Title: Throttle grip switch device for two-wheeler
Inventor: UEHARA YUKIYASU
IPC: H04B1/04
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To make communications smoothly and safely by installing a talk transmit switch on a throttle grip on the side with rider's right hand. SOLUTION: When a rider talks with a wireless communication device, he leaves the middle finger on a front brake lever B, bends the forefinger and puts inside the brake lever B, and keeps talking while the forefinger pushes a talk transmit switch S continuously. The individual fingers of the right hand have greater margin than those of the left hand. Owing to provision of the switch not beside the grip to be grasped by the right hand but on the grip itself, the relative positional relationship between the right hand fingers and the switch remains unchanged to whichever angle the right hand turns the grip within its movable range. Accordingly the switch can be manipulated stably by using any finger easy to move effectively, for example forefinger of right hand, so that easiness in handling is ensured and radio communications can be conducted smoothly and safely.

Title: Multicap magnetic detection head
Inventor: MARU HIROSHI
IPC: G01D5/245
Filed: 1985-05-09
Abstract: PURPOSE:To enable the lowering of hysteresis with a reduction in the through magnetic flux density, by setting the distance between adjacent head gaps at nlambda/2 [wherein (n) is odd number of 3 or more] with the magnetic wavelength for a magnetic scale as lambda. CONSTITUTION:A magnetic flux detecting section B is designed with attentions paid to the fact that the same operation is secured with a head based on the function thereof of adding magnetic fluxed phi opposite to each other as far as the distance between adjacent had gaps corresponds to 1/2lambda in the magnetic potential relationship. If the distance between the adjacent gaps is nlambda/2 [wherein (n) is odd number of 3 or more], the core of the head can be made thick enough as desired without disturbing the magnetic scale signal. This also can lower the hysteresis sufficiently with a reduction in the core-through magnetic flux density keeping the head detection signal level the same as ever. In this case, the gap length ranging 0-lambda/2 can increase the head detection signal level. For example, when the gap length is set at lambda/2 that could maximize the output level, the head detection signal with a large level can be obtained with limited number of gaps.

Title: Lead glass for radiation protection
Inventor: UKAI MASAMI
IPC: G21F1/06
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To prevent the direct sticking of free water to the surface of lead glass and to prevent yellowing by forming a transparent film of silica on the surface of the lead glass. SOLUTION: A transparent film 4 formed on the surface of lead glass 1 may comprise any material if the material blocks interrupt the direct contact of the surface of the lead glass 1 with the external environment and has transparency but a film of silica is adopted from the viewpoint of the denseness, hardness and adhesion of the film and the antireflection of the glass surface. The transparent film 4 preferably has a refractive index close to that of the lead glass 1 because strong interference color is developed in the transparent film and impairs the appearance of the glass in the case of remarkably different refractive indexes. The thickness of the transparent film 4 is preferably <=0.5 μm. In the case of >0.5 μm, interference fringes are formed on the surface of the glass and impair light transmittance.  Though a higher baking temperature gives a denser film in the formation of the transparent film 4, the lead glass 1 is deformed at a baking temperature above the strain point (450 deg.C) of the glass, accordingly the baking temperature is preferably set at the strain point or below.

Abstract: PURPOSE:To enable removal of an interference wave having a long time interval by a method wherein the leading edge of a received signal is extracted as a signal of distance to the signal and then the correlation of this distance signal is taken out. CONSTITUTION:A received signal al based on the 1st transmission is sent into a pulse-forming circuit 1 and formed in such a way as pulse signals A'11 and A'12 which show a high level only in the period when signals A11 and A12 are present. The signal A'11 is sent in a distance-signal generating circuit 2 and there a distance signal D11 is generated, while a distance signal D12 of the signal A12 is generated in the similar way, and they are stored one by one in a memory circuit 61 by a clock pulse C. And, by the n-th detection, distance signals are stored sequentially in such a manner that the 1st distance signal d1 is stored in a memory circuit 6n and the n-th distance signal dn in the memory circuit 61. When the n+1st transmission is conducted, the distance signals d1-dn are sent in a logic circuit 7 based on the clock pulse C and thereby an output waveform e is obtained. Thus, an interference wave is removed completely.

Title: Magnetic disk device
Inventor: TAGAWA NORIO
IPC: G11B21/21
Filed: 1985-05-10
Abstract: PURPOSE:To float stably a magnetic disk device even with a magnetic recording medium of a small diameter by using a negative pressure slider magnetic head having the width of the positive pressure generating slider at the inner circumference side of a magnetic recording medium of a negative pressure slider set larger than that at the outer circumference side of the magnetic recording medium. CONSTITUTION:For two negative pressure slider magnetic heads, the slider width (b) at the inner circumference closer to the center of a recording medium is set larger than the slider with (b) at the outer circumference side between two existing sliders on the positive pressure generating surface. Thus it is pos sible to compensate greatly the reduction of the floating force of the slider at the inner circumference side produced by a low peripheral speed. This prevents such a case where the slider floats with sloping produced totally in the rolling direction and therefore attains a stable thin film lubricant state. As a result, the reliability of a magnetic disk device is improved.
