Title: Torque limiter
Inventor: FUJIOKA TERUO
IPC: H02K49/00
Filed: 1993-06-17
Abstract: PURPOSE:To reduce a torque ripple by combining a liquid lubricant and a solid lubricant as lubricants added to a sliding section between a first shaft and a second shaft. CONSTITUTION:Silicone oil(SO) as a liquid lubricant and fluororesin powder(FP) as a solid lubricant are combined in the sliding sections 10, 11 of a first shaft 1 and a second shaft 2. It is faborable that the viscosity of SC12 is brought to a value from 50cst to 1000cst. It is preferable that FP13 having a mean particle size of 207mum or less is used. FP13 is attracted and held uniformly to the first shaft 1 by electrostatic force, and dispersed equally to the sliding sections 10, 11 by S012. Accordingly, the combination system of FP13 and SO12 functions as a ball bearing, thus sufficiently reducing a torque ripple.

Title: Nonlinear circuit
Inventor: MINAMIBATA SHIGEAKI
IPC: H03G11/08
Filed: 1983-08-12
Abstract: PURPOSE:To attain excellent accuracy in the nonlinear characteristic of input versus output relation and also a desired nonlinearity easily by changing the number of transistors (TR) activated as diodes provided in a current path of the 1st and the next stage amplifiers so as to control the amplification characteristic with nonlinearity. CONSTITUTION:In order to attain the desired nonlinearity characteristic, n-set of TRs are employed actually as TRs Q3, Q4 and Q5, Q6. When an input signal Vin is applied, a current I1 flows to Q3, Q4, Q1 and a current I2 flows to Q5, Q6, Q2. Denoted the ratio I1/I2 as 1:X1, then an output voltage DELTAVT appearing between output lines A and B is decided by equation DELTAVT=nhlnX1. In order to obtain a desired nonlinear characteristic, m-set of TRs are employed actually as TRs Q13, Q14 and Q15, Q16. When a TRQ11 is turned on with the output voltage DELTAVT, a current I11 flows to the Q11, Q13, Q14 and a current I12 flows to the Q12, Q15, Q16. Denoted the ratio I11/I12 as 1:y, then the value (y) is obtained as y=X1(n/m).

Title: Digital display type electronic watch
Inventor: YAMANAKA NORIO
IPC: G02F1/133
Filed: 1977-12-07
Abstract: PURPOSE:To reduce consumption of power source by intermittently lighting a lamp without continuously lighting the same when the lamp is lighted by switching of an external switch. CONSTITUTION:When an external switch 10 is switched, the signal having been inputted to an AND gate 11 changes from 0 to 1 and only when the signal from a frequency dividing circuit 7 is 1, the AND gate 11 goes ON, along with which a transistor 12 also goes ON. Then, current flows to a lamp 9 to be lighted. When the signal from the frequency dividing circuit 7 is 0, the AND gate is OFF and current does not flow to the lamp 9, thus the lamp is off. Hence, if the signal outputted  from  the frequency dividing circuit 7 is 1 Hz, it turns out that the lamp 9 repeats  lighting of 0.5 second and putting out of 0.5 second. In this way, the consumption  of power source by lamp lighting may be made about half.

IPC: G06F3/06
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To increase the number of recordable/reproducible contents to that suited to the average transfer speed of a disc by setting each information block to a block size so that time required for recording and reproduction is constant according to the transfer speed of a storage zone thereof. SOLUTION: The contents 101 are divided into fixed sizes of blocks 102. The sizes of a blocks 102 are varied per zone so that time required for the recoding and reproduction of the blocks in the respective zones is almost equal. The size of the blocks to be stored into the zones on the inner circumference side with a lower delay speed is made smaller while the size of the blocks to be stored into the zones on the outer circumference side with a higher delay speed is made larger. The blocks are arranged in a form arrayed radially from the center of the disc. When the recording area is used being divided by the same angle whether the blocks belong to the outer circumference area, the middle circumference and the inner circumference, the areas can be consumed at the same rate thereby enabling the maximization of the memory capacity.

Title: Clock extracting circuit for data receiver
Inventor: TAKEUCHI YASUSHI
IPC: H04L7/00
Filed: 1980-10-23
Abstract: PURPOSE:To prevent a bit error rate from extending to the largest rate in the region of a high C/N, by detecting one bit synchronizing part for every data group to generate a band switching signal and preventing the bit synchronizing detection in the same group hereafter. CONSTITUTION:A bit synchronizing part BS of the first data in each data group is detected by a detecting circuit 2 to generate a band switching signal CS2. After the band switching signal CS2 is generated once, the detecting circuit 2 does not restart the detection operation for the bit synchronizing part BS until a time corresponding to a data group length N.L elapses by the function of a counter 10. A PLL1 is changed to the state of a high Q value when the band switching signal CS2 is generated once, and the PLL1 holds this state to output a clock pulse of a high stability. Even if the band switching signal is outputted erroneously by the influence of a noise or the like, the band switching signal is not outputted again for the same data group, and the PLL1 outputs the clock pulse of a high stability, thus preventing the bit error rate from extending to the largest rate.
