Title: Applying method of control signal in analog switch circuit
Inventor: YASUHARA HAJIME
IPC: H03K17/687
Filed: 1982-07-22
Abstract: PURPOSE:To prevent the generation of distortion, by setting the level of a control signal in the state, where an FET is turned on, so that this level does not exceed the forward voltage even for a high-level input signal in an analog switch using the junction FET. CONSTITUTION:In case the high-level input signal is given to a terminal P1, a current is flowed from a gate G to a drain D to generate a distortion in the output signal if the potential of the input-side drain D exceeds the forward voltage for the potential of the gate G near the negative-side peak. In this case, when a resistance R4 is inserted between the emitter of a transistor TRQ and a reference voltage, the potential of the input-side drain D does not reach the forward voltage of the FET even when the difference between the potential of the gate G of the FET and that of the input-side drain D is maximum. Consequently, no current is flowed from the gate G to the drain D, and the distortion is not generated in the output signal.

Title: Water-level detection apparatus
Inventor: KITAJIMA HARUO
IPC: G01F23/60
Filed: 1992-04-22
Abstract: PURPOSE:To prevent a relay contact from being chattered and to simply change a set water level by a method wherein a flaot in which a magnet is installed is moved up and down along a pole, a movable piece by which the magnet is attracted to the pole is installed and the position setting means of the movable piece is installed. CONSTITUTION:When a capsule 15 is moved, it is moved by pressing a pole 12 by means of a finger. The pole 12 is fixed at a proper height, the capsule 15 is moved inside the pole 12 and a movable piece 16 is set at a set water level. When a water surface 8 rises, also a float 11 rises by being guided by the pole 12. When the water level rises up to the position of the movable piece 16, the movable piece 16 is attracted to a magnet and contacts 17b, 17c are connected via the other end of the movable piece 16. An electric current is applied to a relay 6 at a detector 5 through lead wires 3; a contact 7 is closed; a detection signal is output. Even when the water surface 8 is vibrated up and down in this state within a range down to the lower part of a magnet 14 from the magnet 13, the contact 7 at the relay 6 is not chattered because the movable piece 16 is attracted to the magnet 13. The magnet 14 in which the water level is situated at the lower part than the set water level attracts the movable piece 16 and resets the relay 6, and it is detected that the water level is at the set water level or lower.

Title: Flip chip junction inspection method and device
Inventor: NAGAO MASAHIKO
IPC: H01L21/66
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To detect defective junction such as peeling of the pad of a semiconductor device whose difference does not appear in the quantity of penetration of X ray, or a junction trouble such as a pad cracks, etc. SOLUTION: The inspection is carried out of the following steps; illumination having wavelength in the band of infrared ray wavelength is applied (4) from right above the opposite side to the junction of a semiconductor device, and an image is taken in with a camera (1) which is attached coaxially with the illumination and has sensitivity in the band of infrared ray wave length. The infrared ray wavelength penetrates the silicon layer of the semiconductor device of flip chip mounting, and is reflected at the aluminum pad face, so the camera can take in the image of the aluminum pad face. In the case that there is a damage in the pad of the semiconductor device, it becomes a different image from a normal pad, so the faulty place can be found out visually by indicating the image taken in from the camera on a monitor (5).  Moreover, the damage on the pad can be automatically detected by processing and computing the image taken in from the camera, so that the difference may come out in the measured value between a normal pad and a faulty pad.

IPC: G06F12/00
Filed: 1992-05-21
Abstract: PURPOSE:To shorten a registering time by changing the procedure of file registration and efficiently executing reorganization at the time of registration. CONSTITUTION:An input part 1-1 transmits a command inputted by an operator to a control part 1-2. The control part 1-2 requests deletion to a member deleting processing part 1-3. The processing part 1-3 deletes all already registered members out of members to be registered. The control part 1-2 requests a file inspecting part 1-6 to check whether all members can be registered or not even if reorganization is not executed. When the result of the inspecting part 1-6 is 'unregistrable', the control part 1-2 requests reorganization to a reorganization processing part 1-5 to make a file registrable state. Then the control part 1-2 requests a member registering part 1-4 to register all members specified by the input part 1-2 in the file 107.

IPC: G11B20/12
Filed: 1983-07-15
Abstract: PURPOSE:To prevent the confusion of data writing control of a storage device by writing two identifier (ID) data in one block. CONSTITUTION:When the writing of write data is completed, a write length arithmetic circuit 20 sends a clear signal to a buffer register circuit 16 to clear the circuit 16, and then writes erasure data ''00'' successively in an erasure data part 21 within a range specified by a write control signal 5 as the erasure data. A host controller 13 when receiving an end report from a control part 14 ends the operation mode of the ID data writing. Write data in the ID part 2 that the host controller 13 sends to the magnetic disk device control part 14 contains no erasure data, and this data is generated by the control part 14. Consequently, the confusion of the data writing control of a storage device resulting from that two ID data are written in one block is prevented.
