摘要： PURPOSE:To improve an operation property in the case of printing by a method wherein a printing part is installed to a rear part of a printer body to make a printer with automatic paper feeder, and the combination device is so constructed as to be capable of disposing an information processor body on a printing paper housing part. CONSTITUTION:When an information processor body is set by forming integrally an inclination pin 36 on a printer upper case 25 of a printer with automatic paper feeder 9, the inclination pin 36 is engaged with a positioning hole 37 provided to a body under case 7 and a guide hole 39 of a body shutter 38, and the body is rotated by centering a fastening part 40 as an axis to open a body opening and closing window 41. Then, transfer of an optical signal between signal converters 42 becomes capable of being performed. At the same time an inclinable pin 43 provided to a printer upper case 25 is pushed by an empty weight of the information processor body, and a shutter 44 is rotated by centering a fastening part 46 as an axis to open a printer opening and closing window 47. Therefore, transfer of the optical signal between a printer control substrate 48 and the signal converter 42 becomes capable of being performed. Thereby, a printing signal is sent to the printer with automatic paper feeder 9 from the information processor body and printing becomes capable of being performed.

摘要： PURPOSE:To obtain a vacuum cleaner for enabling optimum operation to be automatically performed, by selecting optimum control patterns from control patterns stored in a storage section based on the pressure detection value of a filter rear-section. CONSTITUTION:When an operation switch 18 is turned ON, then a brushless DC motor is started by a microcomputer 13. When rise is executed up to given rotational frequency, then a starting process is completed, and a cleaned surface and the loading degree of a filter are detected. In other words, based on signal from a pressure detecting circuit 24, a process for discriminating what the cleaned surface is, and a process for discriminating the loading degree of the filter are performed. Then, based on the result of the process of discriminating the cleaned surface, a function related to the cleaned surface of a function table 22 is selected by a switch 23, and based on the result of the process of discriminating the loading degree of the filter, speed command N is obtained from the function table 22.

摘要： PURPOSE:To prevent an excess rotation of a vacuum cleaner by using an inverter-controlled brushless DC motor for the cleaner, controlling an open loop voltage, and correcting a speed command from the actual rotating speed. CONSTITUTION:An inverter controller 10 obtains a DC voltage Ed through a rectifier 15 and a smoothing condenser 16 from an AC power source 14, and drives a brushless DC motor 9 through an inverter 20. A controller for controlling the speed of the motor 9 is composed of a microcomputer 13, a pole position detector 12 by a Hall element 11, a load current ID detector 17, a base driver 19, a speed instructing circuit 18, etc. Thus, the microcomputer 13 has an upper limit processor, and the motor 9 is controlled by the microcomputer 13 to prevent its rotor from damaging due to its centrifugal force and a fan from breaking due to its centrifugal force.

摘要： PURPOSE:To raise the reliability and operability of construction work by a method in which a key-shaped anchor rib is welded to a steel plate, and a side-threaded reinforcing bar coupler is attached to a threaded reinforcing bar and welded to a recession while regulation an installing error. CONSTITUTION:A key-shaped anchor rib 11 is welded to a steel plate 4, and a side-threaded reinforcing bar coupler 7 is attached to a threaded reinforcing bar 6. The coupler 7 is welded to the recession of the rib 11 while regulating an installing error, horizontal beams are set, and concrete is placed. In this case, the welding points of the coupler 7 and the rib 11 are four. Since the setting error of the reinforcing bars and the anchor system can be easily absorbed, the reliability is enhanced and the setting operation of reinforcing bars and the placing operation of concrete can be simplified.

摘要： PURPOSE:To enable semiconductor wafers to be inserted into a carrier efficiently by a method wherein the surface of bottoms comprising a part of the carrier is provided with engagement parts with wide opened slits so that the semiconductor wafers may be vertically inserted into the slits to be obliquely surface-held by the oblique sides of engagement parts after they are inserted thereinto. CONSTITUTION:One side of engagement parts 5 is formed into vertical surface and the other side is formed into oblique surface making an angle of theta2 with the vertical surface as shown in the figure while the depth of engagement parts 5 is made gradually shallower from left side to right side due to the specified bottom height h1 of the engagement parts 5. The degree of shallowness is decided in consideration of oblique angle of the bottoms 3 as well as the numbers of semiconductor wafers 2 to be contained. Besides, the other height h2 of bottoms 3 may be around 5mm. In such a constitution, the opening width of engagement parts 5 can be increased so that the semiconductor wafers 2 may be easily inserted from above into the engagement parts 5 as shown by the imaginary lines.

摘要： PURPOSE:To simplify a structure while enhancing workability, by forming a hermetically closed space to the outside of bellows so as to surround the same and pressurizing or evacuating said space to perform a pressure resistance/ leakage test. CONSTITUTION:The connection part of the disc shaped protective ring 9 provided to the outside of bellows and a cylindrical protective cover 10 is welded to impart air-tightness and a gasket 6 is inserted in the gap part and clamped and sealed by a clamp plate 17 and a clamp bolt 19 to form a hermietically closed space to the outside of the bellows 6 while a test plug 18 is provided to the protective cover 10 to pressurize or evacuate said hermetically closed space. By this mechanism, because a worker is released from entering an atomic reactor receiving vessel under a highly radioactive condition and a guard pipe becomes unnecessary, work becomes easy and the structure of a test apparatus can be simplified.
摘要翻译：目的：为了简化结构，同时提高可加工性，通过在波纹管的外侧形成一个气密封闭的空间，以便围绕它，并对所述空间进行加压或抽空以进行耐压/泄漏试验。构成：将设置在波纹管外侧的圆盘形保护环9和圆筒形保护盖10的连接部分焊接起来以赋予气密性，并且将垫片6插入间隙部分中，并由夹板17夹紧和密封以及夹紧螺栓19，当将试验塞18设置在保护盖10上以对所述密封空间加压或抽空时，形成到波纹管6外部的非闭合空间。通过这种机制，由于工人在高度放射性条件下被释放而不能进入原子反应堆接收容器，并且不需要保护管，所以工作变得容易，并且可以简化测试装置的结构。
