Title: Improvement work for deep soft ground
Inventor: SUGI TOMOMITSU
IPC: E02D3/10
Filed: 1981-06-09
Abstract: PURPOSE:To effectively improve a deep soft ground by a method in which plural cement-based materials are prepared, by selecting the water absorbability, expansibility, and the strength of set pile to meet improving targets which are different accoding to depths, and then packed in a multi-layer form into one pipe. CONSTITUTION:For example, a casing tube 1 is penetrated into the ground 2, and plural kinds of cement-based materials 3-5, prepared to meet improving targets which are different according to depths, are charged gradually in given amounts into the casing tube 1. Afterwards, while pressing the cement materials 3-5 downwards by the forces of a screw 6 and compressed air 7, the casing tube 1 whose bottom is opened is pulled up. By this method, troubles such as abrupt generation of heat, great vibration or noise, etc., can be avoided, and the water absorbability and other characteristic properties which meet the improving targets an also be provided for each portion of different depths.

Title: Protecting device for balancing disc of pump
Inventor: KAWADA YUTAKA
IPC: F04D15/00
Filed: 1978-07-24
Abstract: PURPOSE: To prevent a balancing disc from coming into contact with a stationary vane unit, by reducing the cross-sectional area of a passage extending from a balancing unit to a suction pipe of a pump at the time of starting and stopping of the pump to raise the pressure of a balancing chamber to keep the balancing disc away from the stationary vane unit.  
     CONSTITUTION: When a multistage high-pressure centrifugal pump is run, the pressure of the discharge port 6 of the pump is transmitted to the pressure chamber 20 of a balancing disc protector 15 through a pipe 19 to elevate a piston 22 and open a leaking flow return passage 16. When the motive power supply to the pump is stopped and the discharge pressure of the pump falls below a set level, the piston 20 is moved down by a spring 25 and a piston rod 23 projects into the passage 16. At that time, the pressure of the balancing chamber 9 rises but the flow rate does not greatly fall. Therefore, the gap between the balancing disc 1 and the stationary vane unit 7 does not become extremely small. The disc is thus prevented from coming into contact with the stationary vane unit.

Title: Rotary angle detector
Inventor: SUZUKI KATSUNORI
IPC: G01D5/34
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To accurately obtain an absolute output in a small size by providing a mechanism having a light emitting unit and a light receiving unit to change transmittance in response to a rotary angle between the emitting unit and the receiving unit. SOLUTION: A disc 3 is mounted at an oscillating shaft 2. The disc 3 is coated, for example, on a glass board with Cr, Nr or the like variably in a thickness so that transmittance is linearly changed. The disc 3 is sandwiched between a light emitting unit 4 and a light receiving unit 5. As the emitting unit 4, a semiconductor laser or the like is, for example, used, a lens system is added as needed, and as the receiving unit 5, a photodiode or the like is used. A light emitted from the unit 4 is passed through the disc 3. Then, its transmittance is attenuated as predetermined according to a position of the disc 3. Thereafter, the light is incident to the unit 5, which outputs an output signal responsive to its transmitted light amount. When the disc 3 is rotated, the transmitted light amount is changed, and the output signal of the unit 5 is also similarly changed, and hence it can be detected at a rotary angle position.

Abstract: PURPOSE:To obtain a device which causes no error and is high in its accuracy, by deriving mean reference weight by adding goods within a range causing no error, from both temporary mean reference weight and resolution of a scale, deciding the number of goods to be added next, furthermore from said mean reference weight and resolution of the scale, and repeating said process. CONSTITUTION:This counting scale is constituted so that temporary mean reference weight is derived by measuring a known small number of goods, and also a maximum effective measuring number which causes no error even in case of rounding a decimal point or below is derived from its temporary mean reference weight and resolution of a scale. Subsequently, mean reference weight is derived by measuring the goods being less than this maximum effective measuring number, and also the mean reference weight is derived again by deriving the maximum effective measuring number which causes no error even in case of rounding a decimal point or below, from said mean reference weight and resolution of a scale. In this way, when processing for deriving this mean reference weight is repeated several times, accuracy of the mean reference weight is elevated, the number to be measured exactly is increased, and goods are counted within its number.

Filed: 1988-04-14
Abstract: PURPOSE:To miniaturize a device and to form a high quality image by providing a slit having a prescribed slit width on an original supporting member in order to limit the exposing area of an image carrier. CONSTITUTION:The slit (a) having the prescribed slit width is provided on the original supporting member 3 to limit the exposing area of the image carrier (photosensitive drum) 6. Thus, when an original optical image is formed and exposed on the image carrier, its luminous flux is limitted by means of the slit (a); moreover, the exposing area of the image carrier contracts to decrease a difference between the optical path lengths, which is caused by the form of the image carrier. In this case, since the slit (a) is provided on the original supporting member 3, a special member forming the slit is not needed. In addi tion, since the slit (a) adheres to the original, an illuminating light passes through between them to scan the original.

Title: Electronic clock
Inventor: HASUMI YUICHI
IPC: G04C3/00
Filed: 1993-03-26
Abstract: PURPOSE:To reduce damage and wear due to dynamic disturbance retention while maintaining retention force to some extent by retaining the dynamic rotary disturbance force transferred from the system of electronic clock hands to an electromechanical converter with a worm gear formed by the worm at a specific lead angle. CONSTITUTION:A rotar 1 and a worm 2 are directly coupled coaxially and a lead angle r of the worm 2 is formed to be 13 deg.-45 deg.. A second wheel 3 corresponds to a worm gear and transfers turning force to the system of electronic clock hands via an intermediate gear 4, etc., where transfer efficiency is improved as friction coefficient is reduced but the improvement is not remarkable when the lead angel is equal to or more than 13 deg.. Then, when the lead angle is, for example 15 deg., the transfer efficiency from the worm gear to the worm 2 is approximately 80% and the upper limit of the lead angle is 45 deg. in terms of the characteristics of the worm gear. On the other hand, when the worm gear utilizing automatic throttling is used for a train wheel system, turning force can be retained but transfer efficiency is approximately 50%. Therefore, by using the worm 2 with a lead angle of 13 deg.-45 deg., the transfer efficiency can be improved by approximately 30%, thus reducing the friction in the train wheel system and the damage and friction of a train wheel bridge, etc., due to retention of disturbance.
