Inventor: TADA TAKEHIKO
IPC: A63C5/044
Filed: 1994-11-08
Abstract: PURPOSE: To reduce frictional resistance of a ski to be used mostly in an artificial skiing area and to make it easy for a skier to turn his skis etc., so that easy and smooth skiing can be enjoyed by making several brush-like projections on the sliding face of the ski. CONSTITUTION: Several brush-like projections 3 are formed on the sliding face of a ski 1 used mostly in an artificial skiing area. By supporting the ski 1 with the projections 3, the frictional resistance between the ski 1 and the skiing ground surface 10 can be educed, so that the ski 1 can more smoothly be slid on the ground. And if a skier moves his weight, the angle and ratio of bending of each projection 3 on the tip, tail, right, and left of the ski are adjusted to change the frictional resistance, so that the skier can easily change the direction of the skis by turning his skies, etc. Therefore, the skier can as smoothly and easily ski in an artificial skiing area as in a natural skiing area.

Title: Cathode-ray tube display device
Inventor: SATO YOSHIMI
IPC: H04N3/26
Filed: 1986-12-26
Abstract: PURPOSE:To attain a just focus corresponding to illuminance even if it varies by varying a prescribed grid voltage, and adjusting the illuminance of an image or a pattern displayed in a cathode-ray tube. CONSTITUTION:A G4 voltage control circuit 7 functions as a focus voltage control mans, and lowers the fourth grid voltage G4 of an electron gun 2 when the illuminance is at a high level at the time of receiving a first grid voltage sk, but rise the voltage G4 when the illuminance is at a low level. This means that if the movable terminal of an illuminance volume 6a is moved to pulse-side, the first grid voltage becomes higher, and the illuminance of the image in the cathode-ray tube is increased. The rise of the first grid voltage sk causes a collector current flowing through a NPN-type transistor Q2 is increased, both collector voltages of the transistors Q1, Q2 drop, and are impressed to the fourth grid G4 as a fourth grid voltage to provide a just focus corresponding to the illuminance.

Title: Manufacture of thermal head
Inventor: ARISAWA HIROSHI
IPC: B41J2/35
Filed: 1989-11-30
Abstract: PURPOSE:To apply a confronting-type arrangement of electrodes while maintaining a sufficient interval between the electrodes by supplying a pulse current between a common electrode contacting part and an end part of an independent electrode, and partially lowering the resistance value of a heat generating resistance body held between the contacting part and the end part, thereby forming an independent separate heat generating part. CONSTITUTION:When an essential part of a thermal head H is complete, the resistance value of a heat generating resistance body 5 is adjusted according to the pulse trimming method. In order to obtain a definite heat generating part, a pulse current having the pulse width not larger than 1musec is applied between electrodes 3 and 4, thereby partially lowering the resistance value of the heat generating resistance body 5 between a common electrode end part 3b1 and an independent electrode end part 4a confronting to each other. Accordingly, a heat generating part 5a is formed between the confronting end parts 3b1 and 4a. Although the decreasing ratio of the resistance value of the heat generating resistance body 5 is different depending on the material of the heat generating resistance body or baking temperature thereof, if the piezoelectricity and pulse width are suitably selected and applied to all the heat generating parts 5a and, the resistance value at the parts is lowered to 1-2kOMEGA which is 40% or more lowerer than that at the other parts, many heat generating parts 5a are formed at one time with a predetermined distance spaced each other on the heat generating resistance body 5.

Title: Registered character display system
Inventor: MACHIDA MAKOTO
IPC: G09G5/24
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To display registered characters fast on a display device. SOLUTION: This system has a readable and writable storage medium 9 whose storage contents are not erased even after the power source is turned off. In this case, a registered character inputted from a host device 13 is converted by a character outline converting means 4 into outline data, which are saved on the storage medium 9. Consequently, the character is generated from the outline data on the storage medium 9 without inputting generated data on the registered character to the display device 1 again, thereby displaying the registered character on a display medium 14 thereafter. A state informing means 8 can inform the host device 13 whether or not there are outline data on the registered character on the storage medium 9.

Title: Optical receiver
Inventor: YAMAMOTO TETSUO
IPC: H04B10/572
Filed: 1988-12-09
Abstract: PURPOSE:To make the pulse width of an output pulse signal outputted from a comparator stable against a temperature fluctuation by making a relative level difference between the output voltage of an amplifier fed to the comparator and a comparison voltage outputted from a level shift circuit nearly constant against a temperature change. CONSTITUTION:With a prescribed minute signal inputted to a photodetector 1, an output voltage appears at the output of an amplifier 2. When ambient temperature rises, an output voltage EO2 is lowered. On the other hand, a current I0 flowing to the collector of a constant current source transistor(TR) Q1 is increased. As a result, a change in a voltage outputted from a level shift circuit 5 is coincident with a temperature change and a level difference between both is nearly constant against the temperature fluctuation. Thus, the pulse width of an output pulse signal outputted from the output terminal 3 out of the comparator 3 is made stable against the temperature fluctuation.
