Title: Rolling friction transmission gear
Inventor: HASEGAWA JIYUNZOU
IPC: F16H13/08
Filed: 1982-12-17
Abstract: PURPOSE:To reduce a slide as a whole, by setting up a groove or a concave part on more than one rolling surfaces among any of a rotary shaft, a bearing ring and a friction wheel. CONSTITUTION:Three pieces of grooves 10 are set up parallelly around a rolling surface 5 of a bearing ring 4, and ratios of a maximum contact surface pressure sigma1 between the rolling surface 5 of the bearing ring and a rolling surface 7 of a friction wheel 6 and a maximum contact surface pressure sigma2 between the rolling surface 7 of the friction wheel 6 and a rolling surface 3 of a first rotary shaft 2 are set to 1:0.75-1.33. When these ratios sigma1/sigma2 of the maximum contact surface come smaller than 0.75, a local slide between the rolling surface 5 of the bearing ring 4 being low in the sigma1 and the rolling surface 7 of the friction wheel 6 grow large so that the total slide also grows large. On the other hand, if these ratios sigma1/sigma2 come larger than 1.33, there is the possibility of producing seizure or binding or damage between the rolling surface 5 of the bearing ring being high in the sigma1 and the rolling surface 7 of the friction wheel.

IPC: G09G5/32
Filed: 1990-08-24
Abstract: PURPOSE:To adjust the character line intervals of a document in displaying by providing this character display device with a means for inputting an instruction for adjusting character line intervals, a means for converting the instruction into the number of line interval extending dots or the number of line interval compressing dots and a means for adjusting the character line intervals in accordance with the adjusting instruction. CONSTITUTION:The instruction for adjusting line intervals is inputted from an input means 4. The instruction is converted into dot information for specifying the number of column direction dots by a conversion means 5, and when the inputted instruction is line interval extension, a line interval adjusting means 6 converts the converted dot information into an image signal consisting of non-signals proportional to the dot information and successively scans character intervals with the image signal to magnify the line interval. In the case of a line interval compressing instruction, an image signal corresponding to the converted dot information is deleted from the line interval to contract the line interval. Thus, the character intervals of characters in displaying can be optionally adjusted by the simple operation.

Title: Circuit switching circuit
Inventor: TAKAHASHI YOSHIAKI
IPC: H04B1/10
Filed: 1983-11-30
Abstract: PURPOSE:To suppress pop noises with a single switch even in case all other switches are set under an emergent operation state, by supplying the power to the circuit to be switched by means of one of plural changeover switches and at the same time suppressing the pop noises after detecting that no power is supplied. CONSTITUTION:Trigger circuits 3-1 and 3-2 deliver the muting signals with the input of a level L. A power supply -B is supplied to an AM reception part even in case the lock state is released for switch buttons 1a and 2a. An FM switch button 1a is pushed to obtain a state where a mobile contact C of a switch 1 has no instantaneous contact with both fixed terminals. Then a pulse of a level L is supplied to a trigger circuit 3, and the circuit 3 produces a muting signal to eliminate the pop noises produced when the band is switched. In a normal band switching mode the mobile contact C of a switch 2 has no instantaneous contact with both changeover fixed contacts TS1 and TS2 either. In this case, the anodes of diodes D2-2 and D2-1 are completely separated from both reception parts. Thus a pulse of a level L is applied to the circuit 3-2 with no effect due to the residual electric charge of power supply capacitors at both reception parts.
