Title: Plastic character eraser
Inventor: KUWABARA HIDEO
IPC: B43L19/00
Filed: 1988-07-08
Abstract: PURPOSE:To increase the erasion of traces of black and color pencil leads with low density by adding a mixture of vinyl chloride resin, a plasticizer, a stabilizer and an inorganic filler and giving a specific concentration of a porous inorganic substance to the inorganic filler. CONSTITUTION:To increase the erasion of traces of black and color pencil leads with low density by a plastic character eraser using vinyl chloride resin on a plastic base, a porous inorganic substance, with many fine pores and voids, which does not indicate any molecular flocculation structurally is used as part of an inorganic filler for a plastic character eraser composition. For the addition of this porous inorganic substance, the required amount is equivalent to 20-55% of the total amount of the inorganic filler. If 20% or less, the plastic character eraser is short of reaching the required level of hardness in terms of quality as the conventional eraser is. If the percentage is 55% or more, the hardness increases but the characteristics of vinyl chloride resin in the plastic character eraser are deteriorated. Consequently, the shortcoming is apparent that erasure waste produced by abrasion increases more than necessary. In addition, the casting of the plastic resin into the forms becomes difficult due to the high viscosity of plastic sols in a manufacturing process.

Abstract: PURPOSE: To confirm the running state of a program, by providing a control means which identifies an instruction to switch on and off a lamp and then switches on and off the lamp and replacing an optional instruction of a route of the program with an instruction to switch on or off the lamp.  
     CONSTITUTION: A lamp switch-on instruction LON and a lamp switch-off instruction LOF are put into addresses 0100 and 0500 respectively of a program in a memory device MEM. The original instruction is previously saved in a lamp-on register LONR and a lamp-off register LOFR respectively. When a program is started and reaches the address 0100, the instruction LON is supplied to an instruction register IR via a memory buffer register MBR and analyzed by a decoder DEC. This analyzed instruction is supplied to an AND gate and a timing circuit T through a control line 1, and opens the AND gate to go into an FF and to switch on a lamp LAP. The output signal (a) of the circuit T stores the original instruction in an instruction register IR through the LONR to the MBR and executes the instruction. An address 0500 is processed in the same way.

Title: Liquid fuel burner
Inventor: SHIRODE KOSAKU
IPC: F23D11/24
Filed: 1990-06-27
Abstract: PURPOSE:To prevent the liquid fuel which is once evaporated and liquefied from condensing on the wall face of an evaporation chamber by providing a supply channel for heated air that is sent to an evaporation chamber in the form by which the outer circumference of the evaporation chamber is surrounded by the supply channel. CONSTITUTION:The outer circumference of an evaporation chamber 10 is surrounded by a heated air supply channel 20. With this arrangement the heated air that is sent into the evaporation chamber 10 heats the evaporation chamber 10 from outside before the heated air is sent into the evaporation chamber 10. The evaporation chamber 10 is, therefore, heated at its wall not only from inside but also from outside. As a result the liquid fuel that is once evaporated is prevented from being condensed on the inner wall face of the evaporation chamber 10. And, since the evaporation chamber 10 is heated also by the heated air from the outside as well, the temperature rise in the wall face of the evaporation chamber 10 in the initial stage of the operation becomes fast so that the start-up of operation becomes very good.

Title: Multilayered antireflection film
Inventor: KIYONO MINORU
IPC: G02B5/28
Filed: 1979-12-28
Abstract: PURPOSE: To obtain the band of a minimum reflectance by forming films of at least three layers on a substrate, making the refractive index of the intermediate film higher than that of the other films, and providing predetermined relations with respect to the central wavelength of the target band to the thicknesses of the respective films.  
     CONSTITUTION: Antireflection films of 4 layers, films 1W4, are formed on a substrate 5, and the refractive indexes of these films are defined as n 1 Wn 4 , and optical  film thicknesses as d 1 Wd 4 . The term "optical film thickness" refers to physical  film thickness x refractive index. Making a film nonreflecting necessitates satisfying  the conditions of the formula I or formula II. Now, if the temporal center wavelength of a desired band is defined as λ 0 ', the central wavelength as λ 0 , b=λ 0 /λ 0 ' and (a) as the value at the optical film thickness (1-a)λ 0 '/2 of the 2nd layer in which the central wavelength λ 0  assumes a minimum reflectance, these are so arranged as to have the relations of the formulas III, IV, whereby the band of a minimum reflectance is obtained. Since this is accomplished by controlling the film thicknesses, the degree of freedom in the selection of materials is increased and the films of high hardness are obtained depending upon applications.

Title: Disk reproducing device
Inventor: NAKAGAKI HARUSHIGE
IPC: G11B7/09
Filed: 1983-09-19
Abstract: PURPOSE:To reduce the occurrence of track jump caused by a scratch on a disk, by installing a state discriminator and using the detection signal of the negative feedback area of tracks only for the control of a loop switch when a tracking servo is pulled in. CONSTITUTION:A state discriminator 24 outputs a signal of ''Low'' when the pulling-in operation of a tracking servo is made and another signal of a ''High'' when a disk is played after the pulling-in operation of the tracking servo is terminated. Since the negative feedback detecting signal (b) of a track is outputted to the output of an OR circuit 25 at the time of pulling-in of the track servo, a loop switch 11 is driven only in the negative feedback area of the track and a stable pulling-in of a loop is made. When a disk is reproduced after the pulling-in of the track is terminated, the control signal of the state discriminator 24 is inverted from ''Low'' to ''High''. Therefore, the output of the OR circuit 25 is maintained at ''High'' even when the track negative feedback detecting signal becomes ''Low'' due to a scratch on the disk and the loop switch 11 is never turned off. As a result, the hit of the servo loop can be eliminated.
