Title: Autonomous traveling method and autonomously traveling vehicle
Inventor: KUBOTA YOSUKE
IPC: A01B69/00
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent an accident from occurring by comparing positioning data with permission data and judging whether or not the position of an autonomously traveling vehicle at the point of time when the start of an autonomous travel is instructed is at a place where the autonomous travel can be started. SOLUTION: The point of time when automatic drive is started is specified as a reference point, whose position is set (S101). The current position of a working vehicle when a start switch is pressed is calculated by a D-GPS position detection part to obtain position measurement data indicating the current position of the working vehicle (S103). Two-dimensional difference data are found as (position measurement latitude-permission data latitude, position measurement longitude-permission data longitude) (S104) and two-dimensional difference data are converted into one dimensional data to find a value, which is compared with a threshold (S105). When this value is less than the threshold, it is judged that the position where the start of automatic drive is instructed is a regular position and the automatic drive is started (S106).  When the threshold is exceeded, on the other hand, it is judged that this position is not the regular position and the automatic drive is inhibited (S107).

Title: Heating method for metallic strip in oven of continuously-coating line
Inventor: ASAHINA HIDEYUKI
IPC: B05D3/02
Filed: 1989-08-17
Abstract: PURPOSE:To enhance efficiency and also to prevent generation of a flaw due to foams on a coated film by regulating the temp. wherein cross-linking reaction of resin for coating is started to the temp. below the prescribed temp. or more and regulating b.p. of a solvent to the temp. below the prescribed temp. and holding the resin at a time below the prescribed time. CONSTITUTION:In the heat pattern of rise in temp. of steel strip 8 in an oven 1 of a continuously-coating line, the temp. wherein cross-linking reaction of resin for coating is started is regulated to the temp. below 10 deg.C or more. The b.p. of a solvent is regulated to the temp. below 10 deg.C to 30 deg.C. The resin is held in a time not shorter than 10sec and not longer than 25sec. Thereby the cross-linking reaction of resin is inhibited and evaporation of the solvent is made slow. Generation of bubbling based on violent evaporation of the solvent is prevented. Further the holding time is increased or lowered by thickness of the coated film. There is constraint in coating thickness of one time due to a roll coater 4. As a result, bubbling is not caused in 10sec or 25sec and also sufficient holding time is obtained.

Title: Power unit and power saving method
Inventor: MIRUMACHI TAKASHI
IPC: G05F1/70
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption when the output power of a power unit equipped with an active filter decreases by providing an intermittent control means which intermittently drives the active filter when the output power of the power unit decreases below a specified value. SOLUTION: When the output voltage of the active filter drops in a stationary state and the level of the output Caout of a current error amplifier decreases, the output of a comparator CP1 changes from Low to Hi and the output of a comparator CP2 remains Hi. Hence the output of driving pulses decreases. The comparator CP2 changes its output to Low only when an output Vaout increases above a set value. At this point, the comparator CP1 already receives the change of an increase in output Vaout and its output changes to Low. Hence an active control circuit executes a software start. Operation for returning to a stop state is repeated and intermittent operation is entered.

Title: Preparation of single crystal layer
Inventor: ISHIDA TOSHIMASA
IPC: C30B29/08
Filed: 1983-11-14
Abstract: PURPOSE:To prepare a semiconductor thin layer of Ge single crystal having uniformity and high quality, by setting Si layers and Ge layers in specific shape and arrangement relationship on an electrically insulating prime-coating layer (substrate), carrying out two-dimentional zone melting. CONSTITUTION:The thin layers 12 of Si semiconductor having the width W1 are extended in the vertical direction of paper on the figure are set on the electrically insulating prime-coating layer (substrate) 11 in a beltlike state, and on the layers the thin layers 13 of Ge semiconductor having the width W2 (W2 is about ten times as long as W1) are set in a bletlike state in such a way that the central parts of the thin layers of Ge semiconductor are positioned at the thin layers 12 of Si semiconductor (if necessary, the thin layers of Ge semiconductor are wholly covered with the electrically insulating protecting film 14).

Title: Variable amplifier circuit
Inventor: FUKUDA EISUKE
IPC: H03G3/10
Filed: 1991-08-26
Abstract: PURPOSE:To miniaturize this variable amplifier circuit as an LSI by adding/ subtracting an output from a volume for inputting a signal to which a DC offset voltage is superposed as an input signal and an output from an electronic volume for inputting only the DC offset signal as an input signal to offset a change in the DC offset voltage. CONSTITUTION:An electronic volume(EV) 1 inputs an input signal (v+V) obtained by superposing a DC offset voltage V to a low frequency AC signal v and outputs an output voltage G(v+V) with variable gain G. An electronic volume(EV) 2 inputs only the voltage V as an input signal and outputs an output voltage GV with the same gain G. An adder/subtractor 3 adds/subtracts the outputs G(v+V) of the EV 1 and the output GV of the EV 2 and obtains an output signal V0=-Gv+V to offset a change in the voltage V. Since the V in the V0 becomes independent of the gain G of the EV 1 and EV 2, a fixed voltage is held. Thereby the generation of a change in the V can be prevented and a circuit appropriate for miniaturization and LSI formation can be obtained.
