Title: Multistage speed change gear apparatus with auxiliary speed change gear
Inventor: MAEDA FUJIO
IPC: F16H3/66
Filed: 1991-08-27
Abstract: PURPOSE:To provide a speed change gear apparatus capable of effecting always- optimum speed reduction ratio power transmission in corresponding relation to a wide variety of changes in the slope of the running road as well as in the load conditions applied to the vehicle. CONSTITUTION:An auxiliary speed gear unit 30 composed of a planetary gear 30 equipped clutch 31 and a direct coupled clutch 34 is connected to a planetary gear type speed change gear apparatus. The speed reduction ratio beta of the planetary gear 30 is set, with respect to the inter-stage ratio between each speed stage in the planetary gear type speed change gear apparatus 10, to a range of beta alpha2.5/2 to alpha3.5/2. By this, a new tractive force curve is added to the boundary portion of each speed-stage tractive force curve of the planetary gear type speed change gear apparatus 10 as a base. Accordingly, very narrow inter-stage ratios and a very wide whole inter-stage ratio are obtained with the result that even in a working field where high-load/large-slope road surfaces and low-load/small-slope road surfaces coexist, the apparatus can be operated at an optimum speed reduction ratio, thereby realizing reduction in the fuel consumption rate as well as enhancement in the working efficiency.

Filed: 1984-11-15
Abstract: PURPOSE:To eliminate the delay time for production of a waiting signal by attaining the control of the memory cycle length within a processor when accesses are given to external memories having different speeds in response to each address space. CONSTITUTION:The external memories 101-103 having different speeds in response to each address space are connected to an address bus 104 and a data bus 105 of a microprocessor (MPU) 100.

Title: Synchronizing pattern generating method
Inventor: IIZUKA HIROYUKI
IPC: H04L7/04
Filed: 1983-12-20
Abstract: PURPOSE:To obtain the high capacity for detection of a synchronizing pattern by setting a different data word at the position where the same data word is set to obtain a synchronizing pattern. CONSTITUTION:When a data word train containing synchronizing patterns D and D' is supplied to a coder 2, a data word train 9 containing an error is delivered to the reception side of data from a decoder 8 together with a signal 10 showing the presence or absence of an error of the data. While the same data of each channel are transmitted twice and it is avoided that only patterns D and D' arrive at the place where the same data should be received. Therefore the pattern D is detected at the reception side and the different 32-bit data D' is received. At the same time, it is confirmed that the pattern D' contains no error. Then a synchronizing pattern is defined.

Title: Signal detecting circuit
Inventor: MIYOKAWA ATSUSHI
IPC: G11B15/087
Filed: 1989-09-18
Abstract: PURPOSE:To prevent the influence of noise and to make operation exact for selecting a piece of music by measuring time for the output signal of a peak level holding circuit to be lowered from a peak level to a detection level, and deciding the output signal as a signal when the measured time is longer than set time. CONSTITUTION:In the state of the operation for selecting the piece of music, a reproducing signal to be inputted from a peak level magnetic head 1 to a peak level holding circuit 15 is lowered from the peak level to the bottom detection level, which is detected by a control circuit 10, according to the characteristic. Time T is measured by a time measuring circuit 19 and the time is compared with the time set by a time setting circuit 18. When the time T is shorter, the circuit 10 judges the absence of an input signal and when the state passes prescribed time, a non-signal part between the pieces of music is judged. Then, the operation is switched from the state of the operation for selecting the pieces of music to a reproducing state. Thus, the influence of a noise signal is eliminated and the operation can be exactly executed for selecting the piece of music.

Title: Magnetic head
Inventor: MUTO KAZUTOSHI
IPC: G11B5/127
Filed: 1993-09-28
Abstract: PURPOSE:To prevent the pseudo output and sliding noise of the magnetic head consisting of a pair of core half bodies and butted ferromagnetic alloys of a 'SENDUSTR' compsn. formed on the butt surfaces of the respective core half bodies by forming the core half bodies of a single crystal ferrite exhibiting fine magnetism. CONSTITUTION:The core half bodies 21, 22 exhibiting slight magnetism by properly heat treating the single crystal ferrite are prepd. The ferromagnetic alloy films 23, 24 of the 'SENDUSTR' compsn. are formed on the butt surfaces 25, 26. The films 23, 24 are thin films of a single layer. The films 23, 24 are butted against each other via a gap material to form a magnetic gap 28. Low melting glass 29 is packed into a track width regulating groove. Windings 30, 31 are across the core half bodies and the ferromagnetic alloy films but the core half bodies are equal to the nonmagnetic substrate and, therefore, the magnetic fluxes do not flow to the core half bodies. The pseudo gap is not formed in the boundary parts between the core half bodies and the ferromagnetic alloy films and the pseudo output is not formed therein. Since the core half bodies forming the head surface 42 is equal to the nonmagnetic substrate, the sliding noise is drastically suppressed.
