Patent number: 6648530Abstract: As it is often difficult for users of a keyboard to adequately identify and select the correct keys in a keyboard where the light is inadequate, it is desirable to provide a keyboard capable that allows a user to better see keys of the keyboard even in environments where there is not sufficient light to see the keys (e.g., in an airplane). A keyboard of the present invention comprises a substrate, a membrane, an elastic member, a cover sheet, a keytop, and light-emitting means for emitting light from the bottom of the substrate to the keytop. The keytop is illuminated and a legend on a key surface can be seen, so that the chance of incorrect key stroke is reduced.Type: GrantFiled: February 28, 2002Date of Patent: November 18, 2003Assignee: International Business Machines CorporationInventors: Nobuyuki Kamei, Tohru Nakanishi, Akihiko Kitanaka

Patent number: 6283380Abstract: An air conditioning system and an air conditioning method are disclosed for quickly and effectively controlling the temperature in a room requiring cooling and keeping the room at a uniform temperature. The present invention estimates a temperature distribution in a room through a simulation and controls airflow rates and airflow directions of a plurality of fans on the basis of the simulation result. Temperature sensors are arranged at predetermined positions in a room such as a computer room. A simulation is performed on the basis of temperatures detected by the temperature sensor Sn and the current airflow rates and airflow directions of a plurality of fans to obtain a temperature distribution in the room. It is determined whether obtained temperatures are in a predetermined temperature range. As the result of such determination, at least one of airflow rate and airflow direction of a fan which covers a position being at a temperature out of the predetermined temperature range is controlled.Type: GrantFiled: March 20, 2000Date of Patent: September 4, 2001Assignee: International Business Machines CorporationInventors: Tohru Nakanishi, Hirohito Terada, Motokazu Kawase

Patent number: 5815919Abstract: To prevent solder bridges that will easily occur in soldering an element whose leads are narrow in spacing. In a solder resist, there is provided an excess-solder absorbing region in which solder resist is not provided, between an end of a solder pad and the distal end of a lead. When a great deal of solder paste is applied to the solder pad for soldering the lead, an excess of solder melted due to the heat of a heater, flows along the lead and into the excess-solder absorbing region toward the distal end of the lead. Since the excess of solder does not flow across the solder resist provided between the leads, no solder bridge is formed.Type: GrantFiled: August 3, 1995Date of Patent: October 6, 1998Assignee: International Business Machines CorporationInventors: Tohru Nakanishi, Hideo Ohkuma
