Title: Constant current circuit
Inventor: MATSUURA TATSUJI
IPC: G05F3/24
Filed: 1983-04-15
Abstract: PURPOSE:To obtain a constant current source which has no variation of the set current despite the variation of the threshold voltage of a constant current generating transistor TR, by using a voltage source which varies in response to the variation of the threshold voltage of said TR. CONSTITUTION:A voltage dividing circuit consisting of transistor FET12-15 is provided between a power supply VDD10 and a power supply VSS11. The output voltage 21 of the voltage dividing circuit is supplied to a constant current generating FET20. Then the voltage 21 varies in response to the variation of the threshold voltage of the FET20. Thus it is possible to obtain a constant current source which has no variation of the set current despite the variation of the threshold voltage of the TR.

Title: Data broadcasting receiver
Inventor: HAYASHI TERUTAKA
IPC: G06F13/00
Filed: 1995-03-24
Abstract: PURPOSE: To provide a data broadcasting receiver capable of checking errors without burdening a CPU so much. CONSTITUTION: Bit stream signals inputted from a BS tuner are converted to the data signals of a packet unit and then, separated to prefix data and data group data. Here, the presence/absence of the errors of the data group data are detected by an error detection circuit, an error flag is inserted to the prefix data and they are stored in a prefix memory and a data memory. In the case where the respective data stored in the prefix memory and the data memory are transferred to a memory circuit to be used in a video game machine, an OR loop 483 ORs the error flag read out of the prefix memory in the time base direction and stores the result in a D-FF 486. The CPU refers to the stored ORed result and confirms whether or not the error is present in the data group data.

Title: Side guard lace of car
Inventor: MIURA EIICHI
IPC: B32B3/10
Filed: 1981-04-30
Abstract: PURPOSE:To reinforce outside plate without the increase of weight, by hardening lace stock which is flexible before fixture after attaching it to the outside plate while matching it to the shape of the outside plate. CONSTITUTION:Lace stock 1a is formed by laying a core material 3 under a reinforcing resin layer 2, and fitted by attaching its fitting surface 21 formed longitudinally on the reinforcing resin layer 2 to outside plate A. The reinforcing resin layer 2 is flexible in unhardened or half hardened condition. Besides, the core material 3 is made of a foaming material which does not foam before fitting lace stock 1a and foams after fitting it. When the lace stock 1a is heated after fitting it to the outside plate A, the core material 3 foams.

Title: Driving state output device
Inventor: KATAOKA ICHIRO
IPC: G08B21/00
Filed: 1994-04-04
Abstract: PURPOSE:To reduce the load on driver for checking a device and to improve the safety of travel by making visual recognition of the output state of a driving state output device unnecessary. CONSTITUTION:The driving state output device is provided with motors 9, 13 for rotating foot rests 3, 4, an ECU 16, a distance sensor 17, a speed sensor 18, a road face detecting sensor 19, and a steering operation amount sensor 20.

Title: Liquid crystal display body
Inventor: HOSHIKAWA JIYUN
IPC: G02F1/1335
Filed: 1983-04-14
Abstract: PURPOSE:To make cell thickness and response speed uniform, to suppress generation of Newton's rings and to make the range of a visual angle wider and the thickness smaller by constituting a liquid display body of the substrates formed with members having different coeffts. of expansion into one body. CONSTITUTION:The upper plastic film 12 of the 1st electrode substrate 1 sandwiching a polarizing film 11 has the coefft. of expansion larger than the coefft. of expansion of a lower film 13 and therefore when said substrate is adhered by an adhesive layer to the 2nd electrode substrate 7 at a high temp. and is allowed to cool to a room temp., the outside thereof is going to curve on the side opposite form a liquid crystal layer 6 but since the substrate 7 is a glass plate and is hardly curved by an environmental change, the substrate 1 is held by spacers 5 and is thus prevented from deforming. The 3rd electrode substrate 2 formed into one body at a high temp. is going to curve into a recessed shape on the side opposite from the layer 6, in the same way as with the substrate 1 because the coefft. of expansion of a plastic film 23 laminated on the liquid 6 side of said substrate is smaller than the coefft. of expansion of a reflecting body 25, but the substrate 2 is held by the spacers 5 and is prevented from deforming. The laminated two layers 6 are thus made respectively uniform.

A cooling air 46d is introduced from the exterior part of a bell mouth 1, runs through an annular spacing between the cooling pipe 33 and the fiberscope 35 and a jet of such air is applied through the forward end of the cooling pipe 33 into the space of the tail pipe 11. The jet of the air 46d, a so-called purge air, is delivered in order to minimize the amount of the combustion gas coming in direct contact with a heat resisting quartz glass 41 and to prevent soot particles in the combustion gas from adhering to the heat resisting quartz glass 41. Since this structure permits flame in the inner pipe to be viewed directly as a flame image, a state of balance between flame vibration, firing and extinction and flame color can be monitored.

Title: Laser distance measuring apparatus
Inventor: KATOU KIICHIROU
IPC: G01S17/10
Filed: 1994-04-05
Abstract: PURPOSE:To reduce the distance measuring errors due to rising time by repeating the measurement of distance while reducing the opening area of a receiving optical system, and to taking distance information before the measurement of the distance at which a counter overflowed. CONSTITUTION:A control counting section 7 determines distance information to a target from a time difference between a starting signal and a stopping signal to be stored into a memory 16. A signal a1 is sent simultaneously with the inputting of the stopping signal to reduce an opening area by a fixed value with an opening choke 15 and then, a signal b1 is sent of a laser oscillator 1 to implement the measuring of a distance for the same target again. This operation is repeated until the counter of the counting section 7 overflows. The opening area of the optical system 4 reduces and as the stopping signal of an amplifier 6 falls below a threshold, an overflow takes place in the counter. Distance information during the measuring of a distance before the overflow is sent to a display section 8 to be displayed. The distance information is given when an output level of the amplifier 6 exceeds a threshold slightly, thereby the rising time can be always kept constant.
