Abstract: PURPOSE:To evaluate the adhesive strength of the hard coating film of a coated product, that is, a coated cutting tool or a coated wear resistant member by directly detecting presence of the exfoliation of the coating film. CONSTITUTION:A body vibrating at 10Hz to 1kHz is brought into contact with the surface of a member coated with a hard coating film, the member is immersed in a liq. contg. powder, steel balls or ceramic balls having 150mum to 10mm average diameter and ultrasonic vibration is applied, or the member is put in a vibrating barrel together with steel balls or ceramic balls having 0.6-10 mm average diameter. Thus, presence of the exfoliation of the coating film is detected.

Thus, the ignitability at the time of low load is improved, favorable driving by a thin mixed gas is effected, and the economy of fuel cost is improved. At the time of high load a large amount of a mixed gas is supplied to improve the output performance. Adjacent to the control opening of the ON-OFF valve 17, the communication passage 16 is provided for communicating the auxiliary suction port 11 with the main suction port 10, so that the fuel is prevented from dwelling in the auxiliary suction port 11, and therefore the exhaust gas is purified.

Title: Valve timing controller of engine
Inventor: TANAKA KENICHIRO
IPC: F02D13/02
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a valve timing controller of an engine that is designed so as to make good drivability securable by avoiding any stepwise phase alteration in time of the alteration of gentle throttle opening as securing the alterative operation of a turning angular phase at high responsiveness. SOLUTION: In time of a sudden adjustable speed when a variation in actual turning angular phase is more than the set variation, a phase holding means 14 is operated at a point of time when a deviation between target turning angular phase and this actual turning angular phase has converged within the preset specified range and thereby a phase holding is carried out, so that such a phase alteration as being good in responsiveness is thus realized. Likewise, in time of a gentle adjustable speed when the viriation in the actual turning angular phase is less than the set variation, if the deviation between the target turning angular phase and the actual turning angular phase is converged withing the specified range, any operation of the phase holding means 14 is prohibited.  Therefore, the phase holding by this phase holding means 14 is not carried out, such a fact that a phase altering characteristic comes to be stepwise is surely checked at the time of gentle adjustable speed although the phase holding means 14 has high responsiveness, whereby good drivability is thus secured.

Title: Shoulder pad for shoulder bag
Inventor: MORIYAMA AKIRA
IPC: A45C13/30
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent a shoulder pad from slipping off the shoulder when the bag with a belt is hung on the shoulder for walking, by placing a pad for slipproof facility on a part of the shoulder of a belt of a shoulder bag, etc., and adhering a cloth for slip prevention on the bottom face of the pad. SOLUTION: This pad 2 is placed under a belt 1, and a cloth 3 is adhered on the bottom face of the pad 2. Since the pad 2 is subjected to vertical load against the slope of the shoulder 4, a gap is produced on one end of the touching face between the belt 2 and the shoulder 4, so to increase the touching area, a shoulder pad 2 is placed under the belt 1. The pad 2 has a cross section whose upper face to touch with the belt is horizontal and the bottom face to touch with the shoulder has a slope and, further, slipproof cloth 3 is adhered on the bottom face. Since the touching area is increased and friction is reinforced by the pad 2, the slipproof effect is generated. The belt and the pad are fixed by preliminarily inserting the belt through the pad.

Title: Formation of alloy layer in manufacture of superconductive element
Inventor: ISHIDA ICHIROU
IPC: H01L39/24
Filed: 1983-10-11
Abstract: PURPOSE:To obtain an alloy layer made fine in the crystal grain size even by increase of the total film thickness with good reproducibility by repeating a plurality of times of the process of evaporating metals of alloy components and alloying them. CONSTITUTION:A resist mask 6 is applied on a substrate 5, and Au, Pb, and In are successively evaporated from respective crucibles. The Au is deposited to 2.3nm at 0.5Angstrom / sec, Pb to 80nm at 20Angstrom /sec, and In to 17.5nm at 5Angstrom /sec, with the substrate loaded to a water-cooled holder. After a series of evaporation, the elements are kept for several hours at room temperature and turned into an alloy, resulting in the formation of an electrode layer 7, when the average grain size of the alloy layer is 130nm. After successive evaporation under the same condition, an electrode 8 is formed by alloying under the same condition, when the grain diameter is nearly the same, and the electrode 7 has no increase in the grain size. The formation of an electrode 9 by lift-off causes the grain size to be reduced to 130nm in spite of a layer thickness of 200nm and then improves the resistance to heat cycle. In this manner, the crystal grain size of the alloy layer depends on the thickness of the first or second alloy film and can be determined independently of the total thickness (t), and can be made fine by a thick film; accordingly the film quality becomes uniform.

Filed: 1987-07-28
Abstract: A method is provided for producing a self-supporting ceramic body comprising a polycrystalline material comprised of the oxidation reaction product of a parent metal (10) and having therein one or more channels which inversely replicate the geometry of a configured fugitive metal (6). The method includes providing an assembly of the configured fugitive metal (6) and the parent metal (10), optionally including a bed of permeable filler (4), and heating the assembly to form a body of molten parent metal. The molten parent metal is oxidized under selected conditions to grow the polycrystalline material to engulf the configured fugitive metal (6) (and to infiltrate the filler (4), if the filler (4) is present) and to cause the fugitive metal (6) to disperse into the engulfing polycrystalline material thereby leaving behind as the one or more channels the space formerly occupied by the configured fugitive metal (6). The method provides self-supporting ceramic bodies having therein one or more channels inversely replicating the shape of the configured fugitive metal (6).

Filed: 1982-10-27
Abstract: PURPOSE:To shorten the time for setting location without impairing its precision by first increasing the number of command pulses, generating then the pulses having opposite polarities, and thereby reducing the accumulated reading of a reversible counter in a location control circuit. CONSTITUTION:An adding device 103 adds the contents of a reversible counter 101 to those of an accumulator 104 every time a pulse Pc' is emitted from an AND gate 103', which generates pulses Pc' at a certain frequency Fo, and the sum obtained is stored in the accumulator 104. The accumulator 104 then emits a carry-up pulse OP, and a synthesizer circuit 104' converts it into a command pulse CP. Every time a CLOCK pulse Pc is emitted, the reversible counter 101 subtracts its content by one, and the speed of the carry-up pulses OP placed out of the accumulator 104 reduces linearly, and the speed of command pulses CP becomes zero according to generation of carry-up pulse OP.
