Title: Blade plate-attaching structure in mower
Inventor: ITO KAZUO
IPC: A01D34/73
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To provide a safe blade plate-attaching structure wherein a rotary blade plate and a blade plate-supporting plate for supporting the blade plate can simply be attached or detached and wherein the once attached blade plate or blade plate- supporting plate is easily not dropped out, in a mower for cutting weeds, bushes, lawn grasses, etc. SOLUTION: Headed attaching bosses 7 are disposed on a rotation track apart from a rotation center in a constant distance at a prescribed distance on a rotary portion to which a blade plate and a blade plate-supporting plate are attached. Oval holes 8, each comprising a large diameter portion permitting the passage of the head portion of the attaching boss 7 and a narrow portion permitting the passage of the shaft portion of the attaching boss 7, are disposed at positions corresponding to the positions of the attaching bosses 7. A partially cut, elastic, circular, slip-off stopping metal plate 9 is attached to the attaching bosses 7 to which the blade plates, etc., have been attached. Oval holes 10 corresponding to the positions of the attaching bosses 7 are formed in the slip-off stopping metal plate 9. One oval hole near to the cut portion is formed in a deformed oval hole shape wherein the large diameter portion is extended in the range of the narrow portion. While the deformed hole portion is floated, the slip-off stopping metal plate 9 is attached or detached, thereby preventing the careless drop of the slip-off stopping metal plate 9.

Title: Welding groove of welded joint part of clad steel
Inventor: KOBAYASHI HIROSHI
IPC: B23K9/23
Filed: 1979-03-02
Abstract: PURPOSE:To prevent the production of the brittle parts at the penetration parts of both ends where cracks are produced by undercuts and bends with less number of welding by forming the both ends of the chipped-off part of the clad steel into two- stage shape in the joint undergoing one layer hand arc welding. CONSTITUTION:shelves 12 are provided to the both ends of the chipped part of the clad member 1 for the pressure vessel of chemical equipment, etc. so that they are made into two stages. As a result of this, the thickness requiring build-up is less at the both end parts than the central part and therefore if hand arc welding is done, no undercuts will be produced. Further, the penetration of the both end parts goes down to the base metal 2 owing to the shelves 12 and therefore the brittle parts 9 becomes only the portions approximately equal to the plate surface. It is equally well to provide one-layer weld zones 13 to the both end parts in place of the shelves 12.

Title: Method for exposure
Inventor: SUZUKI AKIYOSHI
IPC: H01L21/027
Filed: 1984-02-14
Abstract: PURPOSE:To reduce the non-uniformity of an exposure energy given to each chip and thereby to enable the efficient execution of exposure, by applying rough exposure first and modification exposure secondly to each chip on a wafer in a semiconductor exposure apparatus. CONSTITUTION:A plurality of chip regions are put in one group, and rough exposure and modification exposure are applied thereto (one step). This step is repeated thereafter. First the rough exposure (black circles) and modification exposure (white circles) are applied to a line C1 of the chip regions and thereby the exposure of the line C1 is completed. Thereafter the rough exposure and the modification exposure are applied sequentially to each of lines C2, C3, C4 and C5 of the chip regions. A light source is controlled so that a first pulse energy of the rough exposure be about 80-90% of a proper exposure energy and that the remaining necessary exposure energy be given by a second pulse energy of the modification exposure. By this constitution, a strict control of exposure is made possible even when the second pulse fluctuates a little, since the rate of the fluctuation to the entire proper amount of exposure is small.

Title: Logic circuit
Inventor: OTAGURO YUKIO
IPC: H03K17/04
Filed: 1991-02-19
Abstract: PURPOSE:To prevent a through current from being generated in the case of an intermediate potential and to respond to a change at high speed even when the transition of an input signal is smooth by using a signal delaying an output. CONSTITUTION:Pch FET P11 and P12 and nch FET N11 and N12 have driving ability at the same degree, and the absolute value of a threshold voltage is lower than a middle point at the height of a power supply potential. These FET are connected between power sources as prescribed, and an input signal and a feedback signal are applied to a prescribed gate terminal. The signal delay time of a delay circuit 1 is set larger than the rise/fall time of the input signal. Therefore, the level of the output signal is held until the normal state of the FET is established by the transition of the input signal level, all the FET are simultaneously conducted, and the through current is prevented from being generated. The transistor size of an inverter 2 is made enough small in comparison with the P11-N12, and current driving ability is set low. When a logic circuit is turned to a normal state, the inverter 2 prevents the output terminal from turning to a floating state and establishes an output signal potential.
