IPC: H01L21/203
Filed: 1985-12-05
Abstract: PURPOSE:To prevent the dislodgment of a target material from a supporting member by melting of a brazing filler metal by forming a gas venting hole to the target material and supporting member joined by the brazing filler metal and disposing a coupling member into the hole. CONSTITUTION:The target material 1 is supported by the supporting member 2 via the brazing filler metal 3 in a plasma sputtering vapor deposition device. The gas venting screw hole 9 is preliminarily formed to such supporting member 2 and target material prior to working. The screw member 10 is screwed into the screw hole 9 after brazing to connect and fix the target material 1 and the supporting member 2. The target material 1 is thus prevented from being dislodged from the supporting member 12 even if the brazing filler metal 3 is melted by the heat generated when the plasma ions collide against the target material 1. The generated gas is effectively liberated from the hole 9.

Title: Optical disc apparatus
Inventor: SHIGEMORI TOSHIHIRO
IPC: G11B7/00
Filed: 1993-10-08
Abstract: PURPOSE:To simultaneously conduct recording and reproducing operations by detecting intensity change of the light reflected from an optical disc and reproducing information of an adjacent track by extracting only changing element depending on on the information of the adjacent track on the occasion of recording information to the object track of the optical disc. CONSTITUTION:When the track k+1 is irradiated with an optical beam, the reflected beams irradiating the tracks k and k+2 due to diffraction of light beam change the intensity depending on the pieces of information b and a. When a pickup detects the change of intensity and an output S2 of a reproducing circuit 4 and the beam irradiates the track k, in regard to the output 82 of a reproducing circuit 4, information included in the reflected light beam becomes unstable due to the influence of the track k-1. A differential circuit 5 outputs a differential signal S3 between the signals S2 and S1. A binarizing circuit 6 binarizes a signal to output the signal S4. An error detecting signal 4 checks an error of the signal S4 to output both result and information. Thereby, information can be recorded to one track and recorded information can also be read simultaneously from another track. Use of only one pickup 2 does not result in cost-up.

Title: Reading/writing device for ic card
Inventor: TAKIMOTO YOZO
IPC: G06K17/00
Filed: 1987-10-31
Abstract: PURPOSE:To always secure the proper contact pressure by permitting the pass of an IC card only when this card has its thickness within an allowable range and securing a contact between the card and the contact of a contact head. CONSTITUTION:In case an IC card 100 is too thick or thin, a stopper 43 of a cut-off means cuts off a guide path 13 to inhibit the pass of the card 100. Thus the card 100 does not touch a contact 17a of a contact head 17 and therefore no writing/reading action is carried out. Then the card 100 can pass through the path 13 only in case the thickness of the card 13 is set within an allowable range. Thus the card 100 has a contact with the contact 17a. As a result, the proper contact pressure is always secured for the card 100 so that the sure reading and writing actions are ensured. At the same time, the damage of the contact 17a and the contact wear of the card 100 can be avoided.

Abstract: PURPOSE:To guarantee range-finding precision and to shorten releasing time lag by operating necessary focusing precision from the focal length information of a photographing lens and diaphragm value information required from brightness and the sensitivity of a film, and determining the number of range-finding times. CONSTITUTION:A photometric means 2 meters the brightness of an object, and a diaphragm value at the time of photographing is operated with the metered brightness and the film sensitivity detected by a film sensitivity detecting means 3, by a diaphragm value operating means 5. On the other hand, the focal length of the photographing lens is required by a focal length detecting means 1, and a means for operating the number of the range-finding times 5 operates the focusing precision required for the photographing by the required focal length and the output of the diaphragm value of the means 4, and determines the number of the range-finding times (n). A range-finding means 6 is operated according to the output of the means 5, and carries out the range- finding of n-number times, to obtain the average value of the measured value. Thus, the range-finding precision required for the photographing is guaranteed, and simultaneously, the releasing time lag can be shortened.

Title: Multicolor thermosensitive recording material
Inventor: OHASHI MIHO
IPC: B41M5/333
Filed: 1986-11-19
Abstract: PURPOSE:To obtain a high-quality multicolor developed image with a low temperature color deleloping layer which has a significantly improved color development and discharging properties by using compounds such as bis(3-chloro-4- hydroxyphenyl)ethylacetate as developers. CONSTITUTION:In multicolor thermosensitive recording materials consisting of at least one kind of decoloring agent and at least two kinds of dye and developer, for instance, a compound such as bis(3-chloro-4-hydroxyphenyl) ethylacetate shown by the formula I is incorporated as the developer. A leuco dye is used alone or in a mixture of two or more kinds of other chemical, for instance 3,3-bis(p-dimethylaminophenyl)-phthalide may be mentioned. The color development of a low temperature color-developing layer needs to be prevented when a color is developed at high temperatures. A such decoloring agent, for instance, N-methyl-N'-phenylacetylpiperazine is named. In order to obtain a bicolor thermosensitive recording material, a solution containing dispersed or dissolved color developing dye, developing agent, decoloring agent and bider is applied to the surface of a support such as paper, synthetic paper and plastic and dried. The process is repeated to obtain the bicolor thermosensitive recording material.
