Title: Gain bandwidth product increase circuit which is used for operational amplifier
Inventor: GERUMAANO NIKORIINI
IPC: H03F3/345
Filed: 1990-04-25
Abstract: PURPOSE: To increase a gain bandwidth product by providing a pair of active elements, a pair of capacitors and an additional input stage at an input stage. CONSTITUTION: The effects of the capacitors CF3 and CF4 works in the direction that eliminates the effects of increasing gain by transistors M3 and M4 as frequency increases. Then, the additional input stage 6 composed of transistors M5, M6, M9 and M10 and a 2nd current generator 2IS are utilized so as to return a zero-point frequency fZ0 to the half face at the left side on an (s) plane, and the zero-point frequency fZ0 moves into a frequency fZ having an approximate value to a pole frequency fp. Thus, the increasing of the gain band width product GBWP in an operational amplifier 1 becomes ten times the value of a unity gain frequency fu by the geometric effects of a differential amplifier stage 5 and the additional input stage 6 provided at the input stage 2. Thus, the gain bandwidth product increases without lowering the stability of the operational amplifier.

Title: Digital signal transmitter
Inventor: SAKO YOUICHIROU
IPC: G11B20/18
Filed: 1982-06-23
Abstract: PURPOSE:To prevent the value of an interpolation output from differing from a real value greatly because of abrupt level variation during the reproduction of a digital-audio signal, by using a received high-order symbol as the high-order symbol of interpolated data when the received symbol is correct. CONSTITUTION:A discriminating circuit 1 discriminates the OR output between pointers PA and PB; when this is at a low level (L), input data WA and WB are correct, so WA and WB are ouputted through a delay circuit 3 and a multiplexer 5. When the OR output is at a high level (H), a pointer PA regarding a high-order symbol WA is checked and when the PA is at the H, the W includes an error, so interpolated data WA' and WB' are outputted from an interpolating circuit 2. When the PA is at the L, the WA and WA' are compared with each other; when WA=WA', it is judged that the interpolated data are not different from real data greatly, and they are used as outputs WA' and WB'. When WA=WA', the WA and a low-order symbol b1 or b2 of specific size are outputted and selected by multiplexers 4 and 5.

Title: Oil separator for a plurality of compressors operated in parallel
Inventor: KATAOKA OSAMI
IPC: F04B39/04
Filed: 1989-04-27
Abstract: PURPOSE:To securely keep an appropriate oil level and at a low cost independent of the condition of the outside air, variation in pressure, or the like by positioning the lower end of a guide plate, which passes the discharged refrigerant gas by a roundabout way, close to the standard oil level of an oil pool in such a manner as to provide a flow velocity- controlling part for controlling part for controlling the flow velocity of the refrigerant according to the variation of the oil level of the oil pool. CONSTITUTION:When the oil level of an oil pool 1a is high, the space between the oil level and the lower end of a guide plate 4 narrows, hence reducing the opening in area of a flow velocity-controlling part 7. As a result, the velocity at which the refrigerant flows past the flow velocity-controlling part 7 increases and the quantity of the oil blown up in drops from the surface of the oil by refrigerant and the quantity of oil drops caught by a second oil separator 6B increase. Simultaneously, the quantity of the oil carried away by refrigerant from an outlet 3 also increases; therefore, the oil level of the oil pool 1a falls. When the oil level is low, the space between the oil level of the oil pool 1a and the guide plate 4 widens, hence enlarging the opening in area of the flow velocity-controlling part 7. As a result, the velocity at which the refrigerant flows decreases and the quantity of the oil blown up and the quantity of the oil carried away by refrigerant decrease; therefore, the oil level of the oil pool 1a rises.

Title: Optical disk device
Inventor: SAKURAI TATSUAKI
IPC: G11B7/095
Filed: 1991-04-15
Abstract: PURPOSE:To enable a stable tracking servo control even when a track pitch is changed by setting the gain of a tracking error signal corresponding to the recording track pitch of an optical disk. CONSTITUTION:The width of a guiding groove GBa formed on the recording face of a recording area OA on the side of outer circumference of the optical disk is set smaller than the width of a guiding groove GBb formed on the recording face of a recording area 1A on the side of inner circumference. Accordingly, the amplitude of the tracking error signal by a laser beam LB gets smaller when the groove GBa is detected than when the groove GBb is detected. Then the gain for amplifying the error signal of when the data of the area OA is accessed is set larger than that of when the data of an area 1A is accessed. Thus, the amplitude value of the tracking error signal can be made constant and the operation of a tracking serbo control system can be stabilized.

Abstract: PURPOSE:To make copying impossible automatically in a double face copy mode if a form whose size is larger than the half of a maximum placing size of an original platen is set, by deciding whether the size of the form is the half of the maximum placing size of the platen or not. CONSTITUTION:If a double face copy mode changeover switch 41 is operated when the machine waits for the operation of a print switch 40, a gate 24 is opened, and a flip-flop 25 is set, and a control circuit 23 is set to the double face copy mode, and a copying program in the mode is executed. The control circuit 23 advances to a step S7 to check whether the form size is A3 or not. If the form size is A3, the control advances to a step S11 to flicker an A3 lamp of a size display device 42 and turns off a ready lamp RL in a step S12. If the print switch 40 is operated at this time, this operation is processed as ineffective, and the copying control is not executed.

Title: Portable fluorescent x-ray analysis meter
Inventor: SATO MASAO
IPC: H05G1/04
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To achieve safe outdoor fluorescent X-ray analysis by using an X-ray bulb instead of radio isotope and securing the safety of shutter opening/closing operation by various kinds of switches and sequence. SOLUTION: When a micro switch 2 of a gripping part 1 is gripped and released, a signal is turned on and off, respectively, on normal carrying. When a micro switch 3 at the tip of the measurement part of an enclosure is brought into and is not brought into contact with a sample 4, the signal is turned on and off, respectively. Then, when no measurement is to be made, a shutter 5 made of a metal with a thickness for completely screening X rays inside a window at the tip of the measurement part blocks an X-ray application port, thus preventing X rays from being leaked outside the enclosure. On measurement, the shutter 5 is opened, primary X rays 7 from an X-ray bulb 6 are applied to the sample 4, and fluorescent X rays 8 peculiar to the element for constituting the sample 4 are counted by an X-ray detector 9.
