Title: Electric-charge pump operated by low- voltage power supply
Inventor: EI KAARU RATSUPU
IPC: H02M3/07
Filed: 1993-10-04
Abstract: PURPOSE: To obtain a charge pump for efficiently generating a high voltage necessary to a non-volatile memory from a low voltage power source, which is not unreasonably resistive, not power consuming or not large in physical size. CONSTITUTION: A charge pump 40 for increasing the amplitude of a power supply voltage signal Vcc includes an auxiliary pump 42, buffer stage 44, and main pump 46. The auxiliary pump generates several intermediate voltage signals in response to a pair of complementary clock signals ϕ1 and ϕ2 . Each intermediate voltage signal has different amplitudes, and they are larger than the amplitude of the power supply voltage signal. A buffer stage increase the amplitudes of the pair of complementary clock signals in response to the several intermediate voltage signals generated by the auxiliary pump. A main pump increases the amplitude of the power supply voltage signal in response to a pair of auxiliary clock signals ϕ1 <+> and ϕ2 <+> whose amplitudes are increased generated by the buffer stage.

Title: Production of thin film magnetic head
Inventor: TSUJINO FUMI
IPC: G11B5/31
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To form an upper magnetic core having a precise track shape by separately plating a frame in a track part and plating a frame in other part of the upper magnetic core. SOLUTION: A resist is applied in such a manner that the resist is preferentially made thick only in the track part than the desired thickness but the resist is made as thin as possible. Then a photomask is overlapped on the resist film thus formed. The resist film is exposed by irradiation of light through the photomask. Exposure is preferentially preformed only the track part and the light intensity for exposure is determined so that the resist in the track part causes enough reaction with light but not cause overexposure. Thereby, the photoresist not covered with the photomask is made soluble while only the photoresist 14 covered with the mask forms a frame according to the photomask pattern. Thus, the part except for the track part remains to cover the plate base coating layer.

Inventor: IHARAKI MASAHIRO
IPC: G10L13/07
Filed: 1991-09-26
Abstract: PURPOSE:To suppress the spurious high frequency when a basic waveform is read out and an optional waveform is generated by deciding the window width so as to secure the smoothness approximate to the basic waveform for the waveform which is generated with the interpolation carried out in a set window by a spline function.
