Title: Production of semiconductor device
Inventor: MARUYAMA TAKASHI
IPC: H01L21/027
Filed: 1990-08-31
Abstract: PURPOSE:To form resist patterns with high accuracy by selectively working a work with the resist patterns, as a mask, by intermittent development of a resist film after exposing by a developing soln. consisting of an org. solvent. CONSTITUTION:The resist film after exposing is developed by the developing soln. consisting of the org. solvent to form the resist patterns corresponding to the patterns on the work. The development is interrupted where the developing soln. penetrates only in the part of nearly the surface layer of the pattern forming regions. In addition, the resist film is dried between the development and the development of the respective stages. The work is selectively worked with the resist patterns obtd. as a result of the intermittent development as a mask. The deep penetration of the developing soln. is suppressed in this way and the deformation of the resist patterns by the swelling is lessened. The accuracy of the development is thus enhanced.

Patent JP-H0278032-A (JP)
Title: Optical disk device
Inventor: HORI KAZUAKI
IPC: G11B7/09
Filed: 1988-09-14
Abstract: PURPOSE:To improve the S/N of a first stage preamplifier at the time of reading by providing a current lead-in current source through a switching circuit at the output end of a photo detector. CONSTITUTION:A switching circuit 6 and a current source 7 are provided at the output end of a photo detector 3 of an optical signal reproducing part, and the circuit 6 is controlled to be turned-on condition at the time of writing a signal and to be turned- off condition at the time of reading the signal by a switching control circuit 16. At the time of writing when irradiating laser light intensity is large and the output signal current of the photo detector 3 is large, an output current IS is diverted by a current IO by the current source 7, and a current iR supplied to a current-voltage converting resistance RF of a preamplifier 1 is reduced. By increasing the current of the current source 7, a current iO supplied to the resistance RF at the time of writing can be made smaller than a current IO2 supplied at the time of reading. As a result, the value limited to the maximum value of the resistance RF at the time of reading when the current IS is not diverted can be increased up to the unsaturated value after an amplifier 2. Thus, the input conversion noise current due to the thermal noise of the resistance RF can be reduced, and the S/N can be improved.

Title: Method and system for burst profiling
Inventor: WILLIAM B BUSBY
IPC: G06F11/34
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To supply detailed information at low cost by using an operating system(OS) signal and a timer in combination with a dynamic conversion system(DTS), and performing burst profiling. SOLUTION: Before a profiled application is executed, the timer is so set that it is actuated a specific time interval later with a system call. Once the timer is actuated, an OS sends a signal and a profiler acquires this signal and calls a DTS. The DTS decides the address where the execution of the application is stopped from this machine state. When the DTS has a conversion code block corresponding to the address, the DTS executes the block, but when not, the DTS takes the code block starting with the address, converts it, and takes a measurement. The DTS continues to convert, measure, and execute the profiled application until the timer operates again.

Title: Fuel supply control device
Inventor: KOIKE TETSUO
IPC: F02D1/10
Filed: 1982-12-27
Abstract: PURPOSE:To provide possibility of quick acceleration in case of emergency during economical running, by restricting the max. revolving position of a load lever in a mechanical governor, which is installed at the fuel injection pump to control the amount of fuel supply from the pump, through the use of an air cylinder. CONSTITUTION:When a car shall run in the specific economical performance, a control switch 23 open during normal operation is closed and a solenoid valve opened. Then the compressed air in an air tank 22 is supplied to an air cylinder 16 so as to move a piston rod 17 inserted in a full stopper 14 to the left against the force of a spring to cause protrusion of its tip from said full stopper 14. If in this condition a load lever 9 interlocked with the accelerator pedal 11 turns to a great scale, it will contact the piston rod 17 before coming in contact with the full stopper 14. This hindrance of the lever from turning further will cause limitation of leftwise movement to a control rack 12 of the fuel injection pump 2. Thus the amount of fuel supply is restricted.
