Title: Method of controlling combustion in hot water maker
Inventor: OKADA KAZUHIKO
IPC: F23N1/08
Filed: 1990-05-29
Abstract: PURPOSE:To prevent a variation in the temperature of the delivered hot water when control system is changed over and also prevent instability in the control action by making the calorific value continuous by including the deviation between the control quantity at the time of changing over the control system and the control quantity right after the control system change-over as a constant in the processing by calculation after the change-over. CONSTITUTION:If the previous control action is 51N in unstable area, the control 54 of calorific value is continuously carried out by using the output signals of both a feedforward calculation 20 and first feed-back calculation 21 with reference to the detection values from a water temperature sensor T1 and water quantity sensor Q. If the control action has been shifted 53Y from the unstable area to the stable area, correction term calculation is carried out, and the numerical value of this calculation is stored in a memory M. Next, the numerical value of the correction term that is stored in the memory M is included 55 as a constant by a second feedback calculation 32, and the calorific value control 54 is conducted by the output signal based on the numerical values thus obtained. With this arrangement the discontinuity in the calorific value when the control system is changed over to that with feedback only is eliminated and it is possible to carry out a smooth change-over of the control system with no sudden variation in the calorific value, and a variation in the temperature of the delivered hot water temperature and instability in the control action can be prevented.

Title: Mixture controller for internal-combustion engine
Inventor: TAKIZAWA SATORU
IPC: F02D41/12
Filed: 1982-08-13
Abstract: PURPOSE:To prevent an engine from stalling due to the engagement of a clutch as a throttle valve is entirely closed, by limiting the quantity of the change in the basic supplied quantity of fuel, which is caused depending on the rotational frequency of the engine, during the entire closure of the throttle valve. CONSTITUTION:A controller, which calculates the basic supplied quantity Tp= K.Q/N of fuel on the basis of the rotational frequency N of an engine and the sucked quantity Q of air, judges at a step S2 a value detected by a throttle switch, which is turned on when a throttle valve is completely closed. If the throttle valve is completely closed, the controller judges, at a step S3, whether the basic supplied quantity Tp has decreased by beta or more from the preceding quantity Tp', or judges at a step S4 whether the basic supplied quantity Tp has increased by alpha or more from the preceding quantity. When the decrease is beta or more or the increase is alpha or more, the quantity of the change in the basic supplied quantity Tp is limited to alpha or beta in a step S6 or S5 to prevent the torque of the engine from sharply dropping when a clutch is engaged.

Title: Distance measuring method
Inventor: MORI KENICHI
IPC: G01C3/06
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To make the reliability of calculated distance data verifiable with high accuracy by obtaining the ratio between the valley value of a transition graph and the inclination of the transition graph based on the minimum and least evaluation function value and two evaluation function values adjacent to it, and verifying the reliability of the distance to an object based on the value of the ratio. SOLUTION: In this transition graph, (n) is an integer value and indicates the order of the evaluation function value, y1 indicates the minimum and least value of the evaluation function value, and y1 , y0 , y2 , y3 indicate evaluation function values in a specific range adjacent to the specific range having y1 . The ratio A between the valley value of the transition graph of evaluation function and its inclination is obtained from the equation A=(2y1 +y-y0 )/(y0 -y1 ) based on y1 and y0 and y2 adjacent to y1 . The valley value is the intersection between a straight line connecting a point (n-1, y0 ) and a point (n, y1 ) and a straight line having the inclination symmetrical with this straight line against the y-axis and passing through a point (n+1, y2 ), for example.  When the value of the ratio A is 1 or above, the distance data is judged to be obtained via defocusing and is excluded.

Filed: 1992-04-30
Abstract: PURPOSE:To perform printing without conducting an error processing even if a pattern data amount exceeds a buffer storage capacity by a method wherein when a block data length is judged to be larger than a buffer data length, dot pattern data is printed by the number of blocks which can be stored in an image buffer. CONSTITUTION:In a tape printer, a text stored in a text memory 41 is divided into first - fourth blocks through a block key. Block marks M1-M4 are inputted for every delimitation between the block data. Furthermore, the respective block data are accumulated through a text pointer 42 at every detection of the marks M1-M4. The accumulated block data length is compared with an image buffer data length set through a key and stored in a buffer data length memory 43, whereby the data is printed through a thermal head by the number of blocks which can be stored in the buffer. Therefore, even if a dot pattern data amount exceeds the storage capacity of the image buffer, printing can be performed without conducting an error processing.

Abstract: PURPOSE:To make black lines on a luminous surface hardly visible by means of an asymmetric electron lens formed between strip-shape grid element assemblies and a damp wire and improve display quality by using the damp wire which is made of a W (tungsten) wire coated with a secondary emission material. CONSTITUTION:A damp wire 14 which is made up of W (tungsten) wire 12 coated with a secondary emission material 13 consisting of a semiconductor such as Mg0 and Cs2O is stretched on the fluorescent screen side of a plurality of grid element assemblies 11 being stretch-arranged along one direction, in the direction intersecting the stretched direction of the grid element assemblies. Using the wire 14, electrons to collide with a fluorescent material are selected from an electron beam 15 emitted from an electron gun to make the fluorescent screen luminous by numerous strip-shape grid element assemblies 11 as a color selecting electrode and pass through between the element assemblies 11. Since a part of the electron beam 15 collides with the wire 14, the electron beam 15 in an area 17 of the fluorescent screen 16 side backward of the wire 14 is interrupted. But since the wire 14 is being coated with the material 13, an asymmetric electron lens 18 is formed between the element assemblies 11 and the damp wire, thereby the electrons reach the fluorescent screen of the area 17 interrupted by the wire 14.

Title: Light beam scanner
Inventor: ABE MICHIHARU
IPC: G02B26/10
Filed: 1978-11-15
Abstract: PURPOSE: To provide such a device which enhances the utilization efficiency of light and permits easy recording by imaging a spot light source on the surface to be scanned by Fresnel lenses and providing a means of moving the lenses in the scanning direction.  
     CONSTITUTION: Parallel beams 1 are condensed by a condenser lens 2 to from a  spot light source S. An imaging lens 3 is placed in such a position that the image is formed at the point P(o) at a magnification m but when the imaging lens 3 is moved by x in the arrow 4 direction, the imaging point of the spot light source S moves to the point P(x) apart by mx from the optical axis O-O of the imaging lens 3. Since the optical axis O-O has moved by x as well, the imaging point of the spot light source S moves to the point P(x) apart by (1+m)x from the point P(o) where it had initially existed. Namely, the imaging point of the fixed spot light source S scans on the imaging plane by moving the imaging lens 3. By using this principle with Fresnel lenses L 1 WL 8 , a rotary disc 6 is rotated at a high speed and  the scanning locus Q-Q of arc is obtained on the surface to be scanned 5.

Title: Laser welding
Inventor: USHIMI KENJI
IPC: B23K26/21
Filed: 1977-11-25
Abstract: PURPOSE:A united lens consisting of a plurality of lens with each optical axis offset is used to concentrate divided laser beams. Before concentration, laser beams are intersected each other to project onto inner surface of cylinder member thereby effecting a multiplace, simultaneous inner surface welding of high quality and high efficiency. CONSTITUTION:A laser beam 4 emitted from an oscillator is projected through a center portion of a joint lens 6 which is a joined assembly of eight fan-shaped lens sections of same size and same quality. The laser beam 4 is devided into 8 beams by lens sections 7 and each devided laser beam 4a is concentrated on each optical axis 8 of respective lenses. Each laser beam 4a intersects in front of each concentration, because each optical axis 8 exists outside of lens section. As laser 14a intersects, it is less likely prevented by side wall of a cylinder 8. This provides a highly  densitied energy concentrated onto welding zone, whereby high energy laser 4 enables a simultaneous multiple-zone welding of cylinder inner face.
