Publication number: 20120075510Abstract: The present invention enables switching between bright-light shooting and low-light shooting with an infrared cut filter placed on an optical path. An optical system captures and focuses image light from a subject. The focused image light passes through a multilayer infrared cut filter placed on an optical path of the image light and forms an image on an imaging device. The imaging device has sensitivity to at least the visible to near-infrared region. The infrared cut filter is constructed by forming a multilayer dielectric film on a surface of a transparent substrate. The infrared cut filter has a cutoff wavelength near a boundary between the visible region and near-infrared region and is configured so as to have a high incident-angle dependence. An angle of the infrared cut filter with respect to an optical axis of the optical system is varied by an incident angle varying mechanism according to an amount of light on the subject, shifting the cutoff wavelength.Type: ApplicationFiled: June 28, 2011Publication date: March 29, 2012Applicant: MURAKAMI CORPORATIONInventors: Hidenori SATO, Yoshiyuki TERADA

Publication number: 20100188737Abstract: To provide a dielectric multilayer filter, such as an IR cut filter and a red-reflective dichroic filter, that produces an effect of reducing incident-angle dependency and has a wide reflection band. A first dielectric multilayer film 30 is formed on the front surface of a transparent substrate 28, and a second dielectric multilayer film 32 is formed on the back surface of the transparent substrate 28. The width W1 of the reflection band of the first dielectric multilayer film 30 is set narrower than the width W2 of the reflection band of the second dielectric multilayer film 32. The half-value wavelength E2L of the shorter-wavelength-side edge of the reflection band of the second dielectric multilayer film 32 is set between the half-value wavelength E1L at the shorter-wavelength-side edge and the half-value wavelength E1H at the longer-wavelength-side edge of the reflection band of the first dielectric multilayer film 30.Type: ApplicationFiled: March 8, 2010Publication date: July 29, 2010Applicant: MURAKAMI CORPORATIONInventor: Yoshiyuki Terada

A dielectric multilayer film 30 is formed on a front surface of a transparent substrate 28 to form a dielectric multilayer filter 26. The dielectric multilayer film 30 is composed of films 34 of a intermediate-refractive-index material and films 36 of a high-refractive-index material alternately stacked one on another. The intermediate-refractive-index material forming the films 34 has a refractive index higher than 1.52 and equal to or lower than 2.1. The high-refractive-index material forming the films 36 has a refractive index equal to or higher than 2.0 and higher than the refractive index of the intermediate-refractive-index material forming the films 34.Type: ApplicationFiled: May 14, 2007Publication date: January 17, 2008Applicant: MURAKAMI CORPORATIONInventor: Yoshiyuki Terada

Patent number: 6950221Abstract: An electrically conductive metallic clip used for lead-out electrodes of an EC mirror has all-shaped section. One of an opposed side pieces of the clip is disposed at the side of an electrically conductive film and is formed in a planar shape. The other side piece disposed at the side of a glass substrate is configured in a curved shape and has a terminal that is outwardly round-opened. A central portion of the other side piece is formed in a convex shape so that an opening thereof is narrowed. When a sealing resin expands, an occurrence of poor contact between a lead-out electrode portion and the clip is prevented. Moreover, good workability for attaching the clip to the substrate is realized. Furthermore, the lead-out electrode is prevented from being damaged. Additionally, the clip is prevented from being deformed when the clip is fitted onto the substrate.Type: GrantFiled: May 21, 2001Date of Patent: September 27, 2005Assignee: Murakami CorporationInventors: Yoshiyuki Terada, Takuo Mochizuka

Patent number: 6829074Abstract: A liquid type electrochromio (EC) element is configured by substrates having tapping electrode portions as a part of a unified substrate by the processing of the substrate. When the upper and lower tapping electrode portions are provided on one side such that they are not piled up with each other, the ratio of the effective area can be increased and the area for covering the tapping electrode portions can be decreased in comparison with the technique in which the upper substrates are shifted with each other. Also, since the areas of the tapping electrode portion can be decreased in comparison with the technique in which the upper substrates are shifted with each other, the weight of the EC element can be decreased. Also, the weight can be decreased by dividing the tapping electrode portion into two tapping electrode portions each having such size that one is not piled up with another.Type: GrantFiled: October 22, 2003Date of Patent: December 7, 2004Assignee: Murakami CorporationInventors: Yoshiyuki Terada, Takuo Mochizuka
