Title: Construction of underground tank
Inventor: MINEGISHI KOJI
IPC: B65D88/76
Filed: 1993-03-17
Abstract: PURPOSE:To reduce the amount of soil excavation as well as the concrete volume required for a side wall and a bottom slab, and in addition, eliminate the need to remove an outer guide wall which is built outside a continuous underground wall, by connecting the top of the continuous underground wall to the external guide wall with dowel joints. CONSTITUTION:Since the top of a continuous underground wall 2 is connected with dowel joints 7 to an external guide wall 6 built outside the underground wall 2, the weight of the guide wall 6 can be added to the weight of the structure of an underground tank. Therefore, safety of the structure of the underground tank against the buoyancy of underground water can be ensured and a side wall 4 and the bottom slab 3 can be built in thickness having strength required for bearing the pressure of surrounding soil, resulting in a reduction in thickness of the side wall 4 and the bottom slab 3 and in the amount of soil excavation. As the outer guide wall 6 is used as part of the weight of the structure of the underground tank by connecting it to the continuous underground wall 2, the removal work of the outer guide wall 6 becomes unnecessary.

Filed: 1980-04-29
Abstract: PURPOSE:To prevent the generation of defective parts caused by division in a substrate having a plurality of elements with hexagonal or more sides, by providing scribe grooves made of the same material on the neighboring edges of each element. CONSTITUTION:Element forming regions 4 comprising a plurality of layers, e.g., four PNPN layers are provided on an Si substrate 1. The scribe grooves 5 are provided so as to surround the periphery of said elements and to obtain the hexagonal shape of elements after division. Said scribe grooves 5 are formed on a protecting layer of a P-N junction by forming grooves 12 to the depth reaching the P-N junction of the element by etching. Said protecting layer is formed by embedding a glass part 13 in the groove 12. Said protecting layer is also provided on a remaining part 6 in the peripheral region of the substrate. Thus the same material can be provided for the part beneath the scribe grooves 5, and the generation of breaks or cracks in the glass part 13 can be prevented at the time of division.

Title: Low nox burner
Inventor: WATANABE KATSUAKI
IPC: F23C99/00
Filed: 1983-04-04
Abstract: PURPOSE:To provide a low NOX burner which prevents the occurrence of backfire and is excellent in reliability, by constituting such that the speed of fluid flowing through a gap between a burner liner and a fuel nozzle is increased on the upstream side and decreased on the downstream side. CONSTITUTION:A one-stage nozzle 13, of which a burner consists, is formed in the shape of a cone such that it is of a large size on the upstream side and of a small size on the downstream side to provide an internal nozzle inner chamber 14, and a number of nozzle holes 26 are provided in its chamber wall. A relation size between a burner liner and the cone-shaped part of a fuel nozzle is set so that a velocity of flow in a premixture chamber is increased on the upstream side, and the velocity of flow in the premixture chamber is set to a maximum value higher than a backfire limit. Namely, the maximum velocity of flow in the premixture chamber is set to a value which is increased over the rate of flame propagation, for example, 40m/s, of backfire under the most adverse condition. This causes to prevent the occurrence of backfire as a result of backfire flame being carried away by a premixture stream, resulting in the possibility to perform stable low NOX combination.

Abstract: PURPOSE:To realize the cutting of words with a simple device, by detecting KANA  (Japanese syllabary) which is used frequently as a postpositional word out of a KANA  sentence, inserting the punctuation codes to regard a section between these codes as a paragraph and repeating the comparison until the coincidence is obtained with a stored  dictionary. CONSTITUTION:The characters ''NO'', ''WO'', ''NI'', ''WA'' and ''GA'' which are used  frequently in a Japanese sentence as the postpositional words are detected, and the  punctuation codes are added 1 at the positions before and after these detected words  for detection 2. The sections between codes are set as the paragraph candidates to be  supplied to an arithmetic part 4 via a register 3. The part 4 retrieves a storage device  part 6 with an access control 5 and then supplies it to an output candidate register 7,  and at the same time the part 4 repeats the comparison of contents between both registers 3 and 7. Then the word having the maximum coincidence with the first character of a paragraph is detected and sent to an output buffer. In case some residues e xist in the character train of the register 3, the similar process is carried out for the  residual character trains. When the contents of the register 7 is longer than that of the register 3, the character train up to the subsequent punctuation code is added to the  character train of the register 3 to be processed.

Title: Motor driving apparatus
Inventor: SAIJO HIROAKI
IPC: H02P6/06
Filed: 1990-03-09
Abstract: PURPOSE:To avoid the sudden fluctuation of a motor current caused by the interruption of feedback by a method wherein a detected current value is held at the time of the input of a driving phase switching timing signal and the detected current value is fed back as a virtual current value and the momentary interruption of the motor current caused by the driving phase switching is made not to be fed back and the current at that moment is continuously controlled. CONSTITUTION:A sample holding signal having a short pulse width is supplied to a sample holding circuit 22 at the time of switching of the driving phase of a motor coil. A motor current detected value is sampled in the rising period of the sample holding signal and the sampled value is held until the rise of the sample holding signal is finished. Therefore, a current detected value immediately before the decline of the motor current is sampled and, further, the value is held until the switching of the driving phase of the motor coil is stabilized. With this constitution, a signal having almost no level fluctuation is taken out from the sample holding circuit 22 as a current feedback value.

Title: Phase controller
Inventor: TAKAHARA HIDEAKI
IPC: G05F1/455
Filed: 1983-04-05
Abstract: PURPOSE:To control easily the revolving speed of a motor by applying an interruption to the output phase angle of a magnetic phase shifter which controls the current at a fixed level after comparing the currents of control windings with each other and setting apparently the output phase angle at an intermediate level. CONSTITUTION:The output of a square wave generating circuit 13 is applied to a saturable transformer ST via a resistance R100. The core of the ST is selected so as to attain saturation at a prescribed intermediate phase angle. Then a motor is actuated and accelerated by a fixed current to increase the phase angle. The phase of the transformer ST is compared 15 with the phases of potentials B1 and B2 which control a thyristor gate through AND circuits AND12 and 22 and an OR circuit OR100 respectively. The output of comparison is held 16. An interruption circuit 17 receives the output of the holding circuit 16 and applies the output of a setter 14 to the gates of the TR12 and 22 of a magnetic phase shifter MA to forcibly turn on these gates. As a result, the increment of the phase angle is stopped for the thyristor of a main circuit bridge (not shown in the diagram). Then the motor is controlled by the voltage of a fixed level and set easily at an intermediate speed. Such a phase controller is suitably applied to an AC electric car of a single phase.
