Title: Method for detecting erroneous injection of ink jet printer
Inventor: SAWADA KENJI
IPC: B41J2/175
Filed: 1987-02-13
Abstract: PURPOSE:To certainly detect an erroneous injection and to unnecessitate monitoring by a person, by catching the movement of the meniscus in the vicinity of a jet nozzle by an optical detector to indirectly detect whether an ink particle is normally injected. CONSTITUTION:When it is assumed that a recording head is normally operated, a piezoelectric element 6 is contracted when a voltage is applied to the piezoelectric element 6 from a drive circuit and a pressure chamber 4 is reduced in pressure and a meniscus 9 becomes a state drawn-in by 0.3-0.5 mm from the surface of a nozzle. At this time, since the ink blocking the light from a light source 8 disappears, the light reaches an optical detector 7. The meniscus vibrates in matching relation to the head and transmits or blocks the light from the light source with respect to the optical detector. As a result, the normal operation of the recording head is judged on the basis of the signal of the optical detector. When an injection malfunction is detected during printing, the recording head is moved to a purge position 17 present outside a recording section and the ink in the recording head is allowed to forcibly flow out by a purge mechanism 18.

Title: Recording and reproducing device
Inventor: WADA HAJIME
IPC: H04M11/10
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To conduct selective recording such that a confidential speech is not recorded by providing a control section or the like that controls each section of the title recording and reproducing device in a way that a DTMF code that is being recorded or has been recorded and audio data relating to the code are deleted from a recording and reproducing section. SOLUTION: A DTMF code outputted from a DTMF code detection section 103 is compared with a detection condition to delete a speech recording stored in a DTMF code detection condition comparison section 205. When the compared result denotes coincidence, the DTMF code detection condition comparison section 205 outputs a coincidence signal to a device control section 201 of a control section 2. Receiving the coincidence signal, the device control section 201 controls such that the device control section 201 interrupts recording when the device control section 201 is recording voice data, and deletes a recorded speech consisting only of index data or voice data from a recording section 5.

IPC: H01L21/8247
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent static damage of a second insulating film from being caused and moreover, to enable write and erase in a control gate(CG) voltage by a method wherein a plurality of grooves are formed in the surface of a floating gate(FG). SOLUTION: Three grooves 202 are formed in the surface of an FG 201 of a nonvolatile memory element. Therefore, the total extension of the lower parts of steps in the grooves 202, in which an electric field is easy to concentrate, in the surface of the FG 201 is increased as many as the number of the grooves 202. Accordingly, the degree of the concentration of the electric field in the low parts of the steps due to application of a voltage is relaxed in comparison with the degree of the concentration of an electric field in the lower parts of steps in grooves in the surface of a conventional FG with one recess part provided in the central part thereof. Moreover, in the case where each roundness is given to the square parts extending from the bottoms of the grooves 202 to the sidewalls of the grooves 202, the degree of the concentration of the electric field is further relaxed. Furthermore, as the opposed area between the FG-CG of the memory element is made wider than the opposed area between the FG-CG of a nonvolatile memory element having the conventional FG, a CG voltage V CG for obtaining a prescribed FG voltage FG is further reduced. Accordingly, the static damage of a second insulating film 106 between the CG-FG can be prevent from being caused.
