Title: Molecular beam growth of silicon
Inventor: HIRAYAMA HIROYUKI
IPC: H01L21/203
Filed: 1988-03-07
Abstract: PURPOSE:To enable selective epitaxial growth of silicon film singly on exposed parts of silicon by proceeding selective epitaxial growth of the silicon film by exposing the surface of a silicon substrate having a covering film by a specified method. CONSTITUTION:A silicon film is grown epitaxially by a gas source silicon molecular beam growth process selectively on a part of a silicon substrate exposed by being partly uncovered by a covering film on a silicon substrate wherein said epitaxial growth is proceeded by using disilane as a feed gas. The adsorption of dissociated disilane molecule to the surface of silicon is prompted preponderantly as compared to the surface of SiO2. It is considered, therefore, that selective growth is possible in the molecular beam growth method where gaseous disilane molecule is used. Although necessary selectivity is not obtd. at high temp., necessary selectivity is obtd. when the temp. of the substrate is low, so the process is applicable to the prepn. of a device, etc., where a low temp. process is required.

Title: Digital logic circuit
Inventor: MORI SUSUMU
IPC: H03K19/003
Filed: 1981-04-10
Abstract: PURPOSE:To avoid the breakdown of a digital logic circuit although a short circuit is mistakenly caused between an output terminal and a GND or between the output terminals, by providing a protecting circuit in which the output is set at L only in case the output terminal is forcibly set at L from the outside when the output terminal is set at H. CONSTITUTION:An output 3 is set at H and L when an input 1 is at L and H, respectively. Thus in this case, two inputs of a comparator 40 are not set at L simultaneously. At the same time, an output 41 is set at H to give no effect to the ordinary logic working. In case a terminal 3 is short-circuited to a GND while an input signal of H is applied to the input 1, an ON buffer output circuit 20 is cut off. Accordingly, no overcurrent flows through the circuit 20. On the other hand, if the terminal 3 is short-circuited to the GND while the input signal of L is applied to the input 1, the terminal 3 is forcibly set at L. As a result, the two inputs of the comparator 40 are set at L with the output 41 set at L. Thus the circuit 20 is cut off to break the overcurrent which is about to flow for the time of 10-20ns.

Title: Fuel assemblies
Inventor: KAWAMURA YASUSHI
IPC: G21C15/06
Filed: 1978-05-09
Abstract: PURPOSE: To obtain a flat output disstibution in the axial direction due to a suppresion of an output peak of a lower part, by forming a fuel assemblies so that a bypass area of a upper part of the fuel assemblies becomes wider than that of a lower part.  
     CONSTITUTION: A thickness of a upper part 2 of a channel 1 is thinner than that of a lower part 3 so that a bypass area (a cooling water area at the outside of the channel) of the upper part 2 of the channel 1 of the fuel assemblies becomes wider than that of the lower part 3. For example, the thickness of the lower part 2 is about 3 mm and the one of the upper part 2 about 2 mm. In this case, a size of the inside (arrow mark) of the upper part of the channel 1 is the same to that of the lower part. Other methods, which enlarge the area of bypass of the upper part, can be adopted. For an example, the thickness of the upper part is sized to be smaller than that of the lower part, or grooves are made at the outside of the upper part of the channel.

Title: Carrier recovery system
Inventor: TAKEDA YUKIO
IPC: H04L27/00
Filed: 1986-03-12
Abstract: PURPOSE:To recover a carrier with a high SN, and to exactly demodulate a reception signal without making large an offset voltage, by inserting a carrier synchronizing signal in the data of a service channel SC system. CONSTITUTION:A transmission data processing part 1 multiplexes the data of the SC system on a main signal, or performs a framing. The analog output of a frequency divider 4 is converted to a digital signal by a coder 5, and is inserted to the data of the SC system as the one which represents a bit of carrier information. At a reception side, a reception data is branched with a hybrid circuit 20, then being transmitted to mixer 21 and 22. When the synchronization of a recovery carrier circuit is established, the data of the SC system is recovered at a reception data processing part 7. A change-over switch 9, in stead of a loop filter 8, outputs a signal from a loop filter 12 that is the data of the SC system synchronized with a transmission carrier. Thus, since the synchronization in the recovery carrier circuit is temporarily established by a PLL loop, and next, an accurate synchronizing signal is obtained from the data of the SC system obtained by a temporarily established synchronization, and a PLL loop is constituted, the synchronization with high accuracy can be established.

Title: Substrate conveyer device
Inventor: KAKU SHIYOUICHI
IPC: B65H5/16
Filed: 1988-03-08
Abstract: PURPOSE:To prevent a substrate from overrunning in a substrate conveying device used for processing an electronic circuit board or the like, by appropriately gripping the substrate with the use of two of front and rear pawls so as to move a desired position at which it is stopped by a slider. CONSTITUTION:When a slider 30 is returned a substrate feed start position, a second pawl 51 is retained at a position where it does not interfere with a substrate 18 on stand-by. A first pawl 50 is set at a position which is required for transferring a position reference edge part of the substrate 18 to a predetermine position. An internal stopper 54 is set at a position where it can stop the pawl 51 at a position having a predetermined distance from the pawl 50. Accordingly, the stopper 54 is originally set at a position near to the pawl 51, and in the case of the leading edge reference, the stopper 54 is positioned apart from the pawl 51. When the stopper 30 starts moving, the distance between the stopper 54 and the pawl 51 decreases. When the stopper 54 strikes the pawl 51, the latter is moved away from an external stopper 57, and thereafter it advances while holding a predetermined distance to the pawl 50, and is stopped together with the slider 30.

Title: Automatic reporting device
Inventor: ITO KUNIAKI
IPC: H04M11/00
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous decision that the remaining capacity of a battery has been neglected despite of the presence of its remaining capacity by reading through a control means the generated variation curve of consumption electric energy by the vibration of a load in the case of the increase of the load to store the read result in a storage means. SOLUTION: For controlling a transmission means 4 and network controlling means 5 once a day for checking a battery 6, a control means 2 with a clock function switches over the load applied to the battery 6 from a light one to heavy one to detect the voltage variation of the battery 6 by a voltage detection means 7 and an analog-quantity quantizing means 8. Storing once the detected voltage curve in a storage means 3, the control means 2 decides whether the battery 6 has sufficient power for driving an automatic reporting device 1 or not to report the abnormality of the battery 6 to a center 9 before it becomes completely unable to drive the automatic reporting device 1.  As a result, it can be prevented that whether the lowering of the voltage of the battery 6 is caused by the actual reduction of its remaining capacity or not can not be decided to determine erroneously that the remaining capacity has been neglected despite of the presence of the remaining capacity.
