Title: Angular ball bearing
Inventor: HONGO WATARU
IPC: F16C25/08
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent an increase in face pressure of a bearing caused by the increase of a number of revolution, by mounting an inner ring comprising a circular groove cut in an axial direction from an end face at an opposite side of a contact part with a ball, and an outer ring comprising a circular groove cut in an axial direction from an end face at a side of the contact part with the ball. SOLUTION: In a bearing 1, the raceway track side parts 2b, 3b of an inner ring 2 and an outer ring 3 are not directly mounted on a main shaft 5 and a housing 6, but the grooves 10, 11 are formed between the raceway track side parts 2a, 2b and the mounting parts 2a, 3a, so that the raceway track side parts 2b, 3b are elasticlaly deformed by the centrifugal force in accompany with the rotation of the main shaft 5, and the diameters are enlarged. Further the centrifugal force is acted on the ball 4 by the rotation, and the raceway track side part 3b of the outer ring 3 is pressed outward in a radius direction by this centrifugal force, whereby it is elastically deformed and the diameter is enlarged. That is, the increase of the face pressure of the bearing 1 can be reduced by the elastic deformation of the raceway track side parts 2b, 3b of the inner ring 2 and the outer ring 3.

Filed: 1987-12-01
Abstract: PURPOSE:To enable performing setting operation on the site, if an operation member is available, by transmitting setting signals based on radio signals from said operation member when setting an operating status of equipment. CONSTITUTION:If an operator places an operation member 30 within reach and operates a switch for an operational key 32 or the like, a setting signal will be generated at a signal generation member 33. This setting signal is converted into an infrared ray signal, then transmitted from a light transmission member 33a. At this time, setting status, such as preset temperature is displayed on the liquid crystal on a display member 34 based on the predetermined conditions. On the other hand, a signal transmission member 21 analyses signals transmitted from a control device 13 by the electric power supplied by way of a connection cable 2 and the control status is displayed on a display member 24. When the infrared signals from the operation member 30 are received at a signal reception member 25, the setting signals are analysed and transmitted to a signal conversion member 23, where they are modulated to a specified carrier wave and transmitted to the control device 13 from the connection cable 2. The control device 13 analyses the setting signals and controls a burner 13, responding to the setting status.

As a result, a damper is formed, and the impact force is reduced. And when the components 1a and 1b are separated, the cooling material flows in through the clearance, and a damper effect in the same way can be obtained.

IPC: H03G3/30
Filed: 1986-12-24
Abstract: PURPOSE:To prevent malfunction of a gain control circuit in response to an offset control circuit by adding a band limit circuit to the gain control circuit. CONSTITUTION:An input signal is inputted to a variable gain amplifier 1 and outputted from an output signal terminal 8. The variable gain amplifier 1 is added with the offset control circuit 2 to compensate the deviation of the operating point due to the input offset fluctuation and the DC fluctuation caused equivalently at the output signal terminal 8 is fed back to the input side to apply offset control. A clamp circuit 3 clamps high or low level of the output signal and since the offset fluctuation by the operation of the offset control circuit 2 is added to the signal, then the fluctuation component is eliminated by a band limit circuit 4. Then the signal peak value by a peak value detection circuit 5 is detected, it is compared with a reference signal amplitude by the gain control circuit 6, the difference signal is amplified and integrated and inputted to the variable gain amplifier 1 as the gain control signal. Thus, the gain control circuit does not receive the effect due to offset fluctuation and no malfunction takes place.
