Title: Composite structural screw for injection molding machine
Inventor: NAKANO KAZUNORI
IPC: B29C45/60
Filed: 1987-10-02
Abstract: PURPOSE:To enable injection molding of a high wear resistant material such as ceramics or metallic powder by improving capacity of a screw, by applying the optimum material to each part of the screw. CONSTITUTION:A composite cylindrical material is of a composite where the external circumference B is comprised of a hard alloy superior in wear resistance and corrosion resistance and a core metal part A is comprised of a steely material possessing strength and tenacity necessary for a screw. The hard alloy B is joined firmly to the core metal part A by making use of shrinkage of a biscuit body of the hard alloy, in a composite structural and cylindrical material. Although a material for the screw is made by combining the composite cylindrical materials, the hard alloy (part B) superior in corrosion resistance is used for a part X1 (part L1) where the screw is damaged through corrosion mainly due to resin. A hard alloy (part C) which is superior in strength and tenacity though it has a little lower hardness is used for a part X2 (part L2) where loads such as the corrosion and wear are comparatively light and a high- hardness hard alloy (part D) is used for a part X3 (part L3) where wear due to the resin causes trouble. Combination of materials each in a longitudinal direction can be selected in accordance with a kind or a degree of the damage which is received by the screw at the time of use of the screw.

IPC: G01P5/22
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To measure blood flow continuously, stably and nonintermittently without requiring a strict calibration work by operating the current velocity based on the distances between a plurality of magnetic detection means disposed at different positions in the downstream of a fluid to be measured and detection outputs therefrom. SOLUTION: A field generator 3 disposed in the upstream of blood flow 5 generates a field of predetermined strength substantially perpendicularly to the blood flow 5 and magnetizes the blood flow. Magnetic sensors 1, 2 are disposed in the dpwnstream of the field generator 3 while spaced apart from each other in order to detect magnetization of the blood flow 5. Outputs from the magnetic sensors 1, 2 are delivered to a computer 4 where the velocity of the blood flow 5 is determined. The computer 4 divides the distance L2-L1 of magnetic sensors 1, 2 by the logarithm of the ratio of measurements of the magnetic sensors 1, 2 and multiplies the quotient by a time constant dependent on the components of the blood to determine the velocity of the blood flow 5 which is then presented on the screen of a display or recorded on a recorder.

Title: Read-only memory circuit
Inventor: SHIRATO TAKEHIDE
IPC: G11C17/12
Filed: 1986-10-20
Abstract: PURPOSE:To obtain a large capacitance with a small area by constituting a circuit in which a channel (p) transistor and a channel (n) transistor are corresponded with either one of two binary values respectively. CONSTITUTION:When a word line W1 and a bit line B1 go to high voltage levels to select the channel (n) transistor TN1, the gates of the channel (p) transistors TP1 and TP2 go to low voltage levels to turn on the transistors TP1 and TP2. However, since their sources are high voltage power sources VDD and B1 is at a high voltage level, no current is conducted. The gate of a TN4 is at a low voltage level, and the TN4 is turned on. When the TN1 is turned on, a current is conducted from the B1 at a high voltage level to a low voltage power source. Hence the B1 changes from a high voltage level to a low level. That is read out of an output. In such a way each transistor in a CMOS gate array is effectively used to obtain a semiconductor device with highly integration and the large capacitance.
