Inventor: MIYAGAWA AKIKO
IPC: G02B1/10
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To produce the subject molded product capable of recovering once deteriorated antifogging performances and exhibiting excellent antifogging performances for a long period by forming a hydrophilic thin film layer having the antifogging performances on a substrate and then irradiating the resultant layer with ultraviolet rays at a short wavelength. SOLUTION: A hydrophilic thin film layer having antifogging performances is formed on a substrate and the resultant layer is then irradiated with ultraviolet rays at a short wavelength of <=300 nm to thereby produce a molded product having the antifogging performances. The antifogging performances of the hydrophilic thin film layer irradiated with the ultraviolet rays are preferably deteriorated. The hydrophilic thin film layer is preferably formed by using a sputtering method comprising a step for sticking metal atoms onto the substrate and a step for oxidizing the metal sticking thereto, forming an oxide and forming the hydrophilic thin film layer. Furthermore, an ultraviolet absorbing layer is preferably provided between the hydrophilic thin film layer and the substrate in order to avoid the discoloration, etc., of the substrate with the ultraviolet rays.

Title: Power-on reset signal generating circuit
Inventor: KURAYAMA TAKAYUKI
IPC: H03K17/22
Filed: 1987-04-23
Abstract: PURPOSE:To decrease power consumption by providing a transistor (TR) connecting in series with a (TR) being a component of a reset pulse width control circuit and executing switching operation by a generated reset signal so as to reduce the steady-state current after reset. CONSTITUTION:At application of power via a capacitor 5, the level of an input of an inverter 7 rises nearly equal to a power voltage, resulting that the output Q1 rises and reaches a high level. Then an N-channel TR 9 is turned on. When the power voltage exceeds a threshold value of an N-channel TR 2, the TR 2 is turned on and a gate input of a P-channel TR 1 goes to a low level and the TR 1 is turned on. In this case, a voltage proportional to the on-resistance of the TRs 1, 2 exceeds the threshold value of the N-channel TR 4, then the TR 4 is turned on and the input of the inverter 7 goes to a low level and the output Q2 goes to a low level. Then the N-channel TR 9 is inverted to be in the OFF state to interrupt the current flowing to the TRs 1, 2.

Title: Electron beam crystal growth method
Inventor: WADA TAKAO
IPC: H01J37/30
Filed: 1987-04-24
Abstract: PURPOSE:To realize low-temperature solid-phase epitaxy with few defects, by radiating high energy electron beams on a surface of a thin film on a semiconductor substrate so as to obtain epitaxy of a compound or a mixed crystal semiconductor which is a constitutional element of the substrate and thin film. CONSTITUTION:Electron beams 3 are taken out from an electron accelerator 1 through a takeout window 2, and these accelerated electron beams 3 are radiated onto a surface of a thin film 5 on a semiconductor substrate 4. Energy of the electron beams 3 taken out from the accelerator 1 needs to be large enough to spring out atoms at the lowest, and it is generally preferable that this energy is in the degree of 1MeV to 2Mev or more. This radiation process is allowed to be performed in the air; however, it should be preferably performed during the flowing of an inactive gas or in an vacuum atmosphere in the case of the substrate which requires oxidation-proofing or the thin film. Hence, any mixed crystal can be easily formed on arbitrary positions by the above method.

Abstract: PROBLEM TO BE SOLVED: To realize a compact, lightweight, low-cost equipment by comparing an input signal waveform to a high-voltage AC output waveform, performing the power amplification based on the result of the comparison, applying it to a contact charging device to stably maintain a charged potential, and achieving a high-quality image. SOLUTION: A result of voltage division of an AC high-voltage output waveform is directly compared to an input waveform signal 6 by comparing a means 4. Then, based on the result, an error is amplified by a comparator U3, and an AC high-voltage output is generated through a power amplifier 1 and a booster transformer T1. Because of this, by the current waveform of a distorted waveform occurred in a rectifying circuit, the distortion of an AC high-voltage output waveform occurring in a leakage inductance of the booster transformer T1 is corrected by the error-amplifying operation, and the AC high-voltage output waveform which is always synchronous with the input waveform signal can be obtained. Thus, by applying it to the contact charging device, high-quality images with a charged voltage which is maintained stable can be achieved realizing compactness, light-weight and low cost.
