IPC: B23B41/00
Filed: 1995-11-22
Abstract: PURPOSE: To improve position accuracy and quality of a drilled hole by repeating the operation to move the drill from the first intermediate position to a withdrwal position at a rapid speed after moving the drill a machining start position to the first intermediate position at a notching feed speed and the operation to move the drill from the withdrawal position to the next intermediate position at a cutting feed speed. CONSTITUTION: The drill 4 is moved from a machining start position A to the first intermediate position M1 through a withdrawal position C at a notching feed speed, forming a hole, which penetrates an upper plate 2 and bores into the printed circuit board 1 at the top of the upper plate 2. Then, the drill 4 is moved to the withdrawal position C from the intermediate position M1 at a rapid speed.

Title: Foam discharging opening
Inventor: IMAZONO MASAHIKO
IPC: E03C1/084
Filed: 1989-11-21
Abstract: PURPOSE:To eliminate pressure loss and clogging of foreign matter by a method wherein a foaming chamber and an air passage in communication with a whirling stream chamber are provided and the foaming chamber is provided with a reverse flow prevention mechanism. CONSTITUTION:When water is supplied from a spout 50, the water runs into a downstream side chamber 8 from its outer periphery along the inner wall thereof and joins the water from a hole 6a and a stream thus formed starts a rotating movement therein while creating a swirl. In the downstream side chamber 8, the fluid energy of the water itself increases and a centrifugal action takes place due to a whirling stream to form the dropping water into a cone- shaped water screen F for discharging. Since a discharge opening 3a is located in the center of a foaming chamber 5 and since the water runs out at a high speed accompanied by centrifugal force, an inner spatial pressure inside the cone-shaped water screen F is decreased, whereby air is sucked in from an air stream 22a to produce foam. The foamed water runs into a water diffusing hole 21 and its stream is straightened by a current plate 23 for discharging.

Title: Tape cassette
Inventor: SATO SHINYA
IPC: G11B23/087
Filed: 1989-11-24
Abstract: PURPOSE:To reduce cost, to eliminate the necessity of surface finishing and to simplify the inspection of a product as well by forming a tape guide by using ultra-high molecular weight polyethylene resin which molecular weight is 500,000-1,000,000. CONSTITUTION:By combining the ultra-high molecular weight polyethylene resin and carbon black, a frictional characteristic and quality equal to a metallic tape guide is maintained. Namely, as the molecular weight of the ultra-high molecular weight polyethylene resin, the range of 500,000 to 1,000,000 is prefer able and when it is smaller than 500,000, there is tendency that damage to a tape is large and a frictional coefficient is increased. When it is larger than 1,000,000, for the tape guide, molding is made difficult and the tape guide is too soft in strength and easily deformed. For the stable characteristic, the rate of the carbon black to be mixed is 1-15wt.% and surface electric resistance is set to be 10<2>-10<12>OMEGA.

Filed: 1994-12-09
Abstract: PURPOSE: To make it possible to execute data transmission with a task in another CPU and data transmission with a task in its own CPU by the same procedure in a data processor with multi-CPU constitution. CONSTITUTION: In the case of transmitting data from a task 31 to another task, the task 31 acquires a message box 21a, stores data in the box 21a and requests an operating system (OS) 21 to transmit data to the other task.
