Title: Printer
Inventor: SHIMA TOSHIHIRO
IPC: B41J2/35
Filed: 1988-03-18
Abstract: PURPOSE:To determine a constantly stable applicable energy by providing a means to determine whether ink film is a replacement and allowing an applied energy to feed back a measured resistance value for utilization during printing, if the ink film is the same as used previously. CONSTITUTION:The following devices are provided with a sensor 101 for measuring the resistance value of film 101, a non-volatile memory for storage of the resistance value 102, a sensor which detects the presence of ink film 103 and a means for identification of the use of the ink film 104. A means 105 is provided which determines an output from the film resistance value sensor 101, the content of the non-volatile memory 102 and an energy to be applied to a printing head from the means for identification of the use of the ink film 104. If new film is the same as used previously after determination of the film as not yet used, the resistance value of ink film is determined on the basis of a resistance value newly measured and a weighted average value, when printing is performed for the second time and thereafter. If new film is loaded, only the newly measured value is employed as a resistance value of ink film.

Title: Storage element selection device for computer device
Inventor: WATANABE KENICHIRO
IPC: G06F11/22
Filed: 1995-02-28
Abstract: PURPOSE: To obtain the optimum cost price of a computer device without deteriorating an entire function of the computer device by calculating the using states of various memory elements to know the using states of these elements and by securing the designing conditions of memory elements that are optimum to the designing of equipments and to the functions and the cost price constitution of the computer device. CONSTITUTION: When the accesses are given to the memory elements 2 to 5 and 11 to 13 which are connected to the CPU 1 to 1' of a computer device, a totalization result memory 15 records the access execution frequency of those memory elements as well as the access extraction frequency and also records these access states. When the test run of a program ends, an in-circuit emulator device analyzes and calculates each using frequency of elements 2 to 5 and 11 to 13 by means of a memory element access frequency analysis program. Thus the functions of these memory elements to be stored in the initial computer device are evaluated. Then the memory elements having rather low processing speeds and comparatively low prices are used in the cases of lower access frequency among the elements 2 to 5 and 11 to 13.

Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To make an optical pickup compatible with different disks by providing a variable diaphragm to selectively operate depending on wavelengths between laser beam sources and an objective lens to adjust numerial apertures corresponding to beam sources. SOLUTION: A variable diaphragm 30 is constituted of an inside area and an outside area being a variable diaphragm surface, wherein the inside area is straight in the tangential direction but has a curvature in the radial direction of a disk. In the case of reproducing a thin disk DVD 32, a laser beam having a wavelength of 635 nm from a laser source is transmitted without being affected by the influence of the variable diaphragm surface of the diaphragm 30. On the other hand, in the case of reproducing a CD-R 33, a laser beam having a wavelength of 780 nm from a laser beam source is transmitted through the inside area of the diaphragm 30 and the size of a light spot is made to be 1.4 μm by enlarging the spot while making the numerial aperture small in the radial direction of the disk 33 and by reducing the size of the spot while maintaing the numerial aperture large in the tangential direction of the disk 33. Thus, optimum conditions in the reproducing of disks DVD and CD-R is obtained.
