Title: Device for making electronic-parts carrier
Inventor: KURAMOCHI SADAO
IPC: B65B47/06
Filed: 1989-06-06
Abstract: PURPOSE:To produce an electronic-parts carrier with an excellent seal by forming an overlay of Teflon on the surface of a sealing head on the side coming in contact with a cover so as to level the contact surface of the sealing head of metal. CONSTITUTION:An electronic part 17, such as an IC, is deposited in each of receptacles 12 in a bottom member 11. A cover 15 then is laid on the bottom member 11 and pressed against and put in tight contact with the flanges 13 of the bottom member 11 by a rolling roll 5. Next, sealing heads 3 are brought upon supporting rubber 2 so that the attachment of the cover 15 to the flanges 13 of the bottom member 11 is secured by heat sealing between the supporting rubber 2 and Teflon tapes 3a on the sealing heads 3. An electronic-parts carrier 10 is formed in the manner mentioned above. Since a Teflon tape 3a is attached to the surface of a sealing head 3 on the side coming in contact with the cover 15, a level surface for the contact can be formed on the sealing head 3 which is of metal. A good tightness that results between the sealing head 3 and the supporting rubber 2 ensures satisfactory heat-sealing.

Title: Measurement system for charge beam shape
Inventor: OSADA TOSHIHIKO
IPC: H01L21/027
Filed: 1978-11-21
Abstract: PURPOSE: To attain precise measurement by eliminating an influence of noises by converting an analog signal, outputted by a charge beam detecting method, into a digital signal and then by differentiating the contents of cumulative storage of a cumulative storage method.  
     CONSTITUTION: Electron beam 2 is shaped by passing through rectangular slit 3 and made to scan on shielding member 5 through deflector 4. A beam reflected by shielding member 5 is detected by detector 6, amplified and then differentiated by digital differentiator 13 after passing through analog-digital converter 11 and cumulative memory unit 12, thereby measuring waveform width W p . As a result, a waveform with superposed noises is digitally converted and stored in comulative memory unit 12, and those operations are repeated several times to cancel noises generated at random. Consequently, an analogically-converted signal has few noises and waveform width W p  can be measured accurately.

Title: Sewing machine having upward feed apparatus
Inventor: KURUTO KURUNTO
IPC: D05B27/04
Filed: 1988-06-13
Abstract: PURPOSE: To reduce both size and mass of the relative motion of a transmission element by including a position where a lever arm and a driven joint plate form a straight line in the vibration range of a triangular lever for the angle position of the lever arm connected to sewing legs. CONSTITUTION: By the rotary swing of the triangular lever 34, the vertical motion of the two sewing legs (upper feed leg 6 and cloth presser 1) and the pressurizing force of the sewing legs added to a cloth are formed. At this time, the pressurizing force is supplied by the pressure of the springs 25 and 54 of the two sewing legs and the pressure through a carrying device 59. For the vibration motion of the lever arms 34b and 34c generated by the turning vibration motion of the triangular lever 34, at the time of adjusting elevation drive to be small, the amplitude of elevation becomes flat in the state of placing the two sewing legs 1 and 6 on the cloth. That is because the two lever arms 34b and 34c are operated at the position for forming one straight line with the respective joint plates 44 and 46 at the time.

Title: Controller for synchronous motor
Inventor: NASHIKI MASAYUKI
IPC: H02P25/08
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To provide good controllability and high efficiency at a low power consumption for a reluctance type synchronous motor. SOLUTION: In an armature current limiting processing section 11, a limit is applied to a pre-limit torque command ST depending on the detection speed SPD at that time, and a torque command STC is calculated. On the other hand, at the field current processing section 12, a pre-correction field current command value SF is reduced when the speed has a high response to the detection speed SPD. Also, based on the pre-limit torque command ST at that time, a coefficient Kτ, which increases when the torque command is large, is calculated. Then, a field current command is calculated with SFC=Kτ*SF. The current command processing section 3 generates a current command based on a torque command STC supplied and drives a motor 5 through a current control section 4.

Abstract: PURPOSE:To simplify the structure of a precision fine adjustment unit by hanging a single spring which applies pushing pressure to each engagement point on the surface of a stage which can be moved on an X-Y plane and the surface of a base bench, while setting its hanging angle to a specific value. CONSTITUTION:A precision fine adjustment unit which is used in electron microscopes is provided with action points at symmetric positions with respect to the reference axis of a stage 1 which holds a sample. An X direction transfer mechanism engages with one point and a Y direction transfer mechanism engages with the other point so that the center of the stage can stay constantly in spite of any temperature change. Besides, a tension spring 8 which enages with the stage 1 is provided on a base bench, such as a sample room wall, etc. by making its hanging angle theta almost equal to an angle given by tantheta=1/2. As a result an uniform surface pressure can be applied on each guide surface, by using only one tension spring 8 for the stage 1 and eliminating springs for other sections and the structure of the precision fine adjustmwnt unit can be simplified.

Filed: 1986-06-20
Abstract: PURPOSE:To cancel a temperature drift and to secure a stable gain control action by providing a feedback loop to detect the synchronizing level of an output video signal and send it to the gain control terminal of a variable gain control circuit. CONSTITUTION:When a changeover switch 16 is connected to a terminal (a) to be selected, the synchronizing level VL of an input video signal detected by a synchronizing level detector 15 is sent to a multiplier 17 and multiplied by the gain control input X received from a terminal 5. Thus the gain can be controlled regardless of said level VL. When the switch 16 is changed over to a terminal (b) to be selected, the reference voltage V0 received from a reference voltage source 18 is sent to the multiplier 17. Then the input X is multiplied by the fixed voltage V0 and sent to a comparator 12. Thus it is possible to easily attain such an action for keeping automatically the gain at a fixed level.
