Title: Double end swash plate compressor
Inventor: KIMURA NAOFUMI
IPC: F04B27/08
Filed: 1995-06-29
Abstract: PURPOSE: To make reduction of a consumption power compatible with suppression of vibration by a method wherein a plurality of disc springs are located in parallel combination with a thrust bearing between a pressure receiving seat formed at the boss part of a swash plate and a pressure receiving seat formed at the support part of a cylinder block. CONSTITUTION: When the two boss parts of a swash plate 5 are nipped by a cofastening member, containing two cylinder blocks 2 and 3, through thrust bearings 6A and 6B and disc springs 7 and 8, an axial fastening margin is absorbed by a buffering function based on resilient deformation adherent to the disc springs 7 and 8. During load speed operation, the disc springs 7 and 8 are easy to effect relative rotation as a complete different body and since support rigidity of the swash plate 5 based on a total of the repulsion forces of the disc springs 7 and 8 is low, a consumption force during low speed operation is reduced.  Meanwhile, during high speed operation, the disc springs 7 and 8 are integrally formed and relative rotation is hard to make and since support rigidity of the swash plate 5 based on a repulsion force exceeding a total of the repulsion forces of the disc springs 7 and 8 is high, vibration and noise of the swash plate 5 are suppressed.

Title: Comparator
Inventor: GOTOU MAKOTO
IPC: H03K3/02
Filed: 1982-09-21
Abstract: PURPOSE:To prevent a distortion from being produced on an input signal, even if an input source having a high output impedance is connected, by providing a hysteresis circuit not giving any effect on the input signal between a differential comparing section and an output section. CONSTITUTION:The differential comparing section 1 inputs a current i1 in response to an input AC signal to a current mirror circuit 3, which inputs a substraction of a current 2i1 from a constant current I0 to a current amplifier circuit 4. The current amplifier circuit 4 and the feedback circuit 5 produce an equivalent hystersis characteristic, and a current i3 proportional to an output current i2 of the amplifier circuit 4 is fed back to the input of the amplifier circuit 4. The hysteresis is produced without giving any effect on the AC input signal through the constitution above. Thus, even if a signal source having a high output impedance is inputted, the generation of distortion to the signal is prevented.

Filed: 1992-06-23
Abstract: PURPOSE:To improve the bandgap profile and the short-circuit current by forming a highly light absorbent layer in an 'i' layer within a range of 80nm from a 'p' layer. CONSTITUTION:In order to improve a short-circuit current, a highly light absorbent layer 7 having a bandgap of 1.34eV and a width of 2nm is formed from the position, which is spaced at an interval of 15nm from the end of an 'i' layer, on a 'p' layer side that serves as a light receiving surface. A bandgap between the 'p' layer and the 'n' layer is 1.75eV, and the minimum part 12 of a bandgap profile, except for the layer 7, is spaced at an interval of 40nm from an amorphous carbon 'p' layer 8 on a 1.42eV-light receiving surface side. A film-thickness 11 of the 'i' layer is 250nm. Both ends of the layer 7 are smoothly connected with the bandgap profile. Although the highly light absorbent layer is spaced at an interval of 15nm from the end of the 'i' layer on the 'p' layer side, the layer should be positioned within a range of 80nm in order to improve reliability by means of the light absorbent layer. The fact that reliability is improved by disposing the minimum bandgap of the bandgap structure within a range of 80nm is indirectly induced from experimental facts.

In the circuit 42, a d.c. level from the circuit 38 is received with a comparing circuit 68 and compared with a reference level Vref selected in a switching circuit 62. In the circuit 68, when the level of an input 40 obtained at the central position of the track exceeds the threshold Vref, the output of the circuit 68 is made into a significant output. The circuit 24 decides that a video signal is recorded at the track position by the significant detected signal. The circuit 24 similarly detects an inner track.
