Title: Method for receiving liquid from movable tank
Inventor: YAMADA TADASHI
IPC: B67D7/78
Filed: 1991-01-25
Abstract: PURPOSE:To efficiently unload liquid from a tank lorry by removing air bubbles therefrom. CONSTITUTION:Pipes A1 and B1 are connected to a three-way valve 9 connected to a tank lorry 5. The one pipe A1 is connected to a transfer pump 3a and the other pipe B1 is connected to a dump tank 2. The dump tank 2 is provided in a lower position than the tank lorry 5. By the operation of the three-way valve 9, the pipe is arranged in communication with the tank lorry 5 to allow liquid in the tank lorry 5 to flow into the dump tank 2 under the force of gravity. In this way the air bubbles trapped between the dump tank 2 and the three- way valve 9 are eliminated. After the lapse of a predetermined time, the pipe A1 is arranged in communication with the tank lorry 5 by switching the three- way valve 9 and the liquid in the tank lorry 5 is unloaded by operating the transfer pump 3a. When the liquid in the tank lorry 5 is running short, the liquid therein is sent through the pipe B1 into the dump tank 2 by switching again the three-way valve 9.

IPC: G11B21/02
Filed: 1987-01-16
Abstract: PURPOSE:To reduce backlashes generated by the direction of rotation of a driving motor and to highly accurately position a magnetic head by providing needle sandwiching a shaft to travel a mobile base and a pressing spring, and fixing the rear end of the needles on the mobile base and the pressing spring also on the mobile base. CONSTITUTION:A projecting strip 10a brought into contact with the guide groove 8a of the shaft 8 disposed so as to oppose to the needle 9, is formed, and the rear end of this strip 10a of the pressing spring 10 fixed on the projecting part 3d of the mobile base 3 is brought into contact with the guide groove 8a in a similar manner as the needle 9. When the shaft 8 rotates in the direction of arrow A, the friction force between the groove 8a and the needle 9, and that between the groove 8a and the needle 9A and equal and in the opposite directions, therefore, no force acting in the direction of the normal of the shaft of a guide bar 6 occurs. Also, when the shaft 8 rotates in the direction of arrow B such as the case of the rotation in the direction of arrow A, no force that acts in the direction of the normal of the shaft of a guide bar 6 occurs, hence the magnetic head 2 can be stopped at one and the same place even when the mobile base 3 travels from the inner/output peripheral part of a storage medium to the respective opposite directions.

Title: Rainwater gutter
Inventor: HAYASHI HITOSHI
IPC: E04D13/064
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent a core layer and a covering resin from separating from each other even when they are shocked during transit, construction, etc., by providing an intermediate layer made up of a thermoplastic elastomer between the core layer and a resin layer covering the core layer. SOLUTION: The rainwater gutter 1 is comprised of a core layer 1, a covering resin layer 2 made up of a resin covering both sides of the core layer 1 and a thermoplastic elastomer provided between the core layer 1 and the covering resin layer 2. Thus by providing the intermediate layer made up of the thermoplastic elastomer, separation of the core material and the covering resin due to shock can be reduced. Use of a thermoplastic elastomer having the modulus opf elasticity in tension of 1.0 GPa or less helps reduce stress during shock concentrating between the core layer 1 and the covering resin layer 2. Furthermore, the thickness of the intermediate layer of 20 mm to 500 mm is large enough to relax stress applied during shock, and restrains cohesive failure and prevents the core layer from separating from the resin layer even if thermal expansion or contraction occurs.

Abstract: PURPOSE:To expand the capacity of a memory without the necessity of changing the design of hardware by using an access operation for plural specified addresses for the designation of the selection of a memory cell connected at the time of access with the other respective memory addresses. CONSTITUTION:A latch circuit 160 is connected to the lower four bits of an address bus 14 and higher 12 bits are decoded. When they are equivalent to 3FF, the latch circuit 160 is caused to fetch data. A decoding circuit 200 decodes a value written in it (four bits in this case) and generates a bank selection signal. The access of an address 3FF0 causes the selection of a bank number '0', and the access of an address 3FF1 does the selection of a bank number '1'. Namely, addresses 3FF0-3FFF being the specified addresses are used for the switching of a memory bank. Thus, the capacity of the memory is increased without changing the design of hardware in a computer.

Title: Corrugated-shape inspecting method for corrugated flexible pipe
Inventor: YOSHIMURA KOJI
IPC: G06T1/00
Filed: 1990-01-18
Abstract: PURPOSE:To inspect the corrugated shape of a corrugated flexible pipe automatically without contact by obtaining the characteristic quantity of the corrugated shape based on the coordinate values of the apexes with respect to the axial direction of the pipe on approximate curves in the vicinities of the coordinate values of ridge parts and bottom parts obtained on a binarized image. CONSTITUTION:The still image of a corrugated flexible pipe is picked up with a photodetector. The binarized image is obtained from this image. A corrugated profile line 8 within a suitable window 7 is obtained on the image. An intermediate line 14 between ridges and bottoms is obtained based on the average value of the maximum values and the minimum values of the ridge parts and the bottom parts of the profile line 8. The intermediate line 14 is made to be the final reference line. The profile line 8 is divided into the ridge parts 15a - 15c and the bottom parts 16a and 16b. Then approximate curves 17a, 17b, 18a and 18b in the vicinities of the coordinates of the ridge parts and the bottom parts are obtained. The values of the coordinates of the apexes 19a, 19b, 20a and 20b are computed. At this time, the effects of noises caused by minute flaws on the outer surface of the pipe and the attachment of foreign matter are negligible. Therefore, the apexes can be accurately obtained. The characteristic quantity of the corrugated shape obtained from the coordinate values of the apexes, i.e. the pitch of the bottoms and the deviation of the corrugation, are compared with the threshold value for every preset characteristic quantity. Thus, the characteristic quantity can be automatically inspected.

IPC: H03L7/06
Filed: 1989-01-18
Abstract: PURPOSE:To improve the transient response by detecting a frequency difference between an input signal and an output signal and controlling a variable frequency oscillating circuit directly so as to decrease the frequency difference when the difference is larger than a preset prescribed value. CONSTITUTION:When a frequency difference between an input signal and an output signal is a prescribed value or below, variable frequency oscillation circuit 12 similarly to a conventional circuit generates a signal with the frequency in response to a signal of phase feedback control received from the output of a phase comparator circuit 4 operated with a phase difference of both the signals via an arithmetic circuit 4 and supplies the result to the phase comparator circuit 4. When the frequency difference exceeds the prescribed value, the variable frequency oscillation circuit 12 is controlled independently of the phase difference of both the signals and varies its output frequency so as to decrease the frequency difference. Thus, the phase synchronizing circuit with excellent response characteristic against the fluctuation of the input signal is obtained.
