Title: Disk medium
Inventor: HOSOKAWA TETSUO
IPC: G11B11/105
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To enhance an adhesion property of an NiP layer and to strengthen the NiP layer against an impact by film-forming the NiP layer by sputtering specifying the thickness at a specified temperature of a substrate to a specified range. SOLUTION: A magnetic disk is constituted of a magnetic layer 5 provided on a non-magnetic substrate 1 via a substrate 4. Here, the substrate 4 interposed between the non-magnetic substrate 1 and the magnetic layer 5 consists of a Cr adhesive layer 6 adjacent to the substrate 1 and containing Cr, an NiP layer 2 film-formed on the Cr adhesive layer 6 by sputtering and a Cr substrate 3 formed on the NiP layer 2. When the temperature of the substrate and the thickness of the NiP layer 2 are T( deg.C) and (t) nm respectively, a boarder line between combinations of high and low adhesion properties can be approximately expressed by the formula: T=-t+370 in a 40-200 nm range of the thickness of the NiP layer 2. A region where the high adhesion property can be obtained is the region which is located below the boarder line and satisfies the formula T<=-t+370.  I.e., the relation: T+t<=370 is formed.

Title: Vacuum cleaner
Inventor: NAKAO HIROSHI
IPC: A47L9/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent heat retaining in a cord reel chamber, and improve cooling efficiency by forming a cord outlet in a part of the cord reel chamber, and arranging an exhaust hole in a side surface upper part of the cord reel chamber. SOLUTION: When a vacuum cleaner is operated, exhaust air of a motor- driven air blower 6 is exhausted outside a cleaner main body for an exhaust port 11 after being purified mainly by an exhaust air filter 10. At this time, a part of the exhaust air of the motor-driven air blower 6 flows in a cord reel chamber 9 through a vent hole 12 arranged in a partition wall 21 or a clearance of the partition wall 21, and is exhausted from an exhaust hole 14 formed in a side surface upper part of a cord outlet 13 and the cord reel chamber 9 after cooling a cord 8. In this way, since the exhaust hole 14 exists in an upper part in which heat is easily retained, of heat retaining in the cord reel chamber 9 is prevented, and cooling efficiency is improved. Since the exhaust hole 14 of a cooling wind is kept away from a floor surface, whirling-up of dust of the floor surface by the exhaust air from the exhaust hole 14 can be reduced.

Title: Air-fuel ratio controller for engine
Inventor: KOMATSU KAZUYA
IPC: F02D41/14
Filed: 1985-09-10
Abstract: PURPOSE:To control the air-fuel ratio with high accuracy by constituting an oxygen sensor by using n-type and p-type metal oxide semiconductors and controlling the air-fuel ratio by the output value of the p-type having the superior responsiveness in the transition where the operation state varies. CONSTITUTION:An oxygen sensor 16 is constituted of the first and the second detecting pieces 21 and 22 consisting of n-type and p-type metal oxide semiconductors, and the active temperature is maintained by a heater 20, and the output values and synthetic values are outputted into a control unit 18. According to the characteristics of the sensor, the air-fuel ratio is controlled by the n-type output value when the air excessive rate lambda=1, and while by the synthetic value in the lean region where lambda>1, and by the p-type output value in the rich region where lambda<1. However, in the transition where the operation state varies, air-fuel ratio control is carried out by using the output value of the p-type detecting piece 22 preferentially, in consideration of the exceedingly superior responsiveness of the p-type. Therefore, even in the transition, air-fuel ratio can be finely controlled.

Title: Pressure sensor
Inventor: TSUNODA TERUO
IPC: G01L9/06
Filed: 1981-12-11
Abstract: PURPOSE:To detect the variation of pressure with no contact and continuously, by transferring the displacement of a bellows to the pressure sensitive rubber and converting to the variation of resistance value of said rubber. CONSTITUTION:A bellows 2 is expanded and contracted in accordance with the variation of pressure. When the pressure becomes high, the bellows pushes a holder 5 to the direction to which a spring 12 is contracted against the force of the spring 12. An elastic substance 6 and pressure sensitive rubber 9 are compressed by the force. When the rubber 9 is compressed, the inner resistance becomes small and the resistance between lead wires (a), (b) is decreased. When  the pressure becomes low and the bellows 2 is contracted, the compressing force  of the rubber 9 is reduced and the inner resistance becomes large and the resistance value between the lead wires (a), (b) is increased.

Filed: 1981-12-09
Abstract: PURPOSE:To reduce the area of chip by reducing the number of element to be used and improve the operating speed, by connecting MOS elements to be used for a CMOSRAM under a prescribed condition. CONSTITUTION:A chip select terminal CS is set to the high level and an NMOS Q17 is turned ON. When a signal BIT becomes lower than the threshold value  of a PMOS Q1 when the signal BIT read out from an ROM changes from the  ''H'' to ''L'', the PMOS Q11 is turned OFF. On the other hand, when the signal  BIT changes from the ''L'' to the ''H'', a PMOS Q12 is set to the OFF and an  NMOS Q16 is set to the ON, and a node N12 becomes the ''L''. The signal ''L''  is impressed upon the gate electrode of a PMOS Q13, the drain electrode of the PMOS Q13 rapidly becomes ''L'', an output terminal OUT1 rapidly becomes ''H'',  and another output terminal OUT2 rapidly becomes ''L''. Therefore, the sense  time from the starting of the change of the signal BIT till the output terminal  OUT1 becomes ''H'' can be reduced.
