Title: Wire bonder and bonding method for semiconductor device
Inventor: KOBAYASHI HIROTAKA
IPC: H01L23/50
Filed: 1992-05-19
Abstract: PURPOSE:To provide a wire bonder and bonding method for semiconductor device in which stability is enhanced in the bonding strength between an electrode and a bonding wire when they are wire bonded by means of a heat adapter. CONSTITUTION:A heat adapter 12 has a die pad mounting part 22 and an inner lead mounting part 26 which are flush with each other, and a vacuum suction hole 32 for sucking a die pad is made at the die pad mounting part while a recess 28 is made oppositely to a suspension lead 30 at an end of the die pad. A die pad part 20 and an inner lead 24 are mounted on one flat surface and the die pad part 20 is then brought into tight contact through vacuum and wire bonded. Consequently, tight contact of the suspension lead 30 is prevented by means of the recess 28 even if the suspension lead deforms downward thus realizing tight contact between the die pad 20 and the heat adapter 12. Conduction of heat from the heat adapter 12 is also improved and vacuum is kept as it is to prevent temperature drop and to stabilize bonding strength between connecting electrode on a chip 18 and a wire.

Title: Data receiver
Inventor: AMADA EIICHI
IPC: H04L5/14
Filed: 1983-08-19
Abstract: PURPOSE:To attain efficient data transmission by providing a means storing the result of OR between a value of a buffer memory storing one bit or plural values forming the unit of blocks and a value of a buffer memory corresponding to the inputted bit into the same buffer memory. CONSTITUTION:When frame information transmitted from other terminal device is received by a receiver, the information is inputted to a shift register 202 and subject to serial/parallel conversion. When an output of the shift register 202 is a control field, 7-bit b0-b6 except a parity bit b7 are stored in flip-flops 220-226 through OR gates 210-216. A controller 208 detects amount of packet data by counting the number of reception bytes through a CRC check circuit 204 so as to generate a write address corresponding thereto. Thus, the input is stored while being ORed with an output of the flip-flops 220-226.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To enable a pseudo moving bed type operation which exhibits a high separation performance by switching a feed, an extraction positions of a material liquid to a unit packed bed at the downstream side of a circulation system at every completion of each process. SOLUTION: In a first process, an A fraction is extracted by an A fraction extraction valve 6a from a part of a liquid flowing out of a unit packed bed 6 while an eluent D is supplied via an eluent feed valve 1d. The feed of the eluent D is stopped, and the fluid in all the unit packed beds of a circulation system is circulated by a circulation pump 10. Then, a breaker 9 is closed and a B fraction is extracted by a B fraction extraction valve 4b while a material liquid (f) and the eluent D are respectively supplied from a material liquid feed valve 5f and the eluent feed valve 1d. After the fluid is circulated again, a C fraction is extracted by a C fraction extraction valve 2c from the liquid out of a unit packed bed 2. After the first process is finished, a feed, an extraction positions of the liquid are shifted by a distance of one unit packed bed towards the downstream side, a second process is started to extract the A fraction and C fraction. The operation is repeated to an eighth process. One cycle is thus completed, and the driving is returned to the first process.

Title: Developing device
Inventor: GOTO TAKAHARU
IPC: G03G15/09
Filed: 1984-07-19
Abstract: PURPOSE:To detect a density of a toner with a high reliability by inclining a detecting surface of a toner density detecting member by a specified angle against the upper face of a scraper member. CONSTITUTION:When a detecting surface of a toner density detecting member 8 is inclined greatly against the upper face of a scraper 15, when a developer 2 passes through, it is pressed moderately by the detecting surface, and the developer 2 contacts to the detecting surface in a comparatively dense state. Also, a flow of the developer 2 becomes a shape contacting to the detecting surface, and the surplus developer 2 flows so as to escape to both sides of the detecting surface, it is scarcely influenced by a change of the quantity of the developer 2 on the scraper 15, which is expected when the fluidity of the developer 2 has been brought to a very small change, and the detecting error becomes small. As for this inclined angle theta, a range of 10-45 deg. is suitable. When it is under 10 deg., the developer is pushed into a wedge-shaped area, therefore, when its fluidity is changed, an uneven density is apt to be generated, and on the other hand, when said angle exceeds 45 deg., the detecting coil surface does not always enter into a flow of the developer 2, and rather an unstable state is generated.

Abstract: PURPOSE:To shorten a development period and to reduce cost by providing a register composed of a flip flop where an initial state which is set by means of a reset signal can be altered by a control signal. CONSTITUTION:The control registers CTR is composed by using a flip flop whose set state and reset state can be switched by the control signal, and the control register CTR is initialized to the different initial state by the reset signal (r) in accordance with the state of a prescribed external terminal RES.

Title: Dielectric deterioration deciding method of range insulation winding of rotary electric machine
Inventor: KADOTANI KENZOU
IPC: G01R31/12
Filed: 1979-11-24
Abstract: PURPOSE: To prevent an accident by making the X-Y coordinates of the maximum discharging charge and a value relating to the mean discharge energy, plotting a measuring point of the winging, adding the tendency of dielectric deterioration of the winding to the residual dielectric breakdown voltage, and deciding the result.  
     CONSTITUTION: The measuring point of the range insulation winding is plotted on the X-Y coordinates where the maximum discharge charge Q m  and the value W relating to the mean discharge energy (for instance, γ) have been graduated in the  two axis directions. According to this graph, the farther the position is separated  from the position of the initial coil group O, the lower the AC dielectric breakdown  voltage (residual BDV) becomes for the residual short time of the winding, but the normal deterioration coil and the abnormal deterioration coil go forward in the  straight line N and A, respectively. Also, when suitable value is put into the expression of VR=100-k 1 (W-W')-k 2  log (Q m /Q m '), and a curve which has made  VRa param eter is drawn on the X-Y coordinates which have been graduated by  log Q m  and γ, it becomes a parallel straight line group. In this way, since not only t he deterioration tendency but also the residual BDV are decided easily, an accident  is prevented.
