Title: Method and device for adjusting shock parameter of hammer-piston for device moved by pressed incompressible fluid
Inventor: JIYAN SHIRUBAN KOMARUMON
IPC: B25D9/26
Filed: 1987-08-07
Abstract: A hydraulic percussion device comprises a housing defining a longitudinal cylinder, a piston longitudinally reciprocal in the cylinder and subdividing same into a front compartment and a rear compartment, and a tool engageable longitudinally with the piston at the front compartment. The compartments are alternately and oppositely hydraulically pressurized to move the piston forward to strike the tool while traveling at an end speed and to move the piston backward away from the tool, the rate of alternation being a frequency parameter and the speed being a force parameter. A controller varies at least one of the parameters by detecting how much the piston rebounds from the tool after striking same and operating the control means in accordance with how much rebound is detected. How much the piston rebounds can be detected by sensing the pressure in one of the compartments immediately after the piston strikes the tool. As rebound increases the pressure in the rear compartment increases relative to a set point or pressure in the front compartment decreases relative to a set point, and vice versa. Rebound can also be detected by sensing the pressure in one of the compartments and at one of the sides of the source and operating the control means in accordance with the differential between these sensed pressures.

Inventor: AOTO KAZUAKI
IPC: G03B31/00
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To realize both of silver salt photography and electronic image photography by using one camera. SOLUTION: When a cassette 22 having the same shape as the conventional film cartridge for silver salt photography is prepared and housed in a cartrtidge chamber and a back cover is closed, the CPU 21 of a camera main body discriminates whether or not data communication can be performed with the cassette 22. In the case the data communication can be performed, the camera waits for the half-depressing of a shutter 7, and when the shutter 7 is half-depressed, photoconductive film 23 is electrified by an electrifier 27, then the electrified spot is moved just under the shutter 7. When a shutter button is totally depressed, the shutter 7 is opened/closed to form an electrostatic latent image on the film 23, and the electrostatic latent image is converted into an electrical signal by an electrification sensor 28 and stored in a memory 29.  Meanwhile, when the film cartridge for the silver salt photography is housed in the cartridge chamber, the conventional silver salt photographic processing is performed. Thus, the silver salt photography and the electrophotography can be performed without changing the camera.

IPC: G11B15/18
Filed: 1981-12-08
Abstract: PURPOSE:To reduce the burden of a controlling circuit and feed a tape with a high precision, by controlling the extent of transportation of the tape and the gain of a driving circuit in accordance with the quantity of rotation of a winding motor. CONSTITUTION:A tachometer 8 inputs one pulse to counters 3 and 11 and a rotation direction detecting circuit 12 for every one rotation of a winding motor 7. The counter 11 is reset when a tape 13 is stopped in the zero position of a stripe 14, but otherwise, the counter 11 counts pulses to store the rotation number of the winding motor 7. A PROM10 outputs a pulse number MDG of the tachometer required for transportation of one-stripe components on a basis of a preliminarily stored program by the output of the counter 11 and feeds back this MDG to a controlling part 2 and inputs the MDG to a multiplier 5 after D/A conversion in a D/A converter 9. The controlling part 2 sets the extent of transportation of the tape 13 to the counter 3 with the MDG from the PROM10 and subjects it to D/A conversion in a D/A converter 4 and multiplies it in the multiplier 5. The output of the multiplier 5 is amplified in an amplifier 6 to control the winding motor 7.

Filed: 1984-09-19
Abstract: PURPOSE:To maintain an old mode without requiring any mode by providing a data processor with plural interruption execution modes and initiating only interruption from a low-level execution mode to a high-level execution mode when interruption occurs. CONSTITUTION:When the execution mode in current operation is changed to another mode, registers 1 and 2 are stored with the current execution mode and old mode. Namely, if a microprogram is interrupted, the mode in operation is moved from the register 1 and held in a register 2 and the mode of interruption generation processing contents is held in the register 1. If there is an interruption factor, an interruption control part 7 compares the expected interruption mode with the current execution mode to allow the interruption when the former is higher in level than the latter or inhibit the interruption when not. When the expected interruption mode is higher in level than the current execution mode, the interruption is initiated, the contents of the register 1 are moved to the register 2, and the expected interruption mode is stored in the register 1.
