Title: Production of sand mold for casting
Inventor: YAMADA SHIYOUJI
IPC: B22C9/02
Filed: 1982-12-28
Abstract: PURPOSE:To use a binder without considering the seasonal difference in atm. temp. and to eliminate inconvenience by packing the self-curable molding sand which is added with a binder and is kneaded in a pattern for a casting, heating the same to a room temp. or above and curing the sand thereby forming the sand mold. CONSTITUTION:The process from kneading up to sand blowing is basically the same as in the prior art but the time for curing is extremely shorter than the case of curing the sand at a room temp. as in the prior art and the time for an operation cycle is decreased considerably. If therefore the binder which does not cure in a short time at room temp. is used, the kneading of the sand is accomplished thoroughly with the stable operation, whereby the sticking and curing of the sand in a kneading machine are obviated and the continuous molding operation is not hindered.

Abstract: PURPOSE:To easily evaluate the optical performance of an optical beam with high accuracy by providing two optical paths of a regular optical path for leading the optical beam from a light source to a photosensitive body surface and a beam diameter adjusting optical path as a straight optical path, so as to change over them. CONSTITUTION:In the normal states of when a copying device is shipped, when it is used for coping, etc., an optical beam 1 finished to pass through an image forming optical system 3, is reflected by a first mirror 4, and passes a regular optical beam outgoing port 9 provided on a case 80, through reflecting mirrors 5, 6, etc., to form the regular optical path 1A to the photosensitive body surface. On the other hand, for obtaining an optical beam for adjusting, the beam diameter adjusting optical path 1B is formed in such a manner that when the mirror 4 rotatively provided is turned, the optical beam 1 finished to pass the image forming optical system 3 comes out therefrom, and travels straight, as it is, without being reflected by the mirror 4. Thus, an exclusive optical path corresponding to the evaluation of the optical performance, can be easily obtained separately from the regular optical path for writing.

Title: Control method of preventing slip of power train
Inventor: HOSAKA AKIO
IPC: B60K28/16
Filed: 1983-12-14
Abstract: PURPOSE:To surely prevent slip, by detecting two kinds of speeds in accordance with the degree of a slip which takes place, and as well by reducing the output torque of a power train to make the difference between these speeds zero. CONSTITUTION:In accordance with the values VL, VR of left and right rear wheel speed signals 142, 143 which are stored in a RAM1430 by means of an input interface circuit 1200, a CPU1300 computes the ratio of VR/VL, and judges that a slip takes place, when this ratio is out of a predetermined range of reference value. Then the CPU calculates a slip rate S(S=1-VR/VL), and differentiates the slip rate to obtain the differential value D of the slip rate after the differentiated value of the slip rate is multiplied by a constant K1. Further, this differential value D is added with the product of the slip rate S and a constant K2 to obtain a torque compensating value T. Further, the CPU calculates a throttle valve opening degree compensating value (f) which corresponds to the compensating value T, and issues an air-amount control signal 220 corresponding to this compensating value (f).
