Title: Gap correcting device for rolling bearing
Inventor: SUGA YOSHIRO
IPC: F16C19/54
Filed: 1986-06-30
Abstract: PURPOSE:To correct a bearing gap due to a temperature change, and prevent a reduction in bearing performance, by installing a spacer formed of a shape memory alloy having a two-direction characteristic at high and low temperatures between an end surface of a loosely fitted race of a bearing and a side surface of a positioning member opposed to the race. CONSTITUTION:A spacer 60 is installed between a back surface of an outer race 31 of a tapered roller bearing 30 and a side surface of an outer race retainer 11 as a positioning member opposed to the outer race 31. The spacer 60 is formed of a shape memory alloy having a two-direction operating characteristic wherein the spacer 60 becomes an annular member 60a at low temperatures and becomes a disc spring member 60b at high temperature, such a deformation being reversible. Three of the spacer 60 at low temperatures are stacked in such a manner that the direction of deformation is counter to each other. Accordingly, at high temperatures, as the outer race 31 loosely fitted with a housing 10 is pressed by the high-temperature operation of the spacer, the axial expansion of the housing 10 is maintained at an initially set quantity, thus preventing a reduction in bearing performance.

Title: Data transmission fault detection system
Inventor: TOKUNAGA YUJI
IPC: H04L69/40
Filed: 1992-06-12
Abstract: PURPOSE:To improve the fault detection capability when communication is implemented through division transfer of data or the like by outputting fault detection information when any of two parity results outputted continuously indicates both even or odd parity. CONSTITUTION:A data selection means 2 selects alternately an output from transmission registers 11, 12 based on a selection control signal from a data command means 4. Moreover, a data transmission means 3 adds an even/odd number parity bit alternately to its output data and outputs the result to a receiver side. A data reception means 5 at the receiver side receives transmission output data and implements parity check of the received data to latch the parity check results of two consecutively received data respectively. The latched output is inputted to a fault detection means 8, in which whether or not the parity check results of the two consecutively received data indicate alternate even or odd numbers is checked. When the result indicates consecutive even numbers or odd numbers, it is discriminated that reception data error or a sender side data stack error takes place.

Title: Optical scanning device
Inventor: ITO TATSUO
IPC: G02B26/10
Filed: 1990-06-12
Abstract: PURPOSE:To obtain the device which has uniform diffraction efficiency by providing a 1/4-wavelength plate between a semiconductor laser and a hologram disk. CONSTITUTION:When linear deflected laser light is diffracted by a diffraction grating, its diffraction efficiency is maximum when the deflecting surface is parallel to a grating vector and decreases as when the angle between the deflecting surface and grating vector increases. Thus, the diffraction efficiency varies as the hologram disk rotates, so the linear deflected laser light emitted by the semiconductor laser 1 is converted by the 1/4-wavelength plate 10 into circular deflected light, which is made incident on the hologram disk 2 to hold the diffraction grating constant even when the hologram disk rotates, thereby making the intensity of the laser beam 5 constant on a photosensitive drum 4 at all times.
