Title: Shit operation device for working vehicle
Inventor: SATO SHIGEO
IPC: F16H61/18
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To stably maintain a posture o a driver allowing shift operation to the acceleration side and prohibiting shift operation to the deceleration side in an auxiliary shift device when a detected traveling speed is higher than a set speed in a working vehicle provided with a main shift device and the auxiliary shift device. SOLUTION: A controller H using a microcomputer is arranged so as to input information from an auxiliary shift switch 32, a vehicle speed sensor S2 and the like. Using the controller H, a shift operation preventing means 100, which prevents shift operation of an auxiliary shift device S to the speed reduction side on the basis of the information from the vehicle speed sensor S2 when a traveling speed is higher than a set speed, is constructed. In concrete, a vehicle speed is detected by means of the vehicle speed sensor S2, and shift operation to the low/high speed side is carried out when the detected speed is lower than the set speed. On the other hand, if the detected speed is higher than the set speed, no shift operation is carried out if a low speed is commanded on the basis of the condition of the auxiliary shift switch 32, so that stability of drivers posture can be maintained.

Title: Rotor for brushless motor and brushless motor
Inventor: NAKAZAWA FUMIKIYO
IPC: H02K1/27
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To suppress motor noise and improve the rotational efficiency of a motor by covering with end plate members the opening ends of through-holes formed by stacking holes provided in iron core plates. SOLUTION: A laminated iron core 31 of a rotor for a brushless motor is formed by a plurality of stacked, disk-shaped iron core plates 37 and iron core plates 43, 44, and an output shaft 30 is made to pass through in the center of the laminated iron core 31. Iron core plates 43, 44 having no circular opening are provided to seal a through-hole 42. By enclosing the through-hole 42 with the iron core plates 43, 44, air inside the through-hole 42 is prevented from being disturbed by a centrifugal force that occurs, when a rotor 15 is rotated. Consequently, the rotational noise of the rotor 15 can be suppressed. Also since the disturbance of air around the laminated iron core 31 can be reduced, air resistance which the rotor 14 receives when rotating can be decreased.

IPC: B29C48/05
Filed: 1991-07-26
Abstract: PURPOSE: To obtain the long continuous object for an optical fiber, etc., at economical production rate by injecting and polymerizing a liquid monomer in a sheath at or immediately after the die opening while continuously extruding the sheath material. CONSTITUTION: This sheath material is supplied as a first component to an extruder provided with a circle extrusion die using the standard extrusion head for producing bi-component fibers of the center coating core(C/C) type and extruded continuously to form hollow fibers. The liquid monomer of an epoxy acrylate resin with an UV initiating agent, etc., contained is injected as a second component at or immediately after the die opening to form cores. The fibers thus obtained are passed through an UV irradiating device to polymerize and cure the liquid monomer in the sheaths, which then are wound at the same speed as the extrusion speed. Accordingly the long, of substantially unlimited length, thermosetting polymer continuous object of the C/C type is obtained at the economically allowable production rate.

Title: Polyamide resin composition
Inventor: KITANO YOSHITADA
IPC: C08K5/09
Filed: 1990-07-17
Abstract: PURPOSE:To prepare the title compsn. having a melt viscosity easily controllable during molding by melt mixing a polyamide resin with a small amt. of a carboxylic acid. CONSTITUTION:100 pts.wt. polyamide resin (e.g. nylon 6, nylon 66, nylon 11, or nylon 12) is melt mixed with a carboxylic acid (e.g. succinic acid, sebacic acid, or terephthalic acid) by a conventional method on, e.g. a twin--screw extruder. Thus the mol. wt. can be reduced without degrading the quality of the polyamide resin, leading to a reduction in the melt viscosity. Changing the amt. of the acid mixed enables a desired melt viscosity to be obtained; if the amt. of the polyamide resin is fixed, the melt flow rate can be arbitrarily controlled by changing the molar amt. of the acid, facilitating the molding, e.g. injection molding, of the compsn.

Filed: 1981-11-20
Abstract: PURPOSE:To perform high-speed, high-precision metering by forming an endless conveyor belt of numbers of article supporting bases divided in its moving direction at prescribed article supporting intervals. CONSTITUTION:When an article supporting base 2a supporting an article passes above a metering table, its porjecting body 21a runs onto a corresponding metering table 24a, and the total weight of the article supporting base 2a and the article on it is applied. Therefore, while the article supporting base 2a passes over the metering table 24a, the weight of the article is detected on the basis of a prescribed metering signal. A succeeding article supporting base 2b holding another article is also carried so that its projecting body 21b runs onto a corresponding metering table 24b, and the article weight is detected similarly. In this case, as the preceding supporting base 2a almost leaves the metering table 24a, the succeeding supporting base 2a starts moving onto the metering table 24a. Succeeding article supporting bases 2b and 2c are also carried similarly to detect the weights of their articles as well.

Title: Detecting circuit for trouble of rectifying diode
Inventor: ARAI YASUHIRO
IPC: H02M1/00
Filed: 1980-12-29
Abstract: PURPOSE:To detect the trouble of a diode by detecting the amplitude and period of the ripple component of the output of a rectifying circuit by means of the detecting circuit consisting of a differentiation circuit. CONSTITUTION:The output (1) of the rectifying circuit REC is supplied to the differentiation circuits CC, RC and output (2) is obtained. When the diode of the rectifying circuit REC is normal, the charging voltage of a capacitor C0 reaches only reference voltage VSID or lower because a transistor Q1 is conducted, and trouble signals are not outputted. When the diode gets trouble, on the other hand, the transistor Q1 is not conducted during the rectifying period of the trouble diode because there is no output from the differentiation circuits CC, RC during that period, the charging voltage (3) of the capacitor C0 increases, and trouble signals (4) are outputted from an output terminal.
