Title: Drilling screw
Inventor: KANEKO YOSHIHIRO
IPC: F16B5/02
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a drilling screw which can screw a gypsum board on a C-shaped structural material made of thin steel plate by means of an impact type pneumatic-drive thread fastening machine. SOLUTION: In a drilling screw 11, a parallel threaded part 13 is connected through a taper threaded part 14 to a small diameter parallel threaded part 15. The ridge of the small diameter parallel threaded part 15 is formed extremely low as a height of about 0.1mm, and a taper bit part 16 is formed at the top of the small diameter parallel threaded part 15. The drilling screw 11 is driven into a gypsum board and a C-shaped steel plate structure by means of an impact type pneumatic-drive thread fastening machine, so that the small diameter parallel threaded part 15 pierces the steel plate. The diameter of the small diameter parallel threaded part 15 is so extremely small that it hardly deforms the steel plate.  The minute ridge of the small diameter parallel threaded part 15 is screwed into the steel plate with producing a driving force in a screwing direction during its rotation for connecting the gypsum to the C-shaped steel plate structure.

Title: Suction system of engine
Inventor: TANAKA NOBUHIKO
IPC: F02D33/00
Filed: 1990-08-13
Abstract: PURPOSE:To restrict an increase of the quantity of intake air by ensuring a larger quantity of intake air under a full load by means of the action of a forced valve opening/closing mechanism, thereby increasing the output of an engine, and closing a shutter valve for a partial load together and shutting off a by-path passage by means of a rotary valve at the last period of a suction stroke. CONSTITUTION:When a low engine speed is load accompanied under a partial load, a shutter valve 58 is fully closed and intake air is carried out through a by-path passage 60. In addition, owing to a VVT mechanism 43, opening timing of an intake valve 18 is delayed, and an overlapping region between a valve opening region of the intake valve 18 and that of an exhaust valve 20 becomes small. In addition, owing to the action of a forced valve opening/ closing mechanism 29, an opening angle of the intake valve 18 increases, liable to take in an excessive quantity of air. Since at the last period of a suction stroke the by-path valve 60 is shut off by a rotary valve 62, the intake air is cut before the intake valve 18 is closed. On the other hand, since under a full load, the shutter valve 58 is opened and moreover the opening angle of the intake valve 18 is increased, a larger quantity of intake air can be ensured.

The last day (28th) of February and the last day (31th) of January are the same day of the week. In an intercalary year, the last day (29th) of February and 1st February are the same day of week, so the last day of January is the day of the week which is one day precedent. The figure obtained by using said results is the 'double- number type'. The figure of 1st days of respective months based upon the last day of February is the '1st-day type'. Consequently, days of the weeks of all years are known by knowing the last data of February.

Abstract: PURPOSE:To improve the crystallinity and reliability of a semiconductor laser which forms laser structure on a grooved substrate by filling a groove with two lasers and forming an active laser after the third layer and by reducing the band gap of the first layer less than that of the active layer. CONSTITUTION:A p-GaAs substrate 1 whereon an n-GaAs layer 2 is grown for current blocking is used as a substrate. This substrate is V-grooved. A p-Al2Ga1-zAs layer 3 of the first layer is grown so that the groove is buried to some extent by reducing time required for growth.
