Title: Path-guiding device
Inventor: KUROKAWA HISASHI
IPC: G06T1/00
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To perform detailed guiding even at a newly installed guide point by changing the details and timing of the guide according to a judgment result of whether a vehicle is in stop or not. SOLUTION: A position-calculating means 2 calculates a current position and judges whether a current position is between (i-1)th and ith guide points counting from a start point (i: a positive integer). Then, it is judged whether distance when driving to the ith guide point according to a driving path from the current position is equal to or more than a threshold or not. The threshold is set to a distance for starting guide before the guide point and no guide is made when the distance is not equal to or more than the threshold. A stop- judging means 11 judges whether a vehicle is in stop or not and returns to a threshold judgment during driving, and a guide timing determination means 5 starts a guide for the ith point using a guide transfer means 6. This method allows a more detailed guide even if guide points are close each other.

Filed: 1990-06-08
Abstract: PURPOSE:To enhance the efficiency of terminology explanation generation work by providing a terminology retrieval means which retrieves from a thesaurus by individual fields, which corresponds to the designated field, and a terminology explanation generating means which generates the explanation of an item which becomes the terminology designated in the thesaurus of the item becoming the retrieved term. CONSTITUTION:When a terminology item designation means 2 requires the explanation of the terminology a terminology item storage means 3 designating the item becoming the terminology while a document is inputted temporarily stores the item which becomes the designated terminology, and a terminology field designation means 4 designates the field of the item becoming the designated terminology. The terminology retrieval means 5 retrieves the item becoming the stored terminology from the thesaurus 6 by individual fields, which corresponds to the designated field. The terminology explanation generating means 7 generates the explanation of the item becoming the term designated in the term dictionary 6 of the item becoming the retrieved terminology. In such a case, it becomes unnecessary to generate the explanation of the terminology after the generation of the document since the explanation of the terminology is automatically generated only by designating the item becoming the terminology while the document is generated. Thus, terminology explanation generation work can efficiently be executed.

Title: Intermittent turning gear
Inventor: OOIDA MAKOTO
IPC: F16H27/04
Filed: 1981-09-26
Abstract: PURPOSE:To aim at converting continuous rotation of a driving shaft being attached to a planet gear into intermittent rotation of a sun gear, by attaching an arm to a planet gear shaft, while linking a free end of the said arm with a cam groove made up on a fixed cam plate. CONSTITUTION:In the case where a pin center 36 or the tip of an arm 3' is in a circular motion at constant rotational frequency, if an end roller center 67 of an arm 6' attached to the pin center 36 moves along a closed curve 62, torque is not transmitted to a driven shaft 2 which is therefore stopped as these centers 36 and 37 both exist in a concentric part of a circle 32 out of the curve 62 and said circle 32. But when they are in other parts, some resistance acts on a planet gear 4, rotating the driven shaft 2, so that continuous rotation of the driving  shaft 1 can be converted into intermittent rotation of the driven shaft 2.

IPC: H01L21/302
Filed: 1986-06-30
Abstract: PURPOSE:To improve the dry-etching resistance of a photoresist, and to enhance an etching selection ratio of a substance to be etched to the resist, by arranging a substance consuming active radicals or ions in plasma which act as etching species to the resist on the substance to be etched on the surface of a wafer stage. CONSTITUTION:A base plate 17 consisting of single-crystal silicon is provided on the surface of an indentation section in a wafer stage 15 of a dry etching device. Other sections of the wafer stage 15 are constituted of quartz. When CF<+>3 impinges on an unpatterned SiO2 film area of a ferrite substrate 16, a chemical reaction occurs to remove the SiO2 film while producing SiF4 which take the form of gas at room temperature. Fluorine radicals F* generated in plasma in the same manner as CF<+>3 react with single-crystal silicon forming the base plate 17 and generated SiF4, and are consumed completely by the base plate 17. Accordingly, F* etching a resist is minimized only by the consuming section of F*, thus effectively reducing resist etching by F*.
