Title: Picture signal correcting circuit
Inventor: MAEDA MAMORU
IPC: H04N1/107
Filed: 1979-06-29
Abstract: PURPOSE:To avoid the amount fluctuation of the incident rays and then eliminate the uneven density, by providing the mark of the reference density at part of the original illumination position and then giving correction to the picture signal level based on the density signal. CONSTITUTION:The mark is attached to the roller, and the mark sensor detects the mark to know the shift amount of the scanner. In other words, control circuit 62 is reset with reception of start signal ST, delivers the sampling signal by the subsequent scanning clock SC and holds the value of picture signal VO to sample holder 63. This value is supplied to dividing circuit 64 until the arrival of the next sample holding command. Circuit 64 gives the reciprocal conversion to the hold value of holder 63 with reference input (e) set to 1, and the hold value is supplied to input terminal Y of multiplying circuit 61 in the form of the correction signal. As a result, output signal VON of circuit 61 is turned into the signal of the normal level which is obtained by eliminating the effect of the fluctuation of the scanning speed from picture signal VO.

Title: Liquid cooled electric rotating machine
Inventor: KAWABATA KAZUAKI
IPC: H02K9/19
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the shear at a rotation detecting section even when a hollow shaft carrying a rotor is thermally elongated to the load side by mounting the rotation detecting section on the opposite side to the load. SOLUTION: A rotation detecting section 11 is mounted on the outer circumferential part of an outer cover 3 for a bearing housing 2a on the opposite side to a load. A gear or a slit disc 12 for detecting the rotation is carried on a hollow shaft 5 at a position corresponding to the rotation detector 11 on the opposite side to the load. A mechanical seal 7 is disposed on the farther outside of an outer cover 3 for the rotation detector 11 and fixed while being spaced apart from the gear or slit disc 12 for detecting the rotation. Even if the hollow shaft 5 is thermally expanded to cause elongation of the load, the opposite side to the load is not elongated because it is cooled with a cooling liquid, and thereby the r.p.m. of motor can be detected accurately.

Title: Decoding circuit
Inventor: UEHARA HIDEO
IPC: H04L25/49
Filed: 1985-04-19
Abstract: PURPOSE:To obtain a fixed decoding signal by controlling automatically the phase uncertainness of a clock of a clock producing circuit after dividing the clock. CONSTITUTION:An exclusive OR circuit 51 obtains an exclusive OR between a received CMI code 2 and a signal 3 which is delayed by a bit through a delay circuit S1. Then said OR is sampled with the fixed timing and inverted for production of a decoding signal. Therefore an exclusive OR circuit 52 obtains an exclusive OR between a division signal 6 produced by a flip-flop circuit F2 of the 1st clock (2f0) 5 and a signal 7 which underwent the waveform shaping at the rise of the code 2 via an inverter 53 and an FF circuit F3. This exlusive OR is always sampled with fixed timing. Thus it is possible to obtain a decoding circuit which is free from such a case where the NRZ signal or a clock has the advance or delay by a bit in terms of time.

Title: Piezo-electric humidity sensor
Inventor: UCHIYAMA FUTOSHI
IPC: G01N27/00
Filed: 1980-06-18
Abstract: PURPOSE:To achieve a stable measurement of humidity with the oscillation of a vibrator stopped at a desired humidity by specigying the thickenss of a film of a hygroscopic material coated on a piezo-electric vibration plate to ensure a proper combination with the required vibration mode at a given humidity. CONSTITUTION:A hygroscopic material such as polymide is applied on the surface of an electrode 2 provided on the surface and the back of a rectangular piezo- electric vibration plate to 1 form a hygroscopic material film 4. Changing the thickness of the elctrode 2 reduces the main vibration frequency of the vibration plate 1 in proportion to the thickness thereof, so that the frequency in the unwanted vibration mode little changes. On the other hand, absorbing the humidity with the film 4 substantially changes the thickness of the electrode 2. Therefore, when the thickness of the hygroscopic film 4 is selected so that the main vibration mode is properly combined with the undesired vibration mode, a hmidity according to the film 4 increases the euivalent resistance of the vibration plate 1 so suddenly to halt the vibration thereby assuring a stable measurement of humidity.

Title: Automatic zoom camera
Inventor: KUNISHIGE KEIJI
IPC: G02B7/08
Filed: 1991-04-15
Abstract: PURPOSE:To execute photographing at desired photographing magnification and to prevent a shutter chance from being lost by driving a zoom optical system based on a focal distance output and stopping the driving thereof when it reaches the position of the focal distance. CONSTITUTION:When a 1st release switch becomes in an on-state, routine is shifted to the subroutine of range-finding (S1). Then, a range-finding action is performed by a range-finding part to obtain an object distance. When the data on the result of the range-finding is stored, whether a mode is an automatic zoom mode or not is checked (S2). In the case that it is the automatic zoom mode, a target focal distance (f) is calculated based on previously set imprinting magnification (S12). Next, tolerance K is decided based on the variation of the target focal distance (f) (S13). Continuously, a zoom value being a current focal distance is compared with the focal distance (f) of the target position of automatic zoom obtained by calculation (S14). When they are nearly coincident, it is judged that the optical system is at the desired automatic zooming position.
