Abstract: PURPOSE:To make the intensity of the reflecting light at a canti-lever larger and to improve the resolution of a detecting mechanism in the detecting mechanism of an optical lever system, by setting the thickness of a thin film to form the cantilever in a specific value in the relation with the wave length and the incident angle of the light used in the detecting mechanism, and the refraction factor of the thin film. CONSTITUTION:To utilize the resolution of a detecting mechanism 20 of an optical lever system maximum, the film thickness of a canti-lever 11 is deigned in consideration of the wave length and the incident angle of the light. That is, the thickness of the thin film to form the cantilever 11 is set to make the reflection light from the thin film intensified by interferences. Practically, when the cantilever is a single layer thin film, the refraction factor of the thin film is made n, the wave length used in the detecting mechanism is made lambda, the incident angle is made theta, and the film thickness d is set as shown in the formula I, where m is a random integral number. As a result, the intensity of the reflection light in the cantilever 11 in the optical lever system can be made stronger, and the resolution of the detecting mechanism can be improved.

Title: Recording material
Inventor: HARADA TORU
IPC: B41M5/327
Filed: 1986-10-30
Abstract: PURPOSE:To obtain a recording material capable of forming clear color images having excellent light fastness, by incorporating a specified leuco coloring matter. CONSTITUTION:A leuco coloring matter (yellow image-forming substance) of general formula [Ia] or [Ib] is used as a color image-forming substance in a recording material, whereby images with a high maximum density and a low minimum density, namely, with a high S/N can be obtained. The color images thus obtained have excellent light fastness. Therefore, when images are forming by using the recording material, extremely clear color images can be obtained which are substantially insusceptible to fading under light and are capable of enduring preservation for a long time. The effect of the leuco coloring matter is conspicuous particularly when the coloring matter is used in a photosensitive recording material comprising a silver halide, a reducing agent and a polymeric compound.

Abstract: PURPOSE:To accomplish printing without causing faulty fixing by providing a 2nd temperature detection means at a specified position in an image forming device in addition to a 1st temperature detection means which abuts on the surface of a fixing roller and a means for detecting the size of a transfer material. CONSTITUTION:The 2nd temperature detection means 12 is provided at the specified position in this image forming device in addition to the 1st temperature detection means 6 disposed so as to abut on the surface of the fixing roller 2 and the paper size detecting means 15 for detecting the size of the transfer material is also provided.

In the case that the detected temperature exceeds the limit temperature, the energizing of the heater 3 is stopped. Even when a cooling fan 9 is stopped in the midst of a printing action, the printing action is not stopped, then the excessive temperature rise in the image forming device is prevented, and the excellent fixing is performed regardless of the size of the transfer material.

Title: Semiconductor lead frame with excellent resin close-contact performance
Inventor: WATANABE RIKIZO
IPC: H01L23/50
Filed: 1987-10-15
Abstract: PURPOSE:To obtain a lead frame whose close contact performance with reference to a resin has been enhanced without lowering plating performance and soldering performance by a method wherein an amount of C measured by using an X-ray photoelectron spectroscopic analytical method on the surface obtained by removing a range of 10Angstrom  from the surface of an object to be tested is contained at less than a specific amount. CONSTITUTION:An amount of C measured in the surface obtained by removing a range of 10Angstrom  from the surface of an object to be tested by using an X-ray photoelectron spectroscopic analytical method is made to be 20 atomic % or below in order to check a situation contaminated by C, the surface is sputtered for one minute; the surface is removed by about 10Angstrom ; this surface is analyzed; when the close contact performance with reference to a resin is good, 20 atomic % or below of C is contained; when the close contact performance is bad, C exceeding 20 atomic % is contained. At a face at about 30Angstrom  from the outermost surface, a part contaminated by C and O is almost removed irrespective of whether the close contact performance is good or bad. In order to reduce contamination by C on the surface of a lead frame, an annealing method in dry hydrogen, a careful cleaning method by using a surfactant and an organic solvent or the like is effective.

Title: Magnetic storage device
Inventor: TANAKA TAKESHI
IPC: G11B5/09
Filed: 1989-10-04
Abstract: PURPOSE:To make a rotary drum smaller in diameter and miniaturized by deciding whether a data stored in a read part of a magnetic tape under traveling is the data in an area required for read-out or not and reading only the data in the required area. CONSTITUTION:A reproducing signal is outputted in response to a rise signal of a fundamental waveform to be outputted by a signal processing circuit 112, and a counter 101 is started to count. On the other hand, count values corresponding to changeover values from a subcode area 1 to a main code area and from the main code area to a subcode area 2 are stored in a memory 102. Then, when the coincidence of this stored value and the counted value is decided by a deciding device 103, a read starting or ending changeover signal is outputted from an output device 104, and a read signal is taken out via a read switch 111 and an amplifier circuit 110 only during such a period that a recording signal and the reproducing signal are not overlapped with each other. Consequently, even when the recording signal and the reproducing signal are partially overlapped with each other, no cross-talk should take place. By this method, the rotary drum can be made smaller in diameter and also miniaturized.
