Title: Vitrified super abrasive grain grinding wheel
Inventor: WAKUTA MANABU
IPC: B24D3/14
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To easily judge replacing time of a grinding wheel with the naked eye by forming a shape of a boundary line of a super abrasive grain layer and a backing layer in a cross section passing through the axis of a grinding wheel segment in a shape different from a cross-sectional shape of the grinding wheel work surface. SOLUTION: When grinding work is continued, the thickness of a super abrasive grain layer 4 reduces soon by abrasion by work and consumption by truing work, so that the grinding wheel work surface 2a gradually retreats. When the grinding work is continued further, since a boundary line Cb of the super abrasive grain layer 4 and a backing layer 5 is formed in a shape different from a cross-sectional shape Ca of the grinding wheel work surface 2a, the backing layer 5 finally appears in a part of the grinding wheel work surface 2a. Therefore, the fact that grinding wheel replacing time approaches since the thickness of the usable super abrasive grain layer 4 reduces, can be easily judged with the naked eye of an operator even at time of grinding wheel rotating by monitoring a color change in the grinding wheel work surface 2a.

Abstract: PROBLEM TO BE SOLVED: To enable setting of a reference waveform for the control of a laser output waveform to various types of waveform patterns through a simple user's operation. SOLUTION: On a 'schedule' screen display of a display unit, a user inputs a desired set value or an instruction for the operation of an apparatus through keying operation. In particular, in order to set and input a reference waveform for waveform control, the user sets and inputs the desired numeral data for a laser output reference value 'PEAK' and for waveform elements '↑SLOPE', 'FLASH1', 'FLASH2', 'FLASH3' and '↓SLOPE' as items. On the basis of the values set and input in the items, the apparatus finds the graphs of a reference waveform for waveform control and of a reference waveform for displaying. The reference waveform for waveform control is used for the reference value of the waveform control in a laser output waveform control part.  The graph of the reference waveform for display is indicated on a display screen in a predetermined area, in response to a predetermined key.

Title: Light device
Inventor: YOSHIMATSU MORIO
IPC: G03B15/035
Filed: 1995-03-17
Abstract: PURPOSE: To surely electrically detect that the light for illumination different in wattage is erroneously fitted and to prevent abnormal heat generation from occurring when the light for illumination different in wattage is erroneously fitted. CONSTITUTION: A control transistor Qa is serially connected to the light 71 for illumination driven by a DC voltage. A current detection means 87 detecting a light current flowing to the light 71 is connected. The detection means 87 is constituted of a resistor for detecting a current 88 connected to the inside of the current path of the light 71, a comparator 90 detecting the voltage of both ends of the resistor 88 and a switching transistor Qc. Then, the transistor Qc is connected to the transistor Qa. When the excess current is detected by the detection means 87, a switching element is actuated and the transistor Qa is turned off. Thus, even when the light having equal to or over the prescribed wattage is inadvertently fitted, it is immediately detected and the transistor Qa is controlled to be turned off, and the abnormal heat generation is prevented.

Title: Fuel property detecting device and fuel injection amount control device of internal combustion engine
Inventor: KITAMURA TORU
IPC: F02D45/00
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a fuel property detecting device capable of detecting fuel property without using a new sensor. SOLUTION: In a transient state in which an absolute value of changed amount DPBA of absolute pressure PBA within an intake pipe becomes larger than prescribed changed amount DPBA0, a fuel property parameter KGAS is calculated (S16). The fuel property parameter KGAS is calculated based on a detection value of an air fuel ratio sensor 22 provided on an engine exhaust system. For instance, just after fuel supply amount to the engine is increased, volatility of fuel is decided to be high as the detection value of the air fuel ratio sensor 22 becomes closer to a rich side. Based on this decision, a value of the fuel property parameter KGAS is determined.
