Title: Npn type bipolar transistor
Inventor: KUWAGAKI MAMORU
IPC: H01L29/165
Filed: 1988-09-24
Abstract: PURPOSE:To obtain an NPN type bipolar transistor with a high current amplification factor by making an emitter region a specified non-monocrystalline semiconductor. CONSTITUTION:The emitter region 22 of an NPN type bipolar transistor is composed of non-monocrystalline semiconductor expressed by Si(1-x-y)CxAsy (where x+y<1, 0.05<=x<=0.20, 0.05<=y<0.40), that is, As is contained as a constitution element. As a result, an undesirable interface state is hardly caused between a base region 6 and the emitter region 22. Even if it is generated, the level is very low, so that an extremely large current amplification factor can be obtained as compared with conventional NPN type bipolar transistors.

Title: Call control system of exchange
Inventor: YANO MITSUMASA
IPC: H04M3/42
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To regulate an incoming call by the will of a subscriber and to notify the subscriber of the incoming call during incoming call regulation. SOLUTION: A deciding part 4 decides whether or not to regulate an incoming call with respect to a call from a caller's terminal 40 to a receiver's terminal 30 by referring to an incoming call regulation time table 301, and when incoming call regulation is consequently performed, a call regulation processing part 5 does not connect the call to the terminal 30 but connects the call to a voice responding device 12 and notifies the caller of the terminal 40 that the call can not be answered. At this time, the part 5 stores the caller's number of the terminal 40 and an incoming call regulation end time in a caller number storing part 7. When the incoming call regulation end time stored in the part 7, a call connecting part 8 generates a call to the terminal 30 and connects the terminal 30 and a voice notifying device 13.  The device 13 notifies the terminal 30 of the caller's number of the terminal 40 by voice. The subscriber of the terminal 30 knows the caller's number of the call arriving during the incoming call regulation according to this notification.

IPC: C03C25/42
Filed: 1985-10-28
Abstract: PURPOSE:To bend an optical fiber even a large angle without breakage by fixing an extremely thin piece of metal in the outer peripheral surface of the optical fiber by making it strike on and stick into the surface with the pressure of gas along with ceramic powder. CONSTITUTION:The pulverized body of ceramic coated with metallic fine powder 3 is fixed in the external surface 2 of the optical fiber coated with a material which serves to protect the optical fiber. The ceramic pulverized body is coated with metallic fine powder of alloy steel such as stainless steel and fixed normally almost at right angles. In this case, a spark is generated at a point 52 by a metallic wire 4 by feeding electricity and an extremely fine piece produced by the spark is rapidly cooled instantaneously by being exposed to cooling gas 5. Extremely fine ceramic powder is dropped from a supply port 6 by a small constant amount at every time and molten metallic extremely fine pieces are supplied to obtain the ceramic fine pulverized body coated with the metallic fine powder; and it is made to stick into the external surface of the optical fiber under the pressure of injection and can be fixed.

Title: Fuel inlet
Inventor: KIDO TSUGUO
IPC: B60K15/04
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a fuel inlet which does not increase the cost required to mount it in a vehicle body in a relatively movable manner, and which has a simple structure. SOLUTION: This fuel inlet 10 is provided with a substantially outer-tube- shaped flange part 12, not as a separate body but as an integral body, made by radially extending an end edge 11b on the side where a filler cap C is screwed in and then axially folding it back. When the fuel inlet 10 is press-fitted from the side of a fuel tank, into a fuel-inlet support hole 15 provided in a vehicle body B, it is fixed with the flange part 12 in pressure-contact with the fuel-inlet support hole 15. Because the flange part 12 is formed by extending the fuel inlet 10 itself, the number of component items is not increased and a process for assembling them is not necessary. The cost can be reduced as compared with causes where a conventional cylindrical cover is used, and the structure is simplified.

Abstract: PURPOSE: To easily and economically produce a carboxylic acid methylester in high yield by adding a specified amt. of methanol at specified temp. to a mixture of >5C mono or dicarboxylic acid and a catalyst for the reaction.  
     CONSTITUTION: A satd. or unsatd. straight-chain or branched mono or dicarboxylic acid having ≥5 carbon atoms in the molecule is allowed to react with an excess amt. of methanol in the presence of an acid catalyst to obtain a carboxylic acid methylester. In this process, methanol at 100 to 150°C (lower than the boiling point of the ester to be produced) is added by about 1 to 6 mol., especially 2.0 to 5.0 mol., to a mixture of carboxylic acid (e.g. n-heptanoic acid) and a catalyst (especially concentrated sulfuric acid is preferably used by 0.1 to 3 g per one mol. of the carboxylic acid) per 1 equiv. of the carboxylic acid. Then the reaction is carried out to obtain a carboxylic acid methylester (e.g. n-heptanoic acid methylester).

Title: Disk data reading method and disk reproducing device
Inventor: SHIOZAWA JUN
IPC: G11B19/28
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a disk reproducing device, which has a shock-proof memory, during a disk data reading. SOLUTION: In the disk data reading method, settings are made for a first threshold value L1 and a second threshold value L2, which is greater than the value L1 for a data amount D in a memory. When the amount D is less than the value L1, a disk rotational speed SP is set to a speed X2, which is faster than a disk rotational speed X1 during a normal reproduction, to increase the amount D in the memory. When the amount D exceeds the value L2, the speed SP is reduced to the speed X1 by inertia while the writing of the disk data to the memory continues.

An increase in the living body information value in each measured time is calculated by an increase calculating part 4 from the living body information value and the trend curve to calculate a fluctuation degree of the living body information value in a specific time before each measured time by a fluctuation degree calculating part 5.  An appearance probability of respective sleeping states is calculated by a calculating part from a combination of the increase and the fluctuation degree of the living body information value, and a state of adopting a maximum numeric value among the appearance probability of the respective sleeping states is estimated as a sleeping state of the corresponding measured time by an estimating part 8.
