene does not fly back from the inclined vaporization section 19 as kerosene particles. After this, the rest of the kerosene flows into the diffusion grooves 22 and it is vaporized as it spreads in band shape over the surface of the inclined vaporization section 19 owing to the diffusion action of the diffusion grooves 22.

Title: Filter circuit of piezoelectric acceleration sensor
Inventor: NAKANO YASUYUKI
IPC: G01P15/09
Filed: 1994-11-28
Abstract: PURPOSE: To set a low band-shutting frequency low and reduce leak changes by equivalently connecting a capacitor in parallel to a static capacity of a piezoelectric element to increase the static capacity. CONSTITUTION: A capacitor 5 is equivalently connected, in parallel, to a static capacitance 1 of a piezoelectric element, so that the capacitance 1 is increased by the capacitor 5. In this case, a low band-shutting frequency determined by a load resistance 3 connected, in parallel, to the capacitor 5 and the capacitance 1 is smaller than a conventional low band-shutting frequency determined by a load resistance and a static capacitance. Since the low band-shutting frequency can be made small, the load resistance can be decreased and leak changes can be reduced.

Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a construction of a paint can, that allows a lid to be opened and closed even after paint has been used, and the paint to be used up to the last drop. SOLUTION: Several drain holes 3 are bored in the bottom 2 of a peripheral fitting groove around an opening of a paint can 1. Paint that flows onto the bottom 2 of the peripheral groove drips down form the drain holes 3 into the paint can 1. Therefore, the paint hardly gathers on the bottom 2 of the peripheral groove. A little amount of the paint remaining on the bottom 2 of the peripheral groove is pushed out from the drain holes 3 by air in the space in the peripheral groove when a lid 4 is closed.

Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a thermally-actuated switch used in a closed-type motor- driven compressor, easy to attach thereto, and high in reliability. SOLUTION: This thermally-actuated switch 21 is made up of a switch body 2 and an electrically insulating holder 23 for housing it. The switch body 2 is held apart from an inner wall of the holder 23 by protrusive ridge parts 23D 23E, and the holder 23 is provided with a plurality of opening parts 23A, thereby exposing the switch body 2 sufficiently to a flowing coolant gas. Fixed parts 23B extending from both ends of the holder 23 are fixed to a coil end 6A of a motor by binding them with strings 6B. The switch body 2 is insulated electrically and thermally from the coil end 5A by the holder 23, and cooled by the coolant gas under normal conditions. If coils of the motor are overheated the temperature of the coolant gas rises to lose its cooling effect, and the heat produced within the switch actuates the switch rapidly.
