Title: Fixed length cutting device
Inventor: TOUJIMA YASUKI
IPC: B26D1/04
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To measure the length of a facing of a TATAMI mat, etc., and cut it automatically and make a standard length cutting device compact by stopping a drive roller and cutting by a cutting mechanism when a length measuring mechanism detects the length which is set in advance. SOLUTION: When a drive roller 18 rotates at a very slow speed, manual rotation by means of a handle 19 becomes impossible. When the driving roller 18 rotates by a specified amount by a motor 21, a knotched section 34a of a slow speed feed disc 34 rotates by a specified angle to turn on a limit switch 35. A control panel 22 stops the motor 21 by the ON signal. A surface of a TATAMI facing 13 which is stopped is cut by a cutting mechanism 36 which can be mounted easily. The cutting mechanism 36 cuts the surface of the TATAMI facing 13 to a specified dimension by a blade 38 which travels to the right and left between rails and rotates.  Since a standard length cutting device 10 which is constituted in this way sends a long object such as the surface of the TATAMI facing 13 manually at first and then conveys it automatically by slow speed feed in the vicinity of the set dimension, the setting of accurate dimension becomes possible.

Abstract: PROBLEM TO BE SOLVED: To make compatibile security and convenience in a system by storing key data, which are acquired through a radio communication means, into a RAM and using these key data as key data at the time of communication with an IC card. SOLUTION: An IC card terminal 10 transmits a terminal ID 11 set for each terminal through the radio communication means to a center 30 for managing the key data and requests the return of key data 31. The center 30 confirms the sent terminal ID, selects the key data 31 corresponding to the contents of the terminal ID out of plural pieces of key data set to the center itself and returns these key data 31. The IC card terminal 10 holds the key data 31 received by the radio communication means into a RAM 3 and uses them at the time of communication with an IC card 20. When the supply of power to this RAM 3 is stopped, the held contents are erased. Namely, when the IC card terminal 10 is set in the standstill state, no card key is held in the terminal.

Title: Semiconductor electronic device
Inventor: MUKAI HISAKAZU
IPC: H01L23/522
Filed: 1978-05-29
Abstract: PURPOSE: To realize the miniature and high-performance circuit element by drawing out plural  number of electrodes close to each other through one small hole provided to the insulator film on  the surface of the semiconductor substrate and at the same time securing an automatic setting of  the inner region's position and the electrode's contact position via the hole edge.   
     CONSTITUTION: SiO 2 2 and poly Si electrode layer 3a are laminated on substrate 1 and the opening is drilled by etching in order to form the eaves part. Then poly Si3b is laminated to be left  only at the lower part of the eaves through the ion milling process. The oxidation is then given to  form a thick oxide film over Si3b, and then hydrofluoric acid treatment is given to form selectively SiO 2  film on film 3a and 3b by the difference of the etching speeds. Then the heat treatment is  given to form by diffusion p + -collector connection layer 14 from the electrode layer through part  of p-layer 6. Thus, layer 14 is formed over the entire circumference with automatic setting via the  opening and with an extremely small width with no use of the mask. The base diffusion with the  collector is possible with just one sheet of the mask and using film 5 used as the master. Thus, the  manufacture can be facilitated  with a miniature structure as well as reduced serial resistance  parasitic capacity.

Title: Magnetic recording and reproducing device
Inventor: TAKAHASHI MARIO
IPC: H04N9/83
Filed: 1988-03-18
Abstract: PURPOSE:To prevent deterioration in the quality of a picture and sound quality in case of opposite-phase reproduction by deciding whether the operation is of same phase reproduction or opposite-phase reproduction by using a phase difference signal of regenerating chrominance signals or regenerating luminance signals. CONSTITUTION:The burst gate circuit 100 of an automatic phase control circuit 10 takes out a burst signal component from a regenerating chrominance signal outputted from a comb-line filter 18 and inputs it to a phase comparator 101. The comparator 101 compares the burst signal with a reference signal outputted from a reference oscillator 102 to output a phase difference signal CER. A trap circuit 30 extracts a special-frequency component from the signal CER. This component is detected by a detector, and its output is compared with a decision voltage V1 in a comparator 33. When the detection output is equal to or larger than the decision voltage, a signal in H-level representing opposite- phase reproduction operation is outputted from the comparator 33, and the signal is outputted via an AND gate 34. Accordingly, when a decision output from the gate 34 represents the opposite-phase operation, a reproduced head is switched to an inverse-azimuth head to provided same phase operation.
