Title: Evaluation apparatus for end-face strength of semiconductor wafer
Inventor: HIRAHARA SEIJI
IPC: G01N3/30
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus by which the end-face strength of a semiconductor wafer can be evaluated with good reliability. SOLUTION: A guide body 4 which guides the drop movement of a plumb hob 5 is coupled and fixed to a support frame 3 which is fixed to a base 2. A wafer holding stand 15 which holds a semiconductor wafer 1 vertically is arranged and installed so as to be movable in the X-direction with reference to the base 2. The wafer holding stand 15 is positioned by a stopper 33. The center position on the tip end face of the semiconductor wafer 1 is positioned just under the plumb hob 5 which is dropped along the guide body 4. A chain 8 is stretched between a driving wheel 6 and an idler wheel 7, and it goes around between both wheels 6, 7 in the up-and-down direction. When a roller support member 17 which is coupled to the chain 8 is moved upward along the guide body 4, the plumb hob 5 is supported by a roller 16 so as to be conveyed upward.  When the roller support member 17 converts its movement direction to its U-turn direction from its upward movement, the plumb hob 5 is detached from a roller 16 so as to be dropped.

Title: Composite optical fiber and its combining method
Inventor: WATANABE SHIGEKI
IPC: G02B6/24
Filed: 1982-03-31
Abstract: PURPOSE:To combine optical fiber efficiently and surely by disposing a heating body between the fiber while the optical fiber to be joined is held disposed adjacently in parallel with each other, moving said body relatively in the axial direction of the optical fiber to heat and remove the sheath, and pressing the part after the passage of the heating body successively thereby joining the fiber under pressure. CONSTITUTION:To join two pieces of optical fibers F1, F2, the two fibers F1, F2 are first disposed and set in the opening of U-shaped guide recesses 6, 6. Then, the sheaths of both fibers F1, F2 are pressed to each other over the range of roughly a length (l) in the axial direction. In this state, a heating bar 9 is disposed between the two clads 2 and 2, and the bar 9 is moved in an arrow a1 direction. Then, the sheath parts in contact with the bar 9 are melted by heating and are expelled by the bar 9. The parts after the passage of the bar 9 are pressed to each other by means of elastic springs 7... and are thus joined under pressure. Thus, the fibers F1, F2 are pressed to each other right after the sheaths are melted by heating, whereby the sheaths of the parts where the bar 9 has passed in contact therewith are finally joined to each other to one body.

IPC: F24F5/00
Filed: 1990-03-05
Abstract: PURPOSE:To improve the appearance by fixing the above device so that the rear of the unit is in contact with the outer wall of a building by providing a suction port to a ceiling panel and providing a blowoff port to the lower parts of both of or either one of a front panel and a side panel. CONSTITUTION:The air sucked from the suction port 3 of a ceiling panel 2 by a fan 9 passes through a heat exchanger 8 to be subjected to heat exchange and further flows through the fan 9 to be blown off into a lower blowoff air chamber 16. The air blown off forwardly, leftwardly and rightwardly is blow off to the outside of an outdoor unit main body 1 from blowoff ports 17, 18. The air blown off rearwardly passes through the rear air passage generated because the fan 9 is mounted so as to be eccentric forwardly to be blown off to the outside from the blowoff port 18 and a part of the air blown off in a just-under direction is bent in many directions by the bottom surface of the outdoor unit main body 1 to be blown off to the outside from the blowoff ports 17, 18 in three directions. Since no suction or blowoff port is provided to a rear panel 6, even when the rear panel 6 is fixed in contact with an outer wall 21, no effect is exerted on the flow of air.

Title: Full-wave rectifying circuit
Inventor: OGAWA ATSUSHI
IPC: H03D1/18
Filed: 1982-03-31
Abstract: PURPOSE:To eliminate the deterioration of the output voltage against an input voltage with a simple structure by supplying input signals to the bases of the first and second transistors in reverse phase to each other and constructing to match with the voltage of an output terminal to the higher base voltage. CONSTITUTION:An input signal which is supplied to an input terminal 21 is supplied to the base of a transistor Q1 as it is, while the signal is inverted through resistors R11, R12 and an inverting amplifier 25, and then supplied to the base of a transistor Q6. Since the emitters of transistors Q1, Q2, Q6 are connected commonly to each other, when either base voltage of the transistors Q1, Q6 becomes higher than the base voltage of the transistor Q2, i.e., the output DC voltage, a collector current flows through the transistor Q3, thereby operating to match the voltage of the output terminal 24 to the higher value of the base voltages of the transistors Q1, Q6. In other words, a full-wave rectified signal is outputted from the output terminal 24.

Filed: 1984-03-22
Abstract: PURPOSE:To drop the contained object through a back face opening while to limit careless movement by providing a position regulating member for shielding the back face opening when opening the container while pressing the contained object against the mounting face when closing the container. CONSTITUTION:When containing an object 22 in a box body 3, a handle 24 is first pulled to draw out the box body 3 and open. Consequently, the bottom face 23 as the mounting face of the box body 3 is brought horizontal to be mounted with the object 22. Since a position regulating body 15 made of shrinkable and movable resilient mesh body is shielding the space in the box housing 7 obliquely, the object 22 will never bounce in the box body 3 nor fall out through the opening 13. While when rotating the box body 3 upward and closing, the position regulating member 15 will cover the object while stretching and press against the bottom face 23 thus to limit the motion of said object 22.

IPC: G06F11/20
Filed: 1990-03-07
Abstract: PURPOSE:To allow the contents of a main data base and a sub-data base to synchronize with each other at the time of switching an on-line system by allowing a terminal side to receive transaction serial numbers from the sub-on-line system, compare the received numbers with transaction serial numbers included in the terminal and automatically resend the transaction of the difference. CONSTITUTION:When a shop system terminal side 31 is switched from a main on-line system 34 to the sub-on-line system 36 due to a failure or the like in the system 34, synchronism checking information 45 stored in an external storage device 38 for the system 36 is transmitted to a distributed processor 42. The processor 42 compares synchronism checking information stored in an external storage device 32 with the received information 45. When the transaction of a difference exists, the differential transaction data are extracted from an external storage device 33 and inputted to the system 36. For instance, the final transaction serial number of terminal number 01 is '10' on the system 36 side through the number is '12' on the processor 42 side, so that the transactions of transaction serial numbers 11, 12 are inputted to the system 36. Thus, the contents of the main and sub-data bases can be synchronized with each other.
