Title: Mos semiconductor device and manufacture thereof
Inventor: NAKAHARA MORIYA
IPC: H01L21/822
Filed: 1989-07-10
Abstract: PURPOSE:To make it possible to miniaturize a device, to suppress the dispersion of resistance values and to achieve a high speed by using polycrystalline silicon for a resistor element. CONSTITUTION:A P-wall region 2 and an N-well region 3 are formed in a P-type semiconductor substrate by using a twin-well forming technology. A field oxide film 4 is formed by using selective oxidation technology. Then a gate oxide film 5 is formed. Channel ions for controlling a threshold voltage value are implanted. Thereafter, non-doped polycrystalline silicon 6 is formed on the entire surface. In order to obtain a required high-resistance element, e.g. arsinic ions are implanted. A pattern is formed so as to obtain the high concentration for the impurities in the polycrystalline silicon film 5 other than the high-resistance element part. Thereafter, e.g. arsinic ions are implanted. Since a region which is to become the resistor element is covered with a silicon nitride (SiN) film 7, the arsinic ions are not implanted. Therefore, this part is not made to be a high concentration region. Since the ions are implanted into non-doped polycrystalline silicon and the resistor element is formed, the required resistance value is obtained by arbitrarily changing the dosing amount of the ion implantation.

Title: Aseptic food processing apparatus and method
Inventor: JIEEMUZU II HOWAITO
IPC: B65B55/14
Filed: 1985-08-09
Abstract: A greatly improved aseptic processing apparatus and method for pumpable foods is provided which gives accurate, uniform aseptic cooking conditions (e.g., time, temperature and pressure) while at the same time preserving the integrity of particulates in the food product. In preferred forms, the apparatus includes a reciprocating piston food pump which generates a continuous product stream at a substantially constant nominal pressure. This stream is fed to a heat exchanger in order to elevate the temperature of the product, whereupon the stream passes through a holding tube to complete the aseptic cooking process. A metering device such as a rotary pump is located downstream of the holding tube for creating a substantially constant flow rate of product from the apparatus. Use of the downstream metering device in conjunction with an upstream constant pressure pump permits attainment of even, relatively high system pressures which in turn facilitates accurate temperature control and eliminates localized internal steam flashing which can deleteriously affect product quality. By virtue of the present apparatus and method, aseptic processing of low acid heterogeneous food products such as stews and chilies can be safely accomplished on a commercial scale.

Title: Inter-cpu communication equipment
Inventor: TACHIBANA TATSUTO
IPC: G06F15/177
Filed: 1990-07-05
Abstract: PURPOSE:To attain the mutual communication among the CPUs with the transmission bit data that detected a communication error with high efficiency by transmitting in duplication the same transmission bit data among the CPUs and receiving these data by each CPU while comparing the contents of bits with each other. CONSTITUTION:A data transmission means including a command transmission system 1a and a status transmission system 2b transmits in duplication the transmission data bits set by the CPU A and B to other CPUs continuously by at least two bits. Then the data transmission means compares the transmission bit data received in duplication by the reception means 2a and 1b of the CPU A and B from other CPUs continuously by at two bits with each other for each bit in order to detect a communication error. As a result, the transmission bit data can be easily produced for effective detection of the communication errors compared with the processing where the data are transmitted with addition of a parity bit. Thus the communication processing is attained between both CPUs with the transmission bit data that can effectively detect the communication errors.

Title: On-site placed concrete pile with built-in steel frame
Inventor: MAEDA SHOZO
IPC: E02D5/34
Filed: 1993-07-16
Abstract: PURPOSE:To reinforce a pile, simplifying execution, by constituting a concrete pile of a steel reinforcement cage inserted into a hole drilled under the ground and a concrete, and inserting a steel frame into the center part on the sectional surface of the concrete in the pile head part. CONSTITUTION:A concrete pile 1 to be struck at a site is constituted of a steel reinforced cage 2 inserted into a hole drilled under the ground and a concrete 3, and a steel frame 4 is inserted into the center part on the sectional surface of the concrete 3 at the pile head part. Before the root cut through the reverse striking construction method, a pillar consisting of an underground structure body is constituted, and a steel frame pillar 5 having the length reaching the foundation is installed on the pile 1, and a part of the pillar 5 is utilized as the steel frame 4 of the pile 1. The bending resistance of the pile 1 becomes large when the axial force is a compression force, while the bending resistance becomes small when the axial force is a tensile force. Since the steel frame 4 which is burdend with the tensile force is built in the concrete 3, the resistance force of the whole pile 1 becomes the sum of the resistance force of the concrete pile 1 and the resistance force of the steel frame 4, and the large bending resistance force is secured even at the position where the tensile force increases.
