Patent JP-H11243338-A (JP)
Title: Current cell type da converter
Inventor: YOSHIDA SHINYA
IPC: H03M1/74
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in an operation waiting state and also to immediately return to a normal operation state from the operation waiting state by providing a 3rd transistor that conducts or interrupts a current between a 1st transistor that becomes a constant current source to each current cell and a voltage source. SOLUTION: A PMOS 18 conducts or interrupts a current between a PMOS 20 that becomes a constant current source and power supply. A sleeve signal is on a low level and the PMOS 18 is turned on at the time of a normal operation. Compared with it, the sleeve signal is on a high level, the PMOS 18 is turned off and consequently, a current no longer flows into the PMOS 20, either at the time of waiting for an operation. In this state, an output of an amplifier 28 of a gate potential setting part 14 is completely the same potential as a normal operation state and power consumption in an operation waiting state can be reduced remarkably because no current flows into the PMOS 20 that occupies most of current consumption even though a DC current slightly flows into a ground from the power supply through a resistance Rset.

Title: Shoe plate for bulldozer, etc.
Inventor: MATSUOKA KATSUYOSHI
IPC: E02F3/815
Filed: 1980-05-02
Abstract: PURPOSE: To obtain shoe plate for both dry and wet lands by forming the earth- contacting face of the shoe plate body of a bulldozer into a curved shape.  
     CONSTITUTION: A shoe plate 1 is formed into a curved shape. Thus, the earth- contacting area of the shoe plate is made smaller on the hard ground, and its mobile power is therefore made better. Also, even on soft ground where usual type bulldozer for dry land is difficult to work, the earth-contacting area enough to support the total weight load of the bulldozer can be obtained. Furthermore, the earth- contacting area of the shoe plate on soft and wet lands becomes maximum, thus permitting the bulldozer with the shoe plate to exhibit the same performance as that of the bulldozer for wet land.

Title: Document editing device
Inventor: SASAKI RYOICHI
IPC: G06F17/21
Filed: 1988-03-11
Abstract: PURPOSE:To facilitate the input of dead characters by inhibiting a processing mode in case the immediately preceding input data is equal to the dead characters at input of the division data for character strings. CONSTITUTION:When the data supplied via an input means M1 is equal to the division data which divides the character strings, a process means M2 performs a prescribed process. While the input data is stored in a dead character memory means M3 as long as said data is equal to the dead characters that cause no replacement of the output position after the output of characters. Furthermore it is decided whether the immediately preceding data is equal to the dead characters or not based on the contents of the means M3. If so, the process carried out by the means M2 is inhibited by an inhibiting means M4. As a result, the spaces supplied right after the input of the dead character data are processed as the dead characters.
