Title: Disk cache device
Inventor: YAO TORU
IPC: G06F12/06
Filed: 1992-02-13
Abstract: PURPOSE:To keep a high cache hit rate by dividing blocks in a disk device and a cache memory into sets and mapping them in the same set. CONSTITUTION:Each time read or write is requested to a disk device 4000 within a prescribed time, an access frequency detecting circuit 3400 reads the volume number from an address register 3300 and counts the frequency in access to each logical volume and sends the counted result to a disk cache control circuit. A set address generating circuit 3500 internally has a volume-set correspondence table 3510 and takes a logical volume number 3310 of the disk device 4000 as the input and refers to the volume-set correspondence table 3510 to generate a set address. Normally, respective logical volumes of a cache memory 3200 and those of the disk device 4000 correspond to each other in 1:1, but contents of the volume-set correspondence table 3510 are changed by information of the access frequency detecting circuit 3400.

Title: Non-volatile semiconductor memory
Inventor: ICHIKAWA MAKI
IPC: G11C16/06
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a non-volatile semiconductor memory that a leak current is not made to flow in a boosting circuit even if a pad for test is separated after finish of the test. SOLUTION: This non-volatile semiconductor memory is provided with a boosting circuit 2 generating boosting voltage Vr, a control circuit 3 controlling the boosting circuit 2, and a comparator 4. At the time of a test mode, the comparator 4 performs feedback control so that boosting voltage is equalized to test voltage supplied to a test voltage pad. Thereby, boosting voltage can be controlled surely externally. In normal operation, the control circuit 3 supplies an inversion signal of a clock signal to a boosting circuit. Therefore, a leak current is not made to flow in a boosting circuit even if a test voltage pad is cut off after finish of a test.

Abstract: PURPOSE:To suppress transmission error and to improve transmission efficiency by using a radio equipment varying a transmission output in multi-stage and setting a transmission output level of a transmitter prior to the start of a transmission procedure so as to make the reception level of the receiver to a prescribed value or over. CONSTITUTION:While a transmission output level of a transmission section 12 is set to a minimum value, a facsimile control section 1 of a transmitter outputs a tone signal from a tone generating circuit 9 and sends it to a receiver as a level discrimination signal LVC1. When the reception level is smaller than a threshold value, while the transmission output level of the transmission section 2 is set to a value larger by one stage from the minimum value, the reception level being a smaller value than the prescribed value is replied to the transmitter. The transmitter resets the transmission output level of the transmission section 12 to a larger value and the tone generating circuit 9 outputs a tone signal and sends it to the receiver as a level discrimination signal LVC2, the level is set repetitively till the value is replied to be a reception level specified value.

Filed: 1989-02-06
Abstract: PURPOSE:To obtain IC-VBE characteristics not presenting negative resistance by providing a resonance tunnel having a well with a specified thickness while forming the interface so as to have a low degree of flatness on the level of atomic layer. CONSTITUTION:An emitter barrier layer 6 is formed between a base layer 5a and an emitter layer 7, and a resonance tunnel is provided in the emitter barrier layer 6. The resonance tunnel has a well with a thickness of 20-35Angstrom . During growth of the well, temperature of a semi-insulative substrate 1 is held low at about 400 deg.C so that flatness of the interface on the level of atomic layer becomes of a low degree. If the well is narrower than 20Angstrom , it will not function as a quantum well. If it is wider than 35Angstrom , negative resistance will be presented. According to this arrangement, IC-VBE characteristics not presenting negative resistance can be obtained while a resonance tunnel structure is used, namely, while a current density is kept high.

IPC: G11B7/09
Filed: 1983-02-21
Abstract: PURPOSE:To prevent a spot from being moved to another bit train by the influence of noise, external impact, or the like, by extending practically a control area of a tracking error control signal to an optional bit train. CONSTITUTION:When the spot is moved to the outside of a line l2 in the figure, a phase comparator 20 outputs a phase difference signal D because the outside of the line l2 is the control area to a bit train (N+1); but since this phase difference signal D is supplied to a non-inverted input terminal (+) of an operational amplifier 31 through an AND circuit 25, an OR circuit 27, and a low pass filter 29, a positive-polarity tracking error control signal shown by a solid line B is attained. When the spot is moved to the inside of a line l1, the tracking error control area is extended practically by components indicated by solid lines B and D similarly, that is, a hysteresis characteristic is given to the tracking error control signal; and thus, the spot is prevented from being moved to another track by noise, external impact, or the like.

Abstract: PURPOSE:To stabilize the carrying speed of a portable medium and to attain accurate reading by arranging a 2nd carrying means in the vicinity of an insertion port independently of a 1st carrying means, and when carrying is to be executed prior to carrying operation based upon the 2nd carrying means, executing the idle running of the 2nd carrying device. CONSTITUTION:When a magnetic card 3 is inserted from an insertion port 5 into a guide case 1, the card 3 is interposed between a driving roll 39 to be the 2nd carrying means and an idle roll 41 and carried to the magnetic head 15 side. When the card 3 reaches between the driving roll 9 and an idle roll 11 at constant speed, the card 3 is carried by the driving force of the roll 9 and a magnetic head 15 reads out information on a magnetic stripe 13. Since the diameter of the roll 9 is slightly larger than that of the roll 39, the card 3 is carried at speed slightly faster than the carrying speed of the roll 39, a clutch pulley 45 is applied to the roll 39 at that time and the roll 39 is turned to an idle running state, so that stable reading can be attained.
