Title: Semiconductor circuit, delay adjustment method therefor and layout method therefor
Inventor: ASAO KAZUKI
IPC: H01L21/82
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor circuit capable of preventing the fluctuation of delay time generated by crosstalk, the delay adjustment method and the layout method. SOLUTION: In the case both signals propagated through signal lines S1 and S2 rise, since the output signals of a buffer BU1 and an inverter IV1 become phases opposite to each other, the delay time is increased by the crosstalk. Since the output side driving ability of the buffer BU1 and the driving ability of the inverter IV1 are the same and a wiring length is the same, the increase amounts of the delay time are equal. Since the output signals of the buffer BU2 and the inverter IV2 become the same phases with each other, the delay time is reduced by the crosstalk. Since the output side driving ability of the buffer BU2 and the driving ability of the inverter IV2 are the same and the wiring length is the same, the reduction amounts of the delay time are equal. Thus, the fluctuation amount of the delay time is offset between two wiring sections.

Title: Controller for air conditioner
Inventor: SOGABE MASAHARU
IPC: F24F11/02
Filed: 1987-12-29
Abstract: PURPOSE:To control an air conditioner by a centralized controller even when a remote control switch is disconnected and enable an operating range to be broadened without need for any auxiliary apparatus, by invalidating a signal of abnormality in transfer due to disconnection of the remote control switch, according to a setting signal indicating that the remote control switch is to be disconnected. CONSTITUTION:Signals are transferred between both a remote control switch RCS and a centralized controller 30 and a control unit 16. When an abnormality in transfer occurs, it is detected by a transfer abnormality detecting means 31, and an air conditioner M, for example, is stopped. On the other hand, when a setting signal indicating that the switch RCS is to be disconnected is inputted through a setting button or the like, a disconnection discriminating means 32 outputs a disconnection setting signal. Then, the switch RCS is disconnected, upon which the detecting means 31 detects an abnormality in transfer. The abnormality signal outputted from the detecting means 31 this time is invalidated by an invalidation controlling means 33, and when a control signal for the air conditioner M is inputted from the controller 30, the air conditioner M is controlled from the control signal.

Title: Water-base ink composition
Inventor: SATO NAOKI
IPC: C09D11/023
Filed: 1990-11-28
Abstract: PURPOSE:To obtain the title composition excellent in the resistance to drying at an ink delivery part such as a penpoint by mixing a coloring material, water, and imidazole and/or a compound containing an imidazolyl ring. CONSTITUTION:The title composition is obtained by mixing a coloring material (hitherto known dyes and pigments can be used singly or as a mixture thereof), water, and imidazole and/or a compound containing an imidazolyl ring (e.g. 2-methylimidazole or 2,4-dimethylimidazole). Since the imidazole and/ or compound containing an imidazole ring controls the evaporation of a solvent containing water, the evaporation of the solvent in the ink from a penpoint can be prevented. Also, because this composition does not contain any high- boiling water-soluble organic solvent in a large amont, the viscosity of ink will not increase.
