Title: Printing head
Inventor: YONEYAMA YOSHIYUKI
IPC: B41J2/275
Filed: 1988-10-07
Abstract: PURPOSE:To perform high speed printing by shortening the vibration time of an armature after printing operation by arranging buffer materials in the vicinity of the shaking center of the armatures, which are respectively supported by a head main body in a shakable manner, on the surface side of printing paper. CONSTITUTION:When a core 15 is temporarily excited by selectively supplying a current to a coil 17, an armature 30 is shaken up to a printing position around a torsion bar 42. The moment a type is struck, the force in the direction going to a rear yoke 13 acts on the leading end part of the armature 30 as the reaction force of said striking. By said reaction force, rotationary power almost centering around the center G of gravity acts on the armature 30 and, contrarily, the force going toward a platen 31 acts on the part above the center G of gravity. Therefore, the strain due to the force going toward the platen 31 is generated in the part of the torsion bar 42 of a leaf spring 26 and, as a result, high order vibration is generated but, since the buffer materials 27 are arranged at the position where said vibration is generated, the energy due to said force is absorbed and the strain of the torsion bar 42 is suppressed as low as possible and, as a result, the time required before the armature 30 returns to a stationary position becomes short.

Abstract: PURPOSE:To achieve an excellent finish of cooking by heating in next time by calculating the time of cooking in next time with a correction to a basic heating time by a correction value which is calculated by addition means, deduction means, and correction means according to the heating time and heat source of this time and the time of non-heating up to the next heating. CONSTITUTION:When an electric power source is turned on a memory 12 and CPU 11 are reset. Next, a display section 4 is controlled to display respectively the residual time during heating and present time during non-heating. And, by signals from temperature measurement means 10 the ambient temperature is measured, and the value of a variable is determined according to the measured temperature. By the way the speed of temperature fall in a heating chamber during non-heating is influenced by the ambient temperature, but since the temperature measurement means 10 is provided for measuring the ambient temperature and the content of the deduction means is changed by changing the value of the variable according to the results of the measurement it is possible to obtain a constant finish regardless of the ambient temperature.

Abstract: PURPOSE:To enhance the control accuracy of a fluid pressure control device for a differential motion limiting clutch or the like in a vehicle drive system, by compensating a control signal for an actuator such that a detected control fluid pressure in the clutch is made to approach a desired fluid pressure and then by feeding-back the thus compensated signal. CONSTITUTION:When signals from an input sensor 6 for detecting an accelerator opening degree, a vehicle speed and a control pressure are delivered to a control means 7, the control means 7 delivers a fluid pressure control signal (c) to a fluid pressure control means 9. Meanwhile, a signal (p) from a sensor 8 for detecting a fluid pressure fed by an actuator 5 is delivered to the control means 9. Further, the control means 9 delivers a feed-back signal (c') to the actuator 5 so that the fluid pressure detection signal (p) is made to approach a desired fluid pressure in accordance with the control signal (c). The actuator 5 controls the fluid pressure for a clutch means 3 in accordance with the feed-back signal and delivers the same. With this arrangement it is possible to enhance the control accuracy of the clutch fluid pressure control device.

Abstract: PURPOSE:To obtain the title lead frame causing no cracking at all even in reflow time by a method wherein flame coating films in specific thickness is formed on the front surface and the rear surface of a die pad to enhance the bond properties onto a mold resin. CONSTITUTION:Flame coating films 4a, 4b comprising aluminum (Al) or aluminum oxide (Al2O3) or silicon oxide (SiO2) in thickness of 1-3mum are formed on the front surface and the rear surface of a die pad 3 encircled by lead 2. Within the flame coating films 4a, 4b, molten particles jetted from a nozzle adhere to the surface of a die pad to be coagulated thereon furthermore, a coated layer is formed by the molten particles coated on the coagulated particles. At this time, cavities are formed between the fixed particles to make the whole film surface porous. Accordingly, the surface area is increased to enhance the bond properties onto the mold resin. Furthermore, due to the formation of the flame coating films 4a, 4b comprising the homogeneous material, the die pad is not to be deformed thereby enabling a stable resin mold 7 to be obtained.

Title: Method and device for converting image and record medium recording procedure for image conversion
Inventor: SAKAIDA HIDEYUKI
IPC: H04N1/60
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To provide more accelerated image converting processing with no error by improving a direct mapping method. SOLUTION: The apex coordinate of each block in a color space 1 divided into plural blocks with the block of a prescribed size as a unit is previously transformed by a transforming means 3 and a provided transform value is recorded in a transform table 4. Besides, when the block of a size different from the block of the prescribed size exists among the divided blocks, the transform value of each apex coordinate at the time of virtually replacing such a block with the block equal with the prescribed size is generated by a generating means 5 and recorded in a virtual transform value table 6. Further, the number of apexes to be used for interpolating operation for each position in the block, the apex itself and weight coefficient of that apex are found and previously recorded in a coefficient table 7. When finding the transform value of pixel value of a color image 9, an interpolating operation means 8 respectively reads the transform value of the apex coordinate from the transform value table 4 or virtual transform value table 6 and the information of the apex required for interpolation from the coefficient table 7 and performs image conversion by executing simple product sum calculation while using these data.
