Title: Laser working method
Inventor: MORI YASUKI
IPC: B23K26/064
Filed: 1982-04-21
Abstract: PURPOSE:To enlarge the region of working by reflecting laser light by a concave mirror and irradiating a work and thereby making the shape of luminous flux in elliptic elongated transversely and longitudinally. CONSTITUTION:Laser light projected to a concave spherical mirror 2 by an angle theta of incidence and reflected has the first focal point f1 and second focal point f2. Near the first focal point f1, the sectional form becomes slitlike form elongated transversely, and near the second focal point f2, it becomes slitlike form elongated longitudinally. Accordingly, when a work 3 is positioned near the focal point f1 or focal point f2, the shape of luminous flux of reflected laser light becomes slitlike form elongated transversely or longitudinally. Since the concave spherical mirror 2 can be cooled effectively by cooling the whole back face of the concave spherical 2 with cooling liquid, high output laser light can be used, and even if sectional area of the luminous flux is wide, working can be performed at high power density.

Title: Liquid fuel combustion apparatus
Inventor: SAITOU TOSHIHIKO
IPC: F23D11/24
Filed: 1979-05-31
Abstract: PURPOSE: To provide a liquid fuel combustion apparatus in which it is made possible to have a rapid start and instantaneous putting-out of combustion by a construction wherein a swirler giving a secondary air swirl flow is mounted in the outside circumference of a burner draft tube, and a flame holder and evaporative plate is mounted on the draft tube flow side.  
     CONSTITUTION: A swirler 10 is mounted in the outside circumference of a draft tube 1 utilizing a circular space 9 given by a burner mounting port 8 of can and the draft tube 1, and further a flame holder and evaporative plate 12 is mounted on the draft tube 1 with several supports. When an ignition plug is operated after purging a combustion chamber inside 13 by a blower 2, and fuel is injected from a nozzle 5 through an electromagnetic pump 3, a flame is formed with being held by a stabilizer 6. When fuel is throttled then, the atomization characteristics of fuel become worse and accordingly mixing of fuel with air is worsened. However, in this construction, a good condition of combustion is maintained by a secondary air swirl flow produced by the swirler 10. Moreover, since a flame is widened in the circumferential direction by the combined flame holder and evaporative plate 12, the mixing characteristic is improved to have less influence by a throttled combustion even if throttled so.

Abstract: PURPOSE:To ensure a smooth operation of change when the currency of the 1st country is paid by the currency of the 2nd country by providing an area where a memory to store an amount, a total amount, etc. paid in the foreign currency converted into the domestic currency. CONSTITUTION:An RAM7 contains a region LECTEND where an amount converted into the domestic currency from the foreign currency is stored, a region IM where a total amount of transactions paid in the domestic currency is stored, a region CHANGE where the change is stored, etc. Then an amount of transaction of domestic currency is stored in a register buffer NBUF by an input of keys through a keyboard 2 and then converted into the foreign currency via a region RATE. When the amount of a region FCTEND exceeds the transaction amount of foreign currency, the amount of the region IM is subtracted from the amount of the region LECTEND. Thus the change is calculated in the domestic currency. In other words, the change can be smoothly calculated by providing regions needed for a memory.

Title: Tester for initial velocity measuring apparatus for shell
Inventor: MIYAZAWA FUMIO
IPC: G01S7/40
Filed: 1982-04-22
Abstract: PURPOSE:To measure the initial velocity of a shell accurately by generating a signal very similar to the received signal of a initial velocity measuring apparatus in the actual shooting. CONSTITUTION:A microwave signal fo emitted from an initial velocity measuring apparatus 1 is sent to a microwave modulator 4 via antenna 2 and a circulator 3. As a Doppler signal fd with a high frequency stability generated from a low frequency oscillator 5 was previously provided to the microwave modulator 4, the microwave signal is outputted to a voltage control type microwave attenuator 6 as a signal fo-fd shifted by the frequency of the Doppler signal. As passing through the voltage control type microwave attenuator 6 to which a signal A was previously provided as control voltage, the microwave signal is turned to a microwave signal B by amplitude modulation. This microwave signal B is returned to the initial velocity measuring apparatus 1 again via the circulator 3 and the antenna 2. Thus, the initial velocity measuring apparatus 1 in normal operation can detect only the Doppler frequency from a microwave signal being complicatedly modulated amplitude accurately thereby enabling the measurement of a simulated velocity.
