Filed: 1985-11-21
Abstract: PURPOSE:To improve the environmental resistance of a head by pressing a front core comprising the magnetic recording medium sliding face side part of a magnetic circuit in a magnetic head with an elastic member from a sliding face side and contacting with pressure a back core comprising the remaining part of the magnetic circuit so as to joint both cores. CONSTITUTION:The front core 1, the back core 2 and a bobbin 3 are constituted the same as popular ones. However, a difference is that a flat spring 5 for contacting with pressure and fixing the cores 1 and 2 presses the magnetic tape sliding face 1a of the front core 1. Accordingly the shape of the flat spring 5 is not limited by the terminals 8 and 8 of the bobbin 3, thereby improving the degree of freedom is designing. The flat spring 5 is formed in a rectangular frame body, and its upper and lower frame pars 5a and 5c are formed at a lower curvature than that of the magnetic tape sliding face 1a bending cylindrically, while its left and right frame parts 5b and 5d are bent approximately perpendicular with respect to the upper and lower frame parts 5b and 5c.

Abstract: PURPOSE:To improve the comfortableness to ride by detecting vertical accelerations at multiple positions of a vehicle body, judging whether the vertical acceleration is normal or not, and controlling an active type suspension using a value subtracted with the average Value of vertical accelerations from the measured value when it is normal. CONSTITUTION:Vertical acceleration detecting means are provided at multiple positions of a vehicle body, end their outputs are inputted to a judging means. The judging means judges whether the vehicle body is in a normal vertical acceleration generating state or not, if it judges that the vehicle body is in a normal vertical acceleration generating state, the average value of vertical accelerations is calculated, and the average value is outputted to a correcting means. The correcting means subtracts the average value from the detected vertical acceleration. Thereby, the normal vertical acceleration is removed, and the corrected vertical acceleration is obtained and outputted to a command value calculating means. The command value calculating means determines the command value for an active type suspension based on this corrected value and controls it. According to this constitution, the comfortableness to ride is improved.

Title: Transistor circuit
Inventor: OTSUKA YASUHIRO
IPC: H03K19/013
Filed: 1987-10-15
Abstract: PURPOSE:To shorten the rise time and the fall time of an output waveform by discharging in a short time the charge which has been charged to the parasitic capacity of a transistor by a constant-current source. CONSTITUTION:When an input terminal 1 is in a low potential, the collector potential of a transistor 6 rises, therefore, the base potential of a transistor 7 rises and the emitter potential rises. On the other hand, the emitter potential of a transistor 8 drops. A charge which has been charged to the parasitic capacity between a base and a collector of a transistor 9 is discharged by a constant- current source 14 which has been connected to the base of the transistor 9, therefore, the discharge time is short. Accordingly, the time when the collector potential of the transistor 9 reaches a high potential is also shortened. Therefore, the rise time of a voltage which appears in an output terminal 15 is shortened. Also, when the input terminal 1 is in a high potential, the fall time of a voltage which appears in the output terminal 15 is shortened.

Abstract: PURPOSE:To make measurement with the higher sensitivity by absorbing intermitted light in a sample so that an optoacoustic signal is generated in a cell. CONSTITUTION:A cellulose film conjugated with an anti-human antibody HCG is adsorbed to a reaction solid phase disk of a porous material set on a holder and thereafter, this holder is imposed on a reaction device 21. A serum sample is added by a sample pipetter 36 onto this disk and after 5 minutes, an anti- human antibody HCG soln. labeled with FITC is added thereto. The excess moisture is absorbed into a porous material. Further, a tris-hydrochloric acid buffer soln. is added thereto after standing for 5 minutes at room temp., by which the unreacted excess FITC-labeled anti-human antibody HCG soln. and moisture are absorbed in the porous material and are removed from the cellulose film surface. The antigen-antibody reaction conjugate is thus formed on the cellulose film. The reaction solid phase in the device 21 is then transferred by a reaction solid phase transfer device 20 into an optoacoustic cell 23 and a cap is put thereon to hermetically close the cell. The laser light from a light source 17 is made incident into the cell 23 and the optoacoustic signal based on the antigen-antibody reaction conjugate is measured.
