Title: Document processor
Inventor: KABETANI NORIAKI
IPC: G06F3/048
Filed: 1990-04-27
Abstract: PURPOSE:To eliminate such a complicated case where an operator corrects the state set after execution of an undesired function by preventing the repetitive execution of the function of a combination key while this key is continuously pushed for command of execution of a function mode. CONSTITUTION:A document processor uses at least one of the specific keys to perform the self-repeat functions as a combination key for command execution of a function mode. Then a no-repeat means is provided to the processor to inhibit the working of a self-repeat means when a key is pushed in a mode where the combination key commands the execution of the function mode. Thus it is possible to evade the execution of the undesired self-repeat actions when the combination key is continuously pushed.

Title: Elevator device for base-isolated building
Inventor: IIBOSHI KATSUHIKO
IPC: B66B7/02
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To provide an elevator device for base isolation building which can normally guide an elevating/lowering body by a guide rail even when the elevating/lowering body is present between a base building body and a base- isolated building during an earthquake. SOLUTION: When an elevating/lowering body 11 is present in an elastic deformation area 8 during an earthquake, the horizontal load is applied to a guide rail 7 on one side by the horizontal displacement of the elevating/ lowering body 11 through a guide piece 12, and the guide rail 7 is deflected. Since a fitting plate 20 is engaged with an engaging body 15 of the guide rail 7 on the other side to which no horizontal load is applied, the displacement of the elevating/lowering body 11 caused by the earthquake is also transmitted to the guide rail 11 on the other side.  Since the displacement of the elevating/ lowering body 11 during an earthquake can be supported by the guide rails 7 on both sides by a constitution which is simple and inexpensively manufactured, the stress exerted in the guide rails 7 is reduced, and the specified strength can be obtained by the guide rails 7 of the standard size.

Title: Suction section of vacuum cleaner

IPC: A47L9/04
Filed: 1993-05-14
Abstract: PURPOSE:To increase the torque of an impeller by forming a passage below the impeller into a spiral passage shape so that the gap between the inner face of the passage and the impeller is decreased in sequence in the rotating direction. CONSTITUTION:A passage below an impeller 2 is formed into a spiral passage 11 shape so that the gap between the passage inner face 12 and the impeller 2 is decreased in sequence in the rotating direction to effectively utilize leakage flow Q2 and increase the torque generation quantity of the impeller 2. The peripheral length AC between an inflow point A from the upper section side of a nozzle outlet and an outer periphery point C of the impeller 2 becomes about 40-50% of the outer peripheral length of the whole impeller 2 for the working length. The outer peripheral length AC becomes almost twice as compared with that of the conventional structure, and the inflow area of the nozzle jet quantity Q0 into the impeller 2 is increased. The leakage flow Q2 in the nozzle jet flow Q0 becomes the nonworking flow in the past. The leakage flow Q2 flows into the impeller 2 in this spiral passage 11, the work quantity of the jet flow Q from a nozzle against the impeller 2 is sharply increased, the turbulence of the flow is reduced, and the noise is reduced.

Title: Semiconductor element measurement circuit
Inventor: ATOBE KAZUO
IPC: G01R31/26
Filed: 1992-02-26
Abstract: PURPOSE:To measure the leakage current of a semiconductor element to be measured irrespective of the value of the applied DC voltage by canceling the leakage current of the measuring instrument itself by adjusting a variable resistor. CONSTITUTION:A voltage which is nearly equal to the voltage to be applied across a semiconductor element to be measured is applied across a measuring terminal T1 without mounting the semiconductor element between measuring terminals T1 and T2. As a result, a leakage current IL1 flows to an equivalent resistor RL1 and resistor RS1 and a voltage VS1 is generated across a node A. On the other hand, another current IL2 flows to a DC resistor RL2 and variable resistor RS2 from a DC power source +HV and a voltage VS2 is generated across the variable resistor RS2 (node B). The resistor RS2 is adjusted so that the voltage VSI across the node A can become equal to the voltage VS2 across the node B (VS1=VS2). Therefore, IL1XRS1=IL2XRS 2 is established and, since the voltage inputted to a differential amplifier AP has no difference, the output VS3 of the amplifier AP becomes VS3=O. When the semiconductor element is mounted between the terminals T1 and T2, an electric current (IL1+ID) flows to the resistor RS1 and only a leakage current ID is outputted from the amplifier AD as the VS3, because the leakage current ID flows to the semiconductor element.

Title: Absorbing type cold water or hot water device
Inventor: MURAYAMA TOMOYUKI
IPC: F25B15/00
Filed: 1990-04-27
Abstract: PURPOSE:To perform a stable operation of an absorbing cold water device by a method wherein a condenser and an absorbing device are connected by a refrigerant liquid blow pipe having an opening or closing valve and opening or closing of an opening or closing valve is controlled by a control panel in response to a temperature of cooling water when a hot water main control for use in controlling a heating calorie of a high temperature generator is carried out in response to a temperature of hot water outlet from a hot water heater. CONSTITUTION:A control panel 45 is operated to open or close the first opening or closing valve 42 for every specified time even in the event that a temperature of a cold water outlet is higher than the second predetermined temperature if the temperature of the cooling water inlet port is low during an operation of a hot water main control when an operation is started, so that absorbing liquid flows to an absorbing device 5 for every predetermined time, the absorbing liquid is diluted, a refrigerant absorbing capability at the absorbing device 5 is gradually decreased and thus it is possible to avoid a rapid reduction of temperature of cold water outlet. Even in the case that a load of cold water is slightly attained, it is possible to avoid a substantial increasing of the cold water outlet temperature caused by dilution. The refrigerant liquid in a condenser 3 is flowed to an absorbing device 5 through the first refrigerant drain pipe 41 under opening or closing of the first opening or closing valve 42 and then icing at the absorbing device 5 in the first refrigerant drain pipe 41 can be avoided.
