IPC: B29C45/16
Filed: 1988-12-05
Abstract: PURPOSE:To obviate the unnecessity of after-treatment and to mold a large-sized product excellent in appearance regardless of the shape of the product by a method wherein a portion corresponding to the tick wall part ahead of the defroster part of an instrument panel is utilized as a runner and, further, portions corresponding to the defroster part as gates. CONSTITUTION:Resin is filled in a cavity 38. Concretely, after the tip of a pouring head 82 is fitted to a sprue 66, polyol and di-isocyanate are poured under the predetermined pressure from the pouring head 82. Said resin materials are filled through a runner 68 and gates 70 into a cavity 38. Accordingly, the foaming reaction of the polyol with the di-isocyanate proceeds under favorable condition in the cavity 38. Thin-walled parts 29, which corresponds to the gates 70 and are respectively provided among vent holes 28a-28d, are arranged evenly apart from and along its end edge part 24 in the nature of the function of the defroster part 30.

IPC: H02P8/00
Filed: 1988-12-05
Abstract: PURPOSE:To conduct control properly in consideration of all stepping-angle region of a stepping motor by obtaining the outputs of stepping of a position sensing means as learning values in response to at least the minimum and maximum stepping angles of the stepping motor. CONSTITUTION:An ECU 12 constituting a learning-value storage means, a detecting-value decision means, a drive control means and a learning value update means starts the angle of stepping of a stepping motor 3 in the '0' of the minimum, and reads the output of stepping of 0 corresponding to the angle of stepping of '0' from a position sensor 4. When the output of stepping of 0 is brought to a normal value smaller than a fixed value, the output of stepping of 0 is updated as a 0 stepping learning value and stored. The target number of stepping (n) is stepped up by one and the stepping motor 3 is operated at the angle of stepping of '1', and the output of stepping of 1 is read from the position sensor 4. When the output of stepping of 1 is brought to a normal value larger than the 0 stepping learning value, the output of stepping of 1 is updated as a 1 stepping learning value and stored.

IPC: F24F13/20
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To permit the treatment of condensate without reducing the changing amount of airflow direction upon cooling operation by a method wherein projections are provided on the end surface of downstream side of air of a mounting shaft of left and right flaps at the lower part of an air outlet grille at a distance, in which the projections will not be contacted with the lower part of the air outlet grille in the left and right movable range of the left and right flaps. SOLUTION: A projection 5 is provided on the end surface 4 of the downstream side of air of a mounting shaft 3 of a left and right flap 1 at the lower part of an air outlet grille 2. When the left and right flaps 1 are turned and disturbance is generated in the flow of air by the change of the same upon cooling operation, condensate is adhered to the surface of the left and right flaps 1. In this case, the condensate 6 flows toward the end face 4 by the attaching angle of the left and right flaps 1. Then, the condensate becomes the drops of condensate 6, which are bigger than the initial drops of the same, and are collected to the projection 5. A distance between the projection 5 and the lower part of the outlet grille 2 is set so as to be a distance wherein the condensate 6 flows quickly when it has come to the projection 5.  According to this method, the condensate 6 flows along the lower part of the air outlet grille 2 and is disposed into the dew treating groove 8 of a front frame 7 whereby the condensate 6 will not be dropped to the outside of the air conditioner.

Filed: 1989-11-30
Abstract: PURPOSE:To enhance spalling resistance by specifying the loadings and particle size of MgO.Al2O3-based spinal raw material and adding aluminous crushed particles at a specified amount. CONSTITUTION:As alumina/spinal-based casting material, a mixture is utilized which consists of by wt.% 10-82 alumina raw material, 10-70 MgO.Al2O3-based spinal raw material having >=0.3mm particle diameter and 8-20 alumina cement. Aluminous crushed particles having 10-50mm particle diameter are added to 100wt.% this mixture at 10-40wt.%. When fine powder having <=0.3mm particle diameter is added as the spinal raw material, the structure of the heated and unheated face sides of the worked body of casting material is made ununiform and becomes the cause of a crack and peeling. Further when the loadings of the spinal raw material are regulated to >=70%, it is added as fine powder and the above-mentioned structure is made ununiform. When the particle diameter and the loadings of the aluminous crushed particles are together made less than the lower limit, the effect for inhibiting the crack is lowered. When these exceed the upper limit, workability is lowered.

IPC: F16H1/32
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To increase destructive strength of a flexible external gear in a deflecting meshing type gear device. SOLUTION: An annular rigid internal gear 2 of a deflecting meshing type gear device, relating to a mounting surface of a device housing which is a fixed side member, is tightened by tightening bolts 5-1 to 5-5.

Title: Push-button dial signal receiving system
Inventor: HIROSE KAZUTO
IPC: H04Q1/45
Filed: 1989-11-30
Abstract: PURPOSE:To prevent the malfunction of a push-button dial signal receiver caused by a voice by constituting the above system so that each signal level is monitored, and reception and discrimination to a multi-frequency signal are not executed, when the level exceeds a prescribed signal level. CONSTITUTION:A limiter 30 is constituted so that any output is generated from the limiter even against a signal exceeding a prescribed dynamic range by a voice detecting circuit 40. That is, a frequency component 201 of a low group being an input signal is compared with a threshold from a setting device 402 by a comparator 401, by which when the input signal exceeds the threshold, the comparator 401 suppresses an output from the limiter 30 by its output. In such a way, when a large sound signal is inputted, even if a frequency of a push-button dial signal is contained in its component, the push-button dial signal receiver does not cause a malfunction by its sound signal.
