Patent GB-2345605-A (GB)
Title: Producing hybrid halftone images
Inventor: TRASK JEFFREY L
IPC: G03F5/22
Filed: 1999-10-19
Abstract: A system (100) provides a halftone image having reduced moir patterns by applying a screen function of the type having a first function exhibiting symmetry about a point and a second function exhibiting symmetry about a line. In a progression of tone levels, such a screen function creates first dots (600), then lines (800), then dots (1000). For example, a screen function may include the sum of a first function of the type <F>(1-cos(pi*(x+y))*cos(pi*(y-x)))</F> and a second function being a piecewise linear function of x, where  x,y  is a coordinate location in a unit cell (506) mapped to a halftone cell (504) mapped to the image pixel grid (510). In other embodiments, a unit cell (1104) is defined on the grid by a vector. The vector has a component along an axis of the grid. The component has a noninteger length. Unit cells of the type so defined implement rational tangent angles not possible with conventional halftone cells.

Title: Process for forming of rust-proof pot with decorated bottom plate
Inventor: CARTOSSI FERDINANDO
IPC: A47J36/02
Filed: 1994-02-10
Abstract: The method enables a stainless steel cooking utensil to be formed with a decorated base, the base being of the type comprising three layers (12,14,18), of which one (12) is an intermediate layer of a good heat conducting metal and the other two layers are of stainless steel. Compared with traditional methods for forming normal utensils of the aforesaid type, there is a further step consisting of positioning on the outer stainless steel layer at least one sheet portion of a metal having a melting point not less than that of the metal forming the intermediate layer. An aluminium foil (22) is interposed between the sheet portion (18) and the outer stainless steel layer (14) if the metal of the sheet portion (18) does not enable a direct permanent connection to be achieved between the sheet portion and the outer layer. A decoration can also be obtained on the inside of the utensil base in a similar manner. <IMAGE>

Abstract: PURPOSE:To raise the quality of recording by forming a trapezoidal drive voltage wave by a method in which a current buffer is connected to the transistor of a circuit to pulse-drive a piezo-electric element and the output end of the buffer and the base of the transistor are connected with a return condenser. CONSTITUTION:An input line B is connected to a transistor Q11 through an inverter T11, a piezo-electric element P11 is connected to the output end of transistors Q12 and Q13 constituting a current buffer, and a return condenser C11 is provided to make up the drive circuit of the element P11. When recording is not made, input signal B becomes ''L'', the output of the inverter T11 becomes open, the transistor Q11 becomes ON, and drive voltage Vp becomes almost 0. When the signal B becomes ''H'', the output of T11 becomes almost 0, Q11 becomes OFF, and the drive voltage rises linearly to +VH. After the lapse of a given period of time, when the signal B becomes ''L'', the voltage goes down linearly. The dispersion of the drive wave form can thus be eliminated and the generation of satellite can be prevented.

Title: Gas shut-off device
Inventor: NAKAHIRA MASANOSUKE
IPC: F16K13/10
Filed: 1979-02-02
Abstract: PURPOSE: To surely shut off gas flow with a simple construction by setting the bottom of a cylindrical damper loose to a shut-off port of a gas passage and sealing the cylinder's opening with water.  
     CONSTITUTION: Normally a damper 4 rises upright to let gas G flow from a passage 1 to another passage 2. When a damper-close signal is issued, a motor 7 is activated to turn a rotary shaft 5 through a reduction gear 9. A hook gets loose to make the damper 4 lie flat over a port 1a for shutting off the gas flow. At this moment an actuator 18 actuates a switch 19 to interrupt the motor 7, and a solenoid valve 24 is opened to let water in a water tank 20 flow in a casing 3 for sealing the damper opening with water. Even if gas leaks out through a clearance between the damper bottom and the port's end face, the seal water kept under high pressure prevents gas from leaking out.
