Title: Instrument for measuring power of high output optical pulse
Inventor: HIROSE FUJIO
IPC: G01J1/42
Filed: 1985-06-04
Abstract: PURPOSE:To obtain properly the peak power of a high output optical pulse by calculating the peak power of an incident light beam with the aid of the digital amount of a peak value subjected to peak holding, the transmissivity of a filter and the sensitivity of a photoelectric transfer element. CONSTITUTION:The incident light beam to be measured is attenuated by the filter 11 at the prescribed transmissivity, and the attenuated light beam is condensed by a projecting lens 12. After the condensed light beam is converted into an electrical output to the photoelectric transfer element 13, the peak value of the electrical output is held by a peak holding circuit 16. An A/D converting circuit 17 converts the peak value of the electrical output subjected to the peak holding into a digital amount. Then a microprocessor 18 calculates the peak power of the incident light beam with the aid of said digital amount, the transmissivity of the filter 11 and the sensitivity of the photoelectric transfer element 13.

Title: Manufacture of clad steel material
Inventor: YOSHIDA TOSHIO
IPC: B23K20/04
Filed: 1979-09-20
Abstract: PURPOSE: To obtain a titled steel material with a high working efficiency and high reliability, by forming the faying surface between the steel material and the heterogeneous metal into a truncated cone and then applying the axial direction pressure to both components after fitting together them via the faying surface in order to give the relative rotational motion to them.  
     CONSTITUTION: The faying surfaces A and B are obtained by giving a proper machine finishing to both the inner surface A of the outer tube 1 made of the truncated conical carbon steel and the outer surface B of the truncated conical stainless steel tube 2. The both tubes 1 and 2 are fitted together, and the compression force is applied in the axial direction by the fixed rotary pressing device to apply the set surface pressure on the entire surfaces A and B. Then the relative rotation is given to both tubes 1 and 2 via an appropriate means in order to generate the friction heat through the friction function to secure a hot heating state to both surfaces A and B. The compression force is applied again to both tubes 1 and 2 when the heating temperature becomes a little lower than the material fusing temperature of the tubes 1 and 2 each. Thus an instantaneous press bonding is secured to form a one body. The prescribed hot rolling is applied to this joined metal to obtain a clad steel material made of the double clad tube.

Title: Machine check halt processing system
Inventor: YAMAGUCHI MASAHIKO
IPC: G06F11/00
Filed: 1987-05-19
Abstract: PURPOSE:To realize the error recovery processing via software when the reading is carried out in division by stopping the working of a CPU only when an error is produced again before an error flag is cleared by the error recovery processing after a first error is produced and a vector request signal or vector answer signal is outputted. CONSTITUTION:A machine check enable flag 2 is reset by a vector request signal or a vector answer signal. Then a CPU receives the information of the vector answer signal to complete the prescribed recovery processing and informs an error clear signal to an error flag 1. When an error signal (parity error signal) is informed again before the flag 1 is reset, a machine check halt flag 3 is set and the working of the CPU is stopped. Thus it is possible to read plural memories with a single instruction and to secure the chances for recovery of errors even if the errors are produced continuously.

IPC: G11B7/125
Filed: 1991-05-24
Abstract: PURPOSE:To produce an optical head with a short optical path by diffusing the secondary higher harmonic light beams outputted from a secondary higher harmonic generating means. CONSTITUTION:When a light beam 2 is made incident on a secondary higher harmonic generating means 4, a solid-state laser element 5 is excited for generation of a light beam 8.

The beam 9 is amplified by a resonator consisting of a recess face 7a and an end face 5a and then partly transmitted through a reflector 7 as a light beam 10. Then the beam 9 emitted from the element 6 is turned into the diffused beams through a recess face 6a. At the same time, the beam 10 is also diffused. These diffused beams 10 are condensed by a condenser lens 11 so that a practical beam diameter is obtained with a short optical path.

Abstract: PROBLEM TO BE SOLVED: To display a player character's figure and a visual field range on a monitor, regardless of the existence of a wall or a floor for dividing game space, in the case of indicating the game space as a bird's-eye view. SOLUTION: A game implementation part 31 issues an instruction to a player character image data generation part 32, regarding the display position of a player character. A background image data generation part 37 generates background image data for showing a game space background made of a floor and a wall as a bird's-eye view. A player character position specifying part 34 checks the player character display position for coming behind the wall or the floor in the game space background image. Furthermore, an image composing part 38 composes the image data of the player character with the game space background image.  Also, the player character position specifying part 34, upon judgement that the player character display position comes behind the wall or the floor, changes the wall or the floor hiding the player character, into a translucent status, and corrects the image data so as to show space behind the wall or the floor.

Title: Optical information recording medium, recorder and recording method

IPC: G11B7/24035
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To enable recording and erasure with laser light having a relatively large spot diameter by regulating the ratio of the thickness of a recording layer to the spot diameter of laser light to a specified value or below. SOLUTION: A 1st interference film 2, a recording film 3, a 2nd interference film 4, a reflecting film 5 and an org. protective film 6 are successively formed on a glass substrate 1. The thickness (d) of the recording film 3 is regulated to 3/100 of 1μ spot diameter (ϕ) of laser light, that is, 30nm. When the resultant optical disk 8 is irradiated with laser light, in accordance with the increase of the ratio (d/ϕ) of the thickness (d) to the spot diameter (ϕ), the film 3 becomes less liable to conversion into an amorphous film and the ratio in variation of reflectance before and after the irradiation is reduced. It is necessary to regulate the ratio (d/ϕ) to <=0.1 because >=35% ratio in variation of reflectance necessary for practical use is not attained in the case of >0.1.  In the case of 0.03, the area of the heated part of the film 3 in the plane direction is larger than that in the thickness direction, the heat radiating effect of the film 3 between the films 2, 4 is enhanced in spite of the low heat conductivity of the film 3 and the film 3 can be converted into an amorphous film to attain a high signal level.

Abstract: PURPOSE:To discriminate a microinstruction when it is executed in a desired number of times by using a means which counts the executing frequency of the microinstruction of a specific address within a loop. CONSTITUTION:When debugging is carried out with a microprogram controller, an operator sets an address (m-1) of a microinstruction formed a loop to an external address setter 21. The count value output 52 of a count value setter 51 is set at ''2'' when two rounds of the loop are inspected.

The coincidence is obtained with the output 52 when the numerical value ''2'' is counted, and the comparison result 56 with a comparator 55 is set at H level. This result 56 is held until the result 54 is further counted up.
