A technique is provided which is effective in preventing chips generated during cutting operation on a workpiece from being accumulated in a region ahead in a cutting direction. A representative cutting machine includes a motor, a blade, a body housing having a first region that houses the motor and a second region that covers the blade and projects forward of a front surface of the first region, a base, an angular plate, an outlet formed in the body housing, an opening and a blocking part. The blocking part prevents the air discharged from the outlet from flowing out laterally with respect to the moving direction of the base through a clearance between a front end of the second region and the one end of the angular plate and thereby helps the air discharged from the outlet flow into the opening.

A brake device includes a pad 100a having a friction surface 101 and a disk 200a having a friction surface 201 sliding on the friction surface 101. The friction surface 101 includes hard particles 102 that are elastically supported in a y direction perpendicular to the friction surface 201. The friction surface 201 includes a plurality of convex portions 202 that is disposed in a direction where the friction surface 201 slides on the friction surface 101. When the friction surface 201 slides on the friction surface 101, the hard particles 102 continuously come into contact with the convex portions 202, respectively, while being displaced in the y direction perpendicular to the friction surface 201. Accordingly, the brake device can improve abrasion resistance as compared to a brake device that mainly performs abrasive friction. When the hard particle 102 comes into contact with the next convex portion 202 after coming into contact with one convex portion 202, the hard particle 102 comes into contact with the convex portion 202 at a position lower than the apex of the convex portion 202. Accordingly, the hard particles 102 continuously come into contact with the convex portions 202 so as to follow the convex portions 202, respectively. Therefore, it may be possible to obtain a larger frictional force.

An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet; a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit; and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet, wherein, as the temperature of the re-transport roller sensed by the temperature sensing unit is lower, the control unit retards a timing to cause the sheet feed unit to start the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.

A speech recognition rule learning device is connected to a speech recognition device that uses conversion rules for conversion between a first-type character string expressing a sound and a second-type character string for forming a recognition result. The character string recording unit records a first-type character string and a corresponding second-type character string. The extraction unit extracts second-type learned character string candidates. The rule learning unit extracts, from the second-type learned character string candidates, a second-type learned character string that matches at least part of the second-type character string in the character string recording unit; extracts a first-type learned character string from the first-type character string in the character string recording unit; and adds the correspondence relationship between the first-type learned character string and the second-type learned character string to the conversion rules.

A dust collecting device for collecting cutting chips into a dust collecting container is provided. A back-flow preventing wall(s) is fixedly disposed on a flow path member defining a flow path between a machining apparatus and the dust collecting container. The back-flow preventing wall(s) is configured to decrease a cross sectional area of a flow path part defined by the flow path member in a downstream direction with respect to the flow of the air containing the cutting chips toward the dust collecting container.

Disclosed are a method and an apparatus designed to make a window envelope rapidly using a water-soluble clarifying agent without causing an inconvenience in its window area. Upstream of an envelope making stage wherein a continuous paper while traveling along a continuous path of travel is successively folded, pasted and cut to form an envelope, a water-soluble clarifying agent is applied to an area on the continuous paper that is designed to become the transparent window in the envelope and the continuous paper carrying the clarifying agent is wound on a plurality of drying cylinders so that its surface carrying the clarifying agent faces outwards to dry the clarifying agent while holding the surface of paper carrying the clarifying agent out of contact with the drying cylinders.

A stroke characteristic variable engine comprising a primary link connected to a piston which is slidably fitted in a cylinder, a secondary link connecting the primary link with a crankshaft and a tertiary link connected to the primary link or the secondary link at one end and to an engine main body via a control shaft at the other end thereof. An oil level position of engine oil stored in an oil pan is set such that at least part of the control shaft is submerged in the engine oil, whereby since oil stored within the oil pan can be used as it is, the lubrication around the control shaft can be ensured in a simplified configuration.

Provided is a variable stroke property engine that can prevent an increase in the resistance to the engine owing to the contact between the variable stroke piston mechanism and lubricating oil. In a variable stroke property engine equipped with a variable piston stroke mechanism consisting of a plurality of links 4, 5 and 12, a baffle plate 40 is provided between the links and the oil surface of the lubricating oil received in an oil pan so that the links may be separated from the oil surface by the baffle plate and the lubricating oil is prevented from contacting the links. Thereby, an increase to the resistance to the movement of the links can be avoided.

A simulation coverage calculating apparatus is provided for calculating a simulation coverage for a complete verification. The apparatus includes a first input unit, a second input unit, an effective test pattern calculating unit, a coverage ratio calculating unit, and an output unit. The first input unit reads a property that represents effective test patterns to a logic circuit to be verified. The effective test pattern calculating unit calculates the effective test patterns based on the property. The second input unit reads the test patterns entered and executed by a verifier. The coverage ratio calculating unit calculates a coverage ratio from a ratio of the number of the test patterns matched to the effective test patterns to the number of all of the effective test patterns. The output unit outputs the calculated coverage ratio.
