Inventor: SATO TADAYUKI
IPC: B21C37/15
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain the manufacture of a tapered square pipe and its device which have high productivity and which provide a uniform finished dimension and shape. SOLUTION: Used in the device are a fixed lower female die 12 having a V-shaped recess, a vertically movable upper female die 14 having an inverted V-shaped recess, a vertically movable core 21 having a truncated pyramid shape, and a left and right side dies 22 which are each retractable outward left and right. A spread cut plate base material 1 is placed on the side die. With a pressurizing part lowered, the core descends, so that the first, second and third bend positions a, b, c of the base material are bent with the core, lower female die and side die. Then, the pressurizing force is prevented from affecting the core.  With the pressurizing part further lowered, the upper female die descends, so that the first bend position a and the third bend position c of the base material are further bent with the recess of the upper female die, and that the fourth bend position d is also bent with the V-corner part of the recess of the upper female die to form the shape of a tapered square pipe. By raising the upper female die, the formed product of the tapered square pipe is taken out from the core to the small diameter side.

Title: Lamination type heat exchanger
Inventor: YAMAMOTO YOSHIAKI
IPC: F28F3/04
Filed: 1984-06-01
Abstract: PURPOSE:To obtain the simple lamination type heat exchanger having a low pressure loss and a high heat transfer coefficient by a method wherein the developments of speed and temperature boundary layers are restrained by a thin plate fixed to the inside of a groove to coincide the direction of disturbance of the flow of fluid with the direction of movement of heat. CONSTITUTION:The thin plate 10, supported by the side surfaces of a flow path 11, divides the flow path 11 into two divisions while the thin plates 10 are provided with spaces in the direction of flow of fluid. The direction of flow of fluid is changed to the directions of upper and lower walls at the upstream side of the thin plate 10 and whereby the developments of speed and temperature boundary layers are restrained. The heat transfer coefficient is increased very much at a part where the fluid collides against the wall surface and the average heat transfer coefficient in the whole of the flow path is increased. On the other hand, the pressure loss is somewhat increased, however, the increase of heat transfer coefficient may be larger as compared with the increase of the pressure loss.

Title: Semiconductor integrated circuit device, and its manufacture
Inventor: HONMA SOICHI
IPC: H01L21/60
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To suppress migration or corrosion, by a barrier metal layer covering a rewiring layer completely, and also having a projecting section projected onto a passivation film. SOLUTION: A projecting section 9 on a passivation film 4 repels the force to shift when a rewiring layer 6 is about to shift by mechanical or electrical force, and it goes up by this action, and can suppress migration of the rewiring layer. The projecting section 9 makes an electrolyte and the rewiring layer hard to contact each other, when such an electrolyte as to connect the rewiring layer 6 with it arises along the interface between, for example, a passivation film and an organic film 10, by the moisture that the organic film 10 has absorbed, thus it can suppress corrosion of the rewiring layer 6. Hereby, even if such a material that migration or corrosion is easy to occur is used, this device can suppress these occurrence.

Abstract: PURPOSE:To strengthen adhesive force, and to prevent the exfoliation of a bonding wire from an electrode for bonding an element by plating an electrode extracting section with metal and evaporating metal on a plating layer in a process forming the electrode. CONSTITUTION:In the element consisting of components such as GaAs, a metallic layer 4 is thickly formed on a bonding section on the electrode 3 extracted from an operation region 2 on a semi-insulating substrate 1 through plating. A region except the plating section is protected by a resist film 5, the metal of the same kind as the metallic layer 4 is evaporated on the whole surface, and the resist film 5 is removed, thus forming a metallic evaporating film 6 on the plating layer through a lift-off method. Accordingly, adhesive force between the bonding wire and the electrode  can be improved because the soft evaporating layer is placed on the comparatively  hard plating layer.

Title: Probe for inter-atomic force microscope
Inventor: NAKAMURA HAJIME
IPC: G01B21/30
Filed: 1991-04-19
Abstract: PURPOSE:To obtain a probe for an inter-atomic force microscope which is high sensitivity in detection and measures in high resolution even if the aspect ratio of surface unevenness of a sample is high. CONSTITUTION:The probe is provided with a chip 1 at the tip on the projecting side of a curved plate part 2. Even when a base plate 4 on which the probe is fixed is tilted, a normal line n and a sample surface 5 orthogonally cross each other at the place where an inter-atomic force is detected. Therefore, the direction of probe displacement and inter-atomic force coincide with each other, resulting in improved detection sensitivity. In addition, the chip is kept vertical against the sample surface, so measurement is possible even with the sample whose aspect ratio of surface unevenness is high.

Title: Phenolic resin for laminated sheet
Inventor: SUZUKI TETSUAKI
IPC: C08G14/00
Filed: 1983-06-27
Abstract: PURPOSE:A phenolic resin low in a formaldehyde content and capable of giving laminated sheets of excellent tracking resistance, obtained by adding urea in a specified weight ratio to formaldehyde to the reaction system for producing a phenolic resin. CONSTITUTION:When producing a phenolic resin (e.g., tung oil-modified or melamine-modified phenolic resin) by reacting a phenol with formaldehyde, 1-20wt%, based on the formaldehyde used, urea is added to the reaction system. It is preferable that urea is added to the system just before or after completion of the dehydration reaction. It is possible to decrease free formaldehyde present in the reaction system for producing a phenolic resin and therefore to decrease free formaldehyde remaining in a laminated sheet produced from such a phenolic resin, with consequent improvement in its tracking resistance.

Filed: 1987-05-11
Abstract: PURPOSE:To stabilize the output voltage by providing a current mirror circuit to control the base current supplied to an output transistor as well as the power supplies applied to a Zener diode serving as a reference voltage supply means and a diode. CONSTITUTION:A current mirror circuit consists of transistors TR Q2 and Q3 and a common connection terminal where the emitters of both TR Qs are connected to each other is connected to an input voltage VIN terminal. The current mirror circuits Q2 and Q3 always supply a constant current as the base current of a TR Q1 regardless of the fluctuation of the input voltage VIN. As a result, a constant reference voltage level is secured and then a fixed level of the output voltage VOUT is always obtained regardless of the fluctuation of the voltage VIN. Furthermore, the current value of the current mirror circuit is decided by a fixed reference voltage level so that an extremely stabilized power supply circuit is obtained.
