Filed: 1993-04-16
Abstract: PURPOSE:To provide a thermally cutting machine for finely thermally cutting the heat molten substance such as foamed styrol. CONSTITUTION:A hopper 2 for feeding the heat molten substance 26 is installed in the upper part, and a plurality of electric heating wires 18 and 19 for thermally cutting the heat molten substance 26 are laid in the upper and lower stages, keeping a prescribed interval, and in the longitudinal, lateral, and aslant directions in each stage, and an accommodation part for recovering the thermally molten substance 27 which is thermally cut is installed under the electric heating wire 19 in the lower stage. Accordingly, the thermally molten substance 26 fed into the hopper 2 falls by its dead weight, and is finely thermally cut in the longitudinal and lateral directions during passing through both the electric heating wires 18 and 19. The finely divided cut pieces 27 do not become bulky, when piled, and the piling place can be reduced, and the efficiency in transport and storage can be improved drastically, and the succeeding handling is facilitated.

Title: Position detector and position detecting body for use therein
Inventor: MURAKAMI EIICHI
IPC: H01L21/027
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To attain an alignment of a small offset of each step which is insensible to an adjusting state of a detection optical system by a method wherein an undercut of a mark formed on a body satisfies the specific relation equation between a wavelength of beams from an irradiation system and a refractive index of a medium that the mark exists. SOLUTION: When a wavelength of detecting beams is represented by λand a refractive index of a medium that a mark exists by N, an undercut d of the mark is set to satisfy 0.8×(λ/4).<N×d<1.2×(λ/4)m. Herein, m=1, 2,.... For example, if the refractive index N of resist 60 under a state that resist is applied onto the mark is set to be 1.4 and the detection wavelength λis set to be a wavelength of HeNe laser, the undercut d is 113nm. Thereby, a position detection with high precision which is not influenced by an adjustment state of a scope is possible. An alignment mark 31 is structured in such undercut, whereby an offset between steps is reduced so that an attempt can be made to enhance position detection precision.

Abstract: PURPOSE:To improve the use efficiency of the address space of a RAM by using the area from the start address of an initial program to the address set by the initial program as the address space of a ROM and using the following area as the address space of the RAM though this following area overlaps the address space of the ROM. CONSTITUTION:An initial operation program is sent from a ROM 2 to a CPU 1 and is executed by the CPU 1, and the address of the ROM 2 up to which programs required after execution of the initial program are stored is held in a latch 11 during operation of the initial program. When the next program is executed, the address value from the CPU 1 is sent to the ROM 2, a RAM 3, and a comparing circuit 9. The comparing circuit 9 compares the output from the latch 11 with that from the CPU 1; and if the address value outputted from the CPU 1 is equal or larger, the output terminal of the ROM 2 is made high-impedance to make input/output to the RAM 3 possible. If said address value is smaller than the value from the latch 11, input/output terminals of the RAM 3 are made high-impedance, and the ROM 2 outputs data in the address, which is outputted from the CPU 1, to a data bus 5.

Title: Printer, and method and apparatus for driving head thereof
Inventor: SEKO YOSHIKAZU
IPC: B41J2/045
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To enable high speed printing in a desired printing region. SOLUTION: A busy signal is generated during one emitting cycle emitting ink by driving a head corresponding to an emitting demand and the generation period of the busy signal is set so that the emission of a next emitting cycle is delayed up to a point of time when the busy signal falls even if there is a next emitting demand and the interference of before and behind emitting cycles is prevented. When there is no next emitting demand during the generation period of the busy signal, emission is started at a point of time when the next emitting demand is generated. Since an 'idling period' is not required within one emitting cycle, high speed printing becomes possible.

Filed: 1995-04-17
Abstract: PURPOSE: To prevent a pay program from being viewed free and to simultaneously prevent the generation of an irrational situation that the toll program is displayed in a slave picture and its toll is charged for a user, by converting the image of the slave picture to any abnormal image corresponding to acquired pay information. CONSTITUTION: It is discriminated from the acquired description of PPV- descriptor whether that program is pay one or not. When the program is not a pay one, a CPU 29 displays that program in a normal state. When that program is a pay program, on the other hand, it is discriminated whether that user (an IRD 2) is a permitted viewer or not. The ID of the user (user ID) of this IRD 2 and a flag for permitting the viewing of the pay program are recorded in a CAM 33 in principle. When the user having this user ID does not pay the toll even after the viewing of the toll program, however, a broadcasting station inhibits the user having this user ID from viewing.

Title: Operation of hydraulic turbine
Inventor: SAKAGUCHI KATSUMI
IPC: F03B15/18
Filed: 1981-07-24
Abstract: PURPOSE:To prevent an accident to occur by the resonance of hydraulic turbine runners by providing a moderate decrease ratio of revolving speed of the hydraulic turbine with respect to opening of a guide vane when the hydraulic turbine is driven up to a speed which stands below a rated speed of the hydraulic turbine and exceeds a critical limit of resonance. CONSTITUTION:When a hydraulic turbine is driven in a parallel operation mode of a system, a speed governor of the turbine detects frequencies of the system. Opening of a guide vane is regulated on the basis of variation of the frequencies and a prefixed speed decreasing ratio so as to control the output power of the hydraulic turbine. Characteristic lines of normally decreased revolving speeds are cut off at points P1-P3 which stand below a rated speed Vd and exceed the  critical limit (Vc) of resonance to reduce respective speed decreasing ratio in  the range of revolving speeds at P1-P3, hence preventing the revolving speeds  of a main engine from being induced into the critical zone Vc of resonance during parallel operation of systems. Since an accident caused by the resonance of runners of the hydraulic turbine is prevented, and safe and reliable operation  may be ensured.
