Title: Revolution speed detection circuit
Inventor: IGAWA HARUO
IPC: G01P3/489
Filed: 1978-12-26
Abstract: PURPOSE: To easily detect the revolution speed of an electric motor or the like with high accuracy, by generating a voltage proportional to the time interval of light transmitted through the slits of a rotary member.  
     CONSTITUTION: Light from a light source 3 is detected by a sensor 4 through the  slits of a rotary plate 2 which is rotated by an electric motor 1. The detection output of the sensor is shaped. A signal for holding the value of a counter 10 is produced by the rising of the shaped signal. The counter 10 is preset by the falling of  the holding circuit. As a result, an input pulse from an oscillator 9 is counted by the counter 10 at every detection of the light by the sensor 4. The counted value is picked out through a D-A converter 12. Since the counted value is proportional to the rotational frequency of the motor 1, a voltage proportional to the rotational frequency can be produced if the output of a constant voltage circuit 15 and the output voltage of the D-A converter 12 are processed by an analogue division circuit 16.

Title: Preparation of semiconductor device
Inventor: SAITOU MANZOU
IPC: H01L21/768
Filed: 1983-09-07
Abstract: PURPOSE:To prevent an excessive etching of an applied film from deteriorating the shape with a level difference, by a method in which a first insulation film is perforated, applied with a solution and calcined to form a second insulation film, and the second film in the perforation is selectively removed. CONSTITUTION:An oxide film 25 is formed by means of vapor growth, and perforated beside the polysilicon electrode 23 to provide a contact hole 26. The substrate is rotationally applied with a solution of a compound containing silicon as its main element, and is calcined to form a film 27, which is then uniformly removed by etching. The film 27 applied within the contact hole is removed, using a photoresist. The photoresist 28 in the contact section is selectively developed and removed so that the photoresist 28 covers the side wall 26a of the contact hole 26 where a level difference exists. When the film 27 is removed by etching, the film 27 formed on the side wall 26a also can be removed. Since the film 25 has a lower etching rate than the film 27, the film 27b in the recess defined by the level difference is not removed by etching. Therefore, the effect of smoothing the level difference can be maintained.

Title: On-demand type ink jet head
Inventor: KONDO NORIMASA
IPC: B41J2/135
Filed: 1988-07-01
Abstract: PURPOSE:To enhance landing accuracy by stabilizing the speed and directionality of an ink particle by making the surface of the orifice on which is formed an ink film as small as possible. CONSTITUTION:The speed of an ink particles correlates with the size of an ink film 12 and, since the formation of the ink particle 13 becomes difficult as the ink film 12 becomes large, the speed of the ink particle becomes low. Since the forming range of the ink film 12 can be limited from a dimension (a) to a dimension (b) by allowing an orifice 7 to protrude, the speed range of the ink particle is determined. When the dimension (b) is taken small, the speed difference between ink particles can be reduced and the offset of the ink film 12 can be also prevented and, therefore, the flight direction of the ink particle 13 becomes stable. For example, when dimensions (a), (b), (c) and (d) are respectively set to 0.05mm, 0.15mm, 0.05mm and 0.05mm, the speed difference due to the difference of the ink film 12 is suppressed to 0.1m/S or less and it is extremely useful that the orifice is allowed to protrude.
