Patent JP-H01120817-A (JP)
Title: Manufacture of semiconductor device
Inventor: FUKANO SATORU
IPC: H01L21/265
Filed: 1987-11-04
Abstract: PURPOSE:To facilitate suppression of the diffusion of a previously formed 1st impurity region by a method wherein impurity ions are implanted into a 2nd region, the 1st impurity region is covered with a microwave reflecting film, a microwave is applied to the 2nd region and the impurity ions are activated to form a 2nd impurity region. CONSTITUTION:A resist film mask 12 is provided on a p-type silicon substrate 11 and phosphorus ions are implanted into the exposed surface of the substrate 11 which is not covered with the mask. Then a microwave is applied and the phosphorus ions are activated to define an n-type impurity region (1st impurity region) 13. Then a silicon oxide film 14 is applied and further an aluminum film 15 is applied to the oxide film 14 and the films 14 and 15 are patterned by a lithography technology so as to cover the n-type impurity region 13 selectively. After that, arsenic ions are implanted into an exposed surface. Then a microwave is applied again to the surface and the arsenic ions are activated to define an n<->type impurity region 16. At that time, the aluminum film 15 serves as a microwave reflecting film to reflect the microwave so that the n-type impurity region 13 beneath the aluminum film 15 is not heated and the diffusion of that region 13 can be suppressed.

The groove section at the back side of the convex part 1 accommodates a rotary inner edge in such a way that the inner edge can rotate along the groove. A thin sheet is shear-pressed to provide the slots, and then drawing-pressed to form three-dimensional outer edges. Thus, the outer edge is produced by an integrated press working line consisting of two or more steps.

Title: Multistage flash evaporator
Inventor: YANAGI HIROTOSHI
IPC: B01D3/06
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To significantly increase the evaporation efficiency through moving hot brine from a lower layer to a surface layer by forming a bypass flow path which passes through the lower part of a weir and generates an ascending flow to mix the lower layer brine of a weir upstream side with the upper layer brine of the downstream side. SOLUTION: When hot brine flows into a left hot evaporation stage 2a of an evaporation chamber 2 from an orifice 10 at the lower end part of the left wall 1a of a housing 1, most of the hot brine flows over the upper end of a perpendicular plate walllike weir 20 to undergo such a process as a pressure drop or a flash evaporation due to the decrease of a liquid depth in the following evaporation stage. Further a part of the hot brine flows into a downstream side brine layer through a bybass flow path 21 at the lower part of the weir 20. The outlet of the flow path 21 is angled upward to push up the lower layer brine to an upper layer where the brine flash- evaporates due to the decrease of the liquid depth.  Next the brine enters a right low temp. evaporation stage 2b through an orifice 10 at the lower end part of the center partition 4 in the evaporation chamber 2, and flash-evaporates in the same behavior as in the left hot evaporation stage 2a. Thus the unevaporated brine at the bottom of the evaporation chamber 2 is pushed up to the upper layer to increase the flash evaporation volume of the brine and increase the evaporation efficiency.

A data buffer 14 temporarily stores data so as to send and receive the data to and from the outside. A recording and reading part 15 sends and receives the data to and from the data buffer 14 according to commands and records or reads data to or out of a magnetic disk drive. An error processing method selection part 16 selects an error processing method according to the estimated margin time if an error occurs and an error processing part 17 processes the error.

Title: Device having at least two fly mass bodies capable of relative turning movement around rotary shaft
Inventor: PAURU MAUHAA
IPC: F16F15/131
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To improve the noise and vibration damping capacity in a torque limiting device by allowing transmittable torque to be different in the direction of propelling torque and in the direction in which torque is propelled. SOLUTION: A shock absorber 13 and a friction-slide clutch 14 are provided between fly mass bodies 3, 4 to make a relative turning movement possible. Thus, with an axially preloaded belleville spring 34, its tongued piece 40 radially inwardly projected from a circular ring-like outside region 39 applies a load to a disc 30 toward a friction surface 29 by the inside edhe region 36 of the tongued piece. In state where an engine is stopped, torque of the clutch 14 transmitted by force acting on the outside region 39 of the belleville spring, is smaller than the rated torque of the engine. A section 41 axially shifted relative to the outside region 39, and a tongued region 42 are allowed to apply a moment to the outside region 39 by means of centrifugal force generated during the running of the engine, and thus to transmit axial force to the disc 30.  The axial force is increased with increasing the number of revolutions. Thus, at the lower idling speed, torque can be slightly transmitted, and the load to driving system, and noise can be reduced.
