Title: Magnetic recording and reproducing head
Inventor: MATSUDA NOBUHIDE
IPC: G11B5/187
Filed: 1983-06-02
Abstract: PURPOSE:To prevent the tip part of a main magnetic pole from wearing down to improve the recording and reproducing characteristics by making the sectional area of the face, which is brought into contact with a recording medium, of the main magnetic pole smaller than that of an auxiliary magnetic pole. CONSTITUTION:The sectional area of a tip part 8 of a main magnetic pole 2 is made smaller than that of a tip part 7 of an auxiliary magnetic pole 1. Therefore, though the tip part of the main magnetic pole 2 wears down when a medium 3 and the main magnetic pole 2 are moved while being brought into contact with each other, a recess is not generated because the tip part of the main magnetic pole 2 is pressed by the auxiliary magnetic pole 1 having a larger sectional area and wears always; and consequently, the recording and reproducing characteristics is not degraded even if the magnetic head is used for a long time.

Title: Electron beam exposure device
Inventor: SAITOU NORIO
IPC: H01J37/305
Filed: 1984-05-18
Abstract: PURPOSE:To curtail sharply settling time, and to make an electron beam exposure device to enable to perform high speed action by a method wherein the dot smeared away region of a smeared away field is deflected using a DAC of small bit number, and correction of delfection distortion of every dot is made unnecessarily. CONSTITUTION:Correction of deflection distortion is bestowed from a circuit 8 to every decomposed smeared away field, and correction of every dot is not performed at a dot decomposition circuit 11. Namely, the ratio of the bit number of a main deflection DAC9 and a smeared away deflection DAC13 is made sufficiently large, and correction of deflection distortion of every dot in the smeared away field can be made unnecessarily. For example, when the ratio of bit number of the main deflection DAC9 and the smeared away deflection DAC 13 is made to the degree of 2<10>, deflection distortion of the smeared away field becomes to the degree of 10<-3> of distortion of the field, correction of deflection distortion of every dot inside of the smeared away deflection DAC is unnecessary, DAC settling time becomes to 10ns or less, and to make exposure time to become to cirfcuit velocity controlling stage can be avoided.

Title: Die for coating
Inventor: MURATA NAOTO
IPC: B05C5/02
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent air bubbles from being admixed in a coating film by projecting the end part of a lower lip part more than that of an upper lip part in a die for coating wherein the end parts of the upper and the lower lip parts forming a slit-like coating jetting opening in the coating jetting direction are made to approximately the same projected length. SOLUTION: In a die coating method wherein a coating material is jetted from a jetting outlet 7 of a die 1 and the jetted coating material is transferred on a metal belt wound on a backing roll, the die is prepd. by joining an upper head member 4 and the lower head member 5 together and forming a manifold 6 and the jetting outlet 7 communicated therewith in both boundary parts. In this case, the end part of a lower lip part 9 in the jetting direction is projected more than that of an upper lip part 8 in the jetting direction. The lower lip part 9 can be approached to the metal belt just before it is brought into contact with the metal belt to obstruct the air flow generated by passing the metal belt through and air bubbles are hardly admixed thereby into a coating film and the coating material is prevented from sagging down from the lower lip part 9.

Title: Sintered zirconia material and its production
Inventor: ICHIMORI TERUMITSU
IPC: C04B35/48
Filed: 1993-04-26
Abstract: PURPOSE:To improve the strength and thermal shock resistance while keeping the characteristic breaking toughness of a CeO2-based ZrO2 by adding specific amounts of Al2O3, SiO2 and B203 to ZrO2 containing a specific amount of CeO2. CONSTITUTION:This zirconia-based sintered material contains a main component composed mainly of ZrO2 and 10-20mol% of CeO2 and a subsidiary component consisting of 0.1-10wt.% of Al2O3 and 0.05-0.5wt.% each of SiO2 and B2O3. The sintered product is produced by forming the raw material powder and sintering at 1400-1600 deg.C. When the CeO2 content is less than 10mol%, a stable ZrO2 cannot be obtained and crack is generated in the sintered product. The characteristic breaking toughness of the CeO2-based ZrO2 is unattainable at a CeO2 content of >20mol%. Al2O3 and SiO2 are effective for improving the strength and the effect is further promoted by the combined use of both components. The effect cannot be attained when the amount of each component is less than the respective lower limit. On the contrary, the addition of the component exceeding the upper limit causes the lowering of strength. B2O3 has an effect to improve the thermal shock resistance. It is necessary to add B2O3 in an amount exceeding the lower limit, however, strength is lowered when the amount exceeds the upper limit.

Abstract: PURPOSE:To prevent the occurrence of unstable transformation operation by locating a torque limiter to control surplus rotation of a rotary shaft after completion of transformation operation of a footstep between a rotary shaft and a sprocket and rotating the sprocket more than necessary through elongation of a chain for transmitting a power. CONSTITUTION:Elevating operation of footsteps 81-83 for a wheelchair is effected through rotation of rotary shafts 12 and 13. Sprockets 15 and 16 are mounted on the rotary shafts 12 and 13 through a torque limiter 14 and rotated in a reverse direction to each other by means of gears 17 and 18. Through elevation operation of a device 20, a chain 20e is moved to either the sprocket 15 or 16 for rotation.
