Title: Wiring shape and detecting method of wiring route
Inventor: AOKI TAKAAKI
IPC: H01L21/82
Filed: 1992-11-30
Abstract: PURPOSE:To reduce the signal propagation time of the wiring route minimum by a method wherein a wiring which connects a plurality of logic elements is broken down into a plurality of metal segments as one metal segment which connects branch points to each other on the wiring and a segment width is decided by using the driving resistance and the load capacity of one metal segment. CONSTITUTION:A wiring having a plurality of shapes of wiring is broken down into a plurality of metal segments S0 to S8 at every part between branch points on the wiring; a metal segment width which reduces the signal propagation time of the wiring route minimum is decided on the basis of the driving resistance and the load capacity of the respective segments S0 to S8. As a result, the segment width is made gradually fine from the segment S0 on the side of an output terminal P0 toward the segments S4 to S8 on the side of output terminals P1 to P5. Then, the shape of one metal segment is made a taper shape which becomes rectilinearly fine from the side of the output terminal P0 toward the side of the input terminal P1 to P5; in addition, it is quantitized to a taper shape whose width is changed at a plurality of stages. The metal segment having the taper shape is divided into sections having two kinds of widths, and the shape of each section is reshaped in such a way that the signal propagation time of the wiring route is reduced to a minimum on the basis of the driving resistance of the load capacity of each section.

Title: Method and device for charging state control
Inventor: TAMURA HIROSHI
IPC: H02J7/02
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a charging state control method and a charging state control device, by which the charging states of respective cells are made to be uniform securely in a short time. SOLUTION: First, the residual capacities of respective cells are obtained. The cell which has a maximum residual capacity Qmax is selected as an object cell to be discharged. The average value of the residual capacities of all the cells are determined as a target residual capacity Qz which is to be the residual capacity of the object cell after discharge. A target discharge value ΔQ (= Qmax-Qz) is calculated (S210). After a discharge circuit is connected to the object cell (S220), a discharge current Ih which is made to flow through the discharge circuit from the object cell is measured and the integral value Qh of the measured value is calculated. If the integral value Qh reaches the target discharge value ΔQ, the discharge circuit is disconnected from the object cell (S230-S250). As it is judged whether the residual capacity of the target cell reaches the target residual capacity Qz or not without the actual measurement of the open circuit voltage of the cell, the charging states of the cells can be made to be uniform securely in a short time.

Title: Intermediate potential setting circuit and semiconductor integrated circuit
Inventor: TSUJI KEITARO
IPC: H03K19/0175
Filed: 1994-11-30
Abstract: PURPOSE: To obtain a semiconductor integrated circuit capable of performing a high speed memory while reducing through current by using a first conduction type MOS transistor and a second conduction type MOS transistor connected in series between a first reference power source and a second reference power source. CONSTITUTION: An N channel type MOSFET 6 and a P channel MOSFET 7 are connected in series to each other between two reference power sources VCC and a GND and an external load capacitance CL is connected between the connection node ND of these transistors and the GND. Since a time is needed for transiting the output data DOUT of an output terminal directly from an H level to an L level or vice versa, the output is delayed. An intermediate potential setting circuit for suppressing this, in the case where the output data is set to an intermediate potential from the H level or the L level, bringes the potential of the output terminal to the direction opposite to the potential of the output data in a previous cycle. The through current is prevented from flowing in a circuit by setting the intermediate potential while making one of MOSFETs 6, 7 conductive.

Title: Color filter
Inventor: TAKAO HIDEAKI
IPC: G02F1/1335
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To obtain a color filter of excellent quality in which no color mixing state is produced in effective pixels by using an ink jet recording method, by forming a color mixing region between adjacent pixels comprising color patterns of different colors in an effective picture plane. SOLUTION: A photosensitive resin soln. having accepting ability for a coloring agent is applied on a transparent substrate 1 to form an accepting layer for a coloring agent. Then a specified photomask including a color mixing region pattern to be formed between adjacent pixels is used to expose the accepting film layer to harden the film with light. Thereby, a hardened part with light which does not accept a coloring agent and a mixing color region 3 having accepting ability for a coloring agent are formed between adjacent pixels of different colors. Since the color mixing region 3 is formed, an ink overflowing from a pixel during a coloring process can be accepted by the color mixing region 3.  Moreover, by forming the part which does not accept a coloring agent in the adjacent part to the color mixing region 3, mixing of colors between the color mixing region 3 and pixels can be effectively prevented.
