Filed: 1989-11-30
Abstract: PURPOSE:To easily correct the warpage of a resin product by molding the resin product using a mold consisting of a pair of retaining molds preset to different temps. on the basis of the warpage direction of the resin product after molding and crystallizing the low crystallized part in contact with the retaining mold on a low temp. side of the obtained resin product by annealing treatment. CONSTITUTION:In a resin product S after molding, the low crystallized part S1 not advanced in crystallization in contact with the retaining mold 2 on a low temp. side constituting a mold 1 and the high crystallized part S2 advanced in crystallization in contact with the retaining mold 3 on a high temp. side are generated. At this time, since wall thickness is non-uniform or a planar shape is assymmetric, the resin product S immediately after molding is warped in such a state that the low crystallized part S1 protrudes. When this resin product S is continuously subjected to annealing treatment, that is, heated at 130-150 deg.C for 3-4hr, the crystallization in the low crystallized part S1 of the resin product S advances and the length of the low crystallized part S1 largely contracts corresponding to the advance degree of the crystallization and warpage is corrected.

Inventor: ASHIZAWA TADAO
IPC: B21B37/54
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To resolve a problem in prior arts of damages and line stops of line material in the protection function which stop the electromotors suddenly through the overload state detection of the electromotors by each driver wherein many line materials are driven with the electromotors of a stand and each electromotor is controlled to line speed by the independent drivers.

Title: Double row roller bearing device
Inventor: MATSUI MASAHITO
IPC: F16C33/60
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent generation of creep at a fitting surface of an inner ring and a shaft by engaging a projecting part provided on a side of one inner ring with a recessed part provided in a side of the other inner ring. SOLUTION: In a double row angular ball bearing, a plurality of same rectangular recessed parts 4a are provided in a side of one inner ring 4 with intervals in the circumferential direction. A plurality of same rectangular projecting parts 4b are provided on a side of the other inner ring 4 with interval in the circumferential direction, and engaged with the recessed parts 4a in the side of one inner ring. When a large load in the radial direction is applied to one inner ring 4, the inner ring 4 to which the load is applied slides on a shaft 5 in the circumferential direction. However both inner rings 4 are engaged due to rugged parts of the side of the inner ring 4, and the relative rotation in the circumferential direction of both inner rings 4 to the shaft 5 is prevented, and both inner rings are integratedly rotated.  As a result, generation of a creep causing a problem on the bearing performance can be suppressed, and the service life of the bearing can be improved.

Title: Mask blank and production of mask
Inventor: HIEDA KATSUHIKO
IPC: G03F1/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of variation in the film thickness of a resist applied on a mask blank and to improve the precision of pattern dimensions. SOLUTION: On the whole of one surface of circular quartz-made substrate 12, a light shielding Cr-made film 13 is formed. A resist is applied on the light shielding film 13 while spinning the substrate 12. Since the substrate 12 is circular, the resist spreads on the entire surface of the film 13 in a uniform film thickness by centrifugal force. The applied resist is patterned to form a resist pattern and the light shielding film 13 is etched using the resist pattern as a mask. Thereby, a pattern of good dimensional precision can be formed.

The user can leave from a general ticket examination port by the returned admission ticket.  When the original ticket (train ticket and the like) is returned to the user at the time of issuing the admission ticket, and the original ticket is requested in addition to the admission ticket and the leaving is permitted with the supply as a condition. Thus, leaving with the admission ticket which is illegally obtained can be inhibited.

Title: Inductance circuit and switching power source using the same
Inventor: ISHII TAKUYA
IPC: H02M3/28
Filed: 1989-12-01
Abstract: PURPOSE:To efficiently detect a current by subtracting an induced voltage generated in an auxiliary winding from a voltage generated between windings of a main winding in which the current flows. CONSTITUTION:When a current (i) flows from a terminal 1 to a terminal 2, a voltage proportional to the time differentiation of the current is generated at both ends of a main winding 3 by the inductance L of the winding 3, and a voltage added with a voltage drop due to the winding resistance R of the winding 3 is generated. On the other hand, a voltage equal to the voltage generated by the inductance L of the winding 3 is induced in an auxiliary winding 4. The winding 4 has a winding resistance (r), but if the input impedance of a detector 5 is sufficiently higher, almost no current flows to the winding 4. Accordingly, the voltage V input to the detector 5 becomes V=V12- V15=R.i, and a voltage proportional to the current (i) is input to the detector 5.

Title: Production of acyl group-substituted aromatic compound
Inventor: MORIMOTO MASAO
IPC: B01J29/70
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To produce an acyl group-substituted aromatic compound by reacting an aromatic compound with carboxylic acids in the presence of a zeolite catalyst treated with ethylenediaminetetraacetic acids. SOLUTION: An aromatic compound (e.g. ethylbenzene) is reacted with a carboxylic acid or its derivative (e.g. propionic acid) which is an acylating agent in the presence of a catalyst, as necessary, in a solvent (e.g. cyclohexane) at 200-500 deg.C for 0.1-24hr. A catalyst prepared by slowly bringing ethylenediaminetetraacetatic acid or its salt as a treating agent into contact with zeolite with, e.g. a Soxhlet extractor is used as the catalyst. The decreasing rate of acylating yield with time found at the time of carrying out acylating reaction can remarkably be reduced by using the resultant catalyst.

Title: Fuel shutoff device
Inventor: NANO YOSHIHIRO
IPC: B60K15/01
Filed: 1992-10-28
Abstract: PURPOSE:To correctly regulate the quantity of fuel vapor emitted to the atmosphere by adjusting the internal pressure of a fuel tank correctly to designated pressure determined by a diaphragm valve when a fuel does not flow out from a fuel shutoff device to an external device such as a canister or the like. CONSTITUTION:When the internal pressure of a fuel tank is increased in the condition where a fuel does not flow into a lower space 26 such as the time a vehicle stops, the pressure in an inner chamber 42 is also increased. When the internal pressure of the fuel tank is increased to the balanced internal pressure of a positive pressure valve mechanism 30, the pressure in the inner chamber 42 is also increased to the balanced internal pressure. Accordingly, a diaphragm 33 is pushed up against the energizing force of a spring 31 and the atmospheric pressure, the positive pressure valve mechanism 30 is opened. Accordingly, the fuel vapor which has flowed in the lower space 26 flows to the canister side through the positive pressure valve mechanism 30 and a ventilation port 18 so that the internal pressure of the fuel tank is lowered. After that, when the internal pressure of the fuel tank matches the balanced internal pressure, the diaphragm 33 is restored to its initial form so that the positive pressure valve mechanism 30 is closed.
