Title: Laser marking material and marking method
Inventor: KIYONARI TOSHIYUKI
IPC: B41M5/26
Filed: 1988-03-03
Abstract: PURPOSE:To perform a sharp marking, by a marking method wherein a laser light is irradiated on the surface of an article made of a material consisting of a boric acid-containing inorganic substance. CONSTITUTION:As a marking material, all boric acid-containing inorganic substances can be used, but a lithium borate anhydride or a calcium borate anhydride is preferably used for especially obtaining superior transparency and color forming properties. The boric acid-containing inorganic substance is incorporated in the amount of 5-80wt.%, preferably 15-60wt.%. If the content is less than 5wt.%, a sharp contrast cannot be obtained. If more than 80wt.%, the physical properties are remarkably deteriorated. A sharp marking can be obtained by irradiating a laser light having a suitable strength on the surface of a resin molded material or resin coated material consisting of the boric acid-containing inorganic substance through a mask.

Title: Information equipment, residual amount informing method and recording medium
Inventor: SUNAKAWA SHINICHI
IPC: H02J7/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide information equipment allowing enhancement of recognizability of a residual amount display without reducing user's workability. SOLUTION: In this portable information terminal, a residual amount detection part detects a residual amount of a battery (S100). It is decided whether the detected residual amount of the battery is below a threshold value or not (S101). In the case that the residual amount is below the threshold value, the residual amount is decided to be an alarm level, so that an icon is set to a magnification size (S102). In the case that the residual amount is not below the threshold value, the residual amount is decided to be sufficient, so that the icon is set to a standard size (S104). Then, the icon is displayed on a screen in a layout corresponding to the size set at S102 or S104 (S103). In the screen display of the layout in the case that the residual amount becomes less than the prescribed value, the battery icon is displayed in four times size of the standard size.

Title: Laser beam machine and its machining method
Inventor: NAGABORI MASAYUKI
IPC: B23K26/21
Filed: 1988-03-04
Abstract: PURPOSE:To uniformize a laser beam radiation amt. and to prevent the nonuniformity in machining by equipping the light shielding means shielding one part of the laser beam in a return scanning area. CONSTITUTION:A laser beam LB is scanned on a welding face S by return after placing the body 6 to be welded on a stage 5 and focusing a condensing lens 4 on the welding face S. While the laser beam LB scans a straight line scanning area it is not shielded by a light shielding mask 12 but in the return scanning area the laser beam LB is partially shielded by the light shielding effect of the mask 12. The shielded amt. becomes larger as approaching to a return point and max. at the return point. The laser beam radiation amt. thus becomes uniform over the whole scanning area and the welding nonuniformity can be prevented.

Title: Semiconductor logic element
IPC: H03K19/086
Filed: 1992-03-10
Abstract: PURPOSE:To reduce the switching time by controlling a drive transistor(TR) corresponding to a collector output level of a current changeover switch so as to increase an emitter follower current at trailing. CONSTITUTION:An emitter of an emitter follower TR QEF is connected to an output VOUT and a collector of a drive TR QCE. A gate of an enhancement P-channel MOS TR T1 is connected to one collector output OC of a current changeover switch. In the transition state of an input VIN falling down from a high level to a low level, after the TR T1 is turned off, a potential at a node BCE is gradually decreased to turn off the TR QCE. When a high resistance is selected for a resistor RB, a potential decrease at the node BCE slows down. Thus, while an emitter follower output is sufficiently fallen down, the charge of a load capacitor connecting to the output VOUT is discharged by the TR QCE.

Title: Picture defect compensating device
Inventor: SUGIURA HIROAKI
IPC: H04N5/217
Filed: 1985-03-13
Abstract: PURPOSE:To attain high accuracy image defect compensation by substituting defect pixel signals for a means value of two adjacent pixel signals disposed towards the larger picture correlation. CONSTITUTION:In case of a larger picture correlation in the horizontal direction, as a defect pixel signal P (i, j) is applied from a one pixel delay circuit 15 to a substitution circuit 15, a 'H' level signal is produced from a defect compensation signal generator 29 in timing with it sand supplied to a control element 30a of the circuit 30. When the signal supplied to the terminal 30a is 'H' level, the circuit 30 selects and outputs the signal from a selection circuit 28. As a result, the signal P (i, j) is substituted by a signal represented by an mean signal close to the normal signal level to compensate for the picture defect. When there exists a larger picture correlation in the vertical direction, the circuit 30 outputs, when the signal (i, j) is a defect picture signal, a mean value of the signal level of two adjacent normal pixel signals adjacent to the defect pixel signal.

Abstract: PURPOSE:To sufficiently secure a chain time by providing a buffer for temporarily storing the address of a subchannel and the number of bytes between an I/O and a main storage and controlling the timing of a queue and a subchannel request signal. CONSTITUTION:The data transfer working area (buffer) 4 for temporarily storing the data address of a subchannel at the time of directly transferring a data unit with a prescribed length by data chain between the main storage 3 and the I/O is provided.

When both the addresses coincide with each other, transfer between the buffer 4 and the main storage 3 or the buffer 4 and the main storage 3 is waited, and at the time of discrepancy of the addresses, transfer is started in accordance with the sizes of the numbers N0, N1 of counted bytes. Consequently, the queuing time can be set up in accordance with the input of a transfer direction and the chain time can be sufficiently secured.
