IPC: B23D63/12
Filed: 1986-01-07
Abstract: PURPOSE:To enhance the sharpness of a saw blade, by subjecting the sawblade to tilting motion so that the front end face of the set of the saw blade is aligned with the radial direction of a grindstone, and therefore, the polished and corrected edge of the saw blade is made to be orthogonal to the surface of the set. CONSTITUTION:A sawblade 1 is clamped on a semicircular clamp bed 5 which is meshed with a pinion gear 4 at its outer periphery, so that the reference point (root line) of the set of the sawblade is located at the center of the clamp bed 5. With this arrangement, the clamp bed is tilted right and left, and therefore the saw blade 1 is tilted about the root line as a center. At this time, the pinion gear 4 is subjected to a predetermined swing motion by means of a suitable mechanism or the like including a link 6 so that the front end face of the set of the sawblade 1 is aligned with the radial direction of a grindstone 2, that is, the font end face of the set of the sawblade is made to be vertical. further, it is sufficient to conduct the motion of the grindstone 2 at this time such that swing motion is applied synchronized with the feed of the sawblade.

Title: Peak value detection circuit
Inventor: HOSONO YASUHIRO
IPC: G01R19/32
Filed: 1991-01-11
Abstract: PURPOSE:To achieve stabilization by suppressing fluctuation of an output signal and prevent a production cost from being increased simply by adding a simple circuit. CONSTITUTION:By transmitting output signals V1 and V2 of a pre-stage differential circuit 10 whose peak value is to be detected to a full-wave rectification circuit 1 through capacitors C1 and C2, fluctuation of an output signal V0 due to fluctuation of a DC voltage of the signals V1 and V2 is eliminated. Also, since resistance elements R1-R4 are formed to have an equal layer resistance, a high level of the signal V0 is determined only by a setting ratio of the elements R1-R4 regardless of fluctuation and temperature change of process conditions at the time of manufacture, thus enabling level fluctuation to be suppressed. Also, the low level of the signal V0 is determined by ON resistance of transistors Q1 and Q2 and fluctuation can be ignored by setting the resistors R1-R4 to approximately several KOMEGA since this ON resistance is approximately several 10OMEGA. Therefore, a stable signal V0 can be obtained without being affected by influence of the circuit 10 or temperature change, production process, etc.

Filed: 1993-01-08
Abstract: PURPOSE:To completely insulate a silicon carbide seed crystal layer from a silicon substrate by thermally oxidizing a silicon substrate containing a selectively grown silicon carbide seed crystal layer, and growing a silicon carbide film in a horizontal direction until an opening is blocked, to form a field oxidization layer. CONSTITUTION:An opening 35 for seed crystal growth is formed in a silicon oxide film 32 on a silicon substrate 31, and the surface of the substrate 31 is selectively exposed, then a silicon carbide single crystal is epitaxial-grown from the opening 35 to form a silicon carbide seed crystal layer 36. The film 32 is grown in a horizontal direction until the opening is blocked, to form a field oxidization layer 37. Thus, only by thermally oxidizing the substrate 31 containing a selectively grown silicon carbide seed crystal layer 36, the layer 37 can insulate the layer 36 from the substrate 31 thoroughly. Therefore an SOI construction can be obtained by a simplified production method.

Abstract: PURPOSE:To lower a noise level in a simplified structure, by forming a main combustion chamber and a swirl chamber in the head of piston and providing a cylinder head with a fuel nozzle having two nozzle holes formed therethrough, while at the same time reducing the diameter of nozzle bore for the swirl chamber and increasing the diameter of nozzle bore for the main combustion chamber. CONSTITUTION:While a main combustion chamber 2 and a swirl chamber 3 are formed at the head 11 of piston 1, a hot plug 5 having an opening 31 is secured to the upper surface of swirl chamber 3. A cylinder head is in turn provided with a fuel nozzle 7 having two nozzle holes 71, 72 formed therethrough. While the swirl chamber 3 has its nozzle bore 71 reduced in diameter, the main combustion chamber 2 selects a larger diameter for its nozzle bore 72. This arrangement permits the nozzle hole 71 to inject a fuel from it while a fresh air is swirling inside the swirl chamber 3, so that a fuel- air mixture is ignited and burnt in an optimum manner. Then, a flame is injected from inside the swirl chamber 3 to the main combustion chamber 2, igniting and burning a fuel injected from the nozzle bore 72 to the wall surface 22 of main combustion chamber 2. In this way, the cylinder can lower its maximum internal pressure, and thereby achieving a purpose as desired.
