Title: Ink jet recorder
Inventor: FUKAZAWA HIDEO
IPC: B41J15/04
Filed: 1989-03-24
Abstract: PURPOSE:To effectively prevent a recording sheet from floating near a recording head with a simple and compact structure by providing recording sheet float preventing means longitudinally of the main scanning direction of the head. CONSTITUTION:A sheet retainer 19A disposed at the front side of a main scanning direction of a recording head 14, i..., at the downstream side of a recording direction at the time of recording is disposed in height for retaining substantially the center of a recording width, and a sheet retainer 19B disposed at the rear side of the main scanning direction of the head 14, i.e., at the upstream side of the recording direction at the recording time is disposed to press a position at the rear side of the sheet conveying direction of a recording width. The sheet retaining position is selected in this manner, thereby preventing the retainers 19A, 19B from rubbing with undried part of adhered ink to contaminate the sheet. Since a head guide 18 for composing float preventing means at the rear side of the sheet conveying direction of the head 14 is disposed in a state of the distance slightly longer than an ideal interval between the sheet and the head, it prevents the sheet from contaminating due to sheet floating such as cockling, etc., thereby maintaining recording quality.

The full count state of the counter 17 is maintained and at the same time a gain control clock is inputted to the counter 21 as a 2nd output C1. Then the amplification factor of the next amplifier is increased after the amplification factor of the first amplifier reaches its maximum level.

Title: Multi-stage amplifier
Inventor: FUNADA MASAHIKO
IPC: H03F3/68
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation in a frequency characteristic due to selection of a linear operation and a limiting operation and to reduce the cost by controlling bias voltage control of an amplifier and attenuation control of a variable attenuation in the same direction. SOLUTION: In a transistor amplifier circuit, linearity of the amplifier is increased because a saturation output power is increased as a bias voltage gets higher. Conversely, the saturation output power is reduced by decreasing the bias voltage, the output of the amplifier is saturated at a low input power and then the output power is constant. This characteristic is used to increase the attenuation of a variable attenuator 3 to increase the input power of the amplifier 5 and a bias voltage control circuit 7 is used to increase the bias voltage of the amplifier 5 to allow the multi-stage amplifier to conduct linear operation.  Conversely, the attenuation of the variable amplifier 3 is decreased to increase the input power of the amplifier 5 and the bias voltage control circuit 7 is used to reduce the bias voltage of the amplifier 5 so as to allow the multi-stage amplifier to conduct a limiting operation.

Filed: 1992-03-30
Abstract: PURPOSE:To make it possible to evaluate the measurement in the inside of a crystal, the measurement of the life of fluorescence, the wavelength dependence and the polarization dependence of the incident light by providing a laser light source, a projecting optical system, a filter and an analyzing device. CONSTITUTION:The laser beam having the wavelength of 800-1,500nm is projected into a crystal from the surface of a silicon crystal through a condenser lens 20. The lens 20 condenses the laser beam to the diameter of 3-20mum. The light, which is scattered in the crystal is focused through an image sensing element 21 through both lens 2 and 11. The image information, which is picked up with the image sensing element 21, is processed 22. The required information is sent into a control computer 8. A light polarizing element 25 is appropriately inserted into an optical path and turned so as to obtain the required polarized light state. Thus the polarization dependence of fluorescence, which is generated by obtaining the polarized state, can be investigated. An interference film is applied on the surface of a narrow-band transmitting film 23. When the angle between the filter surface and the optical axis is changed, the wavelength of the transmitting center can be changed. Therefore, the wavelength dependence on wavelength of the generating state of the fluorescence can be investigated.

Abstract: PURPOSE:To improve preliminary exposure operations by a method wherein a part of a semiconductor substrate is exposed preliminarily by using a mask and thereafter an overall exposure operation is conducted for the semiconductor substrate by using a mask, so that exposure pattern position setting can be implemented accurately even for one semiconductor substrate. CONSTITUTION:A position-matching check mark 102 alone is exposed in several semiconductor devices positioned in the peripheral part of a semiconductor substrate 101. In order to expose only a specified part of a specified semiconductor device, it suffices that step data to be exposed and an exposure blind area are modified in the case of a contracted-projection type exposure device, while it suffices that a part not used for a preliminary exposure operation is masked by a filter plate in the case of an exposure device of a contact type, a proximity type or the like. After the position setting of an exposure pattern is conducted accurately, an exposure operation is implemented for all semiconductor devices.
