Title: Hole excavator by retractable bit
Inventor: TAKEUCHI HISAO
IPC: E21B4/14
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To enhance performance by arranging a double tube drill rod to which a casing, a retractable bit and a cleaning swivel are connected, and sending fluid in the inverse circulation. SOLUTION: A retractable bit 20 is connected to an integrated double tube drill rod 41 through a head-sub 30, and an expansible/contractible bit part 21 is projected from a casing 42 so that a main body part 22 is inserted into the casing 42. Step differences 22b and 42a are respectively arranged on/contacted with the outside of the main body 22 and the inside of the casing 42 to transmit stroke force and supply advance force to the casing 42. Fluid is sent to a tube 41a by the inverse circulation from a clearance between the inner tube 41a and an outer tube 41b by connecting the upper end of the rod 41 to a cleaning swivel 43. Therefore, strength of the casing can be reduced since a casing having no bit can be accompanied together, and efficiency can be improved since the casing is not mounted on/demounted from the cleaning swivel, and the drill rod can be easily mounted/demounted, and weight can be reduced since a tube diameter is small, and execution work can be performed by a small excavator.

Title: Speculative execution instruction number count device
Inventor: SAWAMURA AKIHIRO
IPC: G06F9/38
Filed: 1997-12-29
Abstract: PROBLEM TO BE SOLVED: To shorten an analysis time for program optimization or hardware performance improvement by adapting the number of speculative execution instruction. SOLUTION: A speculation level counter 4 counts a speculation level α when a branching instruction is registered in a reorder buffer 3 and a speculative level holding means 5 holds the speculation level α. An execution instruction selection means 6 selects an instruction for starting execution out of the reorder buffer 3 and, at the same time, selects the speculation level αcorresponding to this instruction out of the speculation level holding means 5 and outputs it as an execution instruction speculation level γ. When it is detected by a branch instruction execution detection decoder 7 that this instruction is the branching instruction, a speculation release level counter 8 counts a speculation release level β.  A speculative execution detection means 9 compares the speculation level α, the speculation release level β and the execution instruction speculation level γ, detects speculative execution and a speculative execution instruction number counter 10 counts this.

Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a digital still camera suitable for picking up the image of the object of an achromatic color and suitable for picking up the image of a moving object by providing an exposure setting means for setting an exposure more than an appropriate exposure to object field luminance when an achromatic color image photographing mode is set. SOLUTION: In the case of picking up the image of a whiteboard BC by using this digital still camera to which an achromatic color mode is set, an MPU sets the exposure more than the one at the time of normal image pickup by opening a diaphragm or the like for instance. Thus, the white area of the whiteboard WB is turned to a state where the pixels of a CCD are saturated or slightly before saturated and thus, a contrast difference between the white areas is eliminated and clearer images with less noise are obtained. Further, when the MPU increases a dark clip processing amount, for characters BC entered to the whiteboard WB, the contrast difference is eliminated by a dark clip processing and the clearer images with less noise are obtained.

Title: Card driving device
Inventor: KITAHARA TOSHIHIRO
IPC: B65H5/06
Filed: 1990-12-07
Abstract: PURPOSE:To expand the moving range of the optical head moving in the crass direction of the optical card without making the card driving device large-size. CONSTITUTION:Balls for carrier 19a, 19b are arranged in the crass direction of an optical card 1b and at the interval nearly equal to the width of the crass direction of the optical card 1b. An optical head 28 moves between the ball for carrier 19a and the ball for carrier 19b and reads the information on the recording surface mounted on the lower surface of the optical card 1b. The mechanism to store the balls for carrier 19a, 19b becomes small size because it is unnecessary to mount the rotary shaft controlling of the rotary direction since the balls for carrier 19a, 19b are spheres. Therefore, the area capable of moving the optical head 28 can be expanded.
