Title: Image recorder
Inventor: TANIHATA TORU
IPC: G02F1/055
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To reduce time and labor required for positioning in the focusing direction of a sensor and to appropriately and surely perform such positioning. SOLUTION: This recorder is provided with the sensor for measuring the exposure of each output part of a PLZT head on an opposite side to the PLZT head with respect to photographic paper.

Title: Gas sensor
Inventor: SAWADA AKIRA
IPC: G01N21/39
Filed: 1987-05-07
Abstract: PURPOSE:To suppress noises due to optical standing waves, by making the amplitude of wavelength modulation to be X times the interval of the optical standing wave, which is generated in an optical system. CONSTITUTION:A sawtooth wave signal having a specified period is generated 21 and supplied to a laser 1 as a bias current. The oscillating wavelength of the signal is determined. The oscillating output undergoes A/D conversion 22 and the result is inputted into a ROM 25. The data of the modulating amplitude from the ROM 25 are read. D/A conversion 24 of the data is performed. The result is multiplied 29 by the amplitude of a sine wave from an oscillator 23. The amplitude of the sine wave is changed at every oscillating wavelength. Thus condition, under which X times of the period of the optical standing wave that is generated in an optical system are obtained, is satisfied in all wavelength [X satisfies J2(piXX)=0 and J is a quadratic Bessel function]. The multiplied output and the sawtooth signal are added 26, and the current of the laser 1 is set. As a result, noises due to the optical standing waves, which are generated in a long optical path cell 28 for measuring gas to be measured 2, can be suppressed.

Title: Infrared ray reflective material
Inventor: OGAWA SOICHI
IPC: G02B5/26
Filed: 1986-05-16
Abstract: PURPOSE:To obtain an IR ray reflective material which does not require mirror finishing by forming an intermediate layer consisting of a pure metal or alloy onto the surface of a substrate which is specified in surface roughness and forming a film consisting of zirconium nitride on the intermediate layer. CONSTITUTION:The surface roughness of the substrate is specified to <=1mum. The reason for such specification lies in that the zirconium film on the surface is not smooth if the surface roughness is rougher than 1mum as both the intermediate layer and the zirconium nitride film are thinly formed. Zirconium is preferable as the pure metal for the intermediate layer and the thickness is required to be >=10Angstrom  in order to improve the adhesiveness of the zirconium nitride. The thickness is specified more preferably to 100-5,000Angstrom . The zirconium nitride film is formed to the compsn. range of Zr1Nx (0.7<x<1.5). The reason for such range lies in that the film has the metallic gloss of the zirconium and the reflectivity decreases, if the ratio of the nitrogen to the zirconium 1 is <=0.7. The absorption of rays increases and the reflectively decreases conversely if the ratio is >=1.5.

IPC: G03G15/16
Filed: 1991-04-18
Abstract: PURPOSE:To prevent toner scattering at a transfer time and to obtain an image of good quality by reinforcing the bonding of toner powder by heating the toner for forming a toner image before transfer. CONSTITUTION:Viewing from an image carrier traveling direction, a heater H is arranged on the upstream of a transfer position where an image carrier and a transfer electrostatic charger 2 face oppositely and adjacent to the surface of the image carrier. Thus, the toner T1 for forming the toner image is heated by the heater H, and by properly adjusting the heating state, the toner particles on the surface are solidified in an almost mutually melt-sticking state, and then, it becomes the toner T2 having clayey texture. By constituting in such a way, even in the case that an electrical field is formed on a gap position (a) as a position just before the transfer by a charge leak to a part of the transfer material, the electrical field is a small one, so that the scattering of the toner whose particles are not minute and light does not occur. And the toner T2 moves in a block state, so that residual toner remaining on the image carrier is reduced.
