Title: Speed-change device of auxiliary transmission
Inventor: OKAHARA HIROBUMI
IPC: F16H61/06
Filed: 1989-05-18
Abstract: PURPOSE:To prevent interlock by holding a shift valve in the hydraulically operated state of its low-speed selecting frictional element by the outputted reverse selection pressure, in the reverse traveling range (reverse rotation output) position of the manual valve of a multiple stage automatic transmission. CONSTITUTION:When a manual valve is operated to R range, a reverse selection pressure PR is led into the chamber 48d of a third shift valve 46 through a one-way orifice and shuttle valve to move a spool 46b upward, thus disengaging the connection of a frictional element D/C for high-speed selection and applying a line pressure PL to a friction element RD/B for low-speed selection to connect it. With this constitution, even if an auxiliary transmission is mis-operation by a computer, the friction element D/C will not be operated. Accordingly, such a danger as the friction element D/C is driven in reverse traveling range (in reverse rotating output) and the auxiliary transmission is interlocked with the D/C and a one-way clutch in parallel with the friction element RD/B can be prevented securely.

Abstract: PURPOSE:To make high-speed printing possible by eliminating a part of the continuous dots of fundamental dot pattern after extracting the continuous dots. CONSTITUTION:When data from a host computer is received by CPU20 and the received data are character codes, the character codes are converted into dot matrix-shaped printing pattern data, the maximum value of the number of columns of the printing pattern data for one character is set, e.g. the higher, middle and lower bit data groups of one byte in the Xth column of the printing pattern data are inputted successively and respective groups are written in the Ax, Bx and Cx addresses of the storage areas A, B and C of an image buffer 24.

IPC: H04R1/02
Filed: 1990-05-14
Abstract: PURPOSE:To simplify the constitution of a vibration preventing device of a microphone unit by allowing a case side equivalent to a grip to eliminate external vibration. CONSTITUTION:A case 1 equivalent to a grip is divided into an inner case 1a and an outer case 1b. The both have a high internal loss and are made of a material with a different natural frequency to propagate the vibration, a soft material is used for the outer case 1b to provide a buffer effect against a chock thereby suppressing the resonance of the inner case 1a. Thus, external vibration is suppressed and the case 1 itself eliminates the vibration noise without complicated support mechanism off the microphone unit 4. Thus, the occurrence of vibration noise is prevented with a simple constitution.

IPC: H01J29/54
Filed: 1979-09-28
Abstract: PURPOSE:To allow a permanent magnet not to be affected by temperature change, by uniting the permanent magnet for alignment correction with a magnetic adjuster steel. CONSTITUTION:To an annular permanent magnet 20 a magnetic adjuster steel 22 is combined and fixed. Here because a magnetic shunt circuit is produced by a reason of mounting the magnetic adjuster steel 22, size of the permanent magnet 20 must be enlarged. Selection of the size can be determined by how much a change of temperature is expected. For instance, when the change of temperature is expected 40 deg.C, if assumed -0.2%/ deg.C for temperature coefficient of a ferrite magnet and maximum 5 gauss for requirement of the magnetic field, the magnetic field is changed 0.4 gauss for the change of 40 deg.C. When this change is corrected, appropriate  selection of the kind of the magnetic adjuster steel 22 can determine the size in thickness from designing data.
