Title: Objective lens positioning system for confocal tandem type scan reflection microscope
Inventor: JIYON JIEI MATSUKAASHII
IPC: G02B21/24
Filed: 1989-02-13
Abstract: PURPOSE: To form a required parallax without moving a sample and to obtain a stereoscopic image by monitoring the position of an objective lens by an eddy current sensor, moving the objective lens to two directions, i.e., an axis vertical to an optical axis and an axis parallel to the optical axis, by a piezoelectric element and vertically scanning a focal face. CONSTITUTION: The position of the objective lens is detected by the eddy current sensor and a mechanical input for moving the objective lens is outputted from the piezoelectric element. Output signals from respective sensor converters are amplified and combined with a position corrected input and composite signals are respectively applied to X-axis and Y-axis differential amplifiers. A manual operation input executed by a front panel of a microscope and a position control signal obtained from a remote automatic input generated by a computer are inputted to respective differential amplifiers. Outputs from the differential amplifiers are applied to a high voltage amplifier for driving the piezoelectric element.  Thus, a stereoscopic image is obtained by slightly moving the objective lens in the lateral direction while focusing the lens and forming a required parallax by using the motion of two axes without moving a sample.

When the adjusting panels are set, the first panel 60a is rivetted in the posts. Next, the second panel 60b is drawn from the first panel 60a and the side peripheral plate 64b thereof is forced to contact the peripheral plate of the panel 70 with windows to joint them together with rivets. Moreover, the overlapped part of the first panel 60a and the second panel 60b is also jointed with rivets to increase tightness. For rivetting, rivet holes 18, 69b are previously bored in peripheral panels 12, 64b to contact tight the mutual peripheral panels. In this way, a plurality of panels 10, 60, 70 are jointed to each other.

Title: Portable memory
Inventor: ARISHIGE YUTAKA
IPC: G06F1/00
Filed: 1985-02-21
Abstract: PURPOSE:To prevent the breakdown of data by delivering the corresponding information through a battery voltage checking circuit before it is impossible to hold the data stored in a memory owing to the drop of the battery voltage. CONSTITUTION:A battery voltage checking circuit 8 delivers an abnormal signal to a battery fault output terminal 9 when the voltage of a battery 5 has a drop of such a degree that disables the battery 5 to hold the data stored in a memory 3. An electronic device 7 receives said abnormal signal and detects a fault of a portable memory 6 to discontinue the subsequent data writing actions. This can prevent previously the breakdown of the data in the memory 3 and improves the reliability of the memory 6.

Title: Electronic volume
Inventor: NAKANE HACHIROU
IPC: H03H11/24
Filed: 1982-03-05
Abstract: PURPOSE:To control the output which is connected to a signal input path, by connecting a transistor in parallel to said input path to vary the impedance between the collector and the emitter of said transistor. CONSTITUTION:The resistances 15 and 16 are connected to signal input terminals 20a and 21a respectively. The transistors TR18 and TR19 are connected to the resistances 15 and 16 respectively. A transistor TR17 connected with an emitter via a volume 13 is connected to the base of each of the TR18 and TR19. When the volume 13 is changed, the base currents of the TR18 and TR19 vary in proportion to the emitter current of the TR17. Therefore the signals applied to the terminals 20a and 20a are controlled by the impedance between the collector and the emitter of the TR18 and TR19 and the voltage dividing ratio between resistances 15 and 16. As a result, the signals of the terminals 20a and 21a are controlled just by a single unit of resistance 13 and then taken out to the terminals 20b and 21b respectively.

Title: Cut-off current value command apparatus
Inventor: ISHIKAWA SAKAE
IPC: B60L3/00
Filed: 1987-02-18
Abstract: PURPOSE:To obtain the maximum permissible accelerating force by storing past main circuit current hysteresis and by operating and commanding the maximum cut-off current value tolerable for the apparatus at that point of time. CONSTITUTION:A main circuit current detector 1 detects a main circuit current value and sends the current value to an arithmetic and logic unit 3. Also, a clock 2 sends the present time to the arithmetic and logic unit 3. Said arithmetic and logic unit 3 stores a current value for a past given period of time and obtains a root mean square value of electric current during that period of time and RMS current by said current value. Then, said unit 3 obtains a cut-off current value to be set by said RMS current. The arithmetic and logic unit 3 sends the cut-off current value obtained by said method as a cut-off current value command to a main circuit controller 4. Then, the main circuit controller 4 sets a cut-off current on the basis of said cut-off current value command. In this manner, it is possible to obtain an accelerating force making the capabilities of a main circuit apparatus to the maximum.

Title: Manufacture of foil-wound transformer
Inventor: INUI AKIFUMI
IPC: H01F41/06
Filed: 1988-02-19
Abstract: PURPOSE:To prevent cracks or wrinkling in an insulating sheet, by heating the insulating sheet and cutting off the opposite marginal parts of the lateral direction before winding the insulating sheet over-laid with a metallic sheet. CONSTITUTION:Untreated insulating sheet 1 is heated by a heating means 2 having a width larger than that of the insulating sheet 1. Then, the opposite ends of the insulating sheet 1 are cut off by cutters 3 and the insulating sheet 1 is rolled up round a former 4 to produce an insulating sheet 5. The rolled insulating sheet 5 is overlaid with a metallic sheet and they are wound together to produce a sheet-type transformer. Since the insulating sheet 5 is previously heated to cause strain therein and the opposite ends of the sheet in which the strain is caused are cut off before the insulating sheet 5 is wound together with the metallic sheet to produce a sheet winding, it is possible to prevent cracks or wrinkling in the insulating sheet after formation of the winding.
