Title: Magnetic disk device
Inventor: KAIDA KATSUHIKO
IPC: G11B5/09
Filed: 1988-09-22
Abstract: PURPOSE:To prevent the decrease in the peak value of the highest frequency by preventing the interference of a low pass filter by a buffer amplifier, using a lead filter so as to increase the highest frequency component of a readout signal and adjusting the relation of the between a gate channel and a time channel by a delay line. CONSTITUTION:An output signal of an input amplifier 1 passes through a low pass filter 2 and inputted to a time channel and a gate channel respectively. The gate channel is provided with a buffer amplifier 10 and a lead filter 11 and an output signal of the input amplifier 1 is inputted to the buffer amplifier 10. The output of the buffer amplifier 10 is inputted to the lead filter 11 and since the lead filter has a bypass characteristic or a band pass characteristic, the maximum frequency component of the output signal from the buffer amplifier 10 is increased. Thus, a waveform shown in figure is obtained from the output signal of the buffer amplifier 10 at the inner circumferential side with a high recording density by using the lead filter 11. Thus, the peak of the highest frequency is averaged.

Title: Wind direction adjuster of air conditioner
Inventor: TOTSUKA SHINKO
IPC: F24F13/15
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To provide the wind direction adjuster of an air conditioner whose cost is reduced and which is stable in operation by dispensing with conventional adjustment work and facilitating the assembly adjustment work. SOLUTION: A transmission means is made of an engaging projection 13b which projects downward of a change plate 13, and a slot 14a which is made behind the shaft fulcrum 8a of an operation lever 8 pivoted freely of horizontal rotation and engages with that engaging projection. Thereby, the transmission means can transmit the motion of the operation lever 8 directly to the change plate 13 through the engaging projection engaged with the slot, and also absorb the error in attachment of each part by its slot. There is no necessity to adjust the condition of the tension of a connection wire as in the past, and also most parts are set up on an electrical equipment box 7, so this is easy of assembly, and the assembly adjustment time is curtailed sharply.  Moreover, the sliding direction of the change plate 13 can also be freely selected back and forth and right and left, so there is freedom in arrangement of parts, too, and the design property is improved.

Title: Method and apparatus for measuring surface shape
Inventor: KANEKO REIZO
IPC: G01B7/34
Filed: 1988-09-26
Abstract: PURPOSE:To measure the three-dimensional surface shape of every substance by immersing a surface to be measured, a probe, a support spring and the leading end of a displacement sensor in a liquid. CONSTITUTION:A probe 1 is fixed to the leading end of a leaf spring 2 so as to turn downwardly and the leaf spring 2 protrudes horizontally in a cantilevered fashion in such a state that the base end thereof is fixed to the lower end of a sweeping hanging lever 3. The probe 1 slides on the surface of the object 4 to be measured placed on a base plate 5 in a contact state. The radius of the leading end of the probe 1 is formed so as to have a dimension of a sub-micron order or less in order to obtain sub-micron resolving power and, as the leaf spring 2, an extremely thin spring easy to bend is used. A displacement sensor 6 is positioned so that the leading end 7 thereof is faced just above the leading end part of the leaf spring 2 in order to detect the behavior of the displacement of the leading end of the leaf spring 2, and the probe 1, the leaf spring 2, the surface 4a to be measured and the leading end 7 of the sensor 6 are immersed in the liquid 9 received in a container 8. Since the turblent vibration to the leaf spring 2 is blocked and viscous attenuation can be freely given, a surface shape can be measured under reduced load and there is also no possibility destructing the surface to be measured by the sharp probe.

Title: Sensor of low-level rf threshold
Inventor: ARUFURETSUDO AARU KOERU
IPC: G01V15/00
Filed: 1994-10-03
Abstract: PURPOSE: To provide a low-level RF detection circuit which consumes very small power and is not affected by RF noises or fluctuation by providing a circuit for eliminating intermittent low-level RF interferences through detecting low level and varying strength RF signals. CONSTITUTION: An antenna 1 is used for receiving RF signals from a reader. An RF detector 2 converts RF energy provided from the antenna 1 into a DC signal. A transistor 3 is an N-type FET, chops the input DC signal and generates a rectangular wave proportional to that signal. Thus, an RF activating signal and a write data signal can be amplified by using the same amplifier. A signal generated by a rectangular wave generator 6 is passed through a voltage divider formed from resistors 4 and 5, and a low-level threshold reference voltage signal is generated. This reference voltage has a frequency equal to that of the DC signal chopped by the transistor 3 but with opposite polarity.

Title: High frequency front end circuit
Inventor: NAKATSUKA TADAYOSHI
IPC: H04B1/44
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To improve the performance of an equipment together with its miniaturization and cost reduction by making an LNA(low noise amplifier) detour against input of a large signal. SOLUTION: If the input power supplied from an RF input terminal 8 is much smaller than the input saturation voltage of an LNA 1, an RF signal passes through a path 1. Then the RF signal functions to increase the attenuation of an attenuator 2 in response to the input power when the RF input power increases enough and the output power Pout exceeds its upper limit level Pmax and also to control the loss of the attenuator 2 in order to lower the power Pout less than the level Pmax. Under such conditions, the RF signal also passes through the path 1. When the RF input power increases and the power Pout exceeds the level Pmax even with use of the maximum attenuation of the attenuator 2, the RF signal is transmitted through a path 2. An attenuator 3 controls the attenuation of a mixer of the next stage in order to evade the saturation of the mixer.  Thus, it is possible at a high frequency front end part to improve the performance of an equipment together with its miniaturization and with no deterioration of its distortion characteristic even against input of a large signal.

Title: Re-timing circuit
Inventor: USUKI SHIGERU
IPC: H04L7/02
Filed: 1985-10-28
Abstract: PURPOSE:To suppress the jitter of an internal timing lower by controlling a reset reversible counter to be reset so as to restore the count to a reference value thereby ensuring the set bit control. CONSTITUTION:A reception data IN2 including jitter and an internal timing IN1 are fed to the 1st temporary storage circuit 5 via input terminals 20, 30, and whether the signal is retarded or advanced is subjected to sampling detection and the result is stored tentatively. The output signal of the circuit 5 and a reception signal being the result of retarding the data IN2 at a delay circuit 10 are subjected to an operating processing by the 1st NAND circuit 11 and fed to a reset reversible counter 6. When the count reaches a preset bit number, the NAND condition is established in a NAND circuit 12 to generate an output signal. The output signal presets the 2nd temporary storage circuit 2 of the post-stage. Thus, the set bit control is executed surely and the jitter of the internal timing IN1 is suppressed lower.
