Title: Nuclear reactor operation area limiting device
Inventor: YAMAMOTO MASAKI
IPC: G21D3/04
Filed: 1990-03-07
Abstract: PURPOSE:To enable stable core operation by detecting a core unstable factor such as a recirculation pump trip and limiting the operation area of selection control rod insertion, etc. CONSTITUTION:When one of low-voltage detection signals are generated by recirculation pump motor bus low-voltage detectors 12A and 12B, an OR circuit 16 outputs a signal. On the output side of the circuit 16, a delay circuit 13 is installed and outputs a nuclear reactor operation area limitation request signal 18 with time delay. A nuclear reactor core unstableness monitor part 11 generates the signal 18. Selection switches 14 are installed in control rod driving operation devices 10A and 10B and only when the switches 14 are placed at selection positions, the condition of an AND circuit 17 is satisfied and an output signal 9A is sent out. Thus, the signal 18 is inputted to the selection control rod driving controller to insert a selected control rod 1; and the output of the nuclear reactor is reduced and the nuclear reactor is prevented from entering the unstable area.

Abstract: PURPOSE:To simplify the manufacturing process of a MOSFET with an LDD (Lightly Doped Drain) structure, by forming source and drain regions with high impurity concentration using a heat-oxidized insulating film on a gate electrode surface as a mask. CONSTITUTION:On the principal face of a P-type silicon semiconductor substrate 1, a gate electrode 3 of polycrystalline silicon is formed through a gate insulating layer 2 of SiO2. Using the gate electrode 3 as a mask, phosphorus is ion- implanted to form an N-type source region 4a and drain region 5a having a low impurity concentration. Heat oxidation forms an oxide layer 11 which is thicker on the surface of the gate electrode 3 of polycrystalline silicon than on the surface of the single crystalline substrate 1, and also forms side wall sections 11A of a thicker oxide layer on the side faces of the gate electrode 3. Using the oxide layer 11 as a mask, ion-implanting phosphorus in a higher concentration forms an N-type source region 4b and drain region 5b having higher impurity concentration at places spaced from the side ends of the gate electrode 3, in order to attain an LDD structure.

Overflow preventing members 4 are extended from the soldered members 3 in that portion of the commutator plate A which is a little inside the outer edge thereof. In this structure, the overflow of a bonding agent, which is used to fix the commutator plate A to a coil cylinder 5, can be prevented by the overflow preventing members 4 so that the slide surfaces 2 are never soiled with the bonding agent. When a rotor is in an unbalanced state, the overflow preventing members 4 are removed with laser beam. Thus, the balance of the rotor can be easily controlled.

Title: Draft beer server
Inventor: GOMI KATSUJI
IPC: B67D1/04
Filed: 1990-03-06
Abstract: PURPOSE:To restrain bubbling on the surface of liquid and to make accurate setting of liquid surface level possible by a method wherein a faucet connected to a draft beer barrel is supported with an elevating stand of a draft main body, and the elevating stand is made to ascend at a speed synchronized with the speed of rising in the liquid surface level of the draft beer being poured into a beer mug. CONSTITUTION:A beer mug (j) is placed on a carrying table 1c under a faucet 6 of a draft (b). As a injection switch SW1 is put on, an elevating stand 2 descends by pressure of a piston operated by carbonic acid gas, making an injection tube 61 of the faucet 6 descend into the inside of the beer mug (j), and stops at a specified depth. The draft beer is then discharged from the injection tube 61 by operation of a solenoid valve 71. As the beer mug (j) is filled with the draft beer, en opening 61a on the front end of the faucet ascends with a fixed distance kept between the opening and the surface of the draft beer in the beer mug (j), allowing the draft beer not to rise in bubble. When the beer mug is filled with the draft beer up to a specified quantity, the solenoid valve 71 closes, and thereby the ascend of the faucet 6 stops. Then a solenoid valve 9 opens, allowing additional injection of the draft beer to be made to form fine bubbles over the liquid surface.

Abstract: PURPOSE:To accelerate printing speed by a method wherein a roller determining the height of a printing head is made separable from blank at an arbitrary position on the blank. CONSTITUTION:When a carriage 10, on which a printing head 8 is mounted, is moved along a Y-rail 6 to reverse direction, a cam 16, which is rotatably journaled to the carriage 10, is rotated by nearly 1/2 turns together with the movement. Due to the eccentric action of the cam 16 during its turning period, the carriage 10 is lifted from the Y-rail 6, a roller 12 for determining the height of the printing head is separated from the blank 4 on a platen 2. A plotter carries out printing action in the order ot the movement (for printing one line) of the carriage 10, its top, its backward movement by small distance (for lifting the carriage 10), its stop, the feeding of paper, the movement of the carriage (for starting the printing of the next line).

Abstract: PURPOSE:To make functions of an image forming section and a picture read section developmental by allowing a control section to control the image forming section based on a result of picture reading by the picture read section so as to activate the image forming section and the picture read section interlockingly. CONSTITUTION:An image reader 12 is provided between a feeder section 1 and a transfer means 5. Paper is fed from a manual insertion port 11 when the image reader 12 reads a picture. In this case, a sensor 11a senses a member 2 to be recorded from the manual insertion port 11 and no print signal is outputted from a control section 14 by entering picture read execution from an input section 13. Then only picture reading is implemented without forming an image and an original from which a picture is read is discharged on a paper discharge tray 8. Conversely the print signal is outputted from the control section 14 by inputting image forming execution by the input section 13 and image forming is implemented. Two jobs of image forming and picture reading are executed regardless of one job exerted to one device in this way.

Only the SiO2 film 9 is selectively removed, with the SiNx film 8 left, and a PSG/SiO2 film 11 is formed. Then, a circular opening is formed. After an SiNx film 12 is formed, a contact hole is formed. Here, the SiNx film 12 inside the opening serves as a reaction preventive film. Lastly, Ti/Au is formed on a p-electrode 13 and AuGeNi/Pd/Au on an n-electrode 14, to act as APD.

Abstract: PROBLEM TO BE SOLVED: To reduce the required storage area in the case of conversion between Internal protocol version IPv4 and IPv6 by storing only the total of check sums of one fragment packet and each fragment packet. SOLUTION: The IPv4-IPv6 converter is provided with a checksum re- calculation means 22 that calculates a check sum in a host layer protocol header of a fragment packet whose header is converted by a header conversion means 21, sums the result to a value having already been stored and stores the sum in a check sum storage section 32. When all fragment packets reach a transmission/storage control means 23, the control means 23 substitutes the check sum in the check sum storage section 32 to a host protocol check sum of fragment packets in a fragment packet storage section 33 and transmits the resulting fragment packets.
