Title: Key input device
Inventor: KASHIO TOSHIO
IPC: G06F3/023
Filed: 1988-05-31
Abstract: PURPOSE:To decrease the key operating frequency and to reduce the load of an operator for input of keys by adding the YA, YU and YO keys into a vowel block. CONSTITUTION:A consonant block includes the keys for input of consonants and a vowel block includes the keys for input of vowels. These two blocks are set at the right and left sides on a keyboard. Then the YA, YU and YO keys are included in the vowel block. Thus the input of the contracted sounds are possible with use of the consonant keys and said YA, YU and YO keys. As a result, the key operating frequency is decreased for input of keys and furthermore the key input load of an operator is reduced since the YA, YU and YO keys can be operated in the same way as the ordinary vowel keys for input of the contracted sounds.

Title: Diamond saw
Inventor: KOTANI TAKAHIDE
IPC: B24D5/12
Filed: 1985-06-19
Abstract: PURPOSE:To make it possible to cut such tough material as stone concrete, ceramics, and so on efficiently by providing a saw with a grinding layer made of heat-resistant bond other than copper alloy mixed with diamond particles and slit grooves of nearly zero in width. CONSTITUTION:The outer peripheral edge of a wheel base plate 2 made of carbon tool steel is equally divided into 18 sections making each slit groove 3a nearly zero in width and is provided with a cutting layer 1 of a bond composed of mainly Co, Ni, Fe, and so on, mixed with diamond particles of approximately 30-40 mesh (average; 420mu). The thickness h shall be a little larger than that of the wheel base plate 2. Since the bond is composed of mainly Co, Ni, Fe, and so on, the saw thus produced comes to have such great value of stress even at the temperature of 450 deg.C while in use that any of the tip sections is not removed. And each slit groove 3a is made so minute as to be nearly zero in width that diamond particles and matrices may be prevented from removal due to the breakage caused by impacts.

Title: Laser printer
Inventor: OMURA KUNIHIKO
IPC: H04N1/04
Filed: 1992-05-26
Abstract: PURPOSE:To reduce the width of change of an diode drive current value required to change resolution. CONSTITUTION:A laser light source unit is constructed by installing a laser diode 23 at the focal point of the Fresnel lens using refraction and diffraction phenomena. According to the turning-on and-off of resolution changeover switches S1 and S2, a monitor current flows selectively to variable resistors 54-56 connected to a photo diode 28 for monitoring light quantity. Thus, a feedback voltage to CPU 50 is changed to control the base voltage of a transistor Tr controlling the drive current of the laser diode 23. The temperature change of the laser diode 23 causes the change of an oscillation wavelength when the drive current changes. The fluctuation of the focal length of the Fresnel lens following the change of the oscillation wavelength is expanded through a scanning optical system, and the fluctuation width of the laser beam diameter on the light receiving surface becomes wider than that of the conventional laser printer.

The vertical magnetization recording medium is a Co-Cr film with vertical anisotropy formed by sputtering, and the horizontal magnetizaton recording medium is a gamma-Fe2O3 film formed continuously on the Co-Cr film by sputtering. Both of the recording media are magnetically reversed, and the reversed horizontal magnetization recording component is used in the recording and reproduction of information. The vertical magnetization recording component is considerably reduced as compared to a vertical magnetization recording medium of Co-Cr having a single-layered structure, and when the thickness of the horizontal magnetization recording medium is >=0.01mum, the vertical magnetization recording component is scarcely contained in reproduced wave-form, so any complex signal processing technique is not required during reproduction.

IPC: H04J3/02
Filed: 1988-05-31
Abstract: PURPOSE:To prevent a dry state gate from being destroyed, and to normally transfer data by starting the sending of a digital signal with an output means when the fact that the potential of a highway bus is in a set potential range is detected with a potential supervising means. CONSTITUTION:Means 120 and 121 to impress a prescribed voltage on a highway bus 100, means to change the potential of a selected channel, means 140 and 141 to supervise the potential of the highway bus 100, and means 160-16n to output digital signals to the highway bus 100 are provided. When the fact that the potential of the highway bus 100 is in the set potential range is detected by the potential supervising means 140 and 141, the output means 160-16n starts the sending of the digital signals.

Title: Optical head, focus error detection of which is improved
Inventor: ANSONII JIYOOJI DEUEI
IPC: G11B7/135
Filed: 1990-05-25
Abstract: PURPOSE: To ensure and improve detection of focusing errors in an optical head by providing a prism in the path of a return light beam reflected from an optical recording medium and thereby increasing a divergent/convergent angle. CONSTITUTION: A laser 30 emits such a beam as collimated with a lens 32 and circularized with refraction on the surface 34 of a prism 48. In this case, the surface 34 is applied with the coding of a polarizing beam splitter. The beam 35 thus obtained is guided to a beam bender 38 through an 1/4 wavelength plate and to a lens 40 that focuses on a selectable track on an optical disk 42. A beam 35' reflecting from the disk 42 is returned through a wavelength plate 36 and reflected as a beam 37 from the surface 34 to the surface 44 of a prism 46.  On the surface 44, the width of the beam 37 is reduced, while the divergent/convergent angle is increased relating to focusing errors; if the return beam 35' is coincident with the beam 35, no change is made; if data on the disk 42 is found outside the focal point, the position of the lens 40 against the track is moved so as to be coincident with the data inside the focal point.
