Title: Extended dc power source formed of dc/dc converter
Inventor: SAKAI YOSHINORI
IPC: H02M3/155
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts used in all circuits and the size of a system. SOLUTION: A master circuit 10m is composed of a synchronous commutating type DC/DC converter 4, formed with only a constant-voltage control circuit 5. A slave circuit 10s is composed of a DC/DC converter 6 which involves a constant current control circuit 7. If load is small, current outputted from the slave circuit 10s is fed back to an input power source through the synchronous commutating type DC/DC converter 4, a constant output voltage is maintained, and constant current operation is controlled by the slave circuit 10s. The master circuit 10m requires only the constant-voltage control circuit 5 and the slave circuit 10s requires only the constant-current control circuit 7, thus it is possible to reduce the number of parts for size reduction.

Title: Semiconductor integrated circuit
Inventor: KOMURASAKI HIROSHI
IPC: H01L29/786
Filed: 1998-12-14
Abstract: PROBLEM TO BE SOLVED: To reduce electrical signal losses by short-circuiting an N+ region and a P+ region formed adjacent to a channel doping region right under a gate with a second electrode, isolating them from other elements by a filled shield, and not connecting the second electrode to a fixed potential. SOLUTION: An N+ region 12 and a P+ region 13 are formed adjacent to a channel doping region right under a gate. Further, a filled shield 14 for isolating the regions 12 and 13 from other elements such as a MOSFET and gate capacitance, is formed of polysilicon. According to this constitution, the regions 12 and 13 are insulated from each other by SiO2 and thus parasitic resistance between a capacitive element and a ground increases remarkably. Hence, a parasitic capacitance can be made extremely small. Therefore, electrical signal losses can be reduced.

Abstract: PURPOSE:To obtain a coated stimulable phosphor excellent in luminance, emission life, and their persistence by converting a feed gas and/or a reaction gas into a plasma and feeding it onto a phosphor powder to form a coating film on the powder. CONSTITUTION:While the inside of a reaction pipe 2 is kept at a vacuum of 0.05-5Torr through an exhaust pipe 21, a reaction gas (e.g. oxygen) is fed into the reaction pipe 2 through a feed pipe 11. The gas is converted into a plasma when it passes through a region where a high-frequency coil 3 is arranged, and then fed through an open end 12 onto a phosphor powder 4. Separately, a carrier gas (e.g. Ar) is introduced into a raw material liq. (e.g. a metal hydride) 6 and is fed together with a vaporized raw material through a feed pipe 51 and a filter 22 onto the powder 4. Thus is carried out a plasma CVD wherein a free radical or plasma generated in the plasma formation decomposes the raw material gas and reacts with it on the powder, forming a coating film on the powder and giving a coated stimulable phosphor.

Filed: 1991-12-26
Abstract: PURPOSE:To attain a quick reply to an incoming call by controlling an incoming call number optionally in response to a reply number replied with an incoming call when the incoming call comes from a telephone network to an extension subscriber. CONSTITUTION:When a call comes to an extension subscriber 1 from a telephone network 5, a CPU 9 detects it and a busy state detection circuit 6 detects whether the subscriber 1 is busy or idle. As a result, when the subscriber 1 is idle, the CPU 9 detects number of call units replied at present and number of call units not replied yet by a replay state call unit detection circuit 7 and a non-reply call unit detection circuit 8 respectively with respect to preceding arrival of calls to the present arrival of the call to the subscriber 1 and reads the reply enable call unit registered already by the subscriber 1. Then, the CPU 9 compares the reply enable call unit number with the sum of the number of call units replied at present and number of call units not replied yet and allows the arrived call to reach the subscriber 1 when the reply enable call unit is over the sum of the number of call units replied at present and number of call units not replied yet. Moreover, the CPU 9 allows the arrived call to reach a specific extension when the reply enable call unit is equal to or less than the sum of the number of call units replied at present and number of call units not replied yet.
