Patent JP-H03284968-A (JP)
Title: Thermal printer
Inventor: NAKAMURA MASAYA
IPC: B41J25/312
Filed: 1990-03-30
Abstract: PURPOSE:To make it possible to generate a large pressing force beyond the level of a traction force which pulls a pressing lever by mounting axially the one ends of two levers on a thermal head and the frame of a thermal head pressing mechanism in freely rotatable manner, and the other ends of the levers axially in such a manner that these ends rotate with each other, and attaching a traction spring connected to a traction device near the part where the levers are axially mounted. CONSTITUTION:If a cam 6 rotates in 't1' direction and indicates a change from position A to position B, an L lever 5 is activated to lift a thermal head 2 so that the latter is allowed to come close to a platen 1. At the same time, a triangular lever 10 is activated to cause traction of a traction lever 13. If the cam 6 arrives at the position B, the thermal head 2 goes further upward to be slightly pressed against the platen 1, and at the same time, a lever 8 and a layer 9 are open in a sectoral shape. In addition, if the cam 6 reaches position C, the triangular lever 10 acts in such a manner that it pulls the traction lever 13 additionally, although the L lever 5 does not change. Subsequently, the traction lever 15 pulls a traction spring 16 more strongly. Thus the lever 8 and lever 9 push the thermal head 2 further upward by a strong force beyond the level of a traction force according to a principle of leverage and thereby the platen 1 is strongly pressed.

Title: Encryption processing method in encryption communication system
Inventor: KOBAYASHI MICHIO
IPC: H04L9/08
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To realize low cost by simplifying a circuit realizing an encryption compensation system adopting the KPS system. SOLUTION: Identification information specific to two respective communication units is mutually exchanged, a value R2 is obtained as an execution ID of the exchanged opposite unit by using a unidirectional function (h) from the identification information of the opposite party of exchange and an encryption algorithm is used to encrypt transmitted information as the unidirectional function (h) when a common key is generated by the execution ID (R2) and a security algorithm X1 generated specific to a concerned unit. Furthermore, after the end of arithmetic processing by the secret algorithm X1, a common key can be generated through conversion processing by using another unidirectional function (g). In this case, the encryption algorithm encrypting the information to be sent is used in place of the unidirectional function (g) for generation of the common key.  Moreover, in this case, the encryption key is changed by respective unidirectional function.

Title: Detection system for position of moving body using inductive radio
Inventor: IMAI MITSUO
IPC: B61L3/12
Filed: 1980-06-26
Abstract: PURPOSE:To achieve accurate position detection at a moving body side by receiving information on the absolute address position of the moving body, detected on the ground, by the moving body, and then by correcting it corresponding to continuous detection information on the position of the moving body at the moving body side. CONSTITUTION:The absolute address of a moving body is detected by a ground- side device 50 through an inductive ratio line 10 for absolute address detection, and then transmitted by a data transmission controller 53 and a data signal transmitter 54 through inductive radio line 30 for absolute address position information transmission. Then, it is received by a position information receiver 31 at the moving body side and the pitch of a continuous position detector 21 is corrected by a correcting circuit 41 according to continuous detection information at the moving body side through an inductive radio line 20 for continuous position detection which corresponds to every absolute address. Consequently, an error due to the delay of the reception of the absolute address signal detected on the ground side is corrected, so that accurate position detection at the moving body side is achieved.

Title: Ultrasonic linear motor
Inventor: KOGO MASANORI
IPC: H02N2/00
Filed: 1990-04-03
Abstract: PURPOSE:To simplify a driving circuit by securing one end of a telescoping piezoelectric element to a fixed base and mounting a frictional member on the other end, bringing a mover movable in parallel with the telescopic motion into pressure contact with the frictional member, and applying a saw-tooth voltage onto the piezoelectric element. CONSTITUTION:A telescopic piezoelectric element 1 has one end secured to a fixed base 2 and the other end mounted with a frictional member 3 extending laterally over the piezoelectric element 1, and the telescopic motion of the piezoelectric element 1 causes telescopic motion of the frictional member 3. A mover 4 movable in parallel with the telescoping direction of the piezoelectric element 1 is brought into pressure contact with the frictional member 3. Upon application of a saw-tooth voltage onto the piezoelectric element 1, for example, higher frictional force is produced when the piezoelectric element contracts as compared when the piezoelectric element 1 elongates and thereby the mover 4 moves in the contracting direction of the piezoelectric element 1. Consequently, only telescopic motion is required for the piezoelectric element 1 which produces a driving force.

Title: Disk rotor
Inventor: MUNAKATA MORITOSHI
IPC: G11B19/20
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To drastically increase a frictional force, to set a rotational speed to a high level and to shorten an accessing time by coating a frictional surface with paint having a high friction coefficient. SOLUTION: This disk rotor is formed of a frictional surface 1 for mounting a recording tool and a recessed section 2 slightly recessed therefrom. This frictional surface 1 is coated with urethane resin paint having a high friction coefficient by removing the inner circular guide section 3 of the disk rotor (so as to have a film thickness of 10 to 35μm). Thus, a painted film surface made to be smooth, a disk cushioning effect is provided, a frictional force is increased and disk rotation accurately follow the change of the rotation of the disk rotor. Accordingly, even when a pressing force to the disk rotor is small, the disk is similarly used without slipping. Thus, the rotational speed of the disk rotor is set to a higher level for performing a skip operation such as fast-forwarding, fast-rewinding or random performance and an accessing time is shortened.  Also, since coating is simple, the number of working steps is reduced.

Abstract: PURPOSE:To shorten a period from the occurrence of a fault to the detection of the fault by setting a test signal time slot in a radio frame, and transmitting a burst signal for test with the test signal time slot in the radio frame by a slave station. CONSTITUTION:A polling time slot and the test signal time slot are set on the radio frame, and the reception station of an up line i.e., a master station 1 or a relay station 22 controls the transmission operation of the burst signal for test at the time position of the test signal time slot for the slave station.

Title: X-ray analyzing apparatus

IPC: G01N23/225
Filed: 1983-05-20
Abstract: PURPOSE:To measure the peak strength excluding a background component in a short time, by multiplying a counted value at a wavelength in the vicinity of a wavelength selected by a spectroscope by a specified ratio, and subtracting the resultant value from the counted value of the detected pulses of an X-ray detector. CONSTITUTION:An X ray having a wavelength lambdao is selectively detected by an X-ray detector 8. Pulses are counted only during a time T. The X-rays generated from a sample 6 are simultaneously detected by a semiconductor detector 14 and counted at every energy region. An electronic computer 12 obtains a measured value Be' of a background expressed by the expression in the Figure from a wavelength-dispersed type X-ray spectroscope, based on the stored value. A counted ratio (f) and a counted time T at this time are multiplied. Thus, Bw= Be'fT, which is a background measured value converted by the wavelength-dispersed type X-ray spectroscope, is counted. By using the counted value N(lambdao), N(lambdao)-Be'fT is computed. The result is the peak strength excluding the background component at the wavelength lambdao.
