Title: Engine piston
Inventor: ARIFUKU TAKATOMO
IPC: F02B23/06
Filed: 1989-03-06
Abstract: PURPOSE:To reduce waxy white smoke and irritating odor even in low temperature and low load driving by forming a conical projection in the base and a lip in an opening edge, respectively, in a cavity whose horizontal section is a regular pentagon. CONSTITUTION:A horizontal section of a cavity 2 installed in a piston top face 26 is formed into a regular pentagon, making up a corner which feeds a fuel spray from the central side. Then, a side wall 5 of this cavity 2 inclusive of the corner is set to an almost right angle to a fuel spray line. In addition, a conical projection 13 is formed on a bottom surface 11 of the cavity 2 and a lip 6 in an opening edge, respectively. With this formation, a relatively rich content air-fuel mixture exists in each corner, and thereby a diffusion air-fuel mixture of density suitable for flame propagation comes to exist in a swirl turning part 24. Thus, a combustion condition in the cavity 2 at time of low speed and light load driving is improved, thus discharge of hydrocarbon is reduced.

Inventor: IMAMURA YOSHINOBU
IPC: G05D1/02
Filed: 1980-04-18
Abstract: PURPOSE:To give control to the travelling of an unmanned carrier car with a simple constitution, by providing an inductor by leaving a prescribed distance from the track to detect the distance to the track and then detecting a traveling shift of the carrier car by an increment or decrement of electric signals to perform an automatic steering. CONSTITUTION:The track detector 1 of an unmanned carrier car consists of the inductor S1, oscillator OSC1 and converter CV1 and used at a position where the track K is apart from the coil L1 at a prescribed distance and in the lateral direction. The detection current IS caused by the inductor S1 is proportional to a lateral shift and sent to the comparator D of controller 2 via the converter C1. The comparator D compares the output of the potentiometer POT which is driven by a steering driving motor and the output VCV of converter and then drives the motor M via the control circuit STG. Thus the traveling direction is controlled for an unmanned carrier car.

Title: Hydraulic brake device
Inventor: MIZUTANI KYOJI
IPC: B60T8/00
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To invariably exert a brake assist function at accurate timing by correcting a threshold value to a high value in response to an increase of the viscosity of a brake fluid with a threshold value correcting means. SOLUTION: The outside air temperature is detected based on the output signal of an outside air temperature sensor, and a threshold value αth for the starting reference of brake assist(BA) control is set based on the detected outside air temperature. When the master cylinder pressure PM/C detected based on the output signal of a hydraulic sensor 22 is the threshold value αth or above, for example, an emergency brake action is detected, and BA control is implemented. The wheel cylinder pressures PW/C of wheel cylinders 38, 40 are quickly boosted to a liquid pressure higher than the master cylinder pressure PM/C in this case.  A braking force larger than the normal braking force is applied to wheels RR, FL as a result, thereby such a situation can be prevented that BA control is implemented unnecessarily when a brake pedal 10 is operated at a normal speed at a low temperature, for example.
