Title: Magnetic disk device
Inventor: SEO SHUZO
IPC: G11B17/035
Filed: 1986-05-14
Abstract: PURPOSE:To reduce the thickness and size of a device by allowing a hub pressure member to press the center hub of a magnetic disk axially through at the hub forcible insertion position of a lid body through a spring means and leave the center hub at a recording and reproduction position. CONSTITUTION:When the lid body 12 is rotated in its closing direction, the lid body 12 rotates up to the hub forcible insertion position, i.e. its maximum closure position. In this state, a disk holder 13 is given closing-direction force by spring members 61 and 62 on the internal surface of the lid body 12, so the hub pressure member 60 on its internal surface presses the hub 2, which is fitted completely onto the spindle 6 to contact the receiving surface 20 of a hub receiving member 19. Namely, the hub pressure member 60 fixed to the internal surface of the disk 14 through the spring members 61 and 62 with the force which closes the lid body 12 is brought into contact with the center hub 2 to press it, and even when a magnetic disk 1 is pressed to the normal position of the spindle 6, the lid body 12 is stopped by a lock mechanism.

IPC: H01S5/00
Filed: 1995-04-11
Abstract: PURPOSE: To improve crystallinity by forming at least one II-VI compound semiconductor layer on a ZnSe layer on a substrate and setting the defect density of a laminate lower than a specified value thereby lowering the defect density of the laminate. CONSTITUTION: The defect density of a laminate is set lower than 104cm<-2> for an n-type ZnSe buffer layer 43 formed on an n-type GaAs substrate 41. In the initial stage until the thickness of about 10 atomic layer is obtained, the n-type ZnSe buffer layer 43 is grown by setting the ratio of intensity between an Se molecular beam and a Zn molecular beam lower than 1, e.g. 0.7. Subsequently, the intensity ratio is set in the range of 1-1.5 thus obtaining an n-type ZnSe buffer layer 43 of required thickness. With such method, a multilayer semiconductor structure including a ZnSe layer having good crystallinity can be fabricated.

Title: Image pickup device for endoscope
Inventor: SAITO KATSUYUKI
IPC: G02B23/24
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide an image pickup device for an endoscope which enables obtaining of an easily observable image in the case where an object to be observed moves periodically and in the case the object does not move periodically. SOLUTION: It is judged whether an object to be observed moves periodically or not by comparing a voice signal detected by a microphone 10 with an output of a frequency/voltage conversion circuit in a control part 22 as reference value. When any movement is not detected, an LED 16 as lighting means is made to emit light continuously to perform a normal imaging. When any movement has been detected, the LED 16 is allowed to emit light in a pulse train in synchronization with the period of the movement, and the output signal of a CCD 18 is made greater than in the case of a gain control amplifier 29 in continuous emission of light, thereby a brighter image suited for observation is obtained.

Title: Belt conveyer
Inventor: KUBOTA TAKAYUKI
IPC: B65G43/00
Filed: 1992-04-28
Abstract: PURPOSE:To prevent the generation of detecting error due to the deformation of a carrier belt for the constant control of the conveyance amount of articles to be carried per unit hour by detecting the amount of the articles to be carried before the articles to be carried are moved onto a carrier belt from the inside of a hopper. CONSTITUTION:Articles 2 to be carried in a hopper 10 is made roughly uniform by a screw conveyer 11 and guided to a carrier belt 1. At this time, the amount of the articles to be carried which are subjected to a TV camera 13, an image processing means 14 and a computation means 15 is detected. Next, the detection amount is compared with a preset reference conveyance amount to compute the rotational speed of the screw conveyer 11 and send a signal corresponding to the rotational speed to a motor 12. As a result, the rotational speed of the screw conveyer 11 changes, and the amount of the articles to be carried which are guided to a carrier conveyer 1 is regulated so that it may reach the reference conveyance amount.

Title: Mechanical seal
Inventor: WASHIDA AKIRA
IPC: F16J15/38
Filed: 1978-09-08
Abstract: PURPOSE: To raise the vibration resistance of a mechanical seal, the axial moving property and safety of a seal ring and the moving tolerance of a shaft, by W-shaping the cross section of an annular packing which supports the seal ring having a contact surface.  
     CONSTITUTION: The packing 7 has an outer cylinder 14 and an inner cylinder 15, which are set in pressural contact with an inner cylindrical surface 22 and an outer cylindrical surface 24 by push rings 21, 23 and coupled to each other by a diaphragm part 16. As a result, the inside of the seal ring 6 and the outside of the shaft 3 are completely sealed up to each other. Since the diaphragm part 16 is very flexible, the buffer property of the packing 7 is high enough to prevent vibration from being transmitted to the contact surface S. Because the outer cylindrical surface 24 or the inner cylindrical surface 22 slides and/or the diaphragm part 16 is deformed, the axial moving property and safety of the seal ring 6 and the moving tolerance of the shaft 3 are raised.

IPC: G01G23/37
Filed: 1990-04-27
Abstract: PURPOSE:To save power consumption and to start weighing immediately after turning on a power supply by interrupting power supply also from a load cell and an A/D converter. CONSTITUTION:When a power supply switch 5 is turned on, a prescribed DC voltage is supplied from a power supply part 6 to a weighing part 1, the A/D converter 2 and an operation/display part 3. After the lapse of a prescribed time, a signal TB from a timer 34 is also turned to an 'L' level. Thereafter, a final auto-zero processing range AZ.C is set up, and when the difference ¦F¦ of counted data between E and A registers is ¦F¦<=AZ.C, auto-zero processing is executed, the contents of the A register are stored in the E register and zero is displayed on a display device 35. Thereby when the switch 5 is turned off, power supply can be interrupted from all of the weighing part 1, A/D converter 2 and operation/display part 3.

Title: Circuit for detecting interrupted operation of fan
Inventor: SANO YOSHIAKI
IPC: F04D27/00
Filed: 1981-07-15
Abstract: PURPOSE:To detect an interrupted operation of a fan on the basis of an output of a comparator by connecting an input terminal of the comparator to a means  of heating one of a pair of diodes and to both of said pair and providing a fan which sends air to a pair of the diodes. CONSTITUTION:A current ID1 is sent to a diode D1 through a resistance R1 while a current ID2 is sent to a diode D2 through a resistance R2. The voltage- to-current characteristics at the diodes D1 and D2 is shown by (V-1) in the diagram. The current ID1 is set lower than the current ID2. Normally, since a fan is running to feed blow, a voltage VD2 at the diode D2 drops and is kept higher than a voltage VD1. Upon interrupted operation of the fan the diode D2 is heated by the resistance R2 so that the characteristic as illustrated by the (V-I) is shifted to that as illustrated by the dotted line (V-I)' and the voltage VD2 is  thereby shifted to that VD2', on account of which the voltage VD2 is changed  lower than the VD1. By inputting the change into a comparator COMP, an interrupted operation of the fan may be detected.

Abstract: PURPOSE:To prevent dial pulses from being transmitted accurately owing to a noise generated in the operation of a relay, by inserting a dial pulse delay circuit between an exchange and the transmission side of an in-band signal device, and a distortion correcting circuit between another exchange and the reception side of another in-band signal device. CONSTITUTION:To call a telephone set Z' from a telephone set F through a dial pulse transmission and reception system, dialing on the telephone set F is performed, and then dial pulses 3 from an exchange A are delayed through the dial pulse delay circuit D composed of a resistance, a capacitor, and an integrated circuit, and sent out to an in-band signal device B as a signal with a waveform 4. Those pulses are received by the in-band signal device B' on a reception side through a transmission line C, and the regenerated signal 5 is inputted to the distortion correcting circuit E composed of a monostable multivibrator logical circuit. The output of the circuit E is supplied to an exchange A' through a signal line 6 to call the telephone set Z'. Consequently, even if a noise appears on a transmission-side voice signal line 1 during the operation of a relay, the dial pulses are transmitted accurately through the operation of the circuits D and E.
