Inventor: IN MICHINOBU
IPC: H04L12/40
Filed: 1989-07-24
Abstract: PURPOSE:To assign an address of each station automatically by allowing each station to send an address resulting from the address received by its own station added with a prescribed addend toward a station adjacent in a direction of the termination station respectively. CONSTITUTION:Plural stations T making usual communication via a common communication line 4 are interconnected sequentially as a chain through an inter-station communication line 5 further, and a reference address X is sent to a station T1 being the start point (upper stream end) of this chain. Then each station adds a prescribed value Y to an address received from a station adjacent toward the upperstream via the inter-station communication line 5 and sends the resulting address to a station adjacent toward the downstream sequentially, and each station assigns the address received or sent as the address of the station in such a way. Thus, since the address of all the stations is decided automatically by sending the reference address X to the 1st station T1, a trouble of storing an address to each station in advance or of setting an address by an input device is evaded.

Title: Organic light emitting device
Inventor: INABA RITSUO
IPC: H05B44/00
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To emit the light for a long time by a light emitting element even in time when a scanning line is not operated by taking out accumulated electric charge from a capacitor at unlighted time by arranging the capacitor for accumulating a required electric current in respective picture elements. SOLUTION: A scanning line 12 is selected in an operation state, and when a ringing current according to luminance is allowed to flow to a signal conductor 11, a part of an electric current of the signal conductor 11 flows to a light emitting element 14, and a part charges a capacitor 15. The next scanning line 12 is selected in the next time, but when the light is emitted by being connected to the previous scanning line 12, since a counterflow preventive diode 13 is connected from the charged capacitor 15, electric charge accumulated in the capacitor 15 does not flow to an area other than a light emitting picture element area. The light is continuously emitted since a discharge current flows to the light emitting element 14 by electric charge charged to the capacitor 15 even if the other scanning line 12 is driven.

Abstract: PURPOSE:To improve spurious characteristics, by forming a pair of input electrodes and a pair of output electrodes and using one of these pairs as driving electrodes attached with auxiliary electrodes for driving with opposite phase. CONSTITUTION:Quartered-circular driving electrodes 8a and 8b and 9a and 9b are formed in opposition to both sides at an edge of a rectangular piezoelectric ceramic plate 1 in order to excite the edge mode oscillations with high efficiency. At the same time, opposite phase driving auxiliary electrode 10 and 11 opposing to each other at a side part of the edge of the plate 1 are formed. The electrode 9b is connected electrically to the electrode 11. The electrodes 8a, 8b, 9a and 10 are extended toward the other edge of the plate 1 to be used as terminals 8a', 8b', 9a', 10' respectively for connection of external lead terminals. Thus a 3-terminal type edge mode ceramic filter is obtained. This filter uses the terminals 8b' and 9a' as earths and the terminals 8a' and 10' as an input and output terminal, respectively. In such a way, the structure is different between the electrodes of the input and output sides, and one of these two electrodes serves as a driving electrode attached with an opposite phase driving auxiliary electrode.

Title: Torque limiter for paper feeding device of business machine and the like
Inventor: SHIOZAKI TAKESHI
IPC: B41J13/076
Filed: 1986-08-15
Abstract: PURPOSE:To eliminate the need for demanding high degree of dimensional accuracy and demanding various types of parts by bringing a needle into contact with the inner peripheral face of a casing and the back of a cover body, magnetizing the arbitrary part of a magnetic body, and effecting automatic center adjusting function and coping with the change of set torque. CONSTITUTION:When two or more sheets of paper are fed, a rotary shaft 1 is rotated in the same direction as a rubber roller R1 on the upper step part, the supporting member 2 of planetary gears 3 which is fixed to and supported by the rotary shaft 1 is also rotated in the same direction, and, accompanying with this, the planetary gears 3 and needles 4 are also revolved in the same direction. At this time, since a frictional rotation torque is not transmitted from the rubber roller R1 to R2, the rubber roller R2 is rotated in the same direction as the rotary shaft 1 due to the attraction between a magnetic body 11 installed on a cylinder body 5 and a hysteresis plate 10, discharging unnecessary sheets of paper. Hereupon, by partially magnetizing the magnetic body 11 in line with a desired torque, the device can cope with various needs. Also, by bringing the needles 4 into contact with the annular step part 14 of the casing 8 and the back of a cover body 12, an automatic center adjusting function can be effected.

Title: Manufacture of semiconductor device
Inventor: FUKUSHO TAKASHI
IPC: H01L21/28
Filed: 1994-07-23
Abstract: PURPOSE:To prevent the interface state density of a semiconductor substrate from being erased insufficiently when hydrogen is occluded by a barrier metal by a method wherein the barrier metal is sintered under a specific value or lower of pressure. CONSTITUTION:The pressure at a sintering operation is set at 760Torr 0.10MPa or lower and 10<-2> to 10<-4>Torr ( 1.33 to 0.01P). Then, the hydrogen occlusion property of a barrier metal 6 is lowered. In the case of a temperature of 400 deg.C, the hydrogen concentration under normal pressure is at 10<19>cm<-3>. When the pressure is lowered down to about 10<-2> to 10<-4>Torr, the hydrogen concentration is lowered to about 10<15>cm<-3>. When the hydrogen occlusion property of the barrier metal 6 is lowered and the barrier metal is sintered, the amount of hydrogen which is seized by the barrier metal 6 is reduced. As a result, the hydrogen which reaches the interface between a semiconductor substrate 1 and a gate insulating film 2 and which contributes to the extinction of an interface state density is increased. Consequently, the dark current can be reduced, and the threshold voltage can be stabilized.

Filed: 1987-07-31
Abstract: PURPOSE:To prevent a telephone set in the same group from starting to ring simultaneously to a calling signal sent from a main equipment by generating a calling sound in the beginning when the number of the times of calling from a main equipment is coincident with the set number of the time of calling. CONSTITUTION:The input of an operation key 8 is executed so that the preset value of a counter 7 of telephone sets 1a and 1b can be '1.' The key 8 is operated so that the preset value can be '2,' by telephone sets 1c and 1d. In the telephone sets 1a and 1b, when a calling signal S11 is sent from a main equipment 2 to a decoder 4, the counter 7 operates a driving circuit 5 since the preset value '1' and the number of the times of the calling signal sent from the decoder 4, which is '1,' are coincident. In the telephone sets 1c and 1d, the number does not reach the set number of the times by a first calling signal S11, and therefore, the driving circuit 5 is not operated. When a second calling signal S12 is inputted to the decoder 4, a calling sound is generated from a speaker 6.
