Title: Cage for rolling bearing used for connecting rod of two--cycle engine
Inventor: MOTOHASHI NOBUTSUNA
IPC: F16C33/46
Filed: 1994-06-09
Abstract: PURPOSE:To provide a retainer which has the excellent lubricity and can prolong the seizure life. CONSTITUTION:Concerning a roller bearing 6 which is constituted by accommodating a plurality of needle-shaped rollers 62, ... in the pockets 63, ... formed at several places on the circumference of a retainer 61, a Ni-P plated layer 9 which is formed by dispersing a solid lubricant is formed on the surface of the retainer 61. Since the Ni-P plated layer 9 hardly reacts with the sulfur contained in the gasoline of the mixed gas of a two-cycle engine, the exfoliation of the Ni-P plated layer 9 from the surface of the retainer 61 is prevented. The self lubricity of the Ni-P plated layer 9 is developed over a long period.

Title: Laser oscillatory displacement measuring instrument
Inventor: FUJITA SUSUMU
IPC: G01H9/00
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To obtain a laser oscillatory displacement measuring instrument which can eliminate the difficulty of a high-accuracy measurement when an object to be measured is oscillated at low speed by a method wherein a circuit is constituted in such a way that an orthogonal demodulator, a position processing circuit and an addition circuit are installed. SOLUTION: A measuring instrument is constituted of a laser oscillation device 2, of a beam splitter 3, of an acousto-optical converter 4, of a beat- frequency oscillator 7 which drives the acousto-optical converter 4, of a photoelectric converter 6 and of a demodulation part. The demodulation part is constituted of an orthogonal demodulator 12 and of a phase processing circuit 13. The orthogonal demodulator 12 decomposes an amplified signal into orthogonal components by a synchronous detection. By the phase processing circuit 13, the orthogonal components which are output from the orthogonal demodulator 12 are converted into a displacement. Thereby, the displacement can be measured with high accuracy in a wide measuring-frequency band so as to include the extremely slow displacement of an object, to be measured, in a nearly stationary state, and the displacement can be measured over a wide measuring range.

IPC: B41M7/00
Filed: 1986-06-04
Abstract: PURPOSE:To easily discriminate at a look whether a print protective member has been used, by providing an indicative layer comprising a color forming or color-changeable substance on one side of a base. CONSTITUTION:When this print protective member is used for a lamination treatment, an indicative layer comprising a color forming or color-changeable substance provided on an exposed side of a base is caused to form a color or is changed in color due to a change to which it is subjected during the treatment, thereby functioning to indicate that the protective member is used for the lamination treatment. The change to which the indicative layer is subjected during the lamination treatment may be heating, application of pressure or the like for lamination, and a substance or composition capable of forming a color or undergoing a change in color when it is heated or a pressure is applied thereto is used as a material for forming the indicative layer. Since it can be discriminated at a look whether a given print protective member has been used for the lamination treatment, the yield in protection of prints is enhanced, and contamination of a laminating machine can be obviated.

Title: Diaphragm for electroacoustic transducer
Inventor: ONO YUJI
IPC: H04R7/02
Filed: 1992-04-20
Abstract: PURPOSE:To lower the density and also to keep the proper internal loss and rigidity for a diaphragm of an electroacoustic transducer by using the cellulose fibers extracted from the mantles of sea squirts and an inorganic material. CONSTITUTION:A diaphragm is made of the cellulose fibers extracted from the mantles of sea squirts and a fiber or impalpable powder type inorganic material. The extracted fine cellulose fibers are beaten up to the microfubrils and therefore the surfaces of these fibers are activated. Thus the cellulose fibers are combined with each other with the intensive hydrogen combination and also enclose the inorganic material. Then the rigidity of the diaphragm is improved by the synergism of both characteristics of the cellulose fibers and the inorganic material. The sea squirts live in 100 kinds or more, and at present the 'MABOYA' (a kind of sea squirt) are bred and easily available. Thus the Young's modulus (E) is extremely improved compared with the increase rate of the density (rho). Then the specific modulus of elasticity (E/rho) and the propagation velocity can be improved.

Title: Dead weight compensating system in measuring load on elevator suspending part
Inventor: ERITSUKU KEI JIEIMIISON
IPC: G01G19/14
Filed: 1993-05-31
Abstract: PURPOSE: To compensate a tare in the load measurement of the hitch of an elevator car and to compensate an elevator hitch load weighing system without using a correction weight. CONSTITUTION: In an elevator hitch load weighing mechanism, a load cell outputs an analog load signal to an adder 12. In the adder 12, an analog tare compensation signal is subtracted from the analog load signal before a compensation load signal is given to an analog/digital converter(ADC) 20. A digital load signal is given to a remaining tare subtracter 26, a tare left in the digital load signal is subtracted, and pay load is obtained. A dynamic tare is measured and it is used for recorrecting an elevator hitch load weighing system. An advantage is that the elevator system itself is used to correct the self-weighing system, since a correction weight for recorrecting the load weighing system is not required.

Abstract: PURPOSE:To provide a pairing mechanism in which air and water etc. can be applied as a lubricating agent, a universal operation can be performed, it is light in weight and occurs no creep phenomenon during its longer years use by a method wherein one or both of the two components constituting the pair are formed by molded ceramics. CONSTITUTION:A pairing mechanism A is composed of a guide element 1 and a guided element 2, and one or both of elements 1 and 2 are made such that alumina more than 80 part and clay less than 20 part are finely crushed, water of 20-30 part and peptization agent of 0.2-1 part are mixed therewith and peptized, and the muddy material is molded, then sintered at 1,550-1,700 deg.C. The surface is ground plainly with diamond. Such a pairing mechanism does not produce any stains or chemical variation even if water or air etc. are applied as a lubricating agent, and furthermore, the weight can be reduced, so that a moving inertia of the guided element is quite low and the rigidity is made high, resulting in that its operation is simple and a stationary position can be secured, no occurrence of creep phenomenon is found even in case of longer hour's use and accordingly this can be most suitable for the pairing mechanism for a precise measuring device.

Filed: 1992-05-21
Abstract: PURPOSE:To improve performance by replacing a first-order cache memory at high speed and preventing the first-order cache memory from generating any blank entry when the entry is replaced by cache error. CONSTITUTION:When the cache error is generated at a second-order cache memory 24 at the time of read access or write access from an operation processing part 22, the second-order cache memory 24 reports the address of the replaced entry to a first-order cache memory 23 before transferring data. When the entry corresponding to the replaced entry of the second-order cache memory 24 is existent, the first-order cache memory 23 defines the entry as the replace entry and when such an entry is not existent, the entry based on the priority order of replacement is defined as the replace entry. Thus, the first-order cache memory 23 can be replaced at high speed, and the blank entry can be prevented from being generated.
