Patent JP-S6234006-A (JP)
Title: Apparatus for precisely measuring minute gap
Inventor: TANAKA YOSHITO
IPC: G11B7/22
Filed: 1985-08-07
Abstract: PURPOSE:To make it possible to measure a gap with high accuracy, by picking up an interference fringe as a stationary image. CONSTITUTION:The light emitted from a stroboscope light source 1 directs to an optical head 4 as light 3 through a lens 11 and a half mirror 2. A part of the light passed through the head 4 is reflected from the under surface of the head 4 to be converted to reflected light 3a and the remainder is reflected by the surface of a disc 5 to obtain reflected light 3b. Both reflected lights interfere to each other to generate the interference fringe corresponding to the gap between the head 4 and the disc 5. In order to photograph said interference fringe by a camera 6, the light 3 is adjusted by the lens 11 so as to be concentrated to the disc 5. In order to make the light emitted from the light source 1 synchronous to the rotation of the disc 5, a reference mark is applied to the disc 5 at one predetermined area thereof and detected by a sensor 7. By this method, the sensor 7 is adjusted so as to output a reference pulse 8 at every one rotation of the disc 5. This pulse 8 is delayed by a definite time by a delay circuit 9 and outputted to the light source 1 as a synchronous pulse 10 to allow the light source 1 to emit light. By this method, the photographing of a stationary state can be performed.

Title: Method for retrieving memory ticket
Inventor: KAZETANI KIYOSHI
IPC: H04M15/26
Filed: 1982-09-29
Abstract: PURPOSE:To extract a required memory ticket rapidly in accordance with an inquiry from a subscriber by using the duration of a call at the toll call as one means for the retrieval of the memory ticket. CONSTITUTION:An operator of a telephone exchange listens the telephone No. of originating and terminating subscribers and stores various information related to the connection of communication in a memory ticket assembling area TCM of a main memory MMc in a call processor. A main processor MPR transfers the TCM information to a division specified by a register RP of a pointer generating means PO in a completed memory ticket storing area TT. Originating and terminating subscriber's telephone Nos. in the TCM are transferred to key tables KA, KB respectively and the time corresponding to the call is stored from a 15min counter 15M CTR in a time information table TIMT. Thus a required memory ticket can be detected rapidly by using the information of KA, KB, TIMT as keys to retrieve the memory ticket.

Title: Current comparator
Inventor: NAITOU SEIICHI
IPC: G01R19/165
Filed: 1983-09-20
Abstract: PURPOSE:To measure a current or resistance with high accuracy, in a current comparator operated at an extremely cryogenic temp. using a SQUID fluxmeter, by continuously changing the inductance of an inductance coil connected to a pick-up coil in parallel. CONSTITUTION:Magnetic flux detected by the pick-up coil 6 of a cryostat CL filled with liquid helium is transmitted to an SQUID ring 8 through an input coil 7. The inductance of an inductance coil 71 connected to the coil 6 or 7 in parallel continuously changes when a super-conductor 72 is moved in an up-and-down direction. Therefore, even if magnetic flux generated from the coil 6 is constant, an SQUID signal proportional to said magnetic flux is outputted from an output terminal OUT. As a result, a constant current DC power source can be used and there is no influence of the change in Joule heat or the unstability of a power source and a current or resistance can be measured with high accuracy.

Title: System for controlling offset seek of magnetic disk device
Inventor: HASHIMOTO SHUICHI
IPC: G05B7/02
Filed: 1988-07-11
Abstract: PURPOSE:To reduce the offset seek processing time of a magnetic disk device without causing overshooting by calculating offset values reaching a target offset value stepwise as time elapses and increasing an offset voltage stepwise. CONSTITUTION:The control section 10 of a CPU 100 sets a target offset quantity for offset seeking in an offset calculating section 12 when ordinary seeking operations are completed. Upon receiving the setting of the target offset value, the calculating section 12 successively calculates an offset value which increases stepwise toward the target offset value as time elapses and outputs the offset value to an offset voltage generation circuit 14a. The circuit 14a generates an offset voltage corresponding to the offset value calculated by the section 12 and outputs the offset voltage to a position signal generation circuit 16. Therefore, the offset seeking speed of a head can be improved while the overshooting of the head is prevented.

Abstract: PURPOSE: To eliminate the need for a counter for changing-over of displays by detecting that an operating key was not operated for a fixed time after second zero setting, by the second counter of an electronic watch, and automatically changing over the mode to a time display mode.  
     CONSTITUTION: When the signal S 1  is inputted by key operation while the output of a conditional flip-flop 51 is in a second zero set state of C 1 =1, C 2 =0, an execution signal Z 1  for rounding-down for 23 and rounding-up for 24 is generated and a second counter is reset synchronously with the clock ϕ 1 . If the state of the second counter just before this is more than 24sec, a carry signal is introduced into a minute counter at the same instant of resetting of the second counter. When more than 24sec elapse after the key was operated, the signal output ZJ from a rounding decision signal generating circuit 52 assumes 1, and an AND gate G 5  outputs an automatic reset execution signal ARZ, by which the outputs C 1 , C 2  of the flip-flop 51 are reset at 00, and the mode returns to the time display mode.
