Title: Soldering device for flat package ic
Inventor: GOTO TADASHI
IPC: H05K3/34
Filed: 1987-08-19
Abstract: PURPOSE:To ensure a soldering at a lower heater chip temperature and improve reliability, by soldering while forming a step at the bottom end of a heater chip so that a solder can directly be heated and pressurized. CONSTITUTION:By forming a step at the bottom end of a heater chip 28, both a lead 12a and a solder 37 placed on a pattern are directly heated and pressurized by a heater chip 28.

Title: Lathing device
Inventor: SATO GENICHI
IPC: B23B27/10
Filed: 1990-08-01
Abstract: PURPOSE:To achieve good cutting by providing a high pressure liquid discharging nozzle to discharge high pressure liquid to a workpiece toward a cutting point from the side opposite to the side where the cutting blade of a cutting tool enters, and thereby keeping the cutting point in a constantly-cooled condition while cooling the same by means of high pressure liquid. CONSTITUTION:A high pressure liquid discharging nozzle 15 cools down a cutting point by discharging high pressure liquid from the side where chips are produced by means of the cutting blade tip 11a of a cutting tool. The high pressure liquid serves to drive out the produced chips and at the same time cool down instantaneously, to keep in cooled condition, the part of a workpiece 3 where the tip of the cutting blade 11a enters, resulting in little heat effect of both the workpiece 3 and the cutting blade tip 11a. Thus, the workpiece will neither be hardened as in the case of quenching even if the workpiece 3 is made of carbon steel such as S45C, nor built-up edge will be formed by melted surface of the workpiece 3 caused by cutting heat, nor dimensional warp and distortion will be caused by thermal expansion.

Filed: 1982-11-25
Abstract: PURPOSE:To perform safe idling by setting the integration term of control operation formula to predetermined level if stepping of accelerator pedal is zero at the time point when the speed of internal-combustion engine transfer from high to low rotation region. CONSTITUTION:If the stepping of accelerator pedal detected by a detector 7 is zero upon transfer of engine rotation (N) detected by a rotary sensor 4 and shaper circuit 8 from high to low rotary region, a speed controller 1 comprising a microcomputer will set the integration term of specific proportion/integration control operating formula to predetermined value. Consequently engine rotation due to drive circuit 12, actuator 13 and injection pump 3 will drop slowly and when determining the integration term while considering engine characteristic, desired idling speed can be achieved without causing undershoot phenomena.

IPC: F04D29/28
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To restrain air flow from separating from a negative pressure surface by forming a concave or convex at a downstream side surface in a rotating direction in a vane. SOLUTION: Vanes 13 are formed so as to curve in a radial direction of a fan body, and concave and convex curved surfaces respectively serve as a suction surface 21 and a positive pressure surface 23. The suction surface 21 is a surface at an downstream side in a rotating direction of a fan body as indicated by arrow A, and the positive pressure surface 23 is a surface at an upstream side in the rotating direction. A projection 25 of semi-circular surface in section is provided on the suction surface 21 of the vane 13. Though wind flow is generated between the adjacent vanes 13, 13 due to rotation of the fan body, a wind T flows along the positive pressure surface 23 in the positive pressure surface 23 receiving a wind pressure. On the other hand, in the suction surface 21 of each of the vanes 13, the wind tends to separate from the suction surface 21 as indicated by arrow P.  However, the projection 25 generates a plurality of vortexes (n), and disturbance occurs. Accordingly, the wind is sucked to the suction surface 21 side as shown in arrow S when the disturbance occurs, the wind S is restrained from separating.

Filed: 1989-08-09
Abstract: PURPOSE:To settle such problems as snapping and slackening that often occurred with a conventional shoelace by forming a shoelace by knitting a Kevlar fiber in the conventional process or by using Kevlar fiber only as the core material of shoe string. CONSTITUTION:Para-oriented wholly aromatic polyamide fiber, or Kevlar fiber is said to be a fiber with a tensile strength 5 times higher than iron, but it is inferior in weather resistance. Therefore strong but unductible Kevlar fiber is used as the material of shoelace. By processing the surface with resin containing pigments to improve weather resistance of the shoelace very hard to snap and slacken and also very difficult to discolor can be obtained.

Abstract: PURPOSE:To search quickly a desired track by pushing continuously a forward or reverse switch to search the tracks on a disk and displaying the searched track numbers as soon as a tracking action is over. CONSTITUTION:When a forward or reverse switch PWD5 or RV6 is closed, a controller 60 reads a forward or reverse operation according to the key scan which is carried out by obtaining the timing from a timing pulse PG obtained immediately after a switch-on mode. A tracking command is sent to a drive circuit 50 of a magnetic head 26 from the controller 60 for the searching purpose. A tracking end signal is produced when a tracking action is over. Then a track number display command is produced synchronously with a VSYNC delivered during generation of signals. Thus the searched track numbers are displayed.

Title: Mechanical seal
Inventor: KASHIWAMURA KAZUO
IPC: F16J15/34
Filed: 1987-08-20
Abstract: PURPOSE:To enable a long-time use by forming a minute gap which is opened on the inner periphery side of a sealed end face on either of the sealed end faces of a seat ring and a driven ring, providing spiral grooves on its surface, and forming lubricating grooves on the part of the sealed end face on which the minute gap is not formed. CONSTITUTION:A minute gap 23 which is opened on the inner periphery side of the sealed end face of a driven ring 2 side is formed on the end face, and spiral grooves 25 provided on its surface are inclined rearward in the relatively moving direction of the sealed end face. Due to these spiral grooves 25 provided on the sealed end face on which the minute gap 23 is formed, a pressure in the radial direction which can oppose to a leaking flow can be effectively generated utilizing the relative rotation of the sealed end face, with respect to a sealed fluid 14 existing in the minute gap 23 of the sealed end face 18. And, a nearly completely sealing fluid film can be formed on the sealed end face 18 due to lubricating grooves 26 provided on the part of the sealed end face 18 on which the minute gap 23 is not formed. Thereby, the captioned seal can stand a long-time use under a severe condition while suppressing the leakage of the sealed fluid 14 to be vary small.
